iOS开发判断各个设备型号（放大模式和标准模式）

//#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 &&  ([[ UIScreen mainScreen ] bounds ]. size . height ==  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 &&  [[ UIScreen mainScreen ] bounds ]. size . height ==  667.0   && IS_OS_8_OR_LATER &&  [ UIScreen mainScreen ]. nativeScale ==  [ UIScreen mainScreen ]. scale )
//#define IS_ZOOMED_IPHONE_6 ( IS_IPHONE &&  [[ UIScreen mainScreen ] bounds ]. size . height ==  568.0  && IS_OS_8_OR_LATER &&  [ UIScreen mainScreen ]. nativeScale >  [ UIScreen mainScreen ]. scale )
//#define IS_STANDARD_IPHONE_6_PLUS ( IS_IPHONE &&  [[ UIScreen mainScreen ] bounds ]. size . height ==  736.0 )
//#define IS_ZOOMED_IPHONE_6_PLUS ( IS_IPHONE &&  [[ UIScreen mainScreen ] bounds ]. size . height ==  667.0  && IS_OS_8_OR_LATER &&  [ UIScreen mainScreen ]. nativeScale <  [ UIScreen mainScreen ]. scale )
