The app will not retrieve messages

I have fixed this issue, but I would like to inform others about what happened Original Code:

CameraViewController.m 
- (IBAction)send:(id)sender {
    if (self.image == nil && [self.videoFilePath length] == 0) {
        UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"Try Again" message:@"Please capture or select a photo or video to share" delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil, nil];
        [alertView show];
        [self presentViewController:self.imagePicker animated:NO completion:nil];
    }
    else {
        [self uploadMessage];
        [self.tabBarController setSelectedIndex:0];
        [self reset];
        }
    }
}

My code:

CameraViewController.m 
- (IBAction)send:(id)sender {
    if (self.image == nil && [self.videoFilePath length] == 0) {
        UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"Try Again" message:@"Please capture or select a photo or video to share" delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil, nil];
        [alertView show];
        [self presentViewController:self.imagePicker animated:NO completion:nil];
    }
    else {
        [self uploadMessage];
        [self.tabBarController setSelectedIndex:0];
        if ([self.completed isEqualToString:@"YES"]) { //Added line
            [self reset];
        }
    }
}

Explanation of the added line: I created a string called "completed". If the value of the string is "YES", it would trigger the reset method. The error was that the recipients array would get reset before the message was uploaded.
