我正在尝试使用 Page Curl 动画推送视图控制器。我创建了一个有效的自定义 Segue:
- (void) perform {
UIViewController *src = (UIViewController *) self.sourceViewController;
UIViewController *dst = (UIViewController *) self.destinationViewController;
[UIView transitionFromView:src.view
toView:dst.view
duration:0.6
options:UIViewAnimationOptionTransitionCurlUp
completion:^(BOOL finished) {
[src.navigationController pushViewController:dst animated:NO];
}
];
}
当我尝试改变卷曲的方向时,问题就来了。我尝试使用或多或少像这里描述的容器。但也无法让它工作。
- (void) perform
{
UIViewController *src = (UIViewController *) self.sourceViewController;
UIViewController *dst = (UIViewController *) self.destinationViewController;
UIView* parent = src.navigationController.view;
UIView* containerView = [[UIView alloc] initWithFrame:parent.frame];
[parent addSubview:containerView];
containerView.transform = CGAffineTransformMakeRotation(M_PI);
[containerView addSubview:src.view];
src.view.transform = CGAffineTransformMakeRotation(-M_PI);
[UIView transitionFromView:containerView
toView:dst.view
duration:0.6
options:UIViewAnimationOptionTransitionCurlUp
completion:^(BOOL finished) {
[src.navigationController pushViewController:dst animated:NO];
}
];
}
这可能吗?
谢谢。
