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+>

+(BOOL)detectionPhotoState:(void(^)())authorizedBlock
 {
     BOOL isAvalible = NO;

     if (iOS8OrLater)
     {
         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
      {
          ALAuthorizationStatus authStatus = [ALAssetsLibrary authorizationStatus];
    
         //用户已经授权
         if (authStatus == ALAuthorizationStatusAuthorized)
         {
             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"];
         }
      }

      return isAvalible;

}

相机访问权限<支持7.0+>

+(BOOL)detectionCameraState:(void(^)())authorizedBlock
{
    BOOL isAvalible = NO;

    AVAuthorizationStatus authStatus = [AVCaptureDevice authorizationStatusForMediaType:AVMediaTypeVideo];
    
    //用户尚未授权
    if (authStatus == AVAuthorizationStatusNotDetermined)
    {
        [AVCaptureDevice requestAccessForMediaType:AVMediaTypeVideo 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
    {
        //提示用户开启相机权限
        [SystemManager openSettingPagewithMessage:@"相机"];
    
    }

    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;
        
            //提示用户开启通知权限
            [SystemManager openSettingPagewithMessage:@"通知"];
        }
        else
        {
            isAvalible = YES;
        }
    }


    return isAvalible;
}
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。
