在ISGL3D中，我们一次只能识别一个手势吗？

Question

我正在开发ISGL3D中的应用程序。我需要一次只识别一个手势

即。 PICNH或PAN ..

有没有办法做到这一点??

Answer 1

您必须实施UIGestureRecognizerDelegate方法gestureRecognizer:shouldRecognizeSimultaneouslyWithGestureRecognizer:和return NO

Answer 2

您可以使用此功能一次仅识别一个手势：

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

    return YES;
}
