应用程序在使用 NewRelic 框架的设备上启动时崩溃

Question

我有基于 swift 的应用程序 NewRelicAgent.framework 集成...

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
    // Register the analytics app
    NewRelicAgent.startWithApplicationToken("AA****************************6");

应用程序在 LoginViewController 上崩溃，启动时第一个视图控制器，日志如下 -

LoginViewController 是普通 ZViewController 的子类...

class ZViewController: UIViewController {

    override func viewDidLoad() {
        super.viewDidLoad()

    }
}

class LoginViewController: ZViewController {
...
...
}

我的任何视图控制器或项目中都没有与 NewRelicAgent 相关的任何其他代码（项目目标中的 RunScript 除外）。

有解决办法吗？

编辑：使用 FIX :)

    func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
        // Register the analytics app
        NewRelicAgent.enableFeatures(NRMAFeatureFlags.NRFeatureFlag_SwiftInteractionTracing);
        NewRelicAgent.startWithApplicationToken("AA****************************6");

        // Your app specific code.......

    }

// Add 'dynamic' before viewDidLoad method and probably any other view life cycle method or method to be traced for analytics
class ZViewController: UIViewController {

    override dynamic func viewDidLoad() {
         super.viewDidLoad()
         // Your implementation...
    }
}

Answer 1

解决方法之一是避免 UIViewController 的多级继承 -

class LoginViewController: UIViewController {
...
...
}

似乎当前 NewRelic 框架在继承/swift 采用方面存在一些问题。

Answer 2

Swift 应用程序需要在 New Relic 中进行一些额外的配置：

https://docs.newrelic.com/docs/mobile-monitoring/new-relic-mobile/getting-started/enabling-swift-interaction-traces

您是否已将 dynamic 声明修饰符添加到您的方法中并使用功能标志启用 Swift 交互跟踪？
