UILabeltext not changing !!!!

[pragyanshis]

I have defined a function in appdelegate like below.

- (void) ChangeLabelTextNSString *)SenderP
{
TeenTaalViewControllerM = [[TeenTaalViewController alloc] initWithNibName"TeenTaalViewController" bundle:nil];
TeenTaalViewControllerM.view.hidden= NO;
[self.TeenTaalViewControllerM.lblLoopCountM setText:SenderP];
self.TeenTaalViewControllerM.lblLoopCountM.hidden = NO;
}

and I am calling this function from a class like below

TeenTaalAppDelegate * TheAppDelegateL = [[UIApplication sharedApplication] delegate];
[TheAppDelegateL ChangeLabelText"Test"];



But the text of the UIlabel is not changing anyway !!!!please help !!!
