在编译iPad时是否有一个特定的Xcode编译器标志？

问题描述

是否有特定的Xcode编译器标志在编译iPad时设置？

Is there a specific Xcode compiler flag that gets set when compiling for iPad?

我想有条件地编译iPad与iPhone / iPod Touch代码，例如：

I want to conditionally compile iPad vs iPhone/iPod Touch code for example:

#ifdef TARGET_IPAD
   code for iPad
#else
   code for iPhone
#endif

我知道TargetConditionals.h中已经有TARGET_OS_IPHONE和TARGET_CPU_ARM但是任何容易且专门针对iPad的东西？

I know there is already TARGET_OS_IPHONE and TARGET_CPU_ARM in TargetConditionals.h but anything that easily and specifically targets iPad?

推荐答案

用于运行的正确API iPad与iPhone / iPad Touch的时间检查是：

The correct API to use for run-time checking of iPad vs. iPhone/iPad Touch is:

BOOL deviceIsPad = ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPad);

UIDevice头文件管理器还包括一个方便的宏UI_USER_INTERFACE_IDIOM（），如果你的部署有用目标是< iPhone 3.2。

The UIDevice header filer also includes a convenient macro, UI_USER_INTERFACE_IDIOM(), which will be helpful if your deployment target is < iPhone 3.2.

#define UI_USER_INTERFACE_IDIOM() ([[UIDevice currentDevice] respondsToSelector:@selector(userInterfaceIdiom)] ? [[UIDevice currentDevice] userInterfaceIdiom] : UIUserInterfaceIdiomPhone)

所以你可以说是消极的：

So you could just say, negatively:

BOOL deviceIsPad = (UI_USER_INTERFACE_IDIOM() != UIUserInterfaceIdiomPhone);
