使用 UIPanGestureRecognizer UINavigationController 向后滑动不起作用

Question

在cellForRowAtIndexPath创建cell时，我还把UIPanGestureRecognizer添加到cell，并根据要求实现了所有处理。

这个Tableview包含在myViewController中，而myViewController又包含在UINavigationController中。

使用UIPanGestureRecognizer UINavigationController 向后滑动不起作用。

当用户开始从手机的最左侧滑动时，我该怎么做？它执行 UINavigationController swipe to back 而不是我的手机平移手势。

-(void)move:(PanGestureRecognizer *)gesture {

    CGPoint location = [gesture locationInView:self];
    NSIndexPath *swipedIndexPath = [self indexPathForRowAtPoint:location];
    TableViewCell *swipedCell  = [self cellForRowAtIndexPath:swipedIndexPath];
    CGRect cellRect = swipedCell.frame;

    if(location.x < 75) {
       ?????
    }

.

.
//my pan gesture required functionality
}


-(BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldRecognizeSimultaneouslyWithGestureRecognizer:(UIGestureRecognizer *)otherGestureRecognizer
{
    return YES;
}

Answer 1

使用requireGestureRecognizerToFail。

在您的 viewController 中调用：[yourPanGesture requireGestureRecognizerToFail:self.navigationController.interactivePopGestureRecognizer

或

[cell.gestureRecognizers enumerateObjectsUsingBlock:^(__kindof UIGestureRecognizer * _Nonnull obj, NSUInteger idx, BOOL * _Nonnull stop) {
        if ([obj isKindOfClass:[UIPanGestureRecognizer class]]) {
            [obj requireGestureRecognizerToFail:interactivePopGestureRecognizer];
        }
    }];
