iOS swift : Send log information to iOS app from iOS framework

Question

我正在尝试了解如何将日志信息从我的 iOS 框架发送到我的 iOS 应用程序。在我的 iOS 应用程序中，我有 Crashlytics 设置，并且每当我从应用程序以及 iOS 框架获取一些日志时，我都希望使用 Crashlytics.sharedInstance().recordError(error)。

我阅读了多个答案，提到Crashlytics只能在应用程序中初始化一次，不建议在框架中再次初始化。 (例如 Link 1 )， Link 2 , Link 3 )

有人有针对这种要求的有效解决方案吗？

public final class MyAppSession {

    public fileprivate(set) var isValid: Bool = false

    let itemKey = MyAppSession.MyAppKeychainAccount
    let keychainAccessGroupName = MyAppConfigured?.keyChainGroup

    /**
     Attempts to restore a locally stored session.
     */
    public static func savedSession() -> MyAppSession? {

        do {

            let itemKey = MyAppSession.MyAppKeychainAccount
            let keychainAccessGroupName = MyAppConfigured?.keyChainGroup

            let queryLoad: [String: AnyObject] = [

一种选择是将错误日志记录委托(delegate)给您的应用程序。这使得它更加灵活。

例如:

protocol MyFrameworkErrorHandlingDelegate: AnyObject {
    func didReceiveError(_ error: Error)
}

然后在您的应用程序中，您可以创建此默认扩展

extension MyFrameworkErrorHandlingDelegate {
     func didReceiveError(_ error: Error) {
         Crashlytics.sharedInstance().recordError(error)
     }
}

这种方法的问题是决定在哪里使用它或在哪里分配委托(delegate)，这取决于您的框架的作用以及您的应用程序如何使用该框架。

编辑:

免责声明:这不是最有效的方法，但它是最直接的方法。

protocol MyFrameworkErrorHandlingDelegate: AnyObject {
    func didReceiveError(_ error: Error)
}

class MyAppLogger {

    static var delegate: MyFrameworkErrorHandlingDelegate?

    static func log(_ error: Error) {
        delegate?.didReceiveError(error)
    }
}

class AppDelegate: UIApplicationDelegate, MyFrameworkErrorHandlingDelegate

稍后在您的 AppDelegate 中

MyAppLogger.delegate = self
