CLLocationManager.location为nil [英] CLLocationManager.location is nil

问题描述

这是我的locationManager init方法：

this is my locationManager init method:

func initLocationManager() {
        seenError = false
        locationFixAchieved = false
        locationManager = CLLocationManager()
        locationManager.delegate = self
        locationManager.desiredAccuracy = kCLLocationAccuracyBest
        locationManager.requestAlwaysAuthorization()
        locationManager.startUpdatingLocation()     
}

调用此方法后此行

println(self.locationManager.location)

打印没有
为什么会这样？它在过去很适合我，我只是在我的应用程序中做了一些更改，现在效果不好..

prints nil why is that? it worked for me well at the past i just made few changes in my app and it doesn't work well now..

推荐答案

1） CLLocation位置文档
- 如果没有检索到任何位置数据，则此属性的值为nil。

1) CLLocation location documentation - The value of this property is nil if no location data has ever been retrieved.

2）你已经设置CLLocationManager的委托。为什么不实施 locationManager：didUpdateLocations：并从内部打印最新检索的位置？

2) You've set the delegate for CLLocationManager. Why not implement locationManager:didUpdateLocations: and print the latest retrieved location from inside?

3）您使用的是模拟器还是真实设备？请记住，如果您使用的是模拟器，则可能需要启用模拟位置：

3) Are you using a simulator or a real device? Bear in mind that if you are using a simulator you may need to enable simulate location:

您还可以在以下位置找到自定义位置选项：
- 模拟器 - >调试 - >位置 - >自定义位置...

You can also find a Custom Location option in: - Simulator -> Debug -> Location -> Custom Location...
