iOS : Resizing subview by removing a subview

Question

• 我有一个包含 3 个 subview 的 View ，分别称为 view A、view B、view C。
• 当我删除 subview 时，意味着我需要自动设置边距以进行调整。
• 当我删除 view A 意味着，剩余的 views 必须自动向上移动。

注意:不在autolayout中。请告诉它如何在 automask

中实现

它不会自动工作，你需要编程一下，你可以试试下面的代码来实现，

//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;
        }];

    }
}

希望对你有帮助。

干杯。
