我按照本指南Google Analytics for iOS尝试在我的iOS应用中设置Google Analytics 我已经完成了所有步骤,但是当我运行我的应用程序时,它会崩溃,并说我的defaultTracker是零。这是我的ViewController中的以下代码:
override func viewWillAppear(animated: Bool) {
super.viewWillAppear(animated)
var tracker = GAI.sharedInstance().defaultTracker
tracker.set(kGAIScreenName, value: nil)
var builder = GAIDictionaryBuilder.createScreenView()
tracker.send(builder.build() as [NSObject : AnyObject])
}
在我的AppDelegate中,我有这个代码,应该初始化有关跟踪器的所有内容:
func applicationDidFinishLaunching(application: UIApplication) {
// Configure tracker from GoogleService-Info.plist.
var configureError:NSError?
GGLContext.sharedInstance().configureWithError(&configureError)
assert(configureError == nil, "Error configuring Google services: \(configureError)")
// Optional: configure GAI options.
var gai = GAI.sharedInstance()
gai.trackUncaughtExceptions = true // report uncaught exceptions
gai.logger.logLevel = GAILogLevel.Verbose // remove before app release
}
有谁知道问题可能是什么以及如何解决?

我遇到了同样的问题,修正了在AppDelegate
applicationDidFinishLaunching
方法下添加默认跟踪器初始化,如下所示;
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
//...
var gai = GAI.sharedInstance()
gai.trackUncaughtExceptions = true // report uncaught exceptions
gai.defaultTracker = gai.trackerWithTrackingId("UA-XXXXX-X")
//...
}

我认为您需要在定义defaultTracker
变量后在gai
中设置applicationDidFinishLaunching
到gai
变量。
