It is quite simple. You just need to set appropriate value of property progress of UIProgressView.

In delegate of NSURLConnection you should receive the amount of data you are waiting to download and update the progress during downloading. Progress is represented by a floating-point value between 0.0 and 1.0, inclusive, where 1.0 indicates the completion of the task.
