POUpdate UIButton title after receiving reply from SKProductsRequest for showing in-app purchases price

Body
copied!<p>I'm trying to create two buttons whose label is initially set as a default value. The two buttons are managed by a popOverViewController, in which the viewDidLoad method initialise all the controls. I also have another method called addButtons that gets executed by the AppDelegate after receiving a valid response from Apple's servers containing products descriptions and prices.</p> <p>My problem is that I can't get the label updated with that method.</p> <p>My viewDidLoad method in the popOverViewController is:</p> <pre><code>- (void)viewDidLoad { [super viewDidLoad]; // Do any additional setup after loading the view. // Add a label to the popover's view controller. button = [UIButton buttonWithType:UIButtonTypeRoundedRect]; button2 = [UIButton buttonWithType:UIButtonTypeRoundedRect]; [button addTarget:self action:@selector(button1Week:) forControlEvents:UIControlEventTouchDown]; NSString *priceWeekly = [NSString stringWithFormat:@"weekly subscription"]; [button setTitle:priceWeekly forState:UIControlStateNormal]; button.frame = CGRectMake(0.0, 0.0, 200.0, 50.0); [button2 addTarget:self action:@selector(button1Month:) forControlEvents:UIControlEventTouchDown]; [button2 setTitle:@"monthly subscription" forState:UIControlStateNormal]; button2.frame = CGRectMake(0.0, 55.0, 200.0, 50.0); [self.view addSubview:button]; [self.view addSubview:button2]; } </code></pre> <p>and my update label method, of which I'm sure it gets called at the right time, is:</p> <pre><code>-(void)addButtons { [self.button setTitle:@"updated label" forState:UIControlStateNormal]; [self.button2 setTitle:@"updated label 2" forState:UIControlStateNormal]; } </code></pre> <p>can you please check my code and suggest the right way to update the labels? Basically I want to initialize the controls with a default label because of the waiting time between controls creation and server response.</p> <p>UPDATE:</p> <p>I have updated the code as follows, but still everything that's inside the addButtons method gets executed as I have an NSLog to check, but the button title still remains as created in viewdidload</p> <pre><code>- (void)viewDidLoad { [super viewDidLoad]; // Do any additional setup after loading the view. // Add a label to the popover's view controller. UIButton *button = [UIButton buttonWithType:UIButtonTypeRoundedRect]; UIButton *button2 = [UIButton buttonWithType:UIButtonTypeRoundedRect]; ilManifestoAppDelegate *delegate = (ilManifestoAppDelegate*)[[UIApplication sharedApplication] delegate]; [button addTarget:self action:@selector(button1Week:) forControlEvents:UIControlEventTouchDown]; // [button setTitle:priceWeekly forState:UIControlStateNormal]; button.frame = CGRectMake(0.0, 0.0, 200.0, 50.0); [button2 addTarget:self action:@selector(button1Month:) forControlEvents:UIControlEventTouchDown]; // [button2 setTitle:@"monthly subscription" forState:UIControlStateNormal]; button2.frame = CGRectMake(0.0, 55.0, 200.0, 50.0); // [self addButtons]; NSString *weekPrice = [NSString stringWithFormat:@"settimanale a %@",delegate.priceWeek]; [button setTitle:weekPrice forState:UIControlStateNormal]; [button2 setTitle:@"updated label 2" forState:UIControlStateNormal]; NSLog(@"week price %@", weekPrice); [self.view addSubview:button]; [self.view addSubview:button2]; } -(void)addButtons { UIButton *button = [UIButton buttonWithType:UIButtonTypeInfoDark]; [button setTitle:@"modificato" forState:UIControlStateNormal]; [self.view addSubview:button]; NSLog(@"addButtons executed"); } </code></pre>
