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;
}
