iOS 获取屏幕分辨率 以及放大模式、高清模式区别无标题文章

CGRect rect_screen = [[UIScreenmainScreen]bounds];

CGSize size_screen = rect_screen.size;

CGFloat scale_screen = [UIScreenmainScreen].scale;

CGFloat width = size_screen.width*scale_screen;

CGFloat height = size_screen.height*scale_screen;

NSLog(@"width:%f",width);

NSLog(@"height:%f",height);

上述情况在iphone6和iPhone6 Plus的缩放模式下，和iPhone5S获取到的分辨率是一样的。

别忘记iphone 6 6+有放大模式和，正常模式

#define iPhone5 ([UIScreen

instancesRespondToSelector:@selector(currentMode)] ?

CGSizeEqualToSize(CGSizeMake(640, 1136), [[UIScreen mainScreen]

currentMode].size) : NO)

//放大版的iphone6等于Iphone5的分辨率《求区别办法》

#define iPhone6 ([UIScreen

instancesRespondToSelector:@selector(currentMode)] ?

(CGSizeEqualToSize(CGSizeMake(750, 1334), [[UIScreen mainScreen]

currentMode].size) || CGSizeEqualToSize(CGSizeMake(640, 1136),

[[UIScreen mainScreen] currentMode].size)) : NO)

#define iPhone6plus ([UIScreen

instancesRespondToSelector:@selector(currentMode)] ?

(CGSizeEqualToSize(CGSizeMake(1125, 2001), [[UIScreen mainScreen]

currentMode].size) || CGSizeEqualToSize(CGSizeMake(1242, 2208),

[[UIScreen mainScreen] currentMode].size))

: NO)
