Force Reload Table View

All,

How would I force reload a table view (within a view controller) every five seconds for fifteen se开发者_运维百科conds when a button is pressed?

Thanks, James

First you create a timer when you press your button,

NSTimer *timer = [NSTimer scheduledTimerWithTimeInterval:5.0 target:self selector:@selector(updateMethod) userInfo:nil repeats:YES];

Then in your method that fires every 5 seconds

- (void) updateMethod
{
   [self.tableView reloadData];
}

Check out NSTimers & Apple Documentation. This will give you a concept about intervals and help you with the delay you are looking for.

And for reloading tableview, [self.tableView reloadData]; should to the trick.
