Answer 1

It seems Up NSURLSessionUploadTask does not support Large size NSData, But you can give a file path to NSURLSessionUploadTask to upload on server, or write your image temporary on disk firs then give path.

Here's an example it is uploading both the filepath and NSdata.

Uploads using backgroundSessionConfiguration and NSURLSessionUploadTask cause app to crash

Updated :

//Create a file to upload
UIImage *image = [UIImage imageNamed:@"onboarding-4@2x.png"];
NSData *imageData = UIImagePNGRepresentation(image);
NSFileManager *fileManager = [NSFileManager defaultManager];
NSArray *URLs = [fileManager URLsForDirectory:NSDocumentDirectory inDomains:NSUserDomainMask];
NSString *documentsDirectory = [[URLs objectAtIndex:0] absoluteString];

// Here's the filePath URL

NSString *filePath = [documentsDirectory stringByAppendingString:@"testfile.png"];
[imageData writeToFile:filePath atomically:YES];
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL:[NSURL URLWithString:@"https://file.upload/destination"]];
[request setHTTPMethod:@"PUT"];

// Here it is using it filePath.

NSURLSessionUploadTask *uploadTask = [upLoadSession uploadTaskWithRequest:request fromFile:[NSURL URLWithString:filePath] completionHandler:^(NSData *data, NSURLResponse *response, NSError *error) {
    //code
}];
