iOS 乱舞 : UI API called from background thread

Question

使用 xcode 9.3 beta 实现 flurry 会导致有关后台线程调用的 UI API 的警告。必须仅从主线程调用。

知道如何避免这种情况 - 是否只能通过 flurry 来解决？

应用程序委托(delegate)中使用的代码:

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {

    let builder = FlurrySessionBuilder.init()
                                      .withAppVersion("1.0")
                                      .withLogLevel(FlurryLogLevelAll)
                                      .withCrashReporting(true)
                                      .withSessionContinueSeconds(10)

    // Replace YOUR_API_KEY with the api key in the downloaded package
    Flurry.startSession("YOUR_API_KEY", with: builder)
    return true
}

试试这个:

objective-c

dispatch_async(dispatch_get_main_queue(), ^{
 // add UI related changes here
    });

swift

DispatchQueue.main.async {
// add UI related changes here
}
