我有三个图像和一个图像视图，我希望逐个显示每个图像，并在3秒后在imageview中重复。任何人都可以给我一些建议或链接吗？提前致谢

Answer 1

您可以使用NStimer方法在一段时间后控制更改。尝试着它。

Answer 2

您可以使用UIImageView的动画功能来实现此目的。

 // create the view that will execute our animation
 UIImageView *campFireView = [[UIImageView alloc] initWithFrame:self.view.frame];

 // load all the frames of our animation
 campFireView.animationImages = [NSArray arrayWithObjects:   
                             [UIImage imageNamed:@"yourImage01.png"],
                             [UIImage imageNamed:@"yourImage02.png"],
                             [UIImage imageNamed:@"yourImage03.png"],
                             nil];

 // all frames will execute in 3 seconds
 campFireView.animationDuration = 3;
 // repeat the annimation forever
 campFireView.animationRepeatCount = 0;
 // start animating
 [campFireView startAnimating];
 //Add imageView to view
 [self.view addSubview:campFireView];
