Ribbit

The Ribbit app crashed when I clicked the send button in the Camera View Controller. The output said

Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'Can't use nil for keys or values on PFObject. User NSNull for values.'

- (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 video or photo to share" delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil];

        [alertView show];
        [self presentViewController:self.imagePicker animated:NO completion:nil];


      }
    else {
        [self uploadMessage];
        [self reset];

        [self.tabBarController setSelectedIndex:0];
    }

remove [self reset]; from the else condition

and make sure you have extra closing bracket at the end

you are missing one in the code you posted should look like this:

- (IBAction)send:(id)sender {

    if(self.image==nil &&[self.videoFilePath length]==0){
        UIAlertView *alertView=[[UIAlertView alloc]initWithTitle:@"Try again!" message:@"Please capture or select picture or video" delegate:self cancelButtonTitle:@"OK" otherButtonTitles: nil];
        [alertView show];
        [self presentViewController:self.imagepicker animated:NO completion:nil];
    }
    else{
        [self uploadMessage];

        [self.tabBarController setSelectedIndex:0];
    }

}

I am having the exact same problem outlined by Elizabeth/ What was stated above by Miles unfortunately didn't help as i already had deleted [self reset]; long ago.. What is the issue here?

  • (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];

    [alertView show];
[self presentViewController:self.imagePicker animated:NO completion:nil];

    } else { [self uploadMessage];

    [self.tabBarController setSelectedIndex:0];

    } }
