UIImageView+AFNetworking类别与UIActivityIndicatorView参考内存是否保留?

我正在尝试实现一个类别,以显示 UIImageView 从带有褪色和 UIActivityIndicatorView ,我在网上找到了一些东西,并在最终版本中进行了编辑:

UIImageView+AF网络负载.m

@implementation UIImageView (AFNetworkingLoad)

- (void)setImageWithURL:(NSURL *)url placeholderImage:(UIImage *)placeholderImage fadeInWithDuration:(CGFloat)duration withLoadIndicator:(UIActivityIndicatorView *)load_indicator {

    [load_indicator startAnimating];

    NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url];
    [request setHTTPShouldHandleCookies:NO];
    [request addValue:@"image/*" forHTTPHeaderField:@"Accept"];

    __weak typeof (self) weakSelf = self;

    [self setImageWithURLRequest:request placeholderImage:placeholderImage success:^(NSURLRequest *request, NSHTTPURLResponse *response, UIImage *image) {
        [load_indicator stopAnimating];
        if (!request) // image was cached
            [weakSelf setImage:image];
        else
            [UIView transitionWithView:weakSelf duration:duration options:UIViewAnimationOptionTransitionCrossDissolve animations:^{
                [weakSelf setImage:image];
            } completion:nil];
    } failure:^(NSURLRequest *request, NSHTTPURLResponse *response, NSError *error) {
        [load_indicator stopAnimating];
    }];
}

然后我用它来定制 UITableViewCell 以这种方式:

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
MyCell *cell = (MyCell *)[tableView dequeueReusableCellWithIdentifier:CellIdentifier];
...
[cell.img_view setImageWithURL:[NSURL URLWithString:my_url] placeholderImage:nil fadeInWithDuration:0.3 withLoadIndicator:cell.load_img];
...
}

所有的工作都很好,现在我的问题是,这个实现传递了UIActivityIndicatorView的引用,我是否会有一些内存泄漏?还是保留问题?显然我在iOS项目中使用ARC。。。
