在IOS3.2及以后的版本中, 可以使用UIKit中定义的函数UI_USER_INTERFACE_IDIOM来判断, 该函数返回两个值为UIUserInterfaceIdiomPhone和UIUserInterfaceIdiomPad.

为方便可在代码中定义isiPad来直接判断

#define isiPad (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad)

 

 

UI_USER_INTERFACE_IDIOM

Returns the interface idiom supported by the current device.

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

 

Return Value

UIUserInterfaceIdiomPhone if the device is an iPhone or iPod touch or UIUserInterfaceIdiomPad if the device is an iPad.

Availability

Available in iOS 3.2 and later.
