Question

Why won’t the UILabel: “lbl” update on the iPhone?

…
from within a method:

myTimer =[NSTimer scheduledTimerWithTimeInterval:1.0 target:self selector:@selector(displayDataTimer) userInfo:nil repeats:YES];

…

-(void) displayDataTimer{

    NSString *temp = [textField1 text];

    [lbl setText:[NSString stringWithFormat:@"%d  %d", j, genValue]];

    //[self.view setNeedsDisplay:YES];    

    j++;
}

thx

Make sure your method is firing and you have set an Outlet to that label (named lbl) and that it is wired up and then:

self.lbl.text = [NSString stringWithFormat:@"%d  %d", j, genValue];
