ios – 在dismissModalViewControllerAnimated之后调用popToRootViewControllerAnimated

我正在工作的应用程序,我调用presentModalViewController,一旦完成(调用dismissModalViewControllerAnimated：YES)它应立即调用popToRootViewControllerAnimated.

但问题是dismissModalViewControllerAnimated：YES工作正常,但popToRootViewControllerAnimated在它之后无法正常工作.

代码如下所示：

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

解决方法

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]; 
}

它不是那么整洁但它应该工作.

更新：
你应该用

[self dismissModalViewControllerAnimated:YES];

代替

[self.navigationController dismissModalViewControllerAnimated:YES] ;

呈现模态的对象是视图控制器,而不是导航控制器.
