Location Services not working in iOS 11
提问by William George
I just rebuilt my app with the iOS 11 SDK in an attempt to remove the blue bannerthat is now always appearing. I thought - "Brilliant, that worked", only to discover that location services are now not working at all.
我刚刚使用 iOS 11 SDK 重建了我的应用程序，试图删除blue banner现在总是出现的应用程序。我想 - “太棒了，那行得通”，结果发现定位服务现在根本不起作用。
The application used to work with iOS 10 - Has anybody heard anything?
该应用程序曾经适用于 iOS 10 - 有人听说过吗？

It would appear that apple have added yet another privacy feature. The user is now able to override our requestAlwaysAuthorizationand downgrade it to requestWhenInUseAuthorization- Which means as a developer we now have to supply both descriptions in the Info.plist
苹果似乎还添加了另一个隐私功能。用户现在可以覆盖我们的requestAlwaysAuthorization并将其降级为requestWhenInUseAuthorization- 这意味着作为开发人员，我们现在必须在Info.plist
I found that they have added a new key NSLocationAlwaysAndWhenInUseUsageDescription
我发现他们添加了一个新密钥 NSLocationAlwaysAndWhenInUseUsageDescription
/*
* Either the NSLocationAlwaysAndWhenInUseUsageDescription key or both the
* NSLocationAlwaysUsageDescription and NSLocationWhenInUseUsageDescription
* keys must be specified in your Info.plist; otherwise, this method will do
* nothing, as your app will be assumed not to support Always authorization.
*/
However, upon using this new key - the location service still didn't work, upon further searching I found this gem mixed in with all the extra debugging information:
但是，在使用这个新密钥时 - 位置服务仍然不起作用，进一步搜索后，我发现这个 gem 与所有额外的调试信息混合在一起：
This app has attempted to access privacy-sensitive data without a usage description. The app's Info.plist must contain both NSLocationAlwaysAndWhenInUseUsageDescription and NSLocationWhenInUseUsageDescription keys with string values explaining to the user how the app uses this data
此应用程序试图在没有使用说明的情况下访问隐私敏感数据。应用程序的 Info.plist 必须包含 NSLocationAlwaysAndWhenInUseUsageDescription 和 NSLocationWhenInUseUsageDescription 键，并带有字符串值向用户解释应用程序如何使用这些数据
Which directly contradicts the the comment that I found in the updated CLLocationManager.hfile. So I've created a radar.
这直接与我在更新CLLocationManager.h文件中找到的评论相矛盾。所以我创建了一个雷达。
Good news, if you follow the advice of the debugging console, IE. add both the new key NSLocationAlwaysAndWhenInUseUsageDescriptionand one of the old keys NSLocationWhenInUseUsageDescription, locations services will start to work again.
好消息，如果您遵循调试控制台 IE 的建议。添加新密钥NSLocationAlwaysAndWhenInUseUsageDescription和旧密钥之一NSLocationWhenInUseUsageDescription，位置服务将再次开始工作。

Just to add the steps on fixing this:
只是添加解决此问题的步骤：
2 ways to do it:
2种方法：
A) The easy way: Select your Info.plist file, add the properties, note that they start with PRIVCY instead of LOCATION... therefore, the exact names of these variables starts with "Privacy - Location ... " etc, add each here, and describe how the user would be seeing this on the warning.
A) 简单的方法：选择您的 Info.plist 文件，添加属性，注意它们以 PRIVCY 而不是 LOCATION 开头...因此，这些变量的确切名称以“Privacy - Location ...”等开头，添加每个在这里，并描述用户将如何在警告中看到这一点。
B) The hard / interesting / programatic way (I like this way more):
B）硬/有趣/程序化的方式（我更喜欢这种方式）：
Right click on your Info.plist for your app, and then select "View source code", you should see it all in XML,
右键单击您的应用程序的 Info.plist，然后选择“查看源代码”，您应该会在 XML 中看到所有内容，
Follow the other ...... format, and add these properties as follows:
按照其他......格式，并添加这些属性如下：
<key>NSLocationAlwaysUsageDescription</key>
<string>Program requires GPS to track cars and job orders</string>
<key>NSLocationAlwaysAndWhenInUseUsageDescription</key>
<string>Program requires GPS to track cars and job orders</string>
<key>NSLocationWhenInUseUsageDescription</key>
<string>Program requires GPS to track cars and job orders</string>
<key>NSMicrophoneUsageDescription</key>
<string>This app uses your Microphone to allow Voice over IP communication with the Program Admin system</string>
Save, and then right-click on the info.plist file, and then select Property list, this should view the file back into the default view.
保存，然后右键单击info.plist 文件，然后选择Property list，这样应该会将文件查看回默认视图。
EDIT:
编辑：
Another member asked for code, here it is:
另一位成员要求提供代码，这里是：
1) On your .H file, add:
1) 在您的 .H 文件中，添加：
@property (strong, nonatomic) CLLocationManager *LocationManager;
2) On your .M file add under ViewDidAppear() function:
2) 在您的 .M 文件中添加 ViewDidAppear() 函数：
_LocationManager = [[CLLocationManager alloc] init];
[_LocationManager setDelegate:self];
_LocationManager.desiredAccuracy = kCLLocationAccuracyBestForNavigation;
_LocationManager.pausesLocationUpdatesAutomatically = NO;
[_LocationManager requestAlwaysAuthorization];
_LocationManager.headingFilter = 5;
_LocationManager.distanceFilter = 0;
[_LocationManager startUpdatingLocation];
[_LocationManager startUpdatingHeading];
This what works fine for me, hopefully the code would work for you too.
这对我来说很好用，希望代码也适合你。

working under iOS11 i discovered, that Info.plist needs al least NSLocationAlwaysAndWhenInUseUsageDescription in Info.plist:
在 iOS11 下工作我发现，Info.plist 在 Info.plist 中至少需要 NSLocationAlwaysAndWhenInUseUsageDescription：
Strange enough when your app is multilingualthe localized versions of your strings need all three keysmentioned in this post else requestAlwaysAuthorization()and locationManager(_ manager: CLLocationManager, didChangeAuthorization status: CLAuthorizationStatus)will fail silently.
奇怪的是，当您的应用程序是多语言时，您的字符串的本地化版本需要本文中提到的所有三个键，requestAlwaysAuthorization()并且locationManager(_ manager: CLLocationManager, didChangeAuthorization status: CLAuthorizationStatus)会静默失败。

Hope this saves you time when stumbling upon.

Follow these steps:
按着这些次序：
I ran into the same issue with an app that needed "Always Authorization", and resolved it by following these steps:
我在需要“始终授权”的应用程序中遇到了同样的问题，并按照以下步骤解决了这个问题：
1.AddNSLocationWhenInUseUsageDescriptionkey to Info.plist
1.添加NSLocationWhenInUseUsageDescription密钥Info.plist
2.AddNSLocationAlwaysAndWhenInUseUsageDescriptionto Info.plist
2.添加NSLocationAlwaysAndWhenInUseUsageDescription到Info.plist
3.AddNSLocationAlwaysUsageDescriptionto Info.plist(to support < iOS 11)
3.添加NSLocationAlwaysUsageDescription到Info.plist（支持<iOS 11）
4.CallrequestWhenInUseAuthorization()BEFORErequestAlwaysAuthorization()
4.之前打电话)requestWhenInUseAuthorization()requestAlwaysAuthorization(
You cannot execute requestAlwaysAuthorization() before requestWhenInUseAuthorization(). You must escalate to that permission level. Once I made these changes, location updates started working properly again.
您不能在 requestWhenInUseAuthorization() 之前执行 requestAlwaysAuthorization()。您必须升级到该权限级别。进行这些更改后，位置更新再次开始正常工作。

Step 1. you must add following privacy permissions in plist file
步骤 1. 您必须在 plist 文件中添加以下隐私权限
<key>NSLocationAlwaysAndWhenInUseUsageDescription</key>
<string>Application requires user's location for better user experience.</string>
<key>NSLocationAlwaysUsageDescription</key>
<string>Application requires user's location for better user experience.</string>
<key>NSLocationWhenInUseUsageDescription</key>
<string>Application requires user's location for better user experience.</string>
Step 2. make sure you have following swift code to get current locations
第 2 步。确保您有以下 swift 代码以获取当前位置
import UIKit
import MapKit
import CoreLocation
class ViewController: UIViewController, CLLocationManagerDelegate {
// MARK: Variables declearations
@IBOutlet weak var mapView: MKMapView!
var locationManager: CLLocationManager!
// MARK: View Controller life cycle methods
override func viewDidLoad() {
super.viewDidLoad()
//TODO: Make user you must add following three privacy permissions in plist
//NSLocationWhenInUseUsageDescription
//NSLocationAlwaysAndWhenInUseUsageDescription
//NSLocationAlwaysUsageDescription
getCurrentLocation()
}
func getCurrentLocation()
{
if (CLLocationManager.locationServicesEnabled())
{
locationManager = CLLocationManager()
locationManager.delegate = self
locationManager.desiredAccuracy = kCLLocationAccuracyBest
locationManager.requestAlwaysAuthorization()
locationManager.startUpdatingLocation()
}
}
// MARK: Location Manager Delegate methods
func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation])
{
let locationsObj = locations.last! as CLLocation
print("Current location lat-long is = \(locationsObj.coordinate.latitude) \(locationsObj.coordinate.longitude)")
showOnMap(location: locationsObj)
}
func locationManager(_ manager: CLLocationManager, didFailWithError error: Error) {
print("Get Location failed")
}
func showOnMap(location: CLLocation )
{
let center = CLLocationCoordinate2D(latitude: location.coordinate.latitude, longitude: location.coordinate.longitude)
let region = MKCoordinateRegion(center: center, span: MKCoordinateSpan(latitudeDelta: 0.01, longitudeDelta: 0.01))
mapView.setRegion(region, animated: true)
}
}
