您可以使用一组图像并在 1 个 UIImage 中为它们制作动画:

iOS 5:

@interface UIImage (WrightsCS)
+(UIImage *)animatedImageWithImages:(NSArray *)images duration:(NSTimeInterval)duration;
@end

if ( SYSTEM_VERSION_GREATER_THAN(@"5.0") )
{
    NSArray *animationFrames = [NSArray arrayWithObjects:
                                [UIImage imageNamed:@"image_0.png"],
                                [UIImage imageNamed:@"image_1.png"],
                                [UIImage imageNamed:@"image_3.png"],
                                [UIImage imageNamed:@"image_4.png"], nil];

    UIImage * animatedImage = [UIImage animatedImageWithImages:animationFrames duration:2.0f];    
}
