在dismissModalViewControllerAnimated之后调用popToRootViewControllerAnimated

Question

我正在工作的应用程序,我打电话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不能正常工作.

代码如下所示:

[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]; 
}

它不是那么整洁但它应该工作.

更新: 你应该使用

 [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.
