Swift / SKStoreProductViewController PushViewController 结果为（lldb）

2024-03-27

为了将用户推送到 iTunes 商店获取所需的项目，我使用以下函数：

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()
    }
}

呼叫者

let trackID = "thisIsMyTrackID"
openStoreProductWithiTunesItemIdentifier(trackID)

这导致

如果我是：

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

            LilithProgressHUD.hide() // custom progress hud
        }

Using:

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

，这是工作。但我需要控制器来推动navigationController以适应其余的视图和动画。我缺少什么？非常感谢帮助。

异常和堆栈跟踪告诉您商店视图控制器不高兴被推入导航堆栈。您的测试表明它很高兴被呈现。从文档中：

所以，你应该以模态的方式呈现它。

虽然您可能可以通过其他方式使其工作，但如果您不遵循（不方便的）准则，将来可能会出现故障。
