I think it's Helpful for you...

- (void)sendImageToServer
{
    UIImage *yourImage= [UIImage imageNamed:@"image.png"];
    NSData *imageData = UIImagePNGRepresentation(yourImage);
    NSString *base64 = [imageData base64EncodedStringWithOptions:NSDataBase64Encoding64CharacterLineLength];
    NSString *strImage = [NSString stringWithFormat:@"data:image/png;base64,%@",base64];

    NSMutableDictionary *dic = [[NSMutableDictionary alloc] initWithObjectsAndKeys:strImage,@"image", nil];
    NSError * err;
    NSData *jsonData = [NSJSONSerialization dataWithJSONObject:dic options:0 error:&err];
    NSString *UserProfileInRequest = [[NSString alloc] initWithData:jsonData encoding:NSUTF8StringEncoding];
    NSData *data=[UserProfileInRequest dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES];
    NSString *len = [NSString stringWithFormat:@"%ld", (unsigned long)[data length]];

    // Init the URLRequest

    NSMutableURLRequest *req = [[NSMutableURLRequest alloc] init];
    [req setURL:[NSURL URLWithString:@"http://YOUR_URL"]];
    [req setHTTPMethod:@"POST"];
    [req setValue:len forHTTPHeaderField:@"Content-Type"];
    [req setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];
    [req setValue:@"application/json" forHTTPHeaderField:@"Accept"];
    [req setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Content-Type"];
    [req setHTTPBody:data];

    NSURLSession *session = [NSURLSession sharedSession];
    [[session dataTaskWithRequest:req completionHandler:^(NSData *dt, NSURLResponse *response, NSError *err){
        //Response Data
        NSMutableDictionary *dic = [NSJSONSerialization JSONObjectWithData:dt options:kNilOptions error:&err];
        NSLog(@"%@", [dic description]);

    }]resume];
