Question

I am trying to display some text in a label via the following code:

if (thisPhoto.userBio != NULL)
{
   thisUserBioLabel.text = [NSString stringWithFormat:@"%@",thisPhoto.userBio];
} 
else
{
   thisUserBioLabel.text = @"";                
}

However, I am having difficulty in removing the display if the value for thisPhoto.userBio is equal to NULL. I tried to print the value using NSLog(@"%@", thisPhoto.userBio) and I am getting the value <null>. How can I amend my code above such that I will not display the message if the value is <null>?

Answer 1

<null> is what happens when the value is NSNull not nil. To do this you need to add an extra check to your first if.

if (thisPhoto.userBio && ![thisPhoto.userBio isEqual:[NSNull null]])

That will check for both cases.
