    近日遇到通过xcode的upload to AppStrore 上传成功后,在iTunes的MyApps中找不到构建的版本~,后面通过查询资料才知道。是因为申请对应权限时没有在value中填写对应内容引起的~~markmarkmark。蠢哭了

    原文

    由于苹果对于获取用户隐私权限的严格控制,在获取用户相机/相册/位置/通知等权限时,必须由用户手动授权之后方可获取。故事,就是在这样的场景下开始的...

    一、权限设置

    Q:获取对应权限需要做些什么?

    A:需要在info.plist中预设对应权限key值,如下

    Privacy - Camera Usage Description -> 相机
    
    Privacy - Microphone Usage Description -> 麦克风
    
    Privacy - Photo Library Usage Description -> 读取相册
    Privacy - Photo Library Additions Usage Description -> 保存图片至相册
    
    Privacy - NSLocationAlwaysUsageDescription -> 始终获取地理位置
    Privacy - NSLocationWhenInUseUsageDescription -> 使用时获取地理位置
    
    PS:位置授权二选一即可
    

    在使用对应功能如调起相册时系统会弹框要求用户授权。

    二、授权状态检测

    Q:如果用户没有同意授权或拒绝授权,如何保证在使用相关功能时提示用户开启权限?

    A:需要检测对应权限状态,

    如果用户未授权---->提示用户授权(系统行为)

    如果用户之前拒绝授权---->提示用户开启授权(App实现)

    如下

    检测麦克风权限<支持7.0+>

    +(BOOL)detectionMediaState:(void(^)())authorizedBlock
    {
       BOOL isAvalible = NO;
    
       NSString *mediaType = AVMediaTypeAudio; 
       AVAuthorizationStatus authStatus = [AVCaptureDevice authorizationStatusForMediaType:mediaType];
    
       //用户尚未授权->申请权限
       if (authStatus == AVAuthorizationStatusNotDetermined)
       {
           [AVCaptureDevice requestAccessForMediaType:mediaType completionHandler:^(BOOL granted) {
           
           if(granted)
            {
                if (authorizedBlock)
                {
                    authorizedBlock();
                }
            }}];
       }
       //用户已经授权
       else if (authStatus == AVAuthorizationStatusAuthorized)
       {
            isAvalible = YES;
        
            if (authorizedBlock)
            {
                authorizedBlock();
            }
       }
       //用户拒绝授权
       else
       {
           //提示用户开启麦克风权限
           [SystemManager openSettingPagewithMessage:@"麦克风"];
       }
       
       return isAvalible;
       
    }
    

    相册访问权限<支持7.0+>

         {
             PHAuthorizationStatus authStatus = [PHPhotoLibrary authorizationStatus];
        
             //用户尚未授权
             if (authStatus == PHAuthorizationStatusNotDetermined)
             {
                 [PHPhotoLibrary requestAuthorization:^(PHAuthorizationStatus status) {
                
                 if (status == PHAuthorizationStatusAuthorized)
                 {
                    if (authorizedBlock)
                    {
                        authorizedBlock();
                    }
                 }}];
              }
              //用户已经授权
              else if (authStatus == PHAuthorizationStatusAuthorized)
              {
                  isAvalible = YES;
            
                  if (authorizedBlock)
                  {
                     authorizedBlock();
                  }
              }
              //用户拒绝授权
              else
              {
                  //提示用户开启相册权限
                  [SystemManager openSettingPagewithMessage:@"照片"];
              }
          }
          else

    相机访问权限<支持7.0+>

            [AVCaptureDevice requestAccessForMediaType:AVMediaTypeVideo completionHandler:^(BOOL granted) {
            
                if (granted)
                {

                    }
                }
            }];
        }
        //用户已经授权
        else if (authStatus == AVAuthorizationStatusAuthorized)
        {
            isAvalible = YES;
        
            if (authorizedBlock)

        }
    
        return isAvalible;

    通知权限<支持8.0+>

    +(BOOL)detectionNotificationState:(void(^)())authorizedBlock
    {
        BOOL isAvalible = NO;
    
        if (iOS8OrLater)
        {
            //用户拒绝授权
            if ([UIApplication sharedApplication].currentUserNotificationSettings.types == UIUserNotificationTypeNone)
            {
                isAvalible = NO;

    定位权限<支持8.0+>
     +(BOOL)detectionLocationState:(void(^)())authorizedBlock
    {
    
        BOOL isAvalible = NO;
    
        CLAuthorizationStatus  authStatus = [CLLocationManager authorizationStatus];
    
        if (iOS8OrLater)
        {
            //用户尚未授权
            if (authStatus == kCLAuthorizationStatusNotDetermined)
            {                
                   //检测位置服务是否可用   
                   if([CLLocationManager locationServicesEnabled])      
                   {
        
                        if(!_locationManager)
                        {
                            _locationManager = [[CLLocationManager alloc] init];
            
                            if([_locationManager respondsToSelector:@selector(requestWhenInUseAuthorization)])
                            {
                                [_locationManager requestWhenInUseAuthorization];
                             }
            
                            //设置代理
                            [_locationManager setDelegate:self];
                            //设置定位精度
                            [_locationManager setDesiredAccuracy:kCLLocationAccuracyBest];
                            //设置距离筛选
                            [_locationManager setDistanceFilter:100];
                            [_locationManager startUpdatingHeading];
                        } 
                        else 
                        {
                            //开始定位
                            [_locationManager startUpdatingLocation];
                        }
               }
               else
               {
                   //提示用户打开定位权限
                   [SystemManager openSettingPagewithMessage:@"定位"];
               }
            }
            //用户已经授权
            else if (authStatus == kCLAuthorizationStatusAuthorizedAlways||authStatus == kCLAuthorizationStatusAuthorizedWhenInUse)
            {
                isAvalible = YES;
            
                if (authorizedBlock)
                {
                    authorizedBlock();
                }
            }
            //用户决绝授权
            else
            {
                //提示用户打开定位权限
                [SystemManager openSettingPagewithMessage:@"定位"];
            }
        }
    
    
        return isAvalible;
    
    }
    

    三、设置页面跳转

    Q:提示用户需要打开对应权限,能否可以直接跳转到对应开关页面?

    A:iOS8之后是可以的

    跳转到设置界面

    +(void)openSettingPagewithMessage:(NSString *)message
    {
        if (iOS8OrLater)
        {
             [[SystemManager shareManager] showSystemAlertwithTitle:@"提示" message:[NSString stringWithFormat:@"为了更好的体验功能,请到设置页面->隐私->%@,将XX对应开关开启",message] cancelButtonTitle:@"下次提醒" otherButtonTitles:@"去设置" baseController:nil resultBlock:^(NSInteger index) {
            
                if (index == 1)
                {
                    NSURL *url = [NSURL URLWithString:UIApplicationOpenSettingsURLString];
                    if ([[UIApplication sharedApplication] canOpenURL:url])
                    {
                        [[UIApplication sharedApplication] openURL:url];
                    }
                }
            
            }];
        
        }
        //iOS8以下
        else
        {
            [[SystemManager shareManager] showSystemAlertwithTitle:@"提示" message:[NSString stringWithFormat:@"为了更好的体验功能,请到设置页面->隐私->%@,将XX对应开关开启",message] cancelButtonTitle:@"我知道了" otherButtonTitles:nil baseController:nil resultBlock:nil];
        }
    
    }
    
    XX为App的名字
    

    四、结束语

    谢谢大家。
