Question

我是Objective-cI我正在处理集合视图。在我的集合视图中，我的数组中包含数据列表。当我将数据从我的数组加载到集合单元格时，它没有按照数组顺序显示。当我滚动时，单元格值会不断变化。

这是我的代码。

- (NSInteger)collectionView:(UICollectionView *)collectionView numberOfItemsInSection:(NSInteger)section{
return myObject.count;
}

- (UIView *)collectionView:(UICollectionView *)collectionView cellForItemAtIndexPath:(NSIndexPath *)indexPath{
CollectionViewCell *cell = [collectionView dequeueReusableCellWithReuseIdentifier:@"CELL" forIndexPath:indexPath];
if([statusfield isEqualToString:@"13"])
{
    [cell.mySegmentedControl setTitle:@"SEND TO ADMIN" forSegmentAtIndex:0];
    [cell.mySegmentedControl setTitle:@"EVALUATE" forSegmentAtIndex:1];
}
else if([statusfield isEqualToString:@"5"])
{
    [cell.mySegmentedControl setEnabled:NO forSegmentAtIndex:0];
    [cell.mySegmentedControl setEnabled:NO forSegmentAtIndex:1];
}

else if([statusfield  isEqualToString: @"1"])
{
    [cell.mySegmentedControl setTitle:@"ACCEPT" forSegmentAtIndex:0];
    [cell.mySegmentedControl setTitle:@"REJECT" forSegmentAtIndex:1];
}
else if([statusfield isEqualToString:@"3"])
{
    [cell.mySegmentedControl setTitle:@"VIEW" forSegmentAtIndex:0];
    [cell.mySegmentedControl setSelectedSegmentIndex:UISegmentedControlNoSegment];
}
return cell;
}

分段控件值正在根据数组进行更新。当我滚动集合视图时，它的顺序正在发生变化。任何帮助都将不胜感激。

检查以下代码。它可能会帮助你

for (UIImageView *imgView in cell.subviews) {
    if ([imgView isKindOfClass:[UIImageView class]]) {
        [imgView removeFromSuperview];
    }
}

之后添加你的观点

UIImageView *segmentImageView = [[UIImageView alloc]initWithFrame:CGRectMake(0, 5, cell.frame.size.width - 10, cell.frame.size.height - 10)];
segmentImageView.image = [segmentControlArray objectAtIndex:indexPath.row];
segmentImageView.contentMode = UIViewContentModeScaleAspectFit;
[cell addSubview:segmentImageView];

停止在集合视图中重新加载
