Type 'AppDelegate' does not conform to protocol 'CLLocationManagerDelegate' - Swift in Xcode 6
提问by J86
I am trying to use the significant-change location service. I am using Swift with XCode on OS Mavericks. I am attempting to enhance an iOS app that I built following a tutorial.
我正在尝试使用重大更改位置服务。我在 OS Mavericks 上使用 Swift 和 XCode。我正在尝试增强我按照教程构建的 iOS 应用程序。
In my AppDelegate.swiftfile I have created the following method to initialise my location manager service:
在我的AppDelegate.swift文件中，我创建了以下方法来初始化我的位置管理器服务：
func initializeLocationManager() {
// instance of location manager class
var locationManager = CLLocationManager()
locationManager.delegate = self // error here
locationManager.desiredAccuracy = kCLLocationAccuracyKilometer
locationManager.requestAlwaysAuthorization()
locationManager.startUpdatingLocation()
}
But on the 4th line of code, I get an error saying:
但是在第 4 行代码中，我收到一条错误消息：
Type 'AppDelegate' does not conform to protocol 'CLLocationManagerDelegate'
类型“AppDelegate”不符合协议“CLLocationManagerDelegate”
Why am I getting this error? How do I fix this?
为什么我收到这个错误？我该如何解决？

The error says:
错误说：
Type 'AppDelegate' does not conform to protocol 'CLLocationManagerDelegate'
类型“AppDelegate”不符合协议“CLLocationManagerDelegate”
So:
所以：
You are getting it because your class with the name AppDelegatedoes not conform to the protocol CLLocationManagerDelegate.
你得到它是因为你的名字的类AppDelegate不符合协议CLLocationManagerDelegate。
You can fix this by making that class conform to that protocol. So implement the methods that are required by the protocol, then declare that your class conforms to it.
您可以通过使该类符合该协议来解决此问题。因此，实现协议所需的方法，然后声明您的类符合它。

You have to provide at least the CLLocationManager.didUpdateLocationsfunction in your AppDelegate class.
您必须至少CLLocationManager.didUpdateLocations在 AppDelegate 类中提供该函数。
