Ah, hmm. My programming book shows em in the property lines....
perhaps it doesnt matter as long as they're connected.
This line is wrong:
UILabel *StrikeCount = [[UILabel alloc] init];
Why are you Allocating a new label? You've already synthesized strikeCount so you can access like:
self.strikeCount.text =[NSString stringWithFormat
"%d", A]
EDIT:
Do an NSlog to make sure strikeCount.text has been changed. If the label display still doesn't change, than it has to be a connection issue.
Edit2/warning: I think by doing all of this in the appdelegate you'll run into problems, especially with the tabcontroller there.
Typically the appdelegate would manage the tabbarcontroller while additional view controllers would manage the content of the tabs. Idk, maybe you're doing something different, but if you haven't worked through books I figured I'd say it.
I dont have much experience myself, hope im still helping.
