objective-c - 如何在单击按钮时在同一窗口中加载新 View ？

Question

我有一个带按钮的 View Controller 。我希望在按下按钮时通过我的 View-Controller 加载新 View 。它不会替换现有 View ，我希望它小于屏幕并在我点击小 View 时隐藏。

应该如何在代码中实现？

Answer 1

- (IBAction)button:(id)sender 
{
UIView *view2=[[UIView alloc]initWithFrame:CGRectMake(0,0,200,200)];
[self.view addSubview:view2];
UITapGestureRecognizer *Tap = [[[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(Tapview)] autorelease];
[view2 addGestureRecognizer:Tap];
}

-(void)Tapview
{
[view2 removeFromSuperview];
}
