appStoreReceiptURL Error

问题

I can't understand why it does not enter into the if control. Anyone knows explain to me?

- (void)verifyapp{
    NSURL *receiptURL = [[NSBundle mainBundle] appStoreReceiptURL];

    NSLog(@"%@", receiptURL);
    //CONTROLLO SE ESISTE

    if ([[NSFileManager defaultManager] fileExistsAtPath:receiptURL.path]) {

    }
}

Receipt only exist if you install app from the AppStore. If you install it from the XCode Debug mode, it will not have a receipt. To debug your code you need to install app from AppStore first, launch it and install app from XCode above it.
