位置服务在iOS 8中不起作用-Java 学习之路

603

我在iOS 7上运行良好的应用程序无法与iOS 8 SDK一起使用 .

CLLocationManager 不't return a location, and I don't在设置 - >位置服务下看到我的应用程序 . 我在这个问题上进行了谷歌搜索，但没有出现任何问题 . 可能有什么不对？

对于那些使用 Xamarin 的人，我必须手动将密钥 NSLocationWhenInUseUsageDescription 添加到info.plist，因为它在Xamarin 5.5.3 Build 6或XCode 6.1的下拉列表中不可用 - 只有 NSLocationUsageDescription 在列表中，这导致 CLLocationManager 继续默默地失败 .

我最终解决了自己的问题 .

显然在iOS 8 SDK中， requestAlwaysAuthorization （用于后台位置）或 requestWhenInUseAuthorization （仅在前景时的位置）在开始位置更新之前需要调用 CLLocationManager .

Info.plist 中还需要 NSLocationAlwaysUsageDescription 或 NSLocationWhenInUseUsageDescription 键，并在提示中显示消息 . 添加这些解决了我的问题 .

希望它可以帮助别人 .

我也在用同样的问题拔出头发 . Xcode为您提供错误：

尝试在不提示位置授权的情况下启动MapKit位置更新 . 必须首先调用 - [CLLocationManager requestWhenInUseAuthorization]或 - [CLLocationManager requestAlwaysAuthorization] .

但即使您实现上述方法之一，它也不会提示用户，除非info.plist中有 NSLocationAlwaysUsageDescription 或 NSLocationWhenInUseUsageDescription 的条目 .

将以下行添加到info.plist，其中字符串值表示您需要访问用户位置的原因
```
<key>NSLocationWhenInUseUsageDescription</key>
<string>This application requires location services to work</string>

<key>NSLocationAlwaysUsageDescription</key>
<string>This application requires location services to work</string>
```
我认为自从我在Xcode 5中启动这个项目后，这些条目可能已经丢失 . 我猜Xcode 6可能会为这些键添加默认条目但尚未确认 .

您可以在这两个设置上找到更多信息here

为了确保这与iOS 7向后兼容，您应该检查用户是运行iOS 8还是iOS 7.例如：

#define IS_OS_8_OR_LATER ([[[UIDevice currentDevice] systemVersion] floatValue] >= 8.0)

//In ViewDidLoad
if(IS_OS_8_OR_LATER) {
   [self.locationManager requestAlwaysAuthorization];
}

[self.locationManager startUpdatingLocation];

    [locationManager startUpdatingLocation];

根据Apple文档：
- https://developer.apple.com/documentation/corelocation/requesting_permission_to_use_location_services
- https://developer.apple.com/documentation/corelocation/cllocationmanager/1620562-requestwheninuseauthorization
从iOS 8开始，在注册位置更新之前，还需要在您的app 's Info.plist file is required. It'中存在 NSLocationWhenInUseUsageDescription 或 NSLocationAlwaysUsageDescription 键值，以便根据需要调用 [self.myLocationManager requestWhenInUseAuthorization] 或 [self.myLocationManager requestAlwaysAuthorization] 来请求用户的许可 . 然后，您在Info.plist中输入的字符串将显示在随后的对话框中 .

如果用户授予权限，则照常营业 . 如果他们拒绝许可，则不会通知代表位置更新 .

        if (currentLocation != nil) {

            latitudeLabel.text = [NSString stringWithFormat:@"%.8f", currentLocation.coordinate.latitude];
        }
    }

在iOS 8中，您需要做两件额外的事情才能使位置正常工作：在Info.plist中添加一个密钥，并向位置管理员请求授权以启动它 . 新位置授权有两个Info.plist键 . 需要这些键中的一个或两个 . 如果两个键都不存在，则可以调用startUpdatingLocation，但位置管理器实际上不会启动 . 它也不会向委托发送失败消息（因为它从未启动过，它不会失败） . 如果您添加一个或两个密钥但忘记明确请求授权，它也将失败 . 因此，您需要做的第一件事是将以下一个或两个密钥添加到Info.plist文件中：

NSLocationWhenInUseUsageDescription
NSLocationAlwaysUsageDescription

这两个键都带有一个字符串

这是您需要位置服务的原因的说明 . 您可以输入一个字符串，如“需要位置以查找您所在的位置”，如iOS 7中所示，可以在InfoPlist.strings文件中进行本地化 .

    [locationmanager requestAlwaysAuthorization];

要在iOS 8中访问用户位置，您必须添加，
```
NSLocationAlwaysUsageDescription in the Info.plist
```
这将要求用户获得获取其当前位置的许可 .

询问位置的旧代码在iOS 8中不起作用 . 您可以尝试使用此方法进行位置授权：

- (void)requestAlwaysAuthorization
{
    CLAuthorizationStatus status = [CLLocationManager authorizationStatus];

    // If the status is denied or only granted for when in use, display an alert
    if (status == kCLAuthorizationStatusAuthorizedWhenInUse || status ==        kCLAuthorizationStatusDenied) {
        NSString *title;
        title = (status == kCLAuthorizationStatusDenied) ? @"Location services are off" :   @"Background location is not enabled";
        NSString *message = @"To use background location you must turn on 'Always' in the Location Services Settings";

在iOS 8中，您需要做两件额外的事情才能使位置正常工作：在Info.plist中添加一个密钥，并向位置管理员请求授权，要求它启动

info.plist:

<key>NSLocationUsageDescription</key>
<string>I need location</string>
<key>NSLocationAlwaysUsageDescription</key>
<string>I need location</string>
<key>NSLocationWhenInUseUsageDescription</key>
<string>I need location</string>

    [locationmanager requestWhenInUseAuthorization];

    [locationmanager requestAlwaysAuthorization];

One common error for Swift developers:

首先确保为 NSLocationWhenInUseUsageDescription 或 NSLocationAlwaysUsageDescription 的plist添加值 .

如果您仍然没有看到弹出窗口要求授权，请查看是否将 var locationManager = CLLocationManager() 行放在View Controller的 viewDidLoad 方法中 . 如果你这样做，那么即使你打电话 locationManager.requestWhenInUseAuthorization() ，也不会显示任何内容 . 这是因为在viewDidLoad执行之后，将取消分配（清除）locationManager变量 .

解决方案是将行 var locationManager = CLLocationManager() 定位在类方法的顶部 .

在 [locationManager startUpdatingLocation]; 之前，添加iOS8位置服务请求：
```
if([locationManager respondsToSelector:@selector(requestAlwaysAuthorization)])
    [locationManager requestAlwaysAuthorization];
```
编辑您的应用 Info.plist 并添加密钥 NSLocationAlwaysUsageDescription ，将显示给用户的字符串值（例如， We do our best to preserve your battery life. ）

如果您的应用仅在应用开放时需要位置服务，请替换：

requestAlwaysAuthorization 与 requestWhenInUseAuthorization 和

NSLocationAlwaysUsageDescription 与 NSLocationWhenInUseUsageDescription .

我正在开发一个升级到iOS 8且位置服务停止运行的应用程序 . 您可能会在调试区域中得到错误，如下所示：

Trying to start MapKit location updates without prompting for location authorization. Must call -[CLLocationManager requestWhenInUseAuthorization] or -[CLLocationManager requestAlwaysAuthorization] first.

我做了最少侵入性的程序 . 首先将 NSLocationAlwaysUsageDescription 条目添加到info.plist：

注意我没有填写此密钥的值 . 这仍然有效，我并不担心，因为这是一个内部应用程序 . 此外，已经有一个 Headers 要求使用位置服务，所以我不想做任何多余的事情 .

接下来我为iOS 8创建了一个条件：
```
if ([self.locationManager respondsToSelector:@selector(requestAlwaysAuthorization)]) {
    [_locationManager requestAlwaysAuthorization];
}
```
在此之后调用 locationManager:didChangeAuthorizationStatus: 方法：
```
- (void)locationManager:(CLLocationManager *)manager didChangeAuthorizationStatus:  (CLAuthorizationStatus)status
{
    [self gotoCurrenLocation];
}
```
现在一切正常 . 一如既往，请查看documentation .

向后兼容的解决方案：

if ([CLLocationManager authorizationStatus] == kCLAuthorizationStatusNotDetermined &&
    [self.locationManager respondsToSelector:requestSelector]) {
    [self.locationManager performSelector:requestSelector withObject:NULL];
} else {

我在iOS9中遇到了类似的错误（使用Xcode 7和Swift 2）： Trying to start MapKit location updates without prompting for location authorization. Must call -[CLLocationManager requestWhenInUseAuthorization] or -[CLLocationManager requestAlwaysAuthorization] first. 我正在关注一个教程，但导师使用的是iOS8和Swift 1.2 . 在Xcode 7和Swift 2中有一些变化，我找到了这个代码，它对我来说很好（如果有人需要帮助）：

    func locationManager(manager: CLLocationManager, didFailWithError error: NSError) {

为了访问iOS中的用户位置 . 您需要添加两个键

NSLocationWhenInUseUsageDescription

NSLocationAlwaysUsageDescription

进入Info.plist文件 .

<key>NSLocationWhenInUseUsageDescription</key>
    <string>Because I want to know where you are!</string>

- 添加键 NSLocationWhenInUseUsageDescription 或 NSLocationAlwaysUsageDescription （背景GPS使用），字符串要求在每个目标的每个 info.plist 上使用GPS .
- 通过运行请求权限：
[self initLocationManager：locationManager];

initLocationManager 的位置是：
```
// asks for GPS authorization on iOS 8
-(void) initLocationManager:(CLLocationManager *) locationManager{

    locationManager = [[CLLocationManager alloc]init];

    if([locationManager respondsToSelector:@selector(requestAlwaysAuthorization)])
        [locationManager requestAlwaysAuthorization];
}
```
请记住，如果每个目标上的键都没有 info.plist ，则应用程序不会询问用户 . if 提供与iOS 7的兼容性， respondsToSelector: 方法保证了未来的兼容性，而不仅仅是解决iOS 7和8的问题 .

我在 iOS 8.4, iPad mini 2. 中添加了这些键 iOS 8.4, iPad mini 2. 它也有效 . 我没有在 Info.plist 中设置任何键，如 NSLocationWhenInUseUsageDescription .

InfoPlist.strings：
```
"NSLocationWhenInUseUsageDescription" = "I need GPS information....";
```
Base on this thread，它说， as in iOS 7 ，可以在InfoPlist.strings中本地化 . 在我的测试中，这些键可以直接在文件 InfoPlist.strings 中配置 .

因此，您需要做的第一件事是将以下一个或两个键添加到Info.plist文件中：NSLocationWhenInUseUsageDescription NSLocationAlwaysUsageDescription这两个键都带有一个字符串，该字符串描述了您需要位置服务的原因 . 您可以输入一个字符串，如“需要位置以查找您所在的位置”，如iOS 7中所示，可以在InfoPlist.strings文件中进行本地化 .

UPDATE:

我认为@IOS's method is better.使用空值为 Info.plist 添加键并将本地化字符串添加到 InfoPlist.strings .
