Application crashes when loading multiple images from a server using AFNetworking

Question

I have included the AFNetworking library in my application for downloading images from a URL, and the application crashes when we upload multiple images.

When I analyze my code using the Xcode crash report list (Xcode → Window → Organizer → Crashes → Our app), it shows an error in the AFNetworking library for this line of code:

Class : UIImageView+AFNetworking

Method Name : setImageWithURLRequest

Line of code : [[[self class] af_sharedImageRequestOperationQueue] addOperation:self.af_imageRequestOperation];

Can someone help me deal with this issue?

Answer 1

Try using the following code

  NSURL *url = [NSURL URLWithString:@"YourImageURL"]; NSURLRequest *request = [NSURLRequest requestWithURL:url]; UIImage *placeholderImage = [UIImage imageNamed:@"placeholder"]; __weak UIImageView *weakImageView = yourImageView; [weakImageView setImageWithURLRequest:request placeholderImage:placeholderImage success:^(NSURLRequest *request, NSHTTPURLResponse *response, UIImage *image) { weakImageView.image = image; } failure:nil]; 

Answer 2

There are many unit tests for loading images and a new architecture in the 3.0.0 branch with additional tests covering loading multiple images.

Answer 3

https://github.com/Alamofire/Alamofire install this pod

Try using the following code to upload multiple images to the server code:

  Alamofire.upload( .POST, urlString, multipartFormData: { multipartFormData in for image in images { if let imageData = UIImageJPEGRepresentation(image, 0.1) { multipartFormData.appendBodyPart(data: imageData, name: "file", fileName: "file.jpeg", mimeType: "image/jpeg") } } }, encodingCompletion: { encodingResult in switch encodingResult { case .Success(let upload, _, _): upload.responseJSON(completionHandler: { (response) -> Void in if response.result.error != nil { print("Something is wrong while uploading images.") } else { } }) case .Failure(let encodingError): print(encodingError) } } )
