Question

I have UITextField named textField where user can save phone number with NSUserDefaults. Then I have IBAction to call that number. How can I put to that action a number what user have been saved to UITextField?

-(IBAction)callPhone:(id)sender {
    [[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"tel:123456"]];
}

UPDATE

- (IBAction) saveBtnPresssed : (id) sender
{
    myString1 = [[NSString alloc] initWithFormat:textField.text];
    [textField setText:myString1];
    NSUserDefaults *stringDefault = [NSUserDefaults standardUserDefaults];
    [stringDefault setObject:myString1 forKey:@"stringKey"];
}


- (void)viewDidLoad
{
    [textField setText:[[NSUserDefaults standardUserDefaults] objectForKey:@"stringKey"]];
    [super viewDidLoad];
}

Answer 1

The string you are looking for is returned by:

[textField text];

If you saved that to user defaults then you can just:

-(IBAction)callPhone:(id)sender {
NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
NSString *phoneNumberString = [defaults objectForKey:@"key_you_saved_the_number_with"];

//... do what you need with that number here

}

EDIT:

    [NSURL URLWithString:[NSString stringWithFormat:@"tel:%@"], [defaults objectForKey:@"stringKey"]];

so the resulting string should be “tel:” + the actual number from the text field instead of “tel:123456”
