UITextField text field does not set

Question

I'm trying to update the username field for a textfield. Currently there is a place holder which has "Username" written in it. I am loading the username from a settings file but for clarity I will just hardcode in the username.

- (void)viewDidLoad {
    settings=[Settings new];
    [settings loadData];

    //username.text=settings.username;
    username.text=@"Test";
}

For some reason this does not work!!! However, if I have a button which when I click it, that will update the textfield.

e.g.

- (IBAction)login:(id)sender{
    username.text=@"test";
}

So the button updates the text but I cannot update from viewDidLoad. Is this a threading issue? I can't believe something so simple is taking so long.

Answer 1

The controls are probably not created at this point.

Try setting the value in - (void)viewDidAppear:(BOOL)animated in your ViewController.

You might also want to try - (void)viewWillAppear:(BOOL)animated as well.

Answer 2

i don't know why, but you're only able to change the text of a textfield AFTER it was initially displayed

=> use "- (void)viewDidAppear:(BOOL)animated"

this will work

Answer 3

You've declared the text field as an IBOutlet within a property. The mistake I did was that I forgot to connect the Outlets (text fields) to my File's Owner in Interface Builder.
