ios - UIImageView 意外改变大小

Question

我有 UITableView ，其中的单元格上有图像。我使用 Storyboard，并将 UIImageView 连接为 socket 并将其命名为 imageView。我得到的图像大小不同(我通过 URL 下载)。但是，当表格显示时，有时图像显示的尺寸不正确(它应该是宽度和高度为 66x66 的正方形，但在许多情况下正方形更大，或者实际上宽度大于高度)。

显然我希望我的 UIImageView 的边框保持稳定。这是我的单元格代码:

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    static NSString *CellIdentifier = @"Cell";
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath];

    UILabel *labelText = (UILabel *)[cell viewWithTag:1000];
    labelText.text = [[self.listOfPlaceDetails objectAtIndex:indexPath.row] objectForKey:@"name"];

    if (cell == nil){
        cell = [[UITableViewCell alloc]initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
    }

    [cell.imageView setImageWithURL:[NSURL URLWithString:[[self.listOfPlaceDetails objectAtIndex:indexPath.row]objectForKey:@"imageFirst"]] placeholderImage:[UIImage imageNamed:@"dashie.png" ]completed:^(UIImage *image, NSError *error, SDImageCacheType cacheType){

        UIImage *resizedImage = [image resizedImageWithBounds:CGSizeMake(66, 66)];
        UITableViewCell *cell = [tableView cellForRowAtIndexPath:indexPath];


        cell.imageView.layer.cornerRadius = cell.imageView.bounds.size.width /2.0f;
        cell.imageView.clipsToBounds = YES;
        cell.separatorInset = UIEdgeInsetsMake(0, 82, 0, 0);

       cell.imageView.image = resizedImage ;


    }];




    cell.imageView.contentMode = UIViewContentModeScaleAspectFit;

return cell;
}

请解释一下发生了什么以及如何解决这个问题，任何建议将不胜感激，谢谢!

添加新的imageView并设置图像。我建议您创建 uitablviewCell 的子类并将 imageView 添加为导出 View

 - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
    {
        static NSString *CellIdentifier = @"Cell";
        UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath];

        UILabel *labelText = (UILabel *)[cell viewWithTag:1000];
        labelText.text = [[self.listOfPlaceDetails objectAtIndex:indexPath.row] objectForKey:@"name"];

        if (cell == nil){
            cell = [[UITableViewCell alloc]initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
        UIImageView *imgView = [[UIImageView alloc] initWithFrame:yourFrame];
        imgView.contentMode = UIViewContentModeScaleAspectFit;
        [cell addSubview:imgView];
        imgView.tag = 7;
        }

       UIImageView *img = (UIImageView*)[cell viewWithTag:7];
       UIImage *resizedImage = [image resizedImageWithBounds:CGSizeMake(66, 66)];
       img.imqge = resizedImage
