Answer 1

It will not work automatically, you need to program a bit, you can try the following code to achieve this,

//Adding Delete Tap Gesture
-(void)addGestureToSubViews{
    for(UIView *view in parent.subviews){
        UITapGestureRecognizer *gesture=[[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(deleteAction:)];
        [view addGestureRecognizer:gesture];
    }
}


-(IBAction)deleteAction:(UITapGestureRecognizer *)sender{
    UIView *view=sender.view;

    [UIView animateWithDuration:.3 animations:^{
        CGRect rect=view.frame;
        rect.origin.x=view.superview.frame.size.width;
        view.frame=rect;
    } completion:^(BOOL finished) {
        [self reArrangeSuperView:view.superview withDeletedViewFrame:view.frame];
        [view removeFromSuperview];

    }];

}

-(void)reArrangeSuperView:(UIView *)superView withDeletedViewFrame:(CGRect)frame{

    for(UIView *view in superView.subviews){
        CGRect rect=view.frame;

        if(rect.origin.y>frame.origin.y){
            rect.origin.y=frame.origin.y;
        }

        [UIView animateWithDuration:.3 animations:^{
            view.frame=rect;
        }];

    }
}

I hope it helps.

Cheers.

为此，您必须在属性检查器中隐藏视图，并且要向上推哪个视图，应设置视图的-contentoffset属性。
