ios - 在 dismissModalViewControllerAnimated 之后调用 popToRootViewControllerAnimated

Question

我正在调用 presentModalViewController 的应用程序一旦完成(调用 dismissModalViewControllerAnimated:YES )它应该立即调用 popToRootViewControllerAnimated .

但问题是dismissModalViewControllerAnimated:YES工作正常但popToRootViewControllerAnimated在它之后不工作。

代码如下:

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

Answer 1

尝试这样的事情:

[self.navigationController dismissModalViewControllerAnimated:YES] ;
[self performSelector:@selector(patchSelector) withObject:nil afterDelay:0.3];


-(void)patchSelector{
  [self.navigationController popToRootViewControllerAnimated:YES]; 
}

它不是很整洁，但应该可以。

更新:你应该使用

 [self dismissModalViewControllerAnimated:YES];

代替

 [self.navigationController dismissModalViewControllerAnimated:YES] ;

呈现模态的对象是 View Controller ，而不是导航 Controller 。
