删除uiwindow的子视图? [英] remove subview of uiwindow?

问题描述

我想从uiwindow中删除一个视图，所以我在appdelegate方法中使用nslog，它说窗口的子视图数为两个NSLog(@" %d",[[self.window subviews] count]);，所以如何从窗口中删除该子视图，如果我删除了该子视图，我可以使用选项卡栏控制器继续...

i want to remove a view from uiwindow,so i nslog in appdelegate method,it says window's subviews count as two NSLog(@" %d",[[self.window subviews] count]); so how can i remove that subviews from window,if i remove that subviews i have tab bar controller to be continued...

- (void) GetUserCompleted

{
    NSLog(@"   %@",[[self.window subviews] objectAtIndex:0]);   
    NSLog(@"   %@",[[self.window subviews] objectAtIndex:1]); 
}

推荐答案

您可以使用以下代码删除单个子视图.

You can remove the a single subview using the following code.

[subview_Name removeFromSuperview];

如果要从视图中删除所有子视图，请使用它.

if you want to remove all subviews form the view then use this.

NSArray *subViewArray = [self.window subviews];
for (id obj in subViewArray)
{
    [obj removeFromSuperview];
}
