AQGridView信元数据重复问题

Question

我正在尝试实现一个3Xn网格视图，目前我使用的是AQGridView类，它运行良好，但唯一的问题是，在像tableView这样的数据重复滚动时，在tableView中，我使用以下代码来处理这个问题

NSUInteger row = 0; 
NSUInteger sect = indexPath.section;

for (NSUInteger i = 0; i < sect; ++ i)
    row += [self tableView:tableView numberOfRowsInSection:i];

row += indexPath.row;

我想知道是否也有类似的解决方案。这是我当前的网格视图代码。

- (AQGridView *) gridView {

    if (![self isViewLoaded])
        return nil;

    AQGridView * const gv = (AQGridView *)_groupGridView;
    NSCParameterAssert([gv isKindOfClass:[AQGridView class]]);

    return gv;

}

- (BOOL) shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{

    return (interfaceOrientation != UIInterfaceOrientationPortraitUpsideDown);

}


- (NSUInteger) numberOfItemsInGridView: (AQGridView *) gridView
{

    return [selectedList count];

}

- (AQGridViewCell *) gridView:(AQGridView *)gridView cellForItemAtIndex:(NSUInteger)index {

    static NSString * const identifier = @"Cell";
    NTGridViewCell *cell = (NTGridViewCell *)[gridView dequeueReusableCellWithIdentifier:identifier];

    if (cell)
        NSCParameterAssert([cell isKindOfClass:[NTGridViewCell class]]);

    if (!cell) {

        CGRect cellFrame = (CGRect){
            CGPointZero,
            gridView.gridCellSize
        };

        cell = [NTGridViewCell cellFromNib];
        cell.reuseIdentifier = identifier;
        cell.frame = cellFrame;
        cell.delegate=self;

        cell.userName.text=[[selectedList objectAtIndex:index] valueForKey:@"name"];

        NSLog(@"number:%d,name:%@",index,[[selectedList objectAtIndex:index] valueForKey:@"name"]);

        cell.contentView.superview.backgroundColor=[UIColor clearColor];

    return cell;

}

我的selectedList中有26项，但是日志只打印最多11项，不管我滚动了多少，12项之后的标签从一开始就重复了。有什么建议吗？

试试这个..。

-(AQGridViewCell *) gridView:(AQGridView *)gridView cellForItemAtIndex:(NSUInteger)index
{
        static NSString * const identifier = @"Cell";
        NTGridViewCell *cell = (NTGridViewCell *)[gridView dequeueReusableCellWithIdentifier:identifier];

        if (cell)
            NSCParameterAssert([cell isKindOfClass:[NTGridViewCell class]]);

        if (!cell)
        {
            CGRect cellFrame = (CGRect){
                CGPointZero,
                gridView.gridCellSize
            };
            cell = [NTGridViewCell cellFromNib];
            cell.reuseIdentifier = identifier;
            cell.frame = cellFrame;
            cell.delegate=self;
        }
        cell.userName.text=[[selectedList objectAtIndex:index] valueForKey:@"name"];
        NSLog(@"number:%d,name:%@",index,[[selectedList objectAtIndex:index] valueForKey:@"name"]);
        cell.contentView.superview.backgroundColor=[UIColor clearColor];

        return cell;
}
