Iphone 闪烁隐藏和使用块

我的方法是：

- (void)blinkView:(UIView *)view
{
    view.layer.opacity = 0.0f;
    view.hidden = NO;

    [UIView beginAnimations:@"Blinking" context:nil];
    [UIView setAnimationRepeatCount:1.0];
    [UIView setAnimationDuration:0.6f];
    [UIView setAnimationCurve:UIViewAnimationCurveEaseInOut];
    view.layer.opacity = 1.0f;
    [UIView commitAnimations];
}

如何使用块编写此代码，以及如何实现具有相反效果的方法（使用闪烁隐藏uiview）

或

可以通过递归调用动画块来设置重复计数（请参见）

希望它能帮助你

您可以使用UIView的setAnimationDelegate:和setAnimationDidStopSelector:

[UIView beginAnimations:@"Blinking" context:nil];
[UIView setAnimationRepeatCount:1.0];
[UIView setAnimationDuration:0.6f];
[UIView setAnimationDelegate:self];
[UIView setAnimationDidStopSelector:@selector(animationDidStop:finished:context:)];
[UIView setAnimationCurve:UIViewAnimationCurveEaseInOut];
view.layer.opacity = 1.0f;
[UIView commitAnimations];


- (void) animationDidStop:(NSString *)animationID finished:(NSNumber *)finished context:(void *)context {
    // add your final code here : you can give new animation effect here.
}

或者尝试使用持续时间设置动画（仅适用于iOS 4或更高版本）
