I am a noobie and trying to understand the code posted...I think I have a good handle on your code. the thing I don't understand is:
[appDelegate setModelData:x]
Why did it replace [someUILabel setText:joke]?
Is it necessary to use Delegate to work? I am building my own exercise with a label and a button..so that when a button is pushed..a random line will be displayed in the UIlabel.
