ios - 检测 iOS 设备类型

Question

在我的应用程序（用 Objective-C 编写）中，我如何检测设备是 iPhone、iPad 还是 iPhone5？

if([[UIDevice currentDevice]userInterfaceIdiom] == UIUserInterfaceIdiomPhone) {
    // [iphone] or [itouch]
} else {
    // [ipad]
}

Answer 1

您可以在以下条件下轻松检测 iphone、iphone5 和 iPad（但不是 iTouch！iTouch 被视为使用此代码的 iPhone！）：-

 if([[UIDevice currentDevice]userInterfaceIdiom]==UIUserInterfaceIdiomPhone)
 {
     if ([[UIScreen mainScreen] bounds].size.height == 568)
     {


     }
     else
     {
         //iphone 3.5 inch screen
     }
 }
 else
 {
        //[ipad]
 }

更新

您还可以使用 MACRO 或定义变量来检查 iPhone5、iPhone4 或 iPad，如 Bellow：-

#define isiPhone5  ([[UIScreen mainScreen] bounds].size.height == 568)?TRUE:FALSE
#define isiPhone  (UI_USER_INTERFACE_IDIOM() == 0)?TRUE:FALSE

例子：-

if(isiPhone)
     {
         if (isiPhone5)
         {


         }
         else
         {
             //iphone 3.5 inch screen
         }
     }
     else
     {
            //[ipad]
     }

希望这对你有用...

Answer 3

if ([[UIDevice currentDevice].model hasPrefix:@"iPhone"]) {//iPhone... (not iTouch or iPad)

if ([[UIDevice currentDevice].model hasPrefix:@"iPad"]) {//iPad...

if (([[UIDevice currentDevice].model hasPrefix:@"iPhone"]) && ([UIScreen mainScreen]bounds].size.height == 568)) {//iPhone5...

而且，仅供参考... iTouch 是这样的：

if ([[UIDevice currentDevice].model hasPrefix:@"iPod"]) {//iTouch

Answer 4

- (id)initWithNibName:(NSString *)nibName bundle:(NSBundle *)nibBundle {
if ([[ UIScreen mainScreen ] bounds ].size.height == 568 ) {
nibName = [NSString stringWithFormat:@"%@_568", nibName];

}

if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad) {
nibName = [NSString stringWithFormat:@"%@_iPad", nibName]; {

}

if (self = [super initWithNibName:nibName bundle:nibBundle]) {
}

return self;
}

第一条语句检查您拥有的设备是否有 iPhone 5 屏幕。

第二个检查您使用 iPad 的天气。

第三个返回 iPhone 4s 和之前的正常 xib。

请注意，要完成这项工作，您必须创建 3 个不同的 XIB，它们都具有不同的后缀。

视图控制器.xib

ViewController_568.xib

ViewController_iPad.xib

Answer 5

这里有一堆常量，您可以粘贴在 PCH 文件中并在整个应用程序中使用，它们为您提供了许多可以测试的不同内容。（这里的宽屏是指 iPhone 5 “更高”的屏幕）

#ifndef IS_WIDESCREEN
#define IS_WIDESCREEN   (fabs((double)[[UIScreen mainScreen] bounds].size.height - (double)568) < DBL_EPSILON)
#endif

#ifndef IS_IPHONE
#define IS_IPHONE       ([[[UIDevice currentDevice] model] isEqualToString:@"iPhone"])
#endif

#ifndef IS_IPOD
#define IS_IPOD         ([[[UIDevice currentDevice] model] isEqualToString:@"iPod touch"])
#endif

#ifndef IS_IPAD
#define IS_IPAD         ([[[UIDevice currentDevice] model] isEqualToString:@"iPad"])
#endif

#ifndef IS_IPHONE5
#define IS_IPHONE5      (IS_WIDESCREEN && IS_IPHONE)
#endif

#ifndef IS_IPOD5
#define IS_IPOD5        (IS_WIDESCREEN && IS_IPOD)
#endif

你可以像这样使用它：

if(IS_IPHONE5){
    // load iPhone5 code/nibs
}

if(IS_WIDESCREEN){
    // load 4" screen stuff here
}
