UIPanGestureRecognizer：手指下的偏移视图

Question

我有一个带有一些UIViews的scrollView作为我拖动的子视图。问题是子视图相当小，拖动它们时，你看不到它们，因为手指挡住了。

拖动时如何向上偏移视图？

由于

if (recognizer.state == UIGestureRecognizerStateChanged)
{
    CGPoint translation = [recognizer translationInView:self];
    draggingView.center = CGPointMake(draggingView.center.x + translation.x,
                                      draggingView.center.y + translation.y);

    [recognizer setTranslation:CGPointZero inView:self];
}

Answer 1

尝试以下代码  CGPoint touchPoint = [recognizer locationInView:self]; 尝试更改touchPoint
