使用DLImageLoader iOS

有没有人能帮我把这些结合起来

下面是我的代码。。。我不理解，因为我的图像是从核心数据中的NSString而不是URL加载的（可能我无法使用此帮助文件）

我的代码是：

SCTableViewSection *Section3 = [self.tableViewModel sectionAtIndex:0];
    Section3.cellActions.lazyLoad = ^(SCTableViewCell *cell, NSIndexPath *indexPath)

    {

        DLImageView *imageView = (DLImageView *)[cell viewWithTag:1];
        NSString *imageString = (NSString *)[cell.boundObject valueForKey:@"thumbnail"];
        NSString *fullName = [NSString stringWithFormat:@"Documents/%@", imageString];
        NSString *imagePath = [NSHomeDirectory() stringByAppendingPathComponent:fullName];
        UIImage *originalImage = [UIImage imageWithContentsOfFile:imagePath];
        NSLog(@"added image from lazyload");

        // size of actual thumbnail to display in cell
        CGSize destinationSize = CGSizeMake(154,95); // size of actual thumbnail
        UIGraphicsBeginImageContext(destinationSize);
        [originalImage drawInRect:CGRectMake(0,0,destinationSize.width,destinationSize.height)];
        UIImage *thumbnail = UIGraphicsGetImageFromCurrentImageContext();

        UIGraphicsEndImageContext();

        [UIView transitionWithView:imageView
                          duration:2.25f
                           options:UIViewAnimationOptionTransitionCrossDissolve
                        animations:^{
                            imageView.image = thumbnail;
                        } completion:nil];

    };

这一行中是否有图像->UIImage*originalImage=[UIImage imageWithContentsOfFile:imagePath]？并尝试使用[imageView setNeedsDisplay]；在imageView.image=缩略图之后。
