iphone - UIButton 类似闪烁

Question

你好 friend 如何使 uibutton 像眨眼一样我使用了下面的代码，但它不像眨眼在我的应用程序中，我开发了录音功能，所以我想喜欢那个按钮

CABasicAnimation *pulseAnimation = [CABasicAnimation animationWithKeyPath:@"transform.rotation"];
pulseAnimation.duration = .5;
pulseAnimation.toValue = [NSNumber numberWithFloat:1.1];
pulseAnimation.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut];
pulseAnimation.autoreverses = YES;
pulseAnimation.repeatCount = FLT_MAX;
[btnBlink.layer addAnimation:pulseAnimation forKey:nil];

Answer 1

或者您可以通过调用定义的方法使用 NSTimeInterval 连续增加或减少按钮 alpha
