Question

在UITableView上，我使用自定义单元格代码：

-(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {
    UITouch *touch = [touches anyObject];
    gestureStartPoint = [touch locationInView:self.contentView];
}

-(void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event {
    UITouch *touch = [touches anyObject];
    CGPoint currentPosition = [touch locationInView:self.contentView];    

    CGFloat deltaX = fabsf(gestureStartPoint.x - currentPosition.x);
    CGFloat deltaY = fabsf(gestureStartPoint.y - currentPosition.y);


    if(deltaX < kMinimumGestureLength && deltaY < kMaximumVariance&&!swiped){
        //do something 
        NSLog(@"Tapped %d",indexRow);
        //return YES;
    } else if(deltaX < kMinimumGestureLength && deltaY < kMaximumVariance&&swiped) {
        swiped = FALSE;
    }

}

-(void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event{
    UITouch *touch = [touches anyObject];
    CGPoint currentPosition = [touch locationInView:self.contentView];    

    CGFloat deltaX = fabsf(gestureStartPoint.x - currentPosition.x);
    CGFloat deltaY = fabsf(gestureStartPoint.y - currentPosition.y);


    if(deltaX >= kMinimumGestureLength && deltaY <= kMaximumVariance){
        //do something 
        NSLog(@"Swiped %d",indexRow);
        gestureStartPoint = [touch locationInView:self.contentView];
        swiped = TRUE;
    }
    else if(deltaY >= kMinimumGestureLength && deltaX <= kMaximumVariance){
        //do something
    }
}

在我添加之前，didSelectRowAtIndexPath被调用，但是，现在它不是。我可以评论该部分，它工作正常。有人知道解决这个问题的方法吗？

编辑：发布工作代码

Answer 1

我不是100％肯定，但我认为您需要调用超级方法才能继续保持默认行为。

[super touchesBegan:...];

[super touchesEnded:...];

[super touchesMoved:...];

每个人都有自己的方法。

Answer 2

这似乎与this question相似。尝试使用[super touchesbegan] et al。

调用父方法

TableView didSelectRowAtIndexPath未被调用
