Mixpanel 不适用于 swift

Posted 2023-03-08

【中文标题】Mixpanel 不适用于 swift

【英文标题】：Mixpanel does not work with swift

【发布时间】：2015-01-18 23:59:31

【问题描述】：

Cocoapods 还没有为 Swift 做好准备。当我在使用 Swift 的 ios 项目中实现 Mixpanel 时，出现了几个错误。

如何解决这个问题并让 mixpanel 正常工作？

【参考方案1】：

将这行代码添加到每个给出错误的文件中

#import <UIKit/UIKit.h>

还需要在链接的框架和库中添加这些：

libicucore.dylib  
CFNetwork.framework  
Security.framework

然后将其添加到您的 Bridging-Header.h 文件中：

#import "Mixpanel.h"

然后在你的 appdelegate 中添加这段代码：

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool 
    //other stuff here
    Mixpanel.sharedInstanceWithToken("yourtokennumbergoeshere")
    var mixPanel = Mixpanel.sharedInstance()

    mixPanel.track("Finished Launching", properties: ["name1":"property1","name2":"property2"])

    return true

【参考方案2】：

将您的 #import "mixpanel.h" 更改为 #import "Mixpanel/Mixpanel.h"

【讨论】：

很高兴我能帮上忙。

对于一个 swift 项目，导入应该是这样的：#import （详见developer.apple.com/library/ios/documentation/Swift/Conceptual/…）

【参考方案3】：

使用这个非官方的 Swift 客户端！可能不如真实的东西好，但它可以用于基本跟踪。 https://github.com/soffes/Mixpanel

【参考方案4】：

让 A/B 测试在 Swift 中工作并非易事，因为不支持宏。随意使用这个要点：

【讨论】：

我不敢相信这个要点仍然相关。他们还没有解决这些问题吗？

【参考方案5】：

看起来 Mixpanel 已经发布了一些官方文档： https://mixpanel.com/blog/2015/08/17/community-tip-implement-mixpanel-in-swift-apps

我在 podfile 和桥接头导入方面遇到了问题，但是 use_frameworks！上面链接中的建议非常适合我。
