- (void) showActivity
{
NSAutoreleasePool * pool = [[NSAutoreleasePool alloc] init];

NSDateFormatter *formatter = [[[NSDateFormatter alloc] init] autorelease];
NSDate *date = [[[NSDate alloc] init] autorelease];

[formatter setTimeStyle:NSDateFormatterMediumStyle];

//change font size by orientation
int fontSize=90;
if([[UIDevice currentDevice] orientation]==UIInterfaceOrientationPortrait) fontSize=48;
clockLabel.font = [UIFont fontWithName:@"Helvetica" size:fontSize];

[clockLabel setText:[formatter stringFromDate:date]];

[pool release];
}

Add belove this codd
// This will produce a time that looks like “12:15:00 PM”.
[formatter setTimeStyle:NSDateFormatterMediumStyle];

//change font size by orientation
int fontSize=90;
if([[UIDevice currentDevice] orientation]==UIInterfaceOrientationPortrait) fontSize=48;
clockLabel.font = [UIFont fontWithName:@"Helvetica" size:fontSize];

Thanks!

// This starts the timer which fires the showActivity
// method every 0.5 seconds
myTicker = [NSTimer scheduledTimerWithTimeInterval: 0.5
target: self
selector: @selector(showActivity)
userInfo: nil
repeats: YES];

}

It gives me a build error that myTicker is undefined.

Can anyone help me?

I get tons of errors when I build and run. It may be because this was developed over a year ago or maybe because I don’t know what i’m doing. Let me know if you know something I don’t. Thanks so much :) Great tutorial.
