iOS 6背景图像

Question

我有一个全屏幕渐变背景的iOs应用程序。现在，与iPhone 5的屏幕大小是不同的，当然我想支持第5和第4设备。

推荐的方法是什么？

Answer 1

从我挂在注释后

#import <sys/utsname.h> 

NSString* 
machineName() 
{ 
struct utsname systemInfo; 
uname(&systemInfo); 

return [NSString stringWithCString:systemInfo.machine 
          encoding:NSUTF8StringEncoding]; 
} 

结果应该是：

@"i386"  on the simulator 
@"iPod1,1" on iPod Touch 
@"iPod2,1" on iPod Touch Second Generation 
@"iPod3,1" on iPod Touch Third Generation 
@"iPod4,1" on iPod Touch Fourth Generation 
@"iPhone1,1" on iPhone 
@"iPhone1,2" on iPhone 3G 
@"iPhone2,1" on iPhone 3GS 
@"iPad1,1" on iPad 
@"iPad2,1" on iPad 2 
@"iPhone3,1" on iPhone 4 
@"iPhone4,1" on iPhone 4S 

我假定这将返回类似@“iPhone5,1”最新模型。然后，只需做这样

NSString *iphoneType = machineName(); 
if ([iphoneType isEqualToString@"iPhone5,1"]){ 
    //image for iphone 5 
} else { 
      //image for the rest 
} 

支票让我知道，如果可以算出
