ios - 非阻塞 UIView 动画缩放

Question

我想以非阻塞方式对 UIView 及其所有内容进行动画缩放。目前我正在这样做...

    [UIView beginAnimations:nil context:NULL];
    [UIView setAnimationDuration:0.1];
    [UIView setAnimationDelegate:self];
    [UIView setAnimationCurve:UIViewAnimationCurveEaseInOut];
            CGAffineTransform transform = CGAffineTransformMakeScale(1.1,1.1);
            self.view.transform = transform;
    [UIView commitAnimations];

但是它阻塞。我宁愿使用类似...

[UIView animateWithDuration:0.2
                     animations:^{
                CGAffineTransform transform = CGAffineTransformMakeScale(1.1,1.1);
                self.view.transform = transform;
                     }];

...但 animateWithDuration 不适用于 CALayer/CGAffineTransform 转换。如何在不阻塞任何内容的情况下实现相同的动画？

Answer 1

尝试使用:

[UIView animateWithDuration:0.2
 animations:^{
   CGAffineTransform transform =
     CGAffineTransformScale(CGAffineTransformIdentity, 2.0, 2.0);
 self.view.transform = transform;
 }];

只需为这个出色的答案添加一个有用的注释，几乎总是您想要打开光栅化，因此它看起来很流畅

self.view.layer.shouldRasterize = YES;
[UIView animateWithDuration:0.2
 animations:^{
   CGAffineTransform transform =
     CGAffineTransformScale(CGAffineTransformIdentity, 0.5, 0.5);
 self.view.transform = transform;
 }];
