iphone - 在 ISGL3D 中，我们一次只能识别一个 Gesture

Question

我正在 ISGL3D 中开发一个应用程序。我一次只需要识别一个手势

即PICNH或PAN ..

有没有办法做到这一点？

Answer 1

您必须实现该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;
}
