    if (imageData!=nil) 
    [formData appendPartWithFileData:imageData name:@"file" fileName:@"image.png" mimeType:@"image/png"]; 


    if (audioData!=nil) 
    [formData appendPartWithFileData:audioData name:@"file" fileName:@"Audio.m4a" mimeType:@"audio/.mp4 .m4a"];

Answer 2

Set bool selon votre demande

-(void)uploadphoto{ 

    BOOL isImgData = YES; //set according to avaibility 
    BOOL isVoiceData = YES;//set according to avaibility 

    NSString* mid= @"1"; 
     NSString*userid=@"13"; //[[NSUserDefaults standardUserDefaults] valueForKey:kUserID]; 

     imageData = UIImagePNGRepresentation (thumbnail.image); 

     AFHTTPRequestOperationManager *manager = [[AFHTTPRequestOperationManager alloc] initWithBaseURL:[NSURL URLWithString:baseURLString]]; 

     NSDictionary *parameters = @{@"UserID":userid, @"Name": name_TF.text,@"MandalID":mid,@"Address":address_TV.text,@"PinCode":pincode_TF.text,@"Email":emailid_TF.text,@"Dese":grivence_TV.text}; 

     AFHTTPRequestOperation *op = [manager POST:@"Grievance/CreateRequest" parameters:parameters constructingBodyWithBlock:^(id<AFMultipartFormData> formData) { 

    if(isImgData){ 

     [formData appendPartWithFileData:imageData name:@"file" fileName:@"image.png" mimeType:@"image/png"]; 
    } 

    if(isVoiceData){ 

     [formData appendPartWithFileData:audioData name:@"file" fileName:@"Audio.m4a" mimeType:@"audio/.mp4 .m4a"]; 

    } 
     } success:^(AFHTTPRequestOperation *operation, id responseObject) { 
      NSLog(@"Success: %@ ***** %@", operation.responseString, responseObject); 

     } failure:^(AFHTTPRequestOperation *operation, NSError *error) { 
      NSLog(@"Error: %@ ***** %@", operation.responseString, error); 
     }]; 
     [op start]; 

     } 
}
