ios - UIButton 事件跟踪 Google Analytics(Swift)

Question

我想使用 Google Analytics 跟踪用户点击 UIButton 时的事件。我有下面的代码，但显示错误。我哪里错了？谢谢

代码:

@IBAction func startGame1(sender: AnyObject) {

        var tracker = GAI.sharedInstance().defaultTracker

        tracker.send(GAIDictionaryBuilder.createEventWithCategory("Game 1", action: "Start Pressed", label: "Start Timer One", value: nil).build()) 
    }

错误:

Cannot invoke 'send' with an argument list of type'(NSMutableDictionarry)'

Answer 1

自 Swift 1.2 发布以来，您必须将 GAIDictionaryBuilder 转换为 [NSObject : AnyObject]

在 StackOverflow 上查看这篇文章

Google Analytics not working with Swift 1.2 and Xcode 6.3

你的问题有解决方案

@IBAction func startGame1(sender: AnyObject) {

        var tracker = GAI.sharedInstance().defaultTracker

        tracker.send(GAIDictionaryBuilder.createEventWithCategory("Game 1", action: "Start Pressed", label: "Start Timer One", value: nil).build() as [NSObject : AnyObject]) 
    }

希望对您有所帮助!
