iphone - 控制 UIScrollView 越界？

Question

我想知道如何让用户滚动到 UIScrollView 的边界之外？

Answer 1

您可以尝试将触摸事件从 super View 的各种 UIView 方法转发到 ScrollView ，看看是否可行。例如:

- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
{
    [scrollView touchesBegan:touches withEvent:event];
}
// etc

或者您可以尝试在 super View 上使用 UIPanGestureRecognizer 并在获取平移事件时显式设置 ScrollView 偏移量。例如:

- (void)handlePan:(UIPanGestureRecognizer *)pan
{
    scrollView.contentOffset = [pan translationInView:scrollView];
}
// Or something like that.
