UIDevice_iPadHiRes : UIDevice_iPadStandardRes);}@end

方法二：使用宏定义方式判断是否为iphone5

#define iPhone5 ([UIScreen instancesRespondToSelector:@selector(currentMode)] ? CGSizeEqualToSize(CGSizeMake(640,1136),[[UIScreen mainScreen] currentMode].size) : NO)

if (!iPhone5) {        [[NSBundle mainBundle]loadNibnamed:@"xxxController" owner:self options:nil];      }else {        [[NSBundle mainBundle]loadNibnamed:@"xxxController4inch" owner:self options:nil];    }
