推荐答案

将您喜欢的图像导入到您的捆绑应用程序
将它们称为image1.png，image2.png image3.png等....

import the images you like to your bundle application called them image1.png, image2.png image3.png and so on....

在界面构建器中添加UIImageview调用它（引用） H文件中的theImage

Add UIImageview in interface builder call it (reference) "theImage"

：

@interface delme3ViewController : UIViewController {

    UIImageView *theImage;
    int imageCount;
}
@property (nonatomic, retain) IBOutlet UIImageView *theImage;

@end

：

- (void)viewDidLoad
{
    [super viewDidLoad];
    [NSTimer scheduledTimerWithTimeInterval:1 
                                     target:self 
                                   selector:@selector(animateFunction) 
                                   userInfo:nil 
                                    repeats:YES];
    imageCount = 1;

}

-(void)animateFunction
{
    NSLog(@"Timer heartbeat %i",imageCount);
    imageCount = imageCount + 1;
    NSString *imageName = [NSString stringWithFormat:@"image%i.png"];
    [theImage setImage:[UIImage imageNamed:imageName]];
}
