AFNetworking:setImageWithURLRequest没有设置图像

Question

我正在尝试在tableViewCell 上ImageView使用AFNetworking 设置图像setImageWithURLRequest.如果我不在方法中包含success和failure块,如下所示:

[cell.thumbnailImageView setImageWithURL:url placeholderImage:nil]; 

一切都很完美,图像设置.不幸的是我需要块.

这是我目前所拥有的cellForRowAtIndexPath:

if (self.images) { //check if the array of images is set, fetched from a URL

        NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString: [[self.images objectAtIndex:indexPath.row] objectForKey:@"tbUrl"]]];

        [cell.thumbnailImageView setImageWithURLRequest:request placeholderImage:[UIImage imageNamed:@"placeholder"] success:^(NSURLRequest *request, NSHTTPURLResponse *response, UIImage *image) {
                NSLog(@"success"); //it always lands here! But nothing happens
        } failure:^(NSURLRequest *request, NSHTTPURLResponse *response, NSError *error) {
                NSLog(@"fail");
        }];

    }

来自UIImageView+AFNetworking.h:

如果指定了成功块,则块的责任是在返回之前设置图像视图的图像.

在您的成功区块中,您需要说:

[cell.thumbnailImageView setImage: image]
