ios - 如何从 superView 中删除 View？

Question

我制作了一个 xib 并通过以下代码在 View 中显示它。

    NSArray *xibContents = 
        [[NSBundle mainBundle] loadNibNamed:@"PickupAddressView"
            owner:self 
            options:nil];

    UIView *view = [xibContents objectAtIndex:0]; // Safer than objectAtIndex:0
    //UIView *subView=[view.subviews objectAtIndex:0];

    [view setFrame:CGRectMake(0.0f, 0.0f, 0.0f, 0.0f)];
    CGRect tempFrame=view.frame;
    tempFrame.size.width=300;//change acco. how much you want to expand
    tempFrame.size.height=350;
    [UIView beginAnimations:@"" context:nil];
    [UIView setAnimationDuration:0.2];
    view.frame=tempFrame;
    //[UIView commitAnimations];
    [view setFrame:CGRectMake(10.0f, 90.0f, 300.0f, 350.0f)];
    [view setBackgroundColor:
      [UIColor colorWithPatternImage:
        [UIImage imageNamed:@"Register_bg"]]];
    [UIView commitAnimations];

    [view removeFromSuperview];
    [self.view addSubview:view];

我正在使用 UIStoryboard，并制作了这个 xib 并通过以下代码显示。

如何删除此 View 。我有一个 UIButton，正在调用其 IBAction。

谢谢

保留对 View 的弱引用(属性或实例变量)并像这样调用 removeFromSuperview:

[self.viewToRemove removeFromSuperview];
