Question

我有一位观点控制者,通过“[自己的观点加上:第二观点]”补充了另一种观点。问题是,第二个观点在半部分之外增加。

secondView = [[SecondView alloc] initWithFrame: CGRectMake (-160, 0, 320, 460)];
[self.view addSubview: secondView.view]; "

然而,我已经注意到,0(-160)之前的那部分并非相互猜疑。这是正常的吗? 是否有办法解决?

谢谢!

Answer 1

我担心,考虑到<代码>的方式。 UIResponderchain work, 您所希望的是什么是无法直接的(超级概览只能传达给其认为影响自身的事件)。

On the other hand, if you really need to have this view outside of its parent s frame, you could associate a gesture recognizer (reference) to the subview. Indeed, gesture recognizers are handled outside the normal touch event dispatching and it should work.

用于主轴:

UITapGestureRecognizer *singleTap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(handleSingleTap:)];
[secondView addGestureRecognizer:singleTap];

您可以允许通过压倒一切的<代码>点:有:接受母体外的接触。

- (BOOL)pointInside:(CGPoint)point withEvent:(UIEvent *)event
{
    BOOL pointInside = NO;

    // step through our subviews  frames that exist out of our bounds
    for (UIView *subview in self.subviews)
    {
        if(!CGRectContainsRect(self.bounds, subview.frame) && [subview pointInside:[self convertPoint:point toView:subview] withEvent:event])
        {
            pointInside = YES;
            break;
        }
    }

    // now check inside the bounds
    if(!pointInside)
    {
         pointInside = [super pointInside:point withEvent:event];
    }

    return pointInside;
}
