Need to pause and restart execution in loop

I want to move an icon around on the iPhone screen. I made an array of positions and one of ypositions. I get a random number and return a position from a function as xPosition, yPosition.

I figured I can change the x and y position of the UIImage in a loop. If I were to execute the loop, I'm sure the computer would run so fast I would only actually see the last position. I need to pause for a second before changing the x and y position of the icon so it appears to jump around on the screen. I'm not sure how to do that.

If there is a better way to do what I am trying to do, I would certainly like to know. Thanks

The fast way to accomplish this task would be to use the C sleep function, but the likely safer and more object-oriented way to do this would be to use NSTimer
