Below is the code snippet which would help in uploading multiple Images along with Text to Server: -(void)uploadMultipleImagesWithTextMessageUsingAFNetworkingMultipartFormat:(id)sender {     // Upload multiple images to server using multipartformatdata (AFNetworking)         NSString *stringMessage = @"I am uploading multiple images to server";           AFHTTPClient *client = [[AFHTTPClient alloc] initWithBaseURL: [NSURL URLWithString:BASEURL]]; // replace BASEURL     client.parameterEncoding = AFJSONParameterEncoding;     NSMutableURLRequest *request = [client multipartFormRequestWithMethod:@"POST" path:@"/PostMultImagesWithTextAPI" parameters:nil constructingBodyWithBlock: ^(id <AFMultipartFormData>formData) {                 [formData appendPartWithFormData:[[[NSUserDefaults standardUserDefaults] objectForKey:KServerAccessToken] dataUsingEncoding:NSU...
