[Firebase/Core] [I-COR000020]错误发布到Clearcut:错误域= NSURLErrorDomain代码= -1009"Internet连接似乎处于脱机状态

Question

我正在使用FireBase SDK作为我的应用程序的后端,并且我已根据需要启用了持久性.

[FIRDatabase database].persistenceEnabled = YES;

脱机模式运行良好,直到最近我在离线模式下使用我的应用程序时才开始出现此错误.

2017-01-08 19:03:44.838 MyApp[1002] <Error> [Firebase/Core][I-COR000020] Error posting to Clearcut: Error Domain=NSURLErrorDomain Code=-1009 "The Internet connection appears to be offline." UserInfo={NSUnderlyingError=0x170056710 {Error Domain=kCFErrorDomainCFNetwork Code=-1009 "(null)" UserInfo={_kCFStreamErrorCodeKey=50, _kCFStreamErrorDomainKey=1}}, NSErrorFailingURLStringKey=https://play.googleapis.com/log, NSErrorFailingURLKey=https://play.googleapis.com/log, _kCFStreamErrorDomainKey=1, _kCFStreamErrorCodeKey=50, NSLocalizedDescription=The Internet connection appears to be offline.}, with Status Code: 0

这很容易重现.只需在iPhone上的飞行模式之间切换即可看到此错误.

我正在使用CocoaPods来使用FireBase,这里是框架列表及其版本.

-> Using Firebase (3.11.0)

-> Using FirebaseAnalytics (3.6.0)

-> Using FirebaseAuth (3.1.0)

-> Using FirebaseCore (3.4.6)

-> Using FirebaseDatabase (3.1.1)

-> Using FirebaseInstanceID (1.0.8)

我无法修复 firebase 代码，但我能够将其包装在异常处理中，以阻止它在设备上的互联网连接关闭时（特别是在 iPad2 上）使我的应用程序崩溃。

            @try {
            [FIRAnalytics logEventWithName:@"share" parameters:@{
        @"item_id" : [[[StatusReportIAPHelper sharedInstance] product] productIdentifier],
                 @"content_type" : @{@"title": [[[StatusReportIAPHelper sharedInstance] product] localizedTitle]}
              }];
             }
             @catch (NSException* exception) {
                 NSLog(@"SRS.logEventWithName Exception: %@ Reason: %@", exception.name, exception.reason);
             }

        do {
                Analytics.logEvent(AnalyticsEventSelectContent, parameters: [
                    AnalyticsParameterItemID: "id-\(bundleID!)" as NSObject

                catch {
                    NSLog("POAD.logEvent Cannot log event - no Internet connection");
                }
