问题描述

我在调用方法dismissView 时收到此错误.这是方法存根:

I am getting this error when I call my method dismissView. Here is the method stub:

-(IBAction)dismissView
{
    RootViewController *rootController = [[RootViewController alloc] initWithNibName:@"RootViewController" bundle:nil];
    [self.navigationController popToViewController:rootController animated:YES];
}

这应该可行,而且我已经检查过,rootController 已初始化并分配.有什么想法吗?

That should work, and I've checked, rootController is initialized and allocated. Any ideas?

推荐答案

我最近遇到了这个问题,用这样的东西解决了......

I had this problem recently and solved with something like this...

[self.navigationController popToViewController:[self.navigationController.viewControllers objectAtIndex:1] animated:YES];
