目標(biāo)
本文的主要的目標(biāo)是幫助你使用 Unity 創(chuàng)建 iOS 原生彈框。

你會(huì)得到的最終效果如下圖

你想要遵循 iOS 的標(biāo)準(zhǔn)來(lái)顯示彈框嗎？

你想要移除額外的圖形來(lái)減小你構(gòu)建應(yīng)用的大小嗎？

你想要從 Unity 中顯示原生的彈框來(lái)提高用戶體驗(yàn)嗎？

如果你有這些疑慮，那么現(xiàn)在你來(lái)對(duì)地方了。在這篇博客中，我將使用 Unity 創(chuàng)建 iOS 原生彈框。

第一步 介紹

彈框是一種小的遮擋或者提示用戶做一些操作的警告信息。

在這兒，我們將創(chuàng)建3種類型的彈框

現(xiàn)在讓我們創(chuàng)建一些簡(jiǎn)單的彈窗吧！

第二步 在 Unity 中設(shè)置場(chǎng)景

創(chuàng)建新的 Unity 工程，然后保存場(chǎng)景到你的資源文件夾中。

為三個(gè)彈框創(chuàng)建三個(gè)按鈕

第三步 創(chuàng)建腳本然后分配所有按鈕的引用

創(chuàng)建一個(gè)腳本然后給它命名。我命名為 PopupView.cs ，現(xiàn)在讓我們?cè)诖a中添加一個(gè)按鈕點(diǎn)擊的監(jiān)聽(tīng)事件。

為每一個(gè)按鈕創(chuàng)建一個(gè)方法并且在按鈕點(diǎn)擊事件添加引用。從 iOS 的對(duì)話行為中返回一個(gè)枚舉存儲(chǔ)消息的狀態(tài)。

public enum MessageState
{
    OK,
    YES,
    NO,
    RATED,
    REMIND,
    DECLINED,
    CLOSED
}   

#region PUBLIC_VARIABLES

//在你想要評(píng)價(jià)的應(yīng)用創(chuàng)建一個(gè)變量來(lái)保持 appID
public string appleId = "925623445";
#endregion

#region BUTTON_EVENT_LISTENER

// 會(huì)話按鈕點(diǎn)擊事件
public void OnDialogPopUp() {
    NativeDialog dialog = new NativeDialog("TheAppGuruz", "Do you wants to know about TheAppGuruz");
    dialog.SetUrlString("http://theappguruz.com/");
    dialog.init();
}

// 評(píng)價(jià)按鈕點(diǎn)擊事件
public void OnRatePopUp()
{
    NativeRateUS ratePopUp = new NativeRateUS("Like this game?", "Please rate to support future updates!");
    ratePopUp.SetAppleId(appleId);
    ratePopUp.InitRateUS();
}

// 消息按鈕點(diǎn)擊事件
public void OnMessagePopUp()
{
    NativeMessage msg = new NativeMessage("TheAppGuruz", "Welcome To TheAppGuruz");
}
#endregion

現(xiàn)在讓我們?yōu)樵膹椏蛐袨樽?cè)委托事件監(jiān)聽(tīng)者。

#region UNITY_DEFAULT_CALLBACKS

void OnEnable()
{
    // 注冊(cè)所有的委托事件監(jiān)聽(tīng)者
    IOSRateUsPopUp.onRateUSPopupComplete += OnRateUSPopupComplete;
    IOSDialog.onDialogPopupComplete += OnDialogPopupComplete;
    IOSMessage.onMessagePopupComplete += OnMessagePopupComplete;
}

void OnDisable()
{
    // 注銷所有的委托事件監(jiān)聽(tīng)者
    IOSRateUsPopUp.onRateUSPopupComplete -= OnRateUSPopupComplete;
    IOSDialog.onDialogPopupComplete -= OnDialogPopupComplete;
    IOSMessage.onMessagePopupComplete -= OnMessagePopupComplete;
}

#endregion

#region DELEGATE_EVENT_LISTENER

// 當(dāng)點(diǎn)擊評(píng)價(jià)彈框的按鈕時(shí)會(huì)輸出不同的狀態(tài)
void OnRateUSPopupComplete(MessageState state)
{
    switch (state)
    {
        case MessageState.RATED:
        Debug.Log("Rate Button pressed");
        break;
        case MessageState.REMIND:
        Debug.Log("Remind Button pressed");
        break;
        case MessageState.DECLINED:
        Debug.Log("Declined Button pressed");
        break;
    }
}

// 當(dāng)點(diǎn)擊會(huì)話彈框的按鈕時(shí)會(huì)輸出不同的狀態(tài)
void OnDialogPopupComplete(MessageState state)
{
    switch (state)
    {
        case MessageState.YES:
        Debug.Log("Yes button pressed");
        break;
        case MessageState.NO:
        Debug.Log("No button pressed");
        break;
    }
}

// 當(dāng)點(diǎn)擊消息彈框的按鈕時(shí)會(huì)輸出不同的狀態(tài)
void OnMessagePopupComplete(MessageState state)
{
    Debug.Log("Ok button Clicked");
}
#endregion

第四步 創(chuàng)建腳本和 Objective-c 代碼的相互作用

現(xiàn)在，創(chuàng)建一個(gè)腳本命名為 IOSNative.cs 來(lái)直接和 iOS 代碼（Objective-c）進(jìn)行交互。

#define DEBUG_MODE

using UnityEngine;
using System.Collections;

#if (UNITY_IPHONE && !UNITY_EDITOR) || DEBUG_MODE
using System.Runtime.InteropServices;
#endif

public class IOSNative
{
    #if (UNITY_IPHONE && !UNITY_EDITOR) || DEBUG_MODE
    [DllImport("__Internal")]
    private static extern void _TAG_ShowRateUsPopUp(string title, string message, string rate, string remind, string declined);

    [DllImport("__Internal")]
    private static extern void _TAG_ShowDialog(string title, string message, string yes, string no);

    [DllImport("__Internal")]
    private static extern void _TAG_ShowMessage(string title, string message, string ok);

    [DllImport("__Internal")]
    private static extern void _TAG_RedirectToAppStoreRatingPage(string appId);

    [DllImport("__Internal")]
    private static extern void _TAG_RedirectToWebPage(string urlString);

    [DllImport("__Internal")]
    private static extern void _TAG_DismissCurrentAlert();

    #endif

public static void showRateUsPopUP(string title, string message, string rate, string remind, string declined)
{
    #if (UNITY_IPHONE && !UNITY_EDITOR) || DEBUG_MODE
    _TAG_ShowRateUsPopUp(title, message, rate, remind, declined);
    #endif
}

public static void showDialog(string title, string message, string yes, string no)
{
    #if (UNITY_IPHONE && !UNITY_EDITOR) || DEBUG_MODE
    _TAG_ShowDialog(title, message, yes, no);
    #endif
}

public static void showMessage(string title, string message, string ok)
{
    #if (UNITY_IPHONE && !UNITY_EDITOR) || DEBUG_MODE
    _TAG_ShowMessage(title, message, ok);
    #endif
}

public static void RedirectToAppStoreRatingPage(string appleId)
{
    #if (UNITY_IPHONE && !UNITY_EDITOR) || DEBUG_MODE
    _TAG_RedirectToAppStoreRatingPage(appleId);
    #endif
}

public static void RedirectToWebPage(string urlString)
{
    #if (UNITY_IPHONE && !UNITY_EDITOR) || DEBUG_MODE
    _TAG_RedirectToWebPage(urlString);
    #endif
}

public static void DismissCurrentAlert()
{
    #if (UNITY_IPHONE && !UNITY_EDITOR) || DEBUG_MODE
    _TAG_DismissCurrentAlert();
    #endif
}
}

第五步 為不同的彈框創(chuàng)建腳本

正如我上面所提到的，我們將創(chuàng)建三種類型的彈框，讓我們創(chuàng)建腳本來(lái)創(chuàng)建不同的彈框。

消息彈框

A) 創(chuàng)建 NativeMessage.cs 腳本為簡(jiǎn)單的消息彈框做一些基本設(shè)置。

public class NativeMessage
{
#region PUBLIC_FUNCTIONS

public NativeMessage(string title, string message)
{
init(title, message, "Ok");
}

public NativeMessage(string title, string message, string ok)
{
init(title, message, ok);
}

private void init(string title, string message, string ok)
{
#if UNITY_IPHONE
IOSMessage.Create(title, message, ok);
#endif
}
#endregion
}

B) 為簡(jiǎn)單消息彈框創(chuàng)建 IOSMessage.cs 腳本

public class IOSMessage : MonoBehaviour
{           
#region DELEGATE
public delegate void OnMessagePopupComplete(MessageState state);
public static event OnMessagePopupComplete onMessagePopupComplete;

    #endregion

    #region DELEGATE_CALLS

    private void RaiseOnMessagePopupComplete(MessageState state)
    {
        if (onMessagePopupComplete != null)
            onMessagePopupComplete(state);
    }

    #endregion

    #region PUBLIC_VARIABLES

    public string title;
    public string message;
    public string ok;

    #endregion

    #region PUBLIC_FUNCTIONS

    public static IOSMessage Create(string title, string message)
    {
        return Create(title, message, "Ok");
    }

    public static IOSMessage Create(string title, string message, string ok)
    {
        IOSMessage dialog;
        dialog = new GameObject("IOSMessagePopUp").AddComponent<IOSMessage>();
        dialog.title = title;
        dialog.message = message;
        dialog.ok = ok;
        
        dialog.init();
        return dialog;
    }

    public void init()
    {
        IOSNative.showMessage(title, message, ok);
    }

    #endregion

    #region IOS_EVENT_LISTENER

    public void OnPopUpCallBack(string buttonIndex)
    {
        RaiseOnMessagePopupComplete(MessageState.OK);
        Destroy(gameObject);
    }

    #endregion
}

確認(rèn)彈框

A) 創(chuàng)建 NativeDialog.cs 腳本為會(huì)話的消息彈框做一些基本設(shè)置。

public class NativeDialog
{
    #region PUBLIC_VARIABLES
    string title;
    string message;
    string yesButton;
    string noButton;
    public string urlString;
    #endregion

    #region PUBLIC_FUNCTIONS
    public NativeDialog(string title, string message)
    {
        this.title = title;
        this.message = message;
        this.yesButton = "Yes";
        this.noButton = "No";
    }

    public NativeDialog(string title, string message, string yesButtonText, string noButtonText)
    {
        this.title = title;
        this.message = message;
        this.yesButton = yesButtonText;
        this.noButton = noButtonText;
    }

    public void SetUrlString(string urlString)
    {
        this.urlString = urlString;
    }

    public void init()
    {
        #if UNITY_IPHONE
        IOSDialog dialog = IOSDialog.Create(title, message, yesButton, noButton);
        dialog.urlString = urlString;
        #endif
    }
    #endregion
}

B) 為會(huì)話消息彈框創(chuàng)建 IOSDialog.cs 腳本

public class IOSDialog : MonoBehaviour
{
    #region DELEGATE
    public delegate void OnDialogPopupComplete(MessageState state);
    public static event OnDialogPopupComplete onDialogPopupComplete;
    #endregion

    #region DELEGATE_CALLS
    private void RaiseOnOnDialogPopupComplete(MessageState state)
    {
        if (onDialogPopupComplete != null)
            onDialogPopupComplete(state);
    }
    #endregion

    #region PUBLIC_VARIABLES
    public string title;
    public string message;
    public string yes;
    public string no;
    public string urlString;
    #endregion

    #region PUBLIC_FUNCTIONS
    // Constructor
    public static IOSDialog Create(string title, string message)
    {
        return Create(title, message, "Yes", "No");
    }

    public static IOSDialog Create(string title, string message, string yes, string no)
    {
        IOSDialog dialog;
        dialog = new GameObject("IOSDialogPopUp").AddComponent<IOSDialog>();
        dialog.title = title;
        dialog.message = message;
        dialog.yes = yes;
        dialog.no = no;
        dialog.init();
        return dialog;
    }

    public void init()
    {
        IOSNative.showDialog(title, message, yes, no);
    }
    #endregion

    #region IOS_EVENT_LISTENER
    public void OnDialogPopUpCallBack(string buttonIndex)
    {
        int index = System.Convert.ToInt16(buttonIndex);
        switch (index)
        {
            case 0: 
                IOSNative.RedirectToWebPage(urlString);
                RaiseOnOnDialogPopupComplete(MessageState.YES);
                break;
            case 1: 
                RaiseOnOnDialogPopupComplete(MessageState.NO);
                break;
        }
        Destroy(gameObject);
    }
    #endregion
}

評(píng)價(jià)我們彈框

A) 創(chuàng)建 NativeRateUS.cs 腳本為評(píng)價(jià)我們的彈框做一些基本設(shè)置。

public class NativeRateUS
{
   #region PUBLIC_VARIABLES
    public string title;
    public string message;
    public string yes;
    public string later;
    public string no;
    public string appleId;
    #endregion

    #region PUBLIC_FUNCTIONS
    // Constructor
    public NativeRateUS(string title, string message)
    {
        this.title = title;
        this.message = message;
        this.yes = "Rate app";
        this.later = "Later";
        this.no = "No, thanks";
    }

    // Constructor
    public NativeRateUS(string title, string message, string yes, string later, string no)
    {
        this.title = title;
        this.message = message;
        this.yes = yes;
        this.later = later;
        this.no = no;
    }
    // Set AppID to rate app
    public void SetAppleId(string _appleId)
    {
        appleId = _appleId;
    }
    
    // Initialize rate popup
    public void InitRateUS()
    {
        #if UNITY_IPHONE
        IOSRateUsPopUp rate = IOSRateUsPopUp.Create(title, message, yes, later, no);
        rate.appleId = appleId;
        #endif
    }
    #endregion
}

B) 為評(píng)價(jià)我們彈框創(chuàng)建 IOSRateUsPopUp.cs 腳本

public class IOSRateUsPopUp : MonoBehaviour
{
    #region DELEGATE
    public delegate void OnRateUSPopupComplete(MessageState state);
    public static event OnRateUSPopupComplete onRateUSPopupComplete;
    #endregion

    #region DELEGATE_CALLS
    private void RaiseOnOnRateUSPopupComplete(MessageState state)
    {
        if (onRateUSPopupComplete != null)
            onRateUSPopupComplete(state);
    }

    #endregion

    #region PUBLIC_VARIABLES
    public string title;
    public string message;
    public string rate;
    public string remind;
    public string declined;
    public string appleId;
    #endregion

    #region PUBLIC_FUNCTIONS
    public static IOSRateUsPopUp Create()
    {
        return Create("Like the Game?", "Rate US");
    }

    public static IOSRateUsPopUp Create(string title, string message)
    {
        return Create(title, message, "Rate Now", "Ask me later", "No, thanks");
    }

    public static IOSRateUsPopUp Create(string title, string message, string rate, string remind, string declined)
    {
        IOSRateUsPopUp popup = new GameObject("IOSRateUsPopUp").AddComponent<IOSRateUsPopUp>();
        popup.title = title;
        popup.message = message;
        popup.rate = rate;
        popup.remind = remind;
        popup.declined = declined;
        popup.init();
        return popup;
    }

    public void init()
    {
        IOSNative.showRateUsPopUP(title, message, rate, remind, declined);
    }
    #endregion

    #region IOS_EVENT_LISTENER
    public void OnRatePopUpCallBack(string buttonIndex)
    {
        int index = System.Convert.ToInt16(buttonIndex);
        switch (index)
        {
            case 0: 
                IOSNative.RedirectToAppStoreRatingPage(appleId);
                RaiseOnOnRateUSPopupComplete(MessageState.RATED);
                break;
            case 1:
                RaiseOnOnRateUSPopupComplete(MessageState.REMIND);
                break;
            case 2:
                RaiseOnOnRateUSPopupComplete(MessageState.DECLINED);
                break;
        }
        Destroy(gameObject);
    }
    #endregion
}

注意
在這些類中（每個(gè)彈框的 B 部分），我們創(chuàng)建了游戲物體并且我們使用游戲物體的名字來(lái)獲得事件的回調(diào)。我們將在下一個(gè)部分（Objective-C 文件 UnitySendMessage()）使用這些名字。

第六步 設(shè)置 iOS 文件

你完成了基本的代碼！現(xiàn)在，讓我們用 Objective-C 編碼來(lái)創(chuàng)建彈框

這樣做，創(chuàng)建新的 xcode 工程來(lái)創(chuàng)建 Objective-C 文件。如果你不了解 xcdoe 并不知道怎樣使用 xcode 來(lái)創(chuàng)建工程，那么請(qǐng)看這里 使用 xcode 創(chuàng)建基本的工程。

不要擔(dān)心現(xiàn)在的代碼，你只需要在你的文件中拷貝然后粘貼。如果你在創(chuàng)建工程和文件時(shí)面臨著任何問(wèn)題，那么你可以從博客的底部下載源代碼。只要你下載完了工程，你就可以拷貝所有的 iOS 文件到你的 unity 工程的 Plugins 文件夾中

回到 xcode，創(chuàng)建新的 Objective-C 文件命名為 DataConvertor 來(lái)轉(zhuǎn)換數(shù)據(jù)。

DataConverter.h

#import <Foundation/Foundation.h>
@interface DataConvertor : NSObject
+ (NSString*) charToNSString: (char*)value;
+ (const char *) NSIntToChar: (NSInteger) value;
+ (const char *) NSStringToChar: (NSString *) value;
@end

DataConverter.m

#import "DataConvertor.h"
@implementation DataConvertor
+(NSString *) charToNSString:(char *)value {
    if (value != NULL) {
        return [NSString stringWithUTF8String: value];
    } else {
        return [NSString stringWithUTF8String: ""];
    }
}

+(const char *)NSIntToChar:(NSInteger)value {
    NSString *tmp = [NSString stringWithFormat:@"%ld", (long)value];
    return [tmp UTF8String];
}

+ (const char *)NSStringToChar:(NSString *)value {
    return [value UTF8String];
}
@end

創(chuàng)建另一個(gè)文件命名為 IOSNativePopUpsManager 來(lái)從 unity 腳本中調(diào)用，并且顯示彈框。

IOSNativePopUpsManager.h

#import <Foundation/Foundation.h>
#import "DataConvertor.h"
@interface IOSNativePopUpsManager : NSObject
+ (void) unregisterAllertView;
@end

IOSNativePopUpsManager.m

#import "IOSNativePopUpsManager.h"
@implementation IOSNativePopUpsManager
static UIAlertController* _currentAllert = nil;

+(void) dismissCurrentAlert {
    if(_currentAllert != nil) {
        [_currentAllert dismissViewControllerAnimated:NO completion:nil];
        _currentAllert = nil;
    }
}

    [alertController addAction:rateAction];
    [alertController addAction:laterAction];
    [alertController addAction:declineAction];
    [[[[UIApplication sharedApplication] keyWindow] rootViewController] presentViewController:alertController animated:YES completion:nil];
    _currentAllert = alertController;

    UIAlertController *alertController = [UIAlertController alertControllerWithTitle:title message:msg preferredStyle:UIAlertControllerStyleAlert];
    UIAlertAction *yesAction = [UIAlertAction actionWithTitle:b1 style:UIAlertActionStyleDefault handler:^(UIAlertAction * _Nonnull action) {
    [IOSNativePopUpsManager unregisterAllertView];
    UnitySendMessage("IOSDialogPopUp", "OnDialogPopUpCallBack", [DataConvertor NSIntToChar:0]);
    }];

    UIAlertAction *noAction = [UIAlertAction actionWithTitle:b2 style:UIAlertActionStyleDefault handler:^(UIAlertAction * _Nonnull action) {
    [IOSNativePopUpsManager unregisterAllertView];
    UnitySendMessage("IOSDialogPopUp", "OnDialogPopUpCallBack", [DataConvertor NSIntToChar:1]);
    }];

    [alertController addAction:yesAction];
    [alertController addAction:noAction];
    [[[[UIApplication sharedApplication] keyWindow] rootViewController] presentViewController:alertController animated:YES completion:nil];
    _currentAllert = alertController;
}

+(void)showMessage: (NSString *) title message: (NSString*) msg okTitle:(NSString*) b1 {
    UIAlertController *alertController = [UIAlertController alertControllerWithTitle:title message:msg preferredStyle:UIAlertControllerStyleAlert];
    UIAlertAction *okAction = [UIAlertAction actionWithTitle:b1 style:UIAlertActionStyleDefault handler:^(UIAlertAction * _Nonnull action) {
    [IOSNativePopUpsManager unregisterAllertView];
    UnitySendMessage("IOSMessagePopUp", "OnPopUpCallBack", [DataConvertor NSIntToChar:0]);

    [alertController addAction:okAction];
    [[[[UIApplication sharedApplication] keyWindow] rootViewController] presentViewController:alertController animated:YES completion:nil];
    _currentAllert = alertController;
}

extern "C" {
    // Unity Call
    void _TAG_ShowRateUsPopUp(char* title, char* message, char* b1, char* b2, char* b3) {
        [IOSNativePopUpsManager showRateUsPopUp:[DataConvertor charToNSString:title] message:[DataConvertor charToNSString:message] b1:[DataConvertor charToNSString:b1] b2:[DataConvertor charToNSString:b2] b3:[DataConvertor charToNSString:b3]];
    }
    void _TAG_ShowDialog(char* title, char* message, char* yes, char* no) {
        [IOSNativePopUpsManager showDialog:[DataConvertor charToNSString:title] message:[DataConvertor charToNSString:message] yesTitle:[DataConvertor charToNSString:yes] noTitle:[DataConvertor charToNSString:no]];
    }
    void _TAG_ShowMessage(char* title, char* message, char* ok) {

    }
    void _TAG_DismissCurrentAlert() {

注意
在這個(gè)類中，我們使用 UnitySendMessage() 向 unity 發(fā)送一條消息，然后我們使用游戲物體的名字作為參數(shù)。必須和創(chuàng)建的游戲物體，特別是彈框類相匹配。

現(xiàn)在創(chuàng)建一個(gè)新的文件命名為 IOSNativeUtility 來(lái)重定向控制從應(yīng)用程序到評(píng)價(jià)頁(yè)面或者任何其他網(wǎng)頁(yè)。

IOSNativeUtility.h

#import <Foundation/Foundation.h>
#import "DataConvertor.h"
#if UNITY_VERSION < 450
#include "iPhone_View.h"
#endif

@interface IOSNativeUtility : NSObject
@property (strong) UIActivityIndicatorView *spinner;
+ (id) sharedInstance;
- (void) redirectToRatigPage: (NSString *) appId;

        _sharedInstance = [[self alloc] init];

    return _sharedInstance;

現(xiàn)在，從 xcode 工程目錄中把所有的 Objective-C 文件拷貝到 unity 工程的 Plugins 目錄中。

如果你在創(chuàng)建 xcode 工程或 Objective-C 文件時(shí)面臨著任何問(wèn)題，那么你可以從博客的底部下載源代碼。只要你下載完了工程，你就可以拷貝所有的 Objective-C 文件到你的 unity 工程的 Plugins/iOS 文件夾中

我希望這篇博客對(duì)你是有幫助的。如果你對(duì) iOS 原生彈框有任何問(wèn)題或疑惑，那么請(qǐng)自由地在評(píng)論區(qū)發(fā)表評(píng)論。我一定會(huì)盡快回復(fù)你。有一個(gè)游戲開(kāi)發(fā)的想法么？你還在等什么？現(xiàn)在就聯(lián)系我們吧，不久你就會(huì)看到你的想法實(shí)現(xiàn)了。
