问题描述
我已设置以下动画以在不同大小的视图之间旋转。随着新的,更高的视图进入视野,动画的中点似乎有一个闪烁。我能做些什么来平滑过渡。
I have set up the following animation to rotate between views of different sizes. The midpoint of the animation seems to have a flicker as the new, taller view comes into view. Is there anything I can do to smoothen the transition.
newView.layer.transform = CATransform3DMakeRotation(M_PI_2, 0.0, 1.0, 0.0);
[UIView animateWithDuration:0.5
delay:0
options:UIViewAnimationOptionCurveLinear
animations:^{oldView.layer.transform = CATransform3DMakeRotation(M_PI_2, 0.0, -1.0, 0.0);}
completion:^(BOOL finished) {
[oldView removeFromSuperview];
[UIView animateWithDuration:0.5
delay:0
options:UIViewAnimationOptionCurveLinear
animations:^{newView.layer.transform = CATransform3DMakeRotation(M_PI_2, 0.0, 0.0, 0.0);}
completion:nil];
}];
推荐答案
我已经到了一半,但缺少一块,设置转换矩阵的m34单元格值 ,诀窍。
I was halfway there, but the missing piece, setting the m34 cell value of the transformation matrix, did the trick.
