I ran my game. When I wanna go to the game store view controller in simulator, the app crashes. See the code:

.h

@property (weak, nonatomic) IBOutlet UILabel *coinLabel;
@property (weak, nonatomic) IBOutlet UILabel *itemLabel;

.m

int coin;
int itemQty;

- (IBAction)buy:(id)sender {
    coin = coin - 50;
    itemQty = itemQty + 1;
}
- (void)viewDidLoad {
    [super viewDidLoad];
    UILabel* itemLabel = [[UILabel alloc] init];
    itemLabel.text = [NSString stringWithFormat:@"%d", itemQty];

    UILabel* coinLabel = [[UILabel alloc] init];
    coinLabel.text = [NSString stringWithFormat:@"%d", coin];
}

... //I didn't edit anything here

Please help. Thanks

You're right and your answer helped me. The problem is on the linking of the outlets from UI to code. I deleted them and relink. But I met another crash when I used the StoreKit . It's also signal SIGABRT. I deleted the outlets and relink for many times but my app still crashes when I open the view controller of IAP. I got this in iTunes Connect in app purchase section " Your first In-App Purchase must be submitted with a new app version. Select it from the app’s In-App Purchases section and click Submit. Once your binary has been uploaded and your first In-App Purchase has been submitted for review, additional In-App Purchases can be submitted using the table below." And I have checked the product ID. Any solutions? Please help me. Thanks.
