微信原生的分享（轉(zhuǎn)載）

轉(zhuǎn)載自 http://www.cnblogs.com/mancong/p/5807924.html

一.微信原生的分享--準(zhǔn)備工作.

  1. 需要申請(qǐng)微信AppId.

  1. 導(dǎo)入系統(tǒng)架包.
    SDK文件包括 libWeChatSDK.a，WXApi.h，WXApiObject.h,WechatAuthSDK.四個(gè).
    3.導(dǎo)入必要的系統(tǒng)庫.
    SystemConfiguration.framework,
    libz.dylib,
    libsqlite3.0.dylib,
    libc++.dylib,
    CoreTelephoy.framework (坑一: 這個(gè)庫是必要的,但是微信官方文檔中沒有說到要導(dǎo)入)

  2. 該項(xiàng)目中的Bundle Identifier 應(yīng)該填向微信注冊(cè)的Bundle Identifier

  3. 注冊(cè)微信 (回調(diào)的時(shí)候用到,告訴微信,從微信返回到哪個(gè)APP)
    Target --> info --> URL Types --> +按鈕 --> 填寫identifier 和 URL Schemes. 前一個(gè)是標(biāo)識(shí)符,一般填@"weixin".后一個(gè)是注冊(cè)的微信appId. 比如"wx19a984b788a8a0b1".(注釋: 假的appid)

  4. 添加微信白名單
    info.plist --> 右擊 --> open as --> source Code --> 添加白名單
    我是在<key>CFBundleVersion</key>這一行上面添加的. 注意保持正確的鍵值對(duì).別插錯(cuò)了.

 <key>LSApplicationQueriesSchemes</key>
 <array>
  <string>wechat</string>
  <string>weixin</string>
 </array>

二. 代碼部分.

AppDelegate.h中
(1) 導(dǎo)入

import "WXApi.h"

(2) 遵守協(xié)議
WXApiDelegate

  1. WXApiDelegate.m中
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    // Override point for customization after application launch.
    
    // 注冊(cè)微信
    [WXApi registerApp:@"wxbbf0646591e4a6d0" withDescription:@"測(cè)試"];
    return YES;
}

//被廢棄的方法. 但是在低版本中會(huì)用到.建議寫上
- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation
{
    return [WXApi handleOpenURL:url delegate:self];
}
//被廢棄的方法. 但是在低版本中會(huì)用到.建議寫上

- (BOOL)application:(UIApplication *)application handleOpenURL:(NSURL *)url
{
    return [WXApi handleOpenURL:url delegate:self];
}

//新的方法
- (BOOL)application:(UIApplication *)app openURL:(NSURL *)url options:(NSDictionary<NSString *,id> *)options
{
    return [WXApi handleOpenURL:url delegate:self];
}

// 接收分享回調(diào)通知
    //監(jiān)聽通知
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(getOrderPayResult:) name:@"WXShare" object:nil];
    [self basicSetting];
    
    // AppID：wxbbf0646591e4a6d0
