kết quả Swift/SKStoreProductViewController pushViewController trong (LLĐB)

Để đẩy người dùng đến cửa hàng iTunes cho các hạng mục mong muốn Tôi đang sử dụng các chức năng sau:kết quả Swift/SKStoreProductViewController pushViewController trong (LLĐB)

func openStoreProductWithiTunesItemIdentifier(identifier: String) { 

    let storeViewController = SKStoreProductViewController() 
    storeViewController.delegate = self 

    let parameters = [ SKStoreProductParameterITunesItemIdentifier : identifier, SKStoreProductParameterAffiliateToken : ITUNES_AFFILIATE_ID] 
    storeViewController.loadProductWithParameters(parameters) { [weak self] (loaded, error) -> Void in 
     if loaded { 

      self!.navigationController?.pushViewControllerWithHandler(storeViewController, animated: true) { 

       LilithProgressHUD.hide() // custom progress hud 
      } 
     } 
    } 
} 

extension UINavigationController { 

    func pushViewControllerWithHandler(viewController: UIViewController, animated: Bool, completion: Void -> Void) { 

     CATransaction.begin() 
     CATransaction.setCompletionBlock(completion) 
     pushViewController(viewController, animated: animated) 
     CATransaction.commit() 
    } 
}

gọi bởi

let trackID = "thisIsMyTrackID" 
openStoreProductWithiTunesItemIdentifier(trackID)

Điều này dẫn đến

Nếu tôi thay vì:

self!.navigationController?.pushViewControllerWithHandler(storeViewController, animated: true) { 

      LilithProgressHUD.hide() // custom progress hud 
     }

Sử dụng:

self?.presentViewController(storeViewController, animated: true, completion: { 
      LilithProgressHUD.hide() // custom progress hud 
     })

, nó đang làm việc. Nhưng tôi cần bộ điều khiển để đẩy trong phạm vi navigationController để vừa với phần còn lại của chế độ xem và hoạt ảnh. Tôi đang thiếu gì? Trợ giúp rất được đánh giá cao.

Bạn có thiết lập điểm ngắt không? Backtrace là gì? Khi bạn nhấn '(lldb)' gõ 'bt all' và đăng kết quả. – JAL

tôi đã đặt điểm ngắt ngoại lệ và nó dừng trên các dòng được đăng dưới dạng màn hình. tôi cũng đã đăng backtrace cho bạn. cảm ơn bạn rất nhiều vì nỗ lực của bạn –

Trường hợp ngoại lệ và dấu vết ngăn xếp cho bạn biết rằng bộ điều khiển lưu trữ xem là không hài lòng về việc bị đẩy vào một chồng nav . Thử nghiệm của bạn cho thấy nó là hạnh phúc được trình bày. Từ các tài liệu:

giới thiệu bộ điều khiển xem modally từ một bộ điều khiển xem trong ứng dụng của bạn

Vì vậy, bạn nên trình bày nó modally.

Trong khi có thể bạn có thể làm cho nó hoạt động theo một cách khác, nó có khả năng phá vỡ trong tương lai nếu bạn không tuân theo các nguyên tắc (bất tiện).

cảm ơn bạn rất nhiều vì phân tích này và trích dẫn từ các tài liệu. tôi đã hy vọng cho một lựa chọn khác, nhưng sau đó tôi đoán có chỉ đơn giản là không có ... –

cảm ơn bạn một lần nữa để được giúp đỡ của bạn. tôi đã trao tiền thưởng cho bạn –
