如何在iOS中删除带幻灯片的SubView？

Question

我尝试在代码后添加带动画的SubView.没关系.

[self.view addSubview:pickerView];
    pickerView.frame = CGRectMake(0, 0, 320, 50);
    [UIView animateWithDuration:1.0 
                     animations:^{
                         pickerView.frame = CGRectMake(0, 152, 320, 260);
                     }];

我还想删除像上面动画一样的幻灯片动画的子视图.

我怎样才能做到这一点？

提前致谢.

您可以使用此animateWithDuration完成块来删除视图

[UIView animateWithDuration:1.0 
                 animations:^{
                     pickerView.frame = //move it out of screen
                 } completion:^(BOOL finished) {
                     [pickerView removeFromSuperView];
                 }];
