iOS 8 requestWhenInUseAuthorization no Popup

问题描述

我试图让我的AppProject iOS 8准备就绪。我读了很多关于

  [_ locationManager requestWhenInUseAuthorization]; 
  

和plist中的条目

  NSLocationWhenInUseUsageDescription 
  

所以我改变了所有必要的代码行。 >

它工作正常，但现在我已经从我的iOS 7基础中再次复制我的项目以包含新功能。但是，当我对iOS8位置隐私进行更改时，弹出窗口不再出现。

我的代码一直工作，直到我复制。

 <？xml version =1.0encoding =UTF-8？> 
<！DOCTYPE plist PUBLIC -  // Apple // DTD PLIST 1.0 // ENhttp://www.apple.com/DTDs/PropertyList-1.0.dtd\"> 
< plist version =1.0>

< string> ????< / string> 
< key> CFBundleVersion< / key> 
< string> 1< / string> 
< / dict> 
< / plist> 
  

这里是我的电话

   - （instancetype）initWithCoder：（NSCoder *）coder 
 {
 self = [super initWithCoder：coder]; 
 if（self）{
 
 _UserLocation = [[CLLocation alloc] init]; 
 _locationManager = [[CLLocationManager alloc] init]; //初始化locationManager 
 _locationManager.delegate = self; 
 _locationManager.desiredAccuracy = kCLLocationAccuracyBest; //设置精度
 [_locationManager requestWhenInUseAuthorization]; // iOS 8必须为
 [_locationManager startUpdatingLocation]; //请求位置更新
 
 NSLog（@passed initwithcode）; 
 
} 
返回自我; 
} 
  

如何解决这个问题？

解决方案

lockquote
NSLocationWhenInUseUsageDescription（String - iOS）描述了
为什么应用程序在前台运行
时正常访问用户的位置。当您的应用使用位置
服务直接跟踪用户的当前位置时，请添加此密钥。此密钥
不支持使用位置服务监控区域或使用重要位置更改服务监控
用户的位置。
系统在请求使用位置服务许可的情况下在用户
中显示的警报面板中包含此键值。

这个键是当您使用CLLocationManager类的requestWhenInUseAuthorization
方法请求对
位置服务的授权时需要。 如果您在调用
requestWhenInUseAuthorization方法时没有包含此密钥，则该密钥不存在，
系统将忽略您的请求。

此密钥在iOS 8.0及更高版本中受支持。如果Info.plist文件
包含此密钥和NSLocationUsageDescription密钥，则
系统将使用此密钥并忽略NSLocationUsageDescription密钥。

阅读它。我发现将此密钥添加到您的info.plist最简单的方法是右键单击您的info.plist并选择
$ b

打开为 - >源代码

，然后在结尾 < / dict>< / plist>

 < key> NSLocationWhenInUseUsageDescription< / key> 
< string>< / string> 
  

如果您想要，您可以在< string>< ; / string> ，它描述了用户为什么要使用他/她的位置。此文本将显示在警报的默认文本下。

I tried to make my AppProject iOS 8 ready. I had read a lot about

[_locationManager requestWhenInUseAuthorization];

and the entry in plist

NSLocationWhenInUseUsageDescription

So I changed all the necessary code lines.

It works fine, but now I have copied my project again from my iOS 7 base to include new features. But when I make the changes for the iOS8 Location Privacy the Popup doesn't appear anymore.

My code worked until I copied.

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
    <dict>
        <key>NSLocationWhenInUseUsageDescription</key>
        <string>tolle sache </string>
        <key>CFBundleDevelopmentRegion</key>
        <string>en</string>
        <key>CFBundleExecutable</key>
        <string>${EXECUTABLE_NAME}</string>
        <key>CFBundleIdentifier</key>
        <string>fapporite.${PRODUCT_NAME:rfc1034identifier}</string>
        <key>CFBundleInfoDictionaryVersion</key>
        <string>6.0</string>
        <key>CFBundlePackageType</key>
        <string>BNDL</string>
        <key>CFBundleShortVersionString</key>
        <string>1.0</string>
        <key>CFBundleSignature</key>
        <string>????</string>
        <key>CFBundleVersion</key>
        <string>1</string>
    </dict>
</plist>

and here is my call

- (instancetype)initWithCoder:(NSCoder *)coder
{
    self = [super initWithCoder:coder];
    if (self) {

        _UserLocation = [[CLLocation alloc]init];
        _locationManager = [[CLLocationManager alloc]init]; // initializing locationManager
        _locationManager.delegate = self;
        _locationManager.desiredAccuracy = kCLLocationAccuracyBest; // setting the accuracy
        [_locationManager requestWhenInUseAuthorization]; // iOS 8 MUST
        [_locationManager startUpdatingLocation];  //requesting location updates

        NSLog(@"passed initwithcode");

    }
    return self;
}

How can I fix this?

解决方案

From the documentation

Read about it here.

I find that the easiest way to add this key to your info.plist is to right click you info.plist and choose

Open As->Source Code

and then add the following in the end before </dict></plist>

<key>NSLocationWhenInUseUsageDescription</key>
<string></string>

If you want you can add a text in between <string></string> that describes to the user why you want to use his/hers location. This text will show up under the default text in the alert.
