在表格视图中滑动一行，单击其他，选择滑动

Question

我有一个表格视图，每当我在 A 部分中滑动一行，然后在 B 部分中选择一行时，它认为我在 A 部分中选择了滑动的行！我放置了一个断点来验证，并且 100% 确定它认为是该单元格，并且当我选择 B 部分中的行时它会调用它。

通过滑动，我的意思是您将手指放在单元格的某个部分，然后拖动它穿过（左或右，无关紧要），然后释放它。这不会调用 didSelectRowAtIndexPath，因为它不是点击。

示例：
在索引路径 A.1 上滑动
点击索引路径 B.4
操作系统调用 tableView:didSelectRowAtIndexPath: A.1

我做错了什么吗？可能会出什么问题？

处理特定单元格中的触摸的完整代码：

- (void) touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {
    RDLogString(@"(%p) Received touches began", self);
    moveCount = 0;
    UITouch * touch = [touches anyObject];
    touchBegin = [touch locationInView: nil];
    [[self nextResponder] touchesBegan: touches withEvent: event];
}

- (void) touchesMoved: (NSSet * const)touches withEvent:(UIEvent * const)event {
    RDLogString(@"(%p) Received touches moved", self);
    moveCount++;
    [[self nextResponder] touchesMoved: touches withEvent: event];
}

- (void) touchesEnded: (NSSet * const)touches withEvent:(UIEvent * const)event {
    RDLogString(@"(%p) Received touches ended", self);
    if(![self checkUserSwipedWithTouches: touches]){
        [[self nextResponder] touchesEnded: touches withEvent: event];
    }
}

- (BOOL) checkUserSwipedWithTouches: (NSSet * const) touches {
    CGPoint touchEnd = [[touches anyObject] locationInView: nil];
    NSInteger distance = touchBegin.x - touchEnd.x;

    // This code shows an animation if the user swiped
    if(distance > SWIPED_HORIZONTAL_THRESHOLD){
        [self userSwipedRightToLeft: YES];
        return YES;
    } else if (distance < (-SWIPED_HORIZONTAL_THRESHOLD)) {
        [self userSwipedRightToLeft: NO];
        return YES;
    }

    return NO;
}

我修复了这个问题，当检测到并处理滑动时，我现在不再发送任何内容，而是发送 TouchsCancelled ，回想起来我必须承认，这很有意义，但目前还不清楚我应该这样做。如果您不希望处理该操作，我找不到有关该怎么做的正确文档。

有效的代码：

- (void) touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {
    moveCount = 0;
    UITouch * touch = [touches anyObject];
    touchBegin = [touch locationInView: nil];
    [[self nextResponder] touchesBegan: touches withEvent: event];
}

- (void) touchesMoved: (NSSet * const)touches withEvent:(UIEvent * const)event {
    moveCount++;
    [[self nextResponder] touchesMoved: touches withEvent: event];
}

- (void) touchesEnded: (NSSet * const)touches withEvent:(UIEvent * const)event {
    // If we DO NOT handle the touch, send touchesEnded
    if(![self checkUserSwipedWithTouches: touches]){
        [[self nextResponder] touchesEnded: touches withEvent: event];
    } else { // If we DO handle the touch, send a touches cancelled. 
        self.selected = NO;
        self.highlighted = NO;
        [[self nextResponder] touchesCancelled: touches withEvent: event];
    }
}
