NSTimer Question

[rTicker]

How would I do this:

timer = [NSTimer scheduledTimerWithTimeInterval:TextField target:self selector:@selector (Over) userInfo:nil repeats:NO];

[kapps11]

timer = [NSTimer scheduledTimerWithTimeInterval:[textField.text intValue] target:self selector:@selector (Over:) userInfo:nil repeats:NO];

Thanks Kapps!

It works!

simulated in iOS4.1

My app takes RSS data and loads in a table.

If it loads once it's fine....BUT the problem starts when I use the NSTimer to autorefresh every 10 seconds, it closes the app and goes back to homescreen.

Any suggestions?

- (void)viewDidAppearBOOL)animated {
[super viewDidAppear:animated];

if([blogEntries count] == 0) {
[self refreshData];
}

reloadTimer = [NSTimer scheduledTimerWithTimeInterval:10 target:self selector:@selector(refreshData userinfo:nil repeats:YES];

}

- (void)refreshData{
NSString *blogAddress = @"http://twitter.com";
[self grabRSSFeed:blogAddress];
[blogTable reloadData];
}

- (void)viewWillDisappearBOOL)animated {
[reloadTimer invalidate], reloadTimer = nil;
}

The selector you added has a colon at the end, meaning it should take an argument. The method you defined, however, does not take an argument. When the run time cannot find a matching method, it crashes.

Hi Kelvin,

I took out the : and have this

selector:@selector(refreshData)

it is still closing the app...this line is the only problem...if i comment this line everything is fine.

If you read the documentation, you would find that the method must take an NSTimer as the argument.
