ios requestAlwaysAuthorization 未显示权限警报

requestAlwaysAuthorization not showing permission alert

提问by Carlos Pastor

I'm trying to use some fancy iBeacons without success, kCLAuthorizationStatusNotDetermined all time. According to other questions it's a requirement to add those keys to info.plist (some questions says one, other says both). According to an article for iBeacons I need the Always option.

我一直在尝试使用一些花哨的 iBeacons，但没有成功，kCLAuthorizationStatusNotDetermined。根据其他问题，需要将这些键添加到 info.plist （有些问题说一个，其他说两个）。根据 iBeacons 的一篇文章，我需要 Always 选项。

<key>NSLocationWhenInUseUsageDescription</key>
<string>Nothing to say</string>
<key>NSLocationAlwaysUsageDescription</key>
<string>Permiso para acceder siempre</string>

At viewDidAppear:

在viewDidAppear：

self.locManager = [[CLLocationManager alloc]init];
self.locManager.delegate = self;
[self.locManager requestAlwaysAuthorization];
NSUUID* region1UUID = [[NSUUID alloc]initWithUUIDString:@""]; //ibeacon real UUID between "". Checked it's not nil.

self.beaconRegion = [[CLBeaconRegion alloc]
                                initWithProximityUUID:proximityUUID
                                identifier:@"myCoolString"];

self.beaconRegion.notifyEntryStateOnDisplay = YES;
self.beaconRegion.notifyOnEntry = YES;
self.beaconRegion.notifyOnExit = NO;
[self.locManager startMonitoringForRegion:self.beaconRegion];
[self.locManager startRangingBeaconsInRegion:self.beaconRegion];

Icon didn't appear at Settings/Privacy/Location until it was executed one of the two last methods. The Alert View to approve permissions never appears. If I perform a manual change at Location Settings and check it it will change status but at a few moments later Location at Settings will delete "Always" status for my app and will leave it blank again. Later I check with no luck

图标没有出现在设置/隐私/位置，直到它被执行最后两个方法之一。永远不会出现批准权限的警报视图。如果我在“位置设置”中执行手动更改并检查它会更改状态，但稍后“设置中的位置”将删除我的应用程序的“始终”状态，并将其再次留空。后来我检查没有运气

-(void)locationManager:(CLLocationManager *)manager didChangeAuthorizationStatus:(CLAuthorizationStatus)status {

Any ideas what is missing or wrong? Thank you

任何想法丢失或错误？谢谢

For iOS 11 developers, you should take a look at this post: Location Services not working in iOS 11.

对于 iOS 11 开发人员，您应该看看这篇文章：定位服务在 iOS 11 中不起作用。

TL;DR: you need ALL THREE location keys in the Info.plist:

TL;DR：您需要 Info.plist 中的所有三个位置键：

<key>NSLocationAlwaysAndWhenInUseUsageDescription</key>
<string>...</string>
<key>NSLocationAlwaysUsageDescription</key>
<string>...</string>
<key>NSLocationWhenInUseUsageDescription</key>
<string>...</string>

Along with InfoPlist.stringstranslations in case of multilingual apps.

随着InfoPlist.strings多语种应用程序的情况下翻译。

Had exactly the same problem. It turned out that in my case the NSLocationAlwaysUsageDescriptionwas required in my InfoPlist.stringslocalization files as well. Having NSLocationAlwaysUsageDescriptionin Info.plistwasn't enough...

有完全相同的问题。事实证明，在我的情况下NSLocationAlwaysUsageDescription，我的InfoPlist.strings本地化文件也需要。有NSLocationAlwaysUsageDescription在Info.plist是不够的......

I have noticed that if your instance of CLLocationManager is destroyed before the alert shows, you will never see the alert. In my case I was creating a local variable of the location manager in the AppDelegate to ask for permission.

我注意到，如果您的 CLLocationManager 实例在警报显示之前被销毁，您将永远不会看到警报。就我而言，我在 AppDelegate 中创建了位置管理器的局部变量以请求许可。

CLLocationManager *locationManager = [[CLLocationManager alloc] init];
if ([locationManager respondsToSelector:@selector(requestAlwaysAuthorization)]) {
    [locationManager requestAlwaysAuthorization];
}

Changing the local variable to an instance variable made the alert to display:

将局部变量更改为实例变量使警报显示：

@interface AppDelegate () {
    CLLocationManager *_locationManager;
}
@end

_locationManager = [[CLLocationManager alloc] init];
if ([_locationManager respondsToSelector:@selector(requestAlwaysAuthorization)]) {
    [_locationManager requestAlwaysAuthorization];
}

Just add this lines to your .plist file

只需将此行添加到您的 .plist 文件中

<key>NSLocationAlwaysUsageDescription</key>
<string>Optional message</string>

I got a similar problem recently with IOS 11 when I tried to use

我最近在尝试使用 IOS 11 时遇到了类似的问题

locationManager.requestAlwaysAuthorization()

The solution for me was to add all the 4 permissions in plist.info to get the alert:

我的解决方案是在 plist.info 中添加所有 4 个权限以获取警报：

• Privacy - Location When In Use Usage Description
• Privacy - Location Usage Description
• Privacy - Location Always Usage Description
• Privacy - Location Always and When In Use Usage Description

• 隐私 - 使用时的位置 使用说明
• 隐私 - 位置使用说明
• 隐私 - 位置始终使用说明
• 隐私 - 位置始终和使用时使用说明

Found, documented at forums and tested it's an Objective-C iOS 8 related bug. Same code written in Swift just works. Working swift code, delegate is call.

发现，在论坛上记录并测试它是一个与 Objective-C iOS 8 相关的错误。用 Swift 编写的相同代码也能正常工作。工作快速代码，委托是调用。

Add Core Location framework to Project Settings / Targets / Capabilities / Background Modes set "Location Updates" and "Uses Bluetooth LE Accessories" Add key at Info.plist NSLocationAlwaysUsageDescription

将核心位置框架添加到项目设置/目标/功能/后台模式设置“位置更新”和“使用蓝牙 LE 附件”在 Info.plist NSLocationAlwaysUsageDescription 添加密钥

import CoreLocation

class ViewController: UIViewController, CLLocationManagerDelegate  {

var locManager: CLLocationManager?

override func viewDidLoad() {
    super.viewDidLoad()
    self.locManager = CLLocationManager();
    self.locManager!.delegate = self;
    if (!CLLocationManager.locationServicesEnabled()) {
        println("Location services are not enabled");
    }
    self.locManager!.requestAlwaysAuthorization();
    self.locManager!.pausesLocationUpdatesAutomatically = false;
    let uuidString = ""  // My ibeacon string there
    let beaconIdentifier = "myCompany"
    let beaconUUID:NSUUID = NSUUID(UUIDString: uuidString)
    let beaconRegion:CLBeaconRegion = CLBeaconRegion(proximityUUID: beaconUUID,
        identifier: beaconIdentifier)
    self.locManager!.startMonitoringForRegion(beaconRegion)
    self.locManager!.startRangingBeaconsInRegion(beaconRegion)
    self.locManager!.startUpdatingLocation()
}

Dialog appears OK

对话框出现 OK

Make sure you add the keys to the correct Info.plist file. Don't forget there's one for your App and one for AppTest.

确保将密钥添加到正确的 Info.plist 文件中。不要忘记有一个用于您的应用程序，一个用于 AppTest。
