从 iOS 审核过程中了解崩溃报告答案

【问题标题】：Understanding crash report from iOS review process从 iOS 审核过程中了解崩溃报告
【发布时间】：2019-10-22 10:22:47
【问题描述】：

我正在尝试将应用上传到 iOS App Store，但由于崩溃（我无法使用我拥有的多个模拟/设备重现）而遭到拒绝。

我在此附上崩溃报告。我遇到的问题是我无法正确地重新符号化崩溃，当我尝试右键单击并选择重新符号化它们时，我所能得到的只是：

我认为它崩溃的代码（WelcomeViewController.swift）

class WelcomeViewController: UIViewController {

    @IBOutlet weak var showsRoundMeButton: UIButton!

    @IBOutlet weak var showsByLocationBotton: UIButton!

    @IBOutlet weak var iosVersion: UILabel!
    override func viewDidLoad() {
        super.viewDidLoad()

        showsRoundMeButton.layer.cornerRadius = 10
        showsByLocationBotton.layer.cornerRadius = 10

        self.navigationController?.navigationBar.setBackgroundImage(UIImage(), for: UIBarMetrics.default)
        self.navigationController?.navigationBar.shadowImage = UIImage()
        self.navigationController?.navigationBar.isTranslucent = true
        self.navigationController?.navigationBar.backgroundColor = UIColor.clear

        iosVersion.text = version()

        BiAnalyticsService.logEvent("MainPage", withParameter: nil)

        // Do any additional setup after loading the view.
    }

    override var preferredStatusBarStyle : UIStatusBarStyle {
        return .lightContent
    }

    }

    func version() -> String {
        let dictionary = Bundle.main.infoDictionary!
        let version = dictionary["CFBundleShortVersionString"] as! String
        let build = dictionary["CFBundleVersion"] as! String
        return "v\(version) (\(build))"
    }

    @IBAction func searchShowsAroundMeButtonClicked(_ sender: UIButton) {
        BiAnalyticsService.logEvent("MainPage:searchShowsAroundMeButtonClicked", withParameter: nil)
        let vc:UITabBarController = (self.storyboard?.instantiateViewController(withIdentifier: "main")) as! UITabBarController
        vc.selectedIndex = 0

        self.present(vc, animated: true, completion: nil)
    }

    @IBAction func searchShowsByLocationButtonClicked(_ sender: UIButton) {
        BiAnalyticsService.logEvent("MainPage:searchShowsByLocationButtonClicked", withParameter: nil)
        let vc:UITabBarController = (self.storyboard?.instantiateViewController(withIdentifier: "main")) as! UITabBarController
        vc.selectedIndex = 1

        self.present(vc, animated: true, completion: nil)
    }

    /*
    // MARK: - Navigation

    // In a storyboard-based application, you will often want to do a little preparation before navigation
    override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
        // Get the new view controller using segue.destinationViewController.
        // Pass the selected object to the new view controller.
    }
    */

}

请注意，我已经清除了 BiAnalyticsService.logEvent... 因为我认为它可能会导致问题并且现在有代码：

    class func logEvent( eventName : String, withParameter : Dictionary<String,String>?){

//        if withParameter == nil {
//            mixpanel.track(eventName, properties:  staticProperties)
//        } else {
//            var prm = withParameter!
//            
//            for key in staticProperties.keys {
//                prm[key] = staticProperties[key]
//            }
//            mixpanel.track(eventName, properties: prm)
//        }



    }

任何帮助将不胜感激

【问题讨论】：

日志说您正在尝试使用已弃用的搜索控制器UISearchDisplayControllerNoLongerSupported，您是否在最新的 iOS 上对其进行了测试？
那么你的应用真的使用 UISearchDisplayController 吗？？？摆脱它并使用 UISearchController。
关注这个话题：stackoverflow.com/questions/57819165/…
看起来确实有 UISearchDisplayController（作为 iOS 开发中的 n00b，我没有注意到），问题是它在 13.1.3 上工作而没有崩溃，所以我不知道为什么会这样'不要在我的最后崩溃 --> 无论如何我已经设法从情节提要中删除它，我希望它能解决这个问题......

标签： ios swift crash

【解决方案1】：

在代码“searchdisplay”中查找，它将出现在 Storyboard 中某个旧视图控制器底部的某个位置，删除此 SearchDisplay 项，仅此而已。

在我的例子中，SearchDisplay 甚至链接到了 outlet（实际上并不存在真正的 outlet！也没有一个编译器错误！），很明显它已经很长时间没有使用了。崩溃仅在审核团队或通过 TestFlight 发生，而不是通过电缆在任何设备上发生。审查团队的崩溃报告什么也没说（象征性总是失败），因此我杀死了三天和三个构建，直到从测试人员那里得到有用的报告。

立即使用 TestFlight！在电缆上进行多次调试是不够的是时候了:-(

【解决方案2】：

从 iOS 13 和 iPad OS 13 开始，使用 Xcode 11 构建的应用无法使用 UISearchDisplayController。 UISearchDisplayController 从 iOS 8 开始被弃用，你应该使用 UISearchController

为了在本地重现这一点，您需要测试应用的精简变体

如果您收到其中一种崩溃但无法在本地重现，确保您正在 iOS 上测试应用的部署版本 13，通过使用 TestFlight 或将应用细化应用到您的 Xcode 归档并测试您的应用程序的精简变体，针对 iOS 13 设备。通过使用变薄变体进行测试，您将能够重现此崩溃。将应用细化应用到本地 Xcode 存档，使用 Ad-Hoc 从 Xcode 存档中导出应用程序或开发选项，然后选择“所有兼容的设备变体” 对于 App Thinning 选项。创建精简版本后，您可以通过阅读来识别针对 iOS 13 的特定变体作为输出一部分的 App Thinning Size Report 文件，然后安装并测试精简的 .ipa 文件。

请看：Apple Developer Forum

【讨论】：

可能值得一提的是，在我的应用程序中没有直接使用UISearchDisplayController，而只是一个默认的UISearchBar。但在故事板导航面板上往下看，有一个Search Display Controller（以及那个VC的First Responder和Exit），我删除了它并且没有破坏任何功能并停止了崩溃。胜利！
