獲取iOS設(shè)備UI類型和設(shè)備名稱

在開(kāi)發(fā)過(guò)程中有時(shí)需要獲取設(shè)備具體型號(hào)然后進(jìn)行不同的適配。

目前我們的在適配iOS設(shè)備主要分為UI方面的適配，比如iPhone5 、iPhone6、iPhone6 Plus、iPhoneX、iPhoneXS Max，具體的UI在這些屏幕的適配上都是不一樣的。
部分APP還適配了iPad，適配iPad與iPhone 的UI 又不一樣。

目前還有一部分的設(shè)備是需要獲取具體的設(shè)備名稱，比如我們通過(guò)代碼獲取設(shè)備的名稱iPhone6,1，但對(duì)應(yīng)的我們經(jīng)常口頭說(shuō)的設(shè)備卻并不是iPhone6，其實(shí)質(zhì)對(duì)應(yīng)的是我們最經(jīng)典的iPhone5。

那么我們?nèi)绾螌?duì)應(yīng)這些需求呢？

設(shè)備屏幕類型

我們一般通過(guò)宏的定義來(lái)區(qū)分具體的iPhone和iPad設(shè)備類型UI。

首先是我們?nèi)绾螀^(qū)分iPad和iPhone設(shè)備。
// iPhone 設(shè)備
#define kUI_IPHONE             ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPhone)
// iPad 設(shè)備
#define kUI_IPAD               ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPad)

具體可以參考代碼中的枚舉值

typedef NS_ENUM(NSInteger, UIUserInterfaceIdiom) {
    UIUserInterfaceIdiomUnspecified = -1,
    UIUserInterfaceIdiomPhone NS_ENUM_AVAILABLE_IOS(3_2), // iPhone and iPod touch style UI
    UIUserInterfaceIdiomPad NS_ENUM_AVAILABLE_IOS(3_2), // iPad style UI
    UIUserInterfaceIdiomTV NS_ENUM_AVAILABLE_IOS(9_0), // Apple TV style UI
    UIUserInterfaceIdiomCarPlay NS_ENUM_AVAILABLE_IOS(9_0), // CarPlay style UI
};

一般情況下iPad設(shè)備一套UI 基本能夠適配所有的iPad設(shè)備的UI類型，因?yàn)镸ini系列 Air系列包括目前的新款全面屏其寬高比基本都是一致的。很少的情況去做特殊的UI適配。

首先是我們?nèi)绾螀^(qū)分iPhone設(shè)備不同的UI類型。
// iPhone4 和4s系列
#define kUI_IPHONE4            ([UIScreen instancesRespondToSelector:@selector(currentMode)] ? CGSizeEqualToSize(CGSizeMake(640, 960), [[UIScreen mainScreen] currentMode].size) && kUI_IPHONE : NO)

// iPhone5 和5s系列
#define kUI_IPHONE5            ([UIScreen instancesRespondToSelector:@selector(currentMode)] ? CGSizeEqualToSize(CGSizeMake(640, 1136), [[UIScreen mainScreen] currentMode].size) && kUI_IPHONE : NO)

// iPhone6 和6s系列（包括6，7，8三代產(chǎn)品）
#define kUI_IPHONE6            ([UIScreen instancesRespondToSelector:@selector(currentMode)] ? CGSizeEqualToSize(CGSizeMake(750, 1334), [[UIScreen mainScreen] currentMode].size) && kUI_IPHONE : NO)

// iPhone6 Plus 和6s Plus系列（包括6，7，8三代產(chǎn)品）
#define kUI_IPHONE6PLUS        ([UIScreen instancesRespondToSelector:@selector(currentMode)] ? CGSizeEqualToSize(CGSizeMake(1242, 2208), [[UIScreen mainScreen] currentMode].size) && kUI_IPHONE : NO)

//判斷iPHoneXr   (CGSizeMake(828, 1792) 啟動(dòng)圖   CGSizeMake(750, 1624) 無(wú)啟動(dòng)圖
#define kUI_IPhoneXR ([UIScreen instancesRespondToSelector:@selector(currentMode)] ? (CGSizeEqualToSize(CGSizeMake(828, 1792), [[UIScreen mainScreen] currentMode].size)|| CGSizeEqualToSize(CGSizeMake(750, 1624), [[UIScreen mainScreen] currentMode].size))&& kUI_IPHONE : NO)

//判斷iPhoneXs 和iPhoneX
#define kUI_IPhoneXS ([UIScreen instancesRespondToSelector:@selector(currentMode)] ? CGSizeEqualToSize(CGSizeMake(1125, 2436), [[UIScreen mainScreen] currentMode].size) && kUI_IPHONE : NO)

//判斷iPhoneXs Max
#define kUI_IPhoneXSMAX ([UIScreen instancesRespondToSelector:@selector(currentMode)] ? CGSizeEqualToSize(CGSizeMake(1242, 2688), [[UIScreen mainScreen] currentMode].size) && kUI_IPHONE : NO)

//判斷是否是X全系列 留海屏幕
#define kUI_IPhoneX            (kUI_IPhoneXR ||kUI_IPhoneXS ||kUI_IPhoneXSMAX)

目前主要是iPhoneX系NaviBar 、 Tabbar 和StatusBar 的高度與其他系列都不一樣，所以一般情況下還是有高度也有不一樣

//iPhoneX系列
#define kStatusBarHeight  (kUI_IPhoneX ? 44.0 : 20.0)
#define kNaviBarHeight      (kUI_IPhoneX ? 88.0 : 64.0)
#define kTabBarHeight      (kUI_IPhoneX ? 83.0 : 49.0)

獲取設(shè)備類型名稱

我們通過(guò)代碼獲取的設(shè)備硬件編碼字符串是"iPhone6,1"，其實(shí)這里面有三個(gè)參數(shù)， 每個(gè)參數(shù)都是有具體的含義的。

1、iPhone 代表的是具體的設(shè)備類型，比如iPhone代表手機(jī)，iPad代表平板
2、6 代表的是具體的設(shè)備版本，其中6對(duì)應(yīng)的是iPhone手機(jī)5代產(chǎn)品，即我們常說(shuō)的iPhone 5
3、1 代表銷售地區(qū)和網(wǎng)絡(luò)型號(hào)，例如"iPhone6,1"中的1表示只在美國(guó)、加拿大、墨西哥等地區(qū)銷售的LTE 網(wǎng)絡(luò)類型設(shè)備，其中2表示其他國(guó)家銷售的蘋(píng)果設(shè)備，但是也一樣在美國(guó)和加拿大地區(qū)銷售。
