根据屏幕尺寸判断各机型尺寸

#define IS_IPHONE (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPhone)  


    #define __kScreenHeight ([[UIScreen mainScreen]bounds].size.height)
    #define __kScreenWidth ([[UIScreen mainScreen]bounds].size.width)  
    #define SCREEN_MAX_LENGTH (MAX(__kScreenWidth, __kScreenHeight))
    #define SCREEN_MIN_LENGTH (MIN(__kScreenWidth, __kScreenHeight)) 

    #define IS_IPHONE_4_OR_LESS (IS_IPHONE && SCREEN_MAX_LENGTH < 568.0)  
    #define IS_IPHONE_5 (IS_IPHONE && SCREEN_MAX_LENGTH == 568.0)  
    #define IS_IPHONE_6_7 (IS_IPHONE && SCREEN_MAX_LENGTH == 667.0)  
    #define IS_IPHONE_6P_7P (IS_IPHONE && SCREEN_MAX_LENGTH == 736.0)
