How to support custom graphics in iPhone 5, 4 inches display.
I know that for Default it's need to add -568h prefix and it's work when my status bar is hidden and my background image size is 640 x 1136 px. But when I need to add custom background for the screen that size smaller then 1136 px it doesn't work.
So how to support custom graphics in new retina display?
回答1:
You can use my three #defines:
#define isPhone568 ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPhone && [UIScreen mainScreen].bounds.size.height == 568)
#define iPhone568ImageNamed(image) (isPhone568 ? [NSString stringWithFormat:@"%@-568h", image] : image)
#define iPhone568Image(image) ([UIImage imageNamed:iPhone568ImageNamed(image)])
Just give your images the -568h@2x.png notation, and use iPhone568ImageNamed to get a name for standard name or iPhone 5/new iPod.
