ios - 使用 AFnetworking 上传图像没有任何响应

Question

这是问题所在：

1. 我想在完成从 imagepicker 中选择图像后立即上传图像。

2. 所以，我把我的代码放在 imagepicker 委托方法中使用 afnetworking 上传图像。

3. 但它没有任何反应。

   //set the imageview to current image after choosing
   profilePic.image = image;
   
   //dismiss the imagepicker
   [picker dismissModalViewControllerAnimated:YES];
   
   //start upload image code
   NSDictionary *params = [NSDictionary dictionaryWithObjectsAndKeys:
                           @"steventi1901", @"username",
                           UIImagePNGRepresentation(profilePic.image), @"profile_pic",
                           nil];
   
    AFHTTPClient *client = [[AFHTTPClient alloc] initWithBaseURL:updateProfile];
   NSData *imageToUpload = UIImagePNGRepresentation(profilePic.image);
   
   NSMutableURLRequest *request = [client multipartFormRequestWithMethod:@"PUT" path:@"" parameters:params
                                               constructingBodyWithBlock: ^(id <AFMultipartFormData>formData) {
       [formData appendPartWithFileData: imageToUpload name:@"file" fileName:@"temp.png" mimeType:@"image/png"];
       //NSLog(@"dalem");
   }];
   
   AFHTTPRequestOperation *operation = [[AFHTTPRequestOperation alloc] initWithRequest:request];
   
   [operation setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) {
       NSString *response = [operation responseString];
       NSLog(@"response: [%@]",response);
   
   } failure:^(AFHTTPRequestOperation *operation, NSError *error) {
   
       if([operation.response statusCode] == 403){
           NSLog(@"Upload Failed");
           return;
       }
       NSLog(@"error: %@", [operation error]);
   
   }];
   
   [operation start];
   //end upload image code
   

它真的没有任何反应，所以我不知道这个过程是失败还是成功。

使用 Afnetworking 上传图像的最佳和简单方法。

请使用下面的 AFNetworking。

pod 'AFNetworking', '~> 2.5.4'

//Create manager

    AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];

    //parameters if any
    NSMutableDictionary *AddPost = [[NSMutableDictionary alloc]init];

    [AddPost setValue:@"Addparma" forKey:@"param"];

    NSString * url = [NSString stringWithFormat:@"www.addyourmainurl.com"];;    

    NSLog(@"AddPost %@",AddPost);

    [manager POST:url parameters:[AddPost copy] constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {

        //add image data one by one

        for(int i=0; i<[Array count];i++)
        {
            UIImage *eachImage  = [Array objectAtIndex:i];

            NSData *imageData = UIImageJPEGRepresentation(eachImage,0.5);

            [formData appendPartWithFileData:imageData name:[NSString stringWithFormat:@"image%d",i] fileName:[NSString stringWithFormat:@"image%d.jpg",i ] mimeType:@"image/jpeg"];

        }  

    } success:^(AFHTTPRequestOperation *operation, id responseObject) {

        NSLog(@"Success: %@", responseObject);

    } failure:^(AFHTTPRequestOperation *operation, NSError *error) {

        NSLog(@"Error: %@", error);

    }];

你设置了选择器的代表吗？

[yourPicker setDelegate:self]
