Question

I’m making my own web browser for the iPad, and I have a problem while I’m trying to make the history. Here’s the code:

.m
-(void)viewDidLoad{
[self historyMethod];
//more settings...
}

-(void)historyMethod{
NSString *googleString= @"http://www.google.es";
    NSString *currentURLString=TextField.text;
    [historyArray addObject:googleString];
    if ([googleString isEqual: currentURLString]) {
        googleString = nil;
        [TableView reloadData];
    }


    [historyArray addObject: currentURLString ];
    [TableView reloadData];

}

The problem that I have is that the historyMethod is executed just one time, and I need it working all the time! Since I’m a newbie, I don’t know too much about methods, and how I can make it work well. I tried it with a while loop but it didn’t work. Please help me people!

Answer 1

You mean you want the method to be called repeatedly?
you can use something like NSTimer to repeat a method call;

[NSTimer scheduledTimerWithTimeInterval:1.0 target:self selector:@selector(historyMethod) userInfo:nil repeats:YES];

This will call your method every 1 seconds, place this in your viewDidLoad method, instead of calling your historyMethod.

However, if you don’t understand methods, I’d recommend some looking for some Objective-C tutorials.
