在 ISGL3D 中，我们一次只能识别一个手势吗

Question

我正在用 ISGL3D 开发一个应用程序。我一次只需要识别一个手势

即PICNH 或 PAN..

有什么办法吗？

Answer 1

你必须实现UIGestureRecognizerDelegate方法gestureRecognizer:shouldRecognizeSimultaneouslyWithGestureRecognizer:和return NO

Answer 2

您可以使用此功能一次只识别一个手势：

- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldRecognizeSimultaneouslyWithGestureRecognizer:(UIGestureRecognizer *)otherGestureRecognizer
{
    if (gestureRecognizer.view != otherGestureRecognizer.view)
        return NO;

    return YES;
}
