Question

I am having a label and an array which consists of 10 string values.I know how to display the text in that label.But now,For every 1 minutes I want to display each and every string from that array to the label .Any idea how to do this ?

Answer 1

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:
