ios - UIPanGestureRecognizer:手指下的偏移 View

Question

我有一个带有一些 UIView 作为我拖来拖去的 subview 的 scrollView。问题是 subview 很小，拖动它们时，手指挡住了它们，您看不到它们。

如何在拖动时稍微向上偏移 View ？

谢谢

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

试试下面的代码 CGPoint touchPoint = [识别器locationInView:self];尝试改变接触点
