UITableView Cell中的图像太大了

Question

我在用:

NSString *thearticleImage = entry.articleImage;
    NSRegularExpression *expression = [NSRegularExpression regularExpressionWithPattern:@"(?i)\\b((?:[a-z][\\w-]+:(?:/{1,3}|[a-z0-9%])|www\\d{0,3}[.]|[a-z0-9.\\-]+[.][a-z]{2,4}/)(?:[^\\s()<>]+|\\(([^\\s()<>]+|(\\([^\\s()<>]+\\)))*\\))+(?:\\(([^\\s()<>]+|(\\([^\\s()<>]+\\)))*\\)|[^\\s`!()\\[\\]{};:'\".,<>?«»“”‘’]))" options:NSRegularExpressionCaseInsensitive error:NULL];
    NSString *someString = thearticleImage;
    self.theurl = [someString substringWithRange:[expression rangeOfFirstMatchInString:someString options:NSMatchingCompleted range:NSMakeRange(0, [someString length])]];
    NSURL *picimage = [NSURL URLWithString:theurl];



    NSData * urlData = [NSData dataWithContentsOfURL: picimage];
    UIImage * imageweb = [UIImage imageWithData: urlData];

    cell.imageView.frame = CGRectMake(0, 0, 70, 70);
    cell.imageView.image = imageweb;

问题是这会占用整个单元格,我不确定为什么它不只是在左侧.

我的表格细胞图像遇到了类似的问题.我使用以下内容来缩放图像:

UIImage *imageOne = [UIImage imageNamed:[imagesArray objectAtIndex:indexPath.row]];

cell.imageView.image = [UIImage imageWithCGImage:imageOne.CGImage scale:imageOne.size.width/40 orientation:imageOne.imageOrientation];

注意:考虑上面的"40"表示您希望图像有多少像素宽.
