Question

我想从uiwindow中删除一个视图，所以我在appdelegate方法中使用nslog，它说窗口的子视图计为两个NSLog(@" %d",[[self.window subviews] count]);所以如何从窗口中删除该子视图，如果我删除那些子视图我有标签栏控制器继续......

- (void) GetUserCompleted

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

Answer 1

您可以使用以下代码删除单个子视图。

[subview_Name removeFromSuperview];

如果要从视图中删除所有子视图，请使用此视图。

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

Answer 2

希望以下代码对删除特定视图非常有用

   Set tag for that remove view

   subview.tag = 1;

   then

   [[[self window] viewWithTag:1] removeFromSuperview];

@Maddy答案的快速版本：

Public Class Form1

Sub New()

    InitializeComponent()

    WindowState = FormWindowState.Maximized
    Size = New Size(Screen.PrimaryScreen.WorkingArea.Width, Screen.PrimaryScreen.WorkingArea.Height)

    Dim p1 As New Panel()
    p1.Location = New Point(10, 10)
    p1.Size = New Size(ClientSize.Width - 20, ClientSize.Height - 20)
    p1.BackColor = Color.Blue

    Controls.Add(p1)

End Sub

End Class

删除uiwindow的子视图？
