UIView使用块动画方法设置幻灯片但不会滑出

Question

我有一个叫做geopointView的UIView.我想在按下按钮(myButton)时在主视图框架上为此UIview中的幻灯片设置动画.如果再次按下myButton,UIview应该滑出框架.myButton调用以下方法"optionsCalled"

-(void) optionsCalled
{
if (![[self.view subviews] containsObject:geopointView] &&checkForGeopointViewAnimation ==0) {

        [self.view addSubview:geopointView];
        geopointView.frame = CGRectMake(0,430,320,30);
        [UIView animateWithDuration:0.3f 
                         animations:^{
                             geopointView.frame = CGRectMake(0, 350, 100, 80);
                         }
                         completion:^(BOOL finished){
                             checkForGeopointViewAnimation = 1 ;
                         }];

    }
    if ([[self.view subviews] containsObject:geopointView] && checkForGeopointViewAnimation ==1)
    {

        geopointView.frame = CGRectMake(0, 350, 100, 80);
        [UIView animateWithDuration:0.3f 
                         animations:^{
                             geopointView.frame = CGRectMake(0,430,320,30);
                         }
                         completion:^(BOOL finished){
                             checkForGeopointViewAnimation = 0 ;
                         }];

        [geopointView removeFromSuperview];

    }

}

这里checkForGeopointViewAnimation是一个全局变量,定义为确保一次不调用滑入和滑出.

此代码的问题在于UIview以动画方式滑动,但它不会为幻灯片操作设置动画.它只是从主框架消失.我是否需要在这里使用任何时间,以便延迟调用添加和删除UIview功能？

在此先感谢您的帮助

[geopointView removeFromSuperview];完成动画后尝试
