  1. Add a variable in your class to save the index of current string
  2. Write a method which increase the index and update the label with the next string
  3. Create a NSTimer with interval = 60 seconds to call this method repeatly

Update

Per your comments I guess what you want to update is the location info? Some references:

use NSTimer with 60 sec interval, write a method to get the text from the array and display it in the label.

Use an NSTimer 

NSTimer *timer = [NSTimer scheduledTimerWithTimeInterval:60.0 target:self selector:@selector(changeText:) userInfo:nil repeats:YES];

Remember to use [timer invalidate] if you want to stop the timer, or you'll have a crash if the target has been released.
