UIView未从superview中删除

Question

我在从superview中删除视图时遇到问题。 添加视图：

- (void)createCircles
{
    NSString *currentDate = [self currentDate];
    NSArray *array = [self.horizontalScroll subviews];
    UILabel *label = nil;
    for (label in array)
    {
        if ([label.text isEqualToString:currentDate])
        {
            UIView *view = [[UIView alloc] initWithFrame:label.frame];
            view.backgroundColor = [UIColor redColor];
            [self.horizontalScroll insertSubview:view atIndex:0];
            [self.labelsArray insertObject:view atIndex:0];
        }
    }
}

尝试删除：

- (void)labelTouch:(UITapGestureRecognizer*)sender
{
    NSArray *array = [self.horizontalScroll subviews];
    UILabel *label = (UILabel*)sender.view;
    for (int i = 0; i < [array count]; ++i)
    {
        UILabel *l = array[i];
        if (label.tag == l.tag)
        {
            UIView *view = nil;
            view = [self.labelsArray objectAtIndex:0];
            view.hidden = YES;
            [view removeFromSuperview];
            view = nil;
            [self.labelsArray removeObjectAtIndex:0];
        }
    }
}

但触摸视图仍然显示后。试图删除标签（l） - 它被删除

Answer 1

试试这个，

 [[[self.horizontalScroll subviews] objectAtIndex:0] removeFromSuperView];

Answer 2

您应该在ivar或property中存储对此“unkillable”视图的引用。在第一个方法中初始化它并在第二个方法中调用removeFromSupperView。
