IOS 的动画放大与缩小，并非按照找它的中心点放大和缩小，而是左上角 。我分析了下原来是Autolayout
与View Transforms的冲突造成的。
- (void) addSubviewWithZoomInAnimation:(UIView*)view duration:(float)secs option:(UIViewAnimationOptions)option
{
// first reduce the view to 1/100th of its original dimension
CGAffineTransform trans = CGAffineTransformScale(view.transform, 0.01, 0.01);
view.transform = trans; // do it instantly, no animation
[self addSubview:view];
// now return the view to normal dimension, animating this tranformation
[UIView animateWithDuration:secs delay:0.0 options:option
animations:^{
view.transform = CGAffineTransformScale(view.transform, 100.0, 100.0);
}
completion:nil];
}- (void) removeWithZoomOutAnimation:(float)secs option:(UIViewAnimationOptions)option
{
[UIView animateWithDuration:secs delay:0.0 options:option
animations:^{
self.transform = CGAffineTransformScale(self.transform, 0.01, 0.01);
}
completion:^(BOOL finished) {
[self removeFromSuperview];
}];
}
解决方案：
Disable auto
layout:
self.imageView.translatesAutoresizingMaskIntoConstraints
= YES;
