Question

我一直在尝试构建自定义的uitableview滑动。我很成功。我还想在遇到touchesMoved时将uiview作为子视图添加到tablecell。当我试图移动tablecell时，我希望uiview被附加到静止状态。为此，我也在向opp方向移动（正如StackOverflow中的一个答案所示）。但它并不是固定的。子视图也随着单元格一起移动。请帮我看看我哪里出错了？代码如下：

- (void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event 
{
UITableViewCell * cell = (UITableViewCell *)[self cellForRowAtIndexPath:[self indexPathForRowAtPoint:gestureStartPoint]];
isTouchesMoved=YES;

if ([self supportsSwipingForCellAtPoint:gestureStartPoint])
{

    [NSObject cancelPreviousPerformRequestsWithTarget:self selector:@selector(highlightTouchedRow) object:nil];

    UITouch * touch = [touches anyObject];
    CGPoint currentPosition = [touch locationInView:self];
    CGFloat deltaX = fabsf(gestureStartPoint.x - currentPosition.x);
    CGFloat deltaY = fabsf(gestureStartPoint.y - currentPosition.y);
    if (deltaX >= kMinimumGestureLength && deltaY <= kMaximumVariance)
    {
        tempView=[self addnewViewatPoint:touches withEvent:event];
        [cell addSubview:tempView];
        [self setScrollEnabled:NO];
        CGPoint loc = [touch locationInView:self];
        CGPoint prevloc = [touch previousLocationInView:self];
        if(moved==TRUE)
        {
            prevLoc=cell.frame;
            prevLocBack=tempView.frame;
            moved=FALSE;
        }
        CGRect myFrame = cell.frame;
        CGRect backFrame = tempView.frame;
        CGFloat deltaX = loc.x - prevloc.x;
        if(gestureStartPoint.x>currentPosition.x)
        {
            NSLog(@"You have swiped left");
            CGFloat movedDistance=gestureStartPoint.x-currentPosition.x;
            NSLog(@"The movedDistance is %f",movedDistance);
            if(movedDistance<=160)
            {
                myFrame.origin.x += deltaX;
                backFrame.origin.x-=deltaX;
                NSLog(@"The backgroundViewframe position, frameposition is %f and %f",fabsf(backFrame.origin.x),fabsf(myFrame.origin.x));
            }
            [tempView setFrame:backFrame];
            [cell setFrame:myFrame];

        }
        else 
        {
            NSLog(@"You have swiped right");
            CGFloat movedDistance=currentPosition.x-gestureStartPoint.x;
            NSLog(@"The movedDistance is %f",movedDistance);
            if(movedDistance<=160)
            {
            myFrame.origin.x += deltaX;
                            backFrame.origin.x-=deltaX;
            }
            [cell setFrame:myFrame];
        }
        if ([swipeDelegate respondsToSelector:@selector(tableView:didSwipeCellAtIndexPath:)])
        {
            [swipeDelegate tableView:self didSwipeCellAtIndexPath:[self indexPathForRowAtPoint:gestureStartPoint]];
        }

        [self setIndexOfVisibleBackView:[self indexPathForCell:cell]];
    }

    [self setScrollEnabled:YES];

}
else
{
    [super touchesMoved:touches withEvent:event];
}
}


-(UIView *) addnewViewatPoint:(NSSet *)touches withEvent:event
 {

UIView *backgroundView=[[[UIView alloc] initWithFrame: CGRectMake(10.0, 30.0, 200.0, 25.0)] autorelease];
[backgroundView setBackgroundColor:[UIColor redColor]];
[backgroundView setUserInteractionEnabled:NO];
backgroundView.tag=101;
return backgroundView;
 }


 - (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event
   {
if ([self supportsSwipingForCellAtPoint:gestureStartPoint])
{
    TISwipeableTableViewCell * cell = (TISwipeableTableViewCell *)[self cellForRowAtIndexPath:[self indexPathForRowAtPoint:gestureStartPoint]];
    if(isTouchesMoved==NO)
    {
        [self.delegate tableView:self didSelectRowAtIndexPath:[self indexPathForCell:cell]];
        [self touchesCancelled:touches withEvent:event];
    }

    [UIView beginAnimations:nil context:NULL];
    if(isTouchesMoved==YES)
    {
        [cell setFrame:prevLoc];
        [tempView setFrame:prevLocBack];
        isTouchesMoved=NO;
    }
    moved=TRUE;
    [UIView commitAnimations];
    [self touchesCancelled:touches withEvent:event];
    //[super touchesEnded:touches withEvent:event];
}
else
{
    [super touchesEnded:touches withEvent:event];
}

}

你能否在表格下方的视图中添加需要静止的uiview？

保持子视图静止，而superview正在移动
