iphone - 如何自定义 UIAlert View..？

Question

我通过添加图像自定义了 UIViews，使其看起来像单选按钮或复选框，但对于我的规范，我想让 UIAlertView 看起来像这样。 ..

任何人都可以建议如何做到这一点？谢谢!

您可以设计自定义 View ，并可以使用此代码为其提供动画作为警报 View

    -(void)initialDelayEnded 
{

    alert_upload.transform = CGAffineTransformScale(CGAffineTransformIdentity, 0.001, 0.001);
    alert_upload.alpha = 1.0;
    [UIView beginAnimations:nil context:nil];
    [UIView setAnimationDuration:1/1.5];
    [UIView setAnimationDelegate:self];
    [UIView setAnimationDidStopSelector:@selector(bounce1AnimationStopped)];
    alert_upload.transform = CGAffineTransformScale(CGAffineTransformIdentity, 1.1, 1.1);
    [UIView commitAnimations];
}

- (void)bounce1AnimationStopped {
    [UIView beginAnimations:nil context:nil];
    [UIView setAnimationDuration:1.5/2];
    [UIView setAnimationDelegate:self];
    [UIView setAnimationDidStopSelector:@selector(bounce2AnimationStopped)];
    alert_upload.transform = CGAffineTransformScale(CGAffineTransformIdentity, 0.9, 0.9);
    [UIView commitAnimations];
}

- (void)bounce2AnimationStopped {
    [UIView beginAnimations:nil context:nil];
    [UIView setAnimationDuration:1.5/2];
    alert_upload.transform = CGAffineTransformIdentity;
    [UIView commitAnimations];


}

alert_upload 是 UIView。
