在dismissModalViewControllerAnimated之后调用popToRootViewControllerAnimated

本文介绍了在dismissModalViewControllerAnimated之后调用popToRootViewControllerAnimated的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我正在使用的应用程序中，我调用presentModalViewController，一旦完成(调用dismissModalViewControllerAnimated:YES)，它应立即调用popToRootViewControllerAnimated.

I am working application in which i calling presentModalViewController and once finished(calling dismissModalViewControllerAnimated:YES) it should immediately call popToRootViewControllerAnimated.

但是问题是dismissModalViewControllerAnimated:YES正常工作，但popToRootViewControllerAnimated之后却无法工作.

But the issue is dismissModalViewControllerAnimated:YES is working properly but popToRootViewControllerAnimatedis not working after it.

代码如下所示:

[self.navigationController dismissModalViewControllerAnimated:YES] ; [self.navigationController popToRootViewControllerAnimated:YES];

推荐答案

尝试如下操作:

[self.navigationController dismissModalViewControllerAnimated:YES] ; [self performSelector:@selector(patchSelector) withObject:nil afterDelay:0.3]; -(void)patchSelector{ [self.navigationController popToRootViewControllerAnimated:YES]; }

它不是那么整洁，但是应该可以工作.

It is not so neat but it should work.

更新: 您应该使用

[self dismissModalViewControllerAnimated:YES];

代替

[self.navigationController dismissModalViewControllerAnimated:YES] ;

呈现模式的对象是视图控制器，而不是导航控制器.

The object that is presenting the modal is the view controller, not the navigation controller.
