objective-c - 使用 UIViewAnimationOptionTransitionCurlDown 自定义 Segue

Question

我想创建一个自定义 segue 以将 ViewController 与 curl up 动画交换，但我找不到方法，-(void)perform 是什么？

我知道了

-(void)perform{
    UIViewController *dst = [self destinationViewController];
    UIViewController *src = [self sourceViewController];    
    [UIView beginAnimations:nil context:nil];
    //change to set the time
    [UIView setAnimationDuration:1];
    [UIView setAnimationBeginsFromCurrentState:YES];
    [UIView setAnimationTransition:UIViewAnimationTransitionCurlUp forView:src.view    cache:YES];
    [UIView commitAnimations];
}

但我无法改变 View ，无论如何感谢您的帮助!

没关系，我解决了它，为了记录，我唯一要做的就是添加一个导航 Controller ，然后我可以使用自定义 segues，例如:

- (void) perform {
    UIViewController *src = (UIViewController *) self.sourceViewController;
    UIViewController *dst = (UIViewController *) self.destinationViewController;
    [UIView transitionWithView:src.navigationController.view duration:0.3
                       options:UIViewAnimationOptionTransitionFlipFromBottom
                    animations:^{
                        [src.navigationController pushViewController:dst animated:NO];
                    }
                    completion:NULL];
}
