问题描述

如何才能在使用 UIScrollView 时不调用平移手势识别器选择器.

How can I make it so that when I use my UIScrollView the pan gesture recognizer selector is not called.

我希望能够在不调用平移手势选择器的情况下在滚动视图中滚动.

I want to be able to scroll in the scroll view without the pan gesture selector being called.

这是我的平移检测功能:

Here is my pan detected function:

- (void)panDetected:(UIPanGestureRecognizer *)panRecognizer
{

    CGPoint translation = [panRecognizer translationInView:self.view];
    CGPoint imageViewPosition = self.draggableImage.center;
    imageViewPosition.x += translation.x;
    imageViewPosition.y += translation.y;

    self.draggableImage.center = imageViewPosition;
    [panRecognizer setTranslation:CGPointZero inView:self.view];
}

我不希望在页面底部使用 UIScrollView 时调用它.

I do not want it to be called when I am using my UIScrollView at the bottom of the page.

推荐答案

您可以从滚动视图中移除手势识别器

you could remove the gesture recognizer from the scroll view

NSArray* gestureRecognizers = [scrollView gestureRecognizers];
for (UIGestureReconizer* recog in gestureRecognizers) {
    if ( [recog isKindOfClass:[UIPanGestureRecognizer Class]] )
        [recog removeTarget:scrollView.delegate action:@selector(scrollViewDidScroll:)];
}

我不明白为什么需要这样做,但就是这样.

I don't understand why this is needed to be done, but here it is.
