我有一些UIButtons,我想在屏幕中间按下其他不相关的东西时触发短5-10帧动画。我可以在IB中删除一个UIImageView并以某种方式以编程方式更新它吗?它不需要过于复杂,我甚至不介意它是否是硬编码的,因为它是一个如此小的项目。
感谢。

以下是使用几帧进行动画最简单方法的示例:
声明IBOutlet UIImageView *timerAnimation
并将其链接到IB中的UIIMageView。向您的资源添加一些图像,例如下面需要的。然后将图像加载到数组中 - 请参阅代码:
timerAnimation.animationImages = [NSArray arrayWithObjects:
[UIImage imageNamed:@"timer00.png"],
[UIImage imageNamed:@"timer01.png"],
[UIImage imageNamed:@"timer02.png"],
[UIImage imageNamed:@"timer03.png"],
[UIImage imageNamed:@"timer04.png"],
[UIImage imageNamed:@"timer05.png"],
[UIImage imageNamed:@"timer06.png"],
[UIImage imageNamed:@"timer07.png"],
[UIImage imageNamed:@"timer08.png"],
[UIImage imageNamed:@"timer09.png"],
[UIImage imageNamed:@"timer10.png"],
[UIImage imageNamed:@"timer11.png"],
[UIImage imageNamed:@"timer12.png"],
[UIImage imageNamed:@"timer13.png"],
[UIImage imageNamed:@"timer14.png"],
[UIImage imageNamed:@"timer15.png"],
[UIImage imageNamed:@"timer16.png"],
[UIImage imageNamed:@"timer17.png"],
[UIImage imageNamed:@"timer18.png"],
[UIImage imageNamed:@"timer19.png"],
[UIImage imageNamed:@"timer20.png"],
[UIImage imageNamed:@"timer21.png"],
[UIImage imageNamed:@"timer22.png"],
[UIImage imageNamed:@"timer23.png"],
[UIImage imageNamed:@"timer24.png"],
[UIImage imageNamed:@"timer25.png"],
[UIImage imageNamed:@"timer26.png"],
[UIImage imageNamed:@"timer27.png"],
[UIImage imageNamed:@"timer28.png"],
[UIImage imageNamed:@"timer29.png"],
[UIImage imageNamed:@"timer30.png"],
[UIImage imageNamed:@"timer31.png"],
[UIImage imageNamed:@"timer32.png"],
[UIImage imageNamed:@"timer33.png"],
[UIImage imageNamed:@"timer34.png"],
[UIImage imageNamed:@"timer35.png"],
// [UIImage imageNamed:@"timer36.png"], save last picture for "times up"
nil];
timerAnimation.animationDuration = 5.0;
timerAnimation.animationRepeatCount = 1;
[timerAnimation startAnimating];
这将运行您的动画,直到您致电[timerAnimation stopAnimating];
