推荐答案
将下面的code在您的视图控制器:
Put the following code in your view controller:
CATransform3D t3d = CATransform3DIdentity;
// m34 sets the amount of perspective
t3d.m34 = 1.0/-1000.0;
[UIView animateWithDuration:1.0
delay:0.0
options:UIViewAnimationCurveLinear
animations:^{
self.view.layer.transform = CATransform3DRotate(t3d, M_PI, 0, 1, 0);
}
completion:^(BOOL finished) {
[UIView animateWithDuration:1.0
delay:0.0
options:UIViewAnimationCurveLinear
animations:^{
self.view.layer.transform = CATransform3DRotate(t3d, 2*M_PI, 0, 1, 0);
}
completion:^(BOOL finished) {
self.view.layer.transform = CATransform3DIdentity;
}];
}];
这是pretty凌乱,如果任何人有关于如何清除这件事有任何建议,让我知道;)
It's pretty messy, if anybody has any suggestions on how to clear this up, let me know ;)
