谷歌云消息仅在应用升级时崩溃

Question

我面临着一个针对iOS的Google云消息传递的奇怪问题。 调用

后，该应用程序崩溃了几秒钟

[[GGLContext sharedInstance] configureWithError:&configureError];

只有在已安装从应用商店下载的应用的较旧版本时，Xcode才会安装带有Google/CloudMessaging SDK的新应用。

但是，如果我在全新安装上运行它，一切都很顺利。

崩溃的原因是什么？以及如何解决？

// From Google GCM Sample app
// https://github.com/googlesamples/google-services/blob/master/ios/gcm/GcmExample/AppDelegate.m
- (void)configureGCM {
    NSLog(@"Start ConfigureGCM");
    NSError* configureError;
    [[GGLContext sharedInstance] configureWithError:&configureError];
    NSAssert(!configureError, @"Error configuring Google services: %@", configureError);
    _gcmSenderID = [[[GGLContext sharedInstance] configuration] gcmSenderID];
    NSLog(@"gcmSenderID : %@, ConfigureError: %@", _gcmSenderID, configureError);
    GCMConfig *gcmConfig = [GCMConfig defaultConfig];
    gcmConfig.receiverDelegate = self;
    [[GCMService sharedInstance] startWithConfig:gcmConfig];

    __weak typeof(self) weakSelf = self;

    _gcmRegistrationHandler = ^(NSString *registrationToken, NSError *error){
        if (registrationToken != nil) {
            NSLog(@"GCM Registration Token: %@", registrationToken);
            if(![weakSelf.user hasSyncedGCMToken]) {
                [weakSelf.user syncGCMTokenWithServer:registrationToken];
            }
        } else {
            NSLog(@"Registration to GCM failed with error: %@", error.localizedDescription);
        }
    };
    NSLog(@"End ConfigureGCM");
}

以下是日志：

更新

iOS8或更高版本似乎没有发生此问题。 对我来说，崩溃是在iPhone 5上使用iOS 7.0.4

更新-2

目前，我仅针对iOS 8+用户使用推送通知。仍在等待Google的回复on Github

更新-3

已在最新版本的GCM中修复
