Updating data UITableView

whats the best way to refresh data in a UITableView, lets say data is populated at start-up then this data changes, how could i refresh the data, every 30 seconds or give the option of the user to refresh the data.

i can populate data but unsure on how to update the data when it has been put in the UITableView.

Use timer NSTimer to update you UITabelView after each 30 second.

Use NSTimer 

NSTimer* myTimer = [NSTimer scheduledTimerWithTimeInterval: 30.0 target: self
                                   selector: @selector(callAfterThirtySecond:) userInfo: nil repeats: YES];

After each 30.0 second , iOS will call the below function

Make isStopUdating as class member just like UITabelView instance : if you want to discontinue of updating table then set isStopUdating with YES,

-(void) callAfterThirtySecond:(NSTimer*) timer 
{

    if(isStopUdating)
    {
         [timer invalidate];
    } 
    [myTableView reloadData];

}

If You Update regularly means
Use This
NSTimer * timerFade = [NSTimer scheduledTimerWithTimeInterval:30.0 target:self selector:@selector(get) userInfo:nil repeats:YES];

and

`-(void) get
{
your url process

[self.tableview reload data];

}

if you give the option for user You may directly call

[self get];
