Question

我有这个故事板：

TabBarController：Tab1＆gt; NavigationController＆gt; VC1＆gt; VC3

// VC1.m
[self performSegueWithIdentifier:@"VC2" sender:self];

// VC2.m
[self performSegueWithIdentifier:@"VC3" sender:self];

我希望VC1和VC2之间的转换是淡入淡出动画，但VC2和VC3之间的转换是默认动画。

但是我必须做一个push segue而不是模态来保持UINavigationController的好处（除非我错过了什么）。我找到的所有解决方案都使用presentViewController。

Answer 1

尝试使用此CATransition

 CATransition *transition = [CATransition animation];
 transition.duration = 0.3;
 transition.type = kCATransitionFade;

 [navigationController.view.layer addAnimation:transition forKey:kCATransition];
 isPush ? [navigationController pushViewController:viewController animated:NO] : [navigationController popViewControllerAnimated:NO];

Answer 2

如果你坚持使用segue而不是我看到两种方式：

1）使用UIViewControllerAnimatedTransitioning协议并按照喜欢的方式自定义转换。

2）编写自定义UIStoryboardSegue

或者通过操纵控制器及其视图和框架来执行您自己的过渡和动画，如：

- (void)transitionToChildViewController:(UIViewController *)toViewController {

UIViewController *fromViewController = ([self.childViewControllers count] > 0 ? self.childViewControllers[0] : nil);
if (toViewController == fromViewController || ![self isViewLoaded]) {
    return;
}

UIView *toView = toViewController.view;
[toView setTranslatesAutoresizingMaskIntoConstraints:YES];
toView.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight;
toView.frame = self.privateContainerView.bounds;

[fromViewController willMoveToParentViewController:nil];
[self addChildViewController:toViewController];
[self.privateContainerView addSubview:toView];
[fromViewController.view removeFromSuperview];
[fromViewController removeFromParentViewController];
[toViewController didMoveToParentViewController:self];

}

最后一种方法也许是最乏味的。
