iOS变换和帧动画
提问于 2019-08-22 16:53:16
我想将视图帧更改为全屏边界，并转换为风景。
我使用了UIView动画，改变帧和视图的变换。
- (void)enterFullScreen {
CGRect frame = CGRectMake(0, 0, CGRectGetHeight(UIScreen.mainScreen.bounds), CGRectGetWidth(UIScreen.mainScreen.bounds));
self.originFrame = self.presentView.frame;
[UIView animateWithDuration:ZXYAnimationDuration animations:^{
self.presentView.transform = CGAffineTransformMakeRotation(M_PI_2);
self.presentView.frame = frame;
} completion:^(BOOL finished) {
}];
}
- (void)exitFullScreen {
[UIView animateWithDuration:ZXYAnimationDuration animations:^{
self.presentView.transform = CGAffineTransformIdentity;
self.presentView.frame = self.originFrame;
} completion:^(BOOL finished) {
}];
}我希望视图旋转到横向和全屏，但似乎旋转错误。

最后，我试了一下，答案是，不要交换宽度和高度，就像下面这样：
- (void)enterFullScreen {
CGRect frame = CGRectMake(0, 0, CGRectGetWidth(UIScreen.mainScreen.bounds), CGRectGetHeight(UIScreen.mainScreen.bounds));
self.originFrame = self.presentView.frame;
[UIView animateWithDuration:ZXYAnimationDuration animations:^{
self.presentView.transform = CGAffineTransformMakeRotation(M_PI_2);
self.presentView.frame = frame;
} completion:^(BOOL finished) {
}];
}
- (void)exitFullScreen {
[UIView animateWithDuration:ZXYAnimationDuration animations:^{
self.presentView.transform = CGAffineTransformIdentity;
self.presentView.frame = self.originFrame;
} completion:^(BOOL finished) {
}];
