Share Extension not uploading full size images

Question

i am developeing share extension for my iOS application. i had really done every thing but the problem is that my code is only working for small images but when i upload image taken from device camer then uploading fails and only text get uploded.

- (void)performUploadWith:(NSDictionary *)parameters imageFile:(UIImage *)image{

NSString *boundary = @"SportuondoFormBoundary";


//    NSURLSessionConfiguration *configuration= [NSURLSessionConfiguration backgroundSessionConfigurationWithIdentifier:configurationName];

//    NSURLSession *session=[NSURLSession sessionWithConfiguration:configuration delegate:self delegateQueue:nil];
//    NSMutableURLRequest *request;//[NSURLRequest pho]

NSURLSessionConfiguration *configuration = [NSURLSessionConfiguration defaultSessionConfiguration];
configuration.HTTPAdditionalHeaders = @{
                                        @"api-key"       : @"55e76dc4bbae25b066cb",
                                        @"Accept"        : @"application/json",
                                        @"Content-Type"  : [NSString stringWithFormat:@"multipart/form-data; boundary=%@", boundary]
                                        };

NSURLSession *session=[NSURLSession sessionWithConfiguration:configuration delegate:self delegateQueue:nil];


NSMutableData *body = [NSMutableData data];


for (NSString *key in parameters)
{
    [body appendData:[[NSString stringWithFormat:@"--%@\r\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]];
    [body appendData:[[NSString stringWithFormat:@"Content-Disposition: form-data; name=\"%@\"\r\n\r\n", key] dataUsingEncoding:NSUTF8StringEncoding]];
    [body appendData:[[NSString stringWithFormat:@"%@\r\n", [parameters objectForKey:key]] dataUsingEncoding:NSUTF8StringEncoding]];

}

NSData *imageData = UIImageJPEGRepresentation(image, 0.8);
NSLog(@"imageDATE, %@", imageData);
if (imageData)
{
    [body appendData:[[NSString stringWithFormat:@"--%@\r\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]];
    [body appendData:[[NSString stringWithFormat:@"Content-Disposition: form-data; name=\"%@\"; filename=\"image.jpg\"\r\n", @"file"] dataUsingEncoding:NSUTF8StringEncoding]];
    [body appendData:[@"Content-Type: image/jpg\r\n\r\n" dataUsingEncoding:NSUTF8StringEncoding]];
    [body appendData:imageData];
    [body appendData:[[NSString stringWithFormat:@"\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];
}
[body appendData:[[NSString stringWithFormat:@"--%@--\r\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]];




// Data uploading task. We could use NSURLSessionUploadTask instead of NSURLSessionDataTask if we needed to support uploads in the background
NSURL *url = [NSURL URLWithString:[NSString stringWithFormat:@"%@%@",kURLBase,kURLAddPostDL]];
NSLog(@"url %@",url);
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url cachePolicy:NSURLRequestReloadIgnoringCacheData timeoutInterval:10000];
request.HTTPMethod = @"POST";
request.HTTPBody = body;



NSURLSessionUploadTask *upload=[session uploadTaskWithRequest:request fromData:request.HTTPBody];
[upload resume];
}

---

i update my code to this and i check on server my request never reaches to server. I am using this code

        NSInteger randomNumber = arc4random() % 1000000;
    NSURLSessionConfiguration *config = [NSURLSessionConfiguration backgroundSessionConfigurationWithIdentifier:[NSString stringWithFormat:@"testSession.foo.%d", randomNumber]];
    config.sharedContainerIdentifier=kGroupNameToShareData;
  session = [NSURLSession sessionWithConfiguration:config delegate:self delegateQueue:nil];
  NSURLSessionUploadTask  *uploadTask = [session uploadTaskWithRequest:request fromFile:[NSURL        URLWithString:[NSString stringWithFormat:@"file://%@", dataSrcImagePath]]];

   [uploadTask resume];

Extensions aren't allowed their own cache disk space. Need to share with application

Uploading large image need cache disk space,so you upload failed.

You need create url session with following codes:

let configName = "com.shinobicontrols.ShareAlike.BackgroundSessionConfig"
let sessionConfig = NSURLSessionConfiguration.backgroundSessionConfigurationWithIdentifier(configName)
// Extensions aren't allowed their own cache disk space. Need to share with application
sessionConfig.sharedContainerIdentifier = "group.ShareAlike"
let session = NSURLSession(configuration: sessionConfig)

and then setting the app group both extension target and containing app.
