ios - 无法将类型“NSMutableDictionary”的值转换为强制类型“[NSObject: AnyObject]”以用于 google ios Analytics

Question

我想将 google Analytics ios 添加到我的项目中，但是当我尝试将他们的代码粘贴到我的应用程序中时遇到了一些问题，如下面的代码。

var tracker = GAI.sharedInstance().defaultTracker
tracker.set(kGAIScreenName, value: "rootPlayView")

var builder = GAIDictionaryBuilder.createScreenView()
tracker.send(builder.build() as [NSObject : AnyObject])

然后我收到这样的错误

我怎样才能解决这个问题？

谢谢！

类型转换

屏幕轨道

let tracker = GAI.sharedInstance().defaultTracker
tracker.set(kGAIScreenName, value: "Home")
tracker.send(GAIDictionaryBuilder.createScreenView().build() as [AnyHashable : Any])

Objective-C

id<GAITracker> tracker = [[GAI sharedInstance] defaultTracker];
// Set the screen name on the tracker so that it is used in all hits sent from this screen.
[tracker set:kGAIScreenName value:@"Home"];
[tracker send:[[GAIDictionaryBuilder createScreenView]  build]]; 

自动屏幕跟踪

斯威夫特 3

override func viewDidAppear(_ animated: Bool) {
    super.viewDidAppear(animated)
    self!.screenName = "About Screen"
}

Objective-C

- (void)viewDidAppear:(BOOL)animated {
    [super viewDidAppear:animated];
    self.screenName = @"About Screen";
}

事件追踪

斯威夫特 3

let tracker = GAI.sharedInstance().defaultTracker

tracker!.send(GAIDictionaryBuilder.createEventWithCategory("ui_action", action: "button_press", label: "menuButton", play: nil).build())

Objective-C

id<GAITracker> tracker = [[GAI sharedInstance] defaultTracker];

[tracker send:[[GAIDictionaryBuilder createEventWithCategory:@"ui_action"     // Event category (required)
    action:@"button_press"  // Event action (required)
    label:@"play"           
    value:nil] build]];

或使用

weak var tracker = GAI.sharedInstance().defaultTracker
// Set screen name on the tracker to be sent with all hits.
 tracker!.set(kGAIScreenName, value: "Home Screen")
// Send a screen view for "Home Screen".
// [tracker send:[[GAIDictionaryBuilder createAppView] build]];   

// Previous V3 SDK versions.
tracker!.send(GAIDictionaryBuilder.createScreenView().build())

// SDK Version 3.08 and up.
// This event will also be sent with &cd=Home%20Screen.
tracker!.send(GAIDictionaryBuilder.createEventWithCategory("UX", action: "touch", label: "menuButton", value: nil).build())
// Clear the screen name field when we're done.
tracker!.set(kGAIScreenName, value: nil)

例子

尝试这个

var builder = GAIDictionaryBuilder.createScreenView().build() as! [NSObject : AnyObject]
tracker.send(builder)

用于屏幕轨道

let tracker = GAI.sharedInstance().defaultTracker
tracker.set(kGAIDescription, value: "rootPlayView")
let builder: NSObject = GAIDictionaryBuilder.createScreenView().build()
tracker.send(builder as! [NSObject : AnyObject])

用于事件跟踪

let tracker = GAI.sharedInstance().defaultTracker
let builder: NSObject = GAIDictionaryBuilder.createEventWithCategory(
            "xxxx",
            action: "buttonclicked",
            label: "you pressed xxx button",
            value: nil).build()
tracker.send(builder as! [NSObject : AnyObject])

Answer 2

此答案已针对 Swift 3 更新

let tracker = GAI.sharedInstance().defaultTracker
let eventTracker: NSObject = GAIDictionaryBuilder.createEvent( 
                withCategory: "SomeCategory",
                action: "SomeAction",
                label: "SomeLabel",
                value: nil).build()
tracker.send(eventTracker as [NSObject : AnyObject]!)

或者...

let tracker = GAI.sharedInstance().defaultTracker
tracker.set(kGAIDescription, value: "ScreenViewName")
let eventTracker: NSObject = GAIDictionaryBuilder.createScreenView().build()
tracker.send(eventTracker as! [NSObject : AnyObject])

Answer 3

对于 GA 3.17.0 使用：

let tracker = GAI.sharedInstance().defaultTracker
let builder = GAIDictionaryBuilder.createEvent(withCategory: category,
                                                     action: action,
                                                      label: nil,
                                                      value: nil).build()
tracker?.send(builder as [NSObject : AnyObject]!)

注意!末尾的[NSObject: AnyObject]!.

对惊人答案的小跟进，在 swift 3 中，方法是

let builder:NSObject = GAIDictionaryBuilder.createEvent(withCategory: category, action: eventName, label: label, value: nil).build()
