如何在标准或缩放模式下检测用户是否拥有iPhone 6 Plus？

如何在标准或缩放模式下检测用户是否拥有iPhone 6 Plus？ 这可能吗？

我试过[UIScreen mainScreen].scale ，它在两种情况下报告3.0 。

Answer 1

下面的代码可以用来获取bounds ， coordinateSpace ， nativeScale和scale ，即在iPhone 6 Plus上nativeScale是nativeScale ，当设备在缩放模式下运行时，它是2.88（注意在模拟器中它是不同的）：

 UIScreen *mainScreen = [UIScreen mainScreen]; NSLog(@"Screen bounds: %@, Screen resolution: %@, scale: %f, nativeScale: %f", NSStringFromCGRect(mainScreen.bounds), mainScreen.coordinateSpace, mainScreen.scale, mainScreen.nativeScale); 

检测iPhone 6 Plus的代码：

 -(BOOL)iPhone6PlusDevice{ // Scale is 3 currently only for iPhone 6 Plus if ([UIScreen mainScreen].scale > 2.9) return YES; return NO; } 

要么

  -(BOOL)iPhone6PlusUnZoomed{ if ([self iPhone6PlusDevice]){ if ([UIScreen mainScreen].bounds.size.height > 720.0) return YES; // Height is 736, but 667 when zoomed. } return NO; } 

注意：如果您正在检查iPhone 6 Plus，要调整用户界面，则不要依靠.nativeScale ，因为模拟器和实际设备会给出不同的结果。

[UIScreen mainScreen].currentMode报告：

 <UIScreenMode: 0x17802f240; size = 1242.000000 x 2208.000000> // STANDARD <UIScreenMode: 0x178226be0; size = 1125.000000 x 2001.000000> // ZOOMED 

Answer 3

有一个新成员

 [[UIScreen mainScreen] nativeScale] 

哪个应该做你想要的。 它只在iOS 8上可用，所以你需要保护它

Answer 4

这些选项用于检测iPhone设备。

 #define IS_IPAD (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad) #define IS_IPHONE (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPhone) #define IS_IPHONE_5 (IS_IPHONE && [[UIScreen mainScreen] bounds].size.height == 568.0) #define IS_IPHONE_6 (IS_IPHONE && [[UIScreen mainScreen] bounds].size.height == 667.0) #define IS_IPHONE_6PLUS (IS_IPHONE && [[UIScreen mainScreen] nativeScale] == 3.0f) #define IS_IPHONE_6_PLUS (IS_IPHONE && [[UIScreen mainScreen] bounds].size.height == 736.0) #define IS_RETINA ([[UIScreen mainScreen] scale] == 2.0)

PaulaChavarría对iOS 8的回答 （其中[UIScreen mainScreen].bounds.size取决于方向）的更新macros：

 #define IS_OS_8_OR_LATER ([[[UIDevice currentDevice] systemVersion] floatValue] >= 8.0) #define IS_IPAD (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad) #define IS_IPHONE (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPhone) #define IS_IPHONE_5 (IS_IPHONE && (MAX([[UIScreen mainScreen] bounds].size.height, [[UIScreen mainScreen] bounds].size.width) == 568.0) && ((IS_OS_8_OR_LATER && [UIScreen mainScreen].nativeScale == [UIScreen mainScreen].scale) || !IS_OS_8_OR_LATER)) #define IS_STANDARD_IPHONE_6 (IS_IPHONE && MAX([[UIScreen mainScreen] bounds].size.height, [[UIScreen mainScreen] bounds].size.width) == 667.0 && IS_OS_8_OR_LATER && [UIScreen mainScreen].nativeScale == [UIScreen mainScreen].scale) #define IS_ZOOMED_IPHONE_6 (IS_IPHONE && MAX([[UIScreen mainScreen] bounds].size.height, [[UIScreen mainScreen] bounds].size.width) == 568.0 && IS_OS_8_OR_LATER && [UIScreen mainScreen].nativeScale > [UIScreen mainScreen].scale) #define IS_STANDARD_IPHONE_6_PLUS (IS_IPHONE && MAX([[UIScreen mainScreen] bounds].size.height, [[UIScreen mainScreen] bounds].size.width) == 736.0) #define IS_ZOOMED_IPHONE_6_PLUS (IS_IPHONE && MAX([[UIScreen mainScreen] bounds].size.height, [[UIScreen mainScreen] bounds].size.width) == 667.0 && IS_OS_8_OR_LATER && [UIScreen mainScreen].nativeScale < [UIScreen mainScreen].scale) #define IS_IPHONE_6 (IS_STANDARD_IPHONE_6 || IS_ZOOMED_IPHONE_6) #define IS_IPHONE_6_PLUS (IS_STANDARD_IPHONE_6_PLUS || IS_ZOOMED_IPHONE_6_PLUS)
