ios - 如何通过点击使 UIView 移动？

Question

我不确定我是否可以正确描述它。它是一种 UIView，我们只能看到它的一部分(可能带有箭头。在屏幕底部，可能)。用户可以点击它，这个 View 会全屏显示(通常开发者会留下一些额外的信息)。我怎样才能做到？

试试这个:

-(void)show
{
    [viewObj setFrame:CGRectMake(viewObj.frame.origin.x,viewObj.frame.origin.y,viewObj.frame.size.width, viewObj.frame.size.height)];//Here "viewObj.frame.origin.y" means 568
    [UIView animateWithDuration:0.5 animations:^
     {
         [viewObj setFrame:CGRectMake(viewObj.frame.origin.x,0,viewObj.frame.size.width, viewObj.frame.size.height)];
     }
     completion:^(BOOL finished)
     {
     }];
}

-(void)hide
{
    [viewObj setFrame:CGRectMake(viewObj.frame.origin.x,viewObj.frame.origin.y,viewObj.frame.size.width, viewObj.frame.size.height)];//Here "viewObj.frame.origin.y" means 0
    [UIView animateWithDuration:0.5 animations:^
     {
         [viewObj setFrame:CGRectMake(viewObj.frame.origin.x,568,viewObj.frame.size.width, viewObj.frame.size.height)];
     }
     completion:^(BOOL finished)
     {
     }];
}
