因此在iOS I 上的视网膜显示通常有图像, 其大小为@ 2x/ per apple 指南的两倍 。 如何进行视网膜显示。 但这个命名公约只对程序捆绑中的图像起作用, 而这些图像是我无法写入的 。

设置视网膜图像
UIImage *image; // from download
image=[UIImage imageWithCGImage:[image CGImage] scale:2.0 orientation:UIImageOrientationUp];
如果您有一个视网膜显示, 请先检查
if([[UIScreen mainScreen] respondsToSelector:@selector(scale)])
BOOL retina = [[UIScreen mainScreen] scale] == 2.0 ? YES : NO;
如果"retine =YYYY", 获取您想要的视网膜图像
