我有几个UIButtons,我希望在屏幕中间按下时触发短暂的5-10帧动画,以及其他无关的东西。我能不能只在IB中放一个UIImageView并通过编程方式更新它呢?它不需要过于复杂,现在即使是硬编码也没关系,因为这是一个很小的项目。
谢谢。
谢谢。
IBOutlet UIImageView *timerAnimation
并将其链接到IB中的UIImageView。将一些图像添加到您的资源中,例如下面所需的内容。然后将这些图像加载到数组中 - 请参见以下代码: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,直至您调用[timerAnimation stopAnimating];
