我在 FirstViewController 中有这样的代码

{
SecondViewController *objComing=[[SecondViewController alloc] init];
[self.view addSubview:objComing.view];

objComing.view.backgroundColor=[UIColor blueColor];

objComing.view.frame=CGRectMake(0,420, 320, 0);
[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:0.5];

[UIView setAnimationCurve:UIViewAnimationCurveEaseIn];
objComing.view.frame=CGRectMake(0,0, 320, 420);

[UIView commitAnimations];
}

SecondViewController 包含关闭/关闭按钮。应该如何查看连接到按钮的 IBAction（包含在 SecoundViewController 中）以解除/删除和隐藏此覆盖层？

在关闭/关闭按钮方法中添加以下行以删除 secondviewcontroller 子视图：

[self.view removeFromSuperview];
