plist文件里面添加，Privacy - Photo Library Usage Description，Value值为描述，弹出的提示框会显示出来。

升到iOS10之后，需要设置权限的有：

麦克风权限：Privacy - Microphone Usage Description 是否允许此App使用你的麦克风？
相机权限： Privacy - Camera Usage Description 是否允许此App使用你的相机？
相册权限： Privacy - Photo Library Usage Description 是否允许此App访问你的媒体资料库？
通讯录权限： Privacy - Contacts Usage Description 是否允许此App访问你的通讯录？
蓝牙权限：Privacy - Bluetooth Peripheral Usage Description 是否许允此App使用蓝牙？
语音转文字权限：Privacy - Speech Recognition Usage Description 是否允许此App使用语音识别？
日历权限：Privacy - Calendars Usage Description
定位权限：Privacy - Location When In Use Usage Description
定位权限: Privacy - Location Always Usage Description
位置权限：Privacy - Location Usage Description
媒体库权限：Privacy - Media Library Usage Description
健康分享权限：Privacy - Health Share Usage Description
健康更新权限：Privacy - Health Update Usage Description
运动使用权限：Privacy - Motion Usage Description
音乐权限：Privacy - Music Usage Description
提醒使用权限：Privacy - Reminders Usage Description
Siri使用权限：Privacy - Siri Usage Description
电视供应商使用权限：Privacy - TV Provider Usage Description
视频用户账号使用权限：Privacy - Video Subscriber Account Usage Description

权限的plist

    <key>NSAppleMusicUsageDescription</key> <string>App需要您的同意,才能访问媒体资料库</string> <key>NSBluetoothPeripheralUsageDescription</key> <string>App需要您的同意,才能访问蓝牙</string> <key>NSCalendarsUsageDescription</key> <string>App需要您的同意,才能访问日历</string> <key>NSCameraUsageDescription</key> <string>App需要您的同意,才能访问相机</string> <key>NSHealthShareUsageDescription</key> <string>App需要您的同意,才能访问健康分享</string> <key>NSHealthUpdateUsageDescription</key> <string>App需要您的同意,才能访问健康更新 </string> <key>NSLocationAlwaysUsageDescription</key> <string>App需要您的同意,才能始终访问位置</string> <key>NSLocationUsageDescription</key> <string>App需要您的同意,才能访问位置</string> <key>NSLocationWhenInUseUsageDescription</key> <string>App需要您的同意,才能在使用期间访问位置</string> <key>NSMicrophoneUsageDescription</key> <string>App需要您的同意,才能访问麦克风</string> <key>NSMotionUsageDescription</key> <string>App需要您的同意,才能访问运动与健身</string> <key>NSPhotoLibraryUsageDescription</key> <string>App需要您的同意,才能访问相册</string> <key>NSRemindersUsageDescription</key> <string>App需要您的同意,才能访问提醒事项</string>

从ios7开始，用户可以在设置->隐私->中开启或关闭某些系统权限，比如访问相册，相机 ，通讯录，地图，麦克风等。因此，在我们的程序中，如果要访问系统的某些功能，则最好判断一下权限是否开启。否则用户不能正常使用，也一头雾水，还以为程序出错了。

 

访问摄像头：

需要导入

 

#import <AVFoundation/AVFoundation.h>

 

1.  
   if(isIOS7AndLater) {
2.  
    
3.  
   NSString *mediaType = AVMediaTypeVideo;// Or AVMediaTypeAudio
4.  
   AVAuthorizationStatus authStatus = [AVCaptureDevice authorizationStatusForMediaType:mediaType];
5.  
   NSLog(@"---cui--authStatus--------%d",authStatus);
6.  
   // This status is normally not visible—the AVCaptureDevice class methods for discovering devices do not return devices the user is restricted from accessing.
7.  
   if(authStatus ==AVAuthorizationStatusRestricted){
8.  
   NSLog(@"Restricted");
9.  
   } else if(authStatus == AVAuthorizationStatusDenied){
10.  
    // The user has explicitly denied permission for media capture.
11.  
    NSLog(@"Denied"); //应该是这个，如果不允许的话
12.  
    UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"提示"
13.  
    message: @"请在设备的"设置-隐私-相机"中允许访问相机。"
14.  
    delegate: self
15.  
    cancelButtonTitle: @"确定"
16.  
    otherButtonTitles: nil];
17.  
    [alert show];
18.  
    [alert release];
19.  
    return;
20.  
    }
21.  
    else if(authStatus == AVAuthorizationStatusAuthorized){//允许访问
22.  
    // The user has explicitly granted permission for media capture, or explicit user permission is not necessary for the media type in question.
23.  
    NSLog(@"Authorized");
24.  
     
25.  
    } else if(authStatus == AVAuthorizationStatusNotDetermined){
26.  
    // Explicit user permission is required for media capture, but the user has not yet granted or denied such permission.
27.  
    [ AVCaptureDevice requestAccessForMediaType:mediaType completionHandler:^(BOOL granted) {
28.  
    if(granted){//点击允许访问时调用
29.  
    //用户明确许可与否，媒体需要捕获，但用户尚未授予或拒绝许可。
30.  
    NSLog(@"Granted access to %@", mediaType);
31.  
    }
32.  
    else {
33.  
    NSLog(@"Not granted access to %@", mediaType);
34.  
    }
35.  
     
36.  
    }];
37.  
    } else {
38.  
    NSLog(@"Unknown authorization status");
39.  
    }
40.  
    }

麦克风权限检测：

 

1.  
   //检测麦克风功能是否打开
2.  
   [[ AVAudioSessionsharedInstance]requestRecordPermission:^(BOOL granted) {
3.  
   if (!granted)
4.  
   {
5.  
   [ViewUtilalertViewWithString: NSLocalizedString(@"麦克风功能未开启",nil)];
6.  
   }
7.  
   else
8.  
   {
9.  
    
10.  
    [selfrecord:sender];
11.  
    }
12.  
    }];

相册权限检测：需要

 

#import <AssetsLibrary/AssetsLibrary.h> //导入此类和AssetsLibrary.framework框架

 

1.  
   int author = [ALAssetsLibrary authorizationStatus];
2.  
   NSLog(@"author type:%d",author);
3.  
   if(author == ALAuthorizationStatusRestricted || author == ALAuthorizationStatusDenied) {
4.  
   // The user has explicitly denied permission for media capture.
5.  
   UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"无法使用相册"
6.  
   message: @"请在iPhone的\"设置-隐私-照片\"中允许访问照片。"
7.  
   delegate: self
8.  
   cancelButtonTitle: @"确定"
9.  
   otherButtonTitles: nil];
10.  
    [alert show];
11.  
    [alert release];
12.  
    return;

 

 

ALAssetsLibrary详解

 

ALAssetsLibrary类是代表系统中整个资源库，使用它可以访问资源库中的资源和保存照片，视频等功能。

    _library = [[ALAssetsLibrary alloc]init];
    //判断当前应用是否能访问相册资源
    /*
     typedef NS_ENUM(NSInteger, ALAuthorizationStatus) {
     ALAuthorizationStatusNotDetermined = 0, 用户尚未做出了选择这个应用程序的问候
     ALAuthorizationStatusRestricted,        此应用程序没有被授权访问的照片数据。可能是家长控制权限。

     ALAuthorizationStatusDenied,            用户已经明确否认了这一照片数据的应用程序访问.
     ALAuthorizationStatusAuthorized         用户已授权应用访问照片数据.
     }
     */

 

    int author = [ALAssetsLibrary authorizationStatus];
    NSLog(@"author type:%d",author);

 

    //关闭监听共享照片流产生的频繁通知信息
    [ALAssetsLibrary disableSharedPhotoStreamsSupport];
    
    //创建一个相册到相册资源中，并通过block返回创建成功的相册ALAssetsGroup
    [_library addAssetsGroupAlbumWithName:@"test" resultBlock:^(ALAssetsGroup *group) {
        //NSString *const ALAssetsGroupPropertyName;
        //NSString *const ALAssetsGroupPropertyType;
        //NSString *const ALAssetsGroupPropertyPersistentID;
        //NSString *const ALAssetsGroupPropertyURL;
        //查看相册的名字
        NSLog(@"ALAssetsGroupPropertyName:%@",[group valueForProperty:ALAssetsGroupPropertyName]);
        //查看相册的类型
        NSLog(@"ALAssetsGroupPropertyType:%@",[group valueForProperty:ALAssetsGroupPropertyType]);
        //查看相册的存储id
        NSLog(@"ALAssetsGroupPropertyPersistentID:%@",[group valueForProperty:ALAssetsGroupPropertyPersistentID]);
        //查看相册存储的位置地址
        NSLog(@"ALAssetsGroupPropertyURL:%@",[group valueForProperty:ALAssetsGroupPropertyURL]);
        groupURL = [group valueForProperty:ALAssetsGroupPropertyURL];

    } failureBlock:^(NSError *error) {
        
    }];

新添加了一个名为test的相册

  [NSThread sleepForTimeInterval:0.5];
    //通过url地址在相册资源中获取该地址的资源文件ALAsset，有可能是相片或视频
    [_library assetForURL:[NSURL URLWithString:@""] resultBlock:^(ALAsset *asset) {
        /*
         NSString *const ALAssetPropertyType;
         NSString *const ALAssetPropertyLocation;
         NSString *const ALAssetPropertyDuration;
         NSString *const ALAssetPropertyOrientation;
         NSString *const ALAssetPropertyDate;
         NSString *const ALAssetPropertyRepresentations;
         NSString *const ALAssetPropertyURLs;
         NSString *const ALAssetPropertyAssetURL;
         */
        //查看资源的地理位置信息
        NSLog(@"ALAssetPropertyLocation:%@",[asset valueForProperty:ALAssetPropertyLocation]);
        //如果资源是视频，查看视频的时长
        NSLog(@"ALAssetPropertyDuration:%@",[asset valueForProperty:ALAssetPropertyDuration]);
        //查看资源的方向，图片的旋转方向
        NSLog(@"ALAssetPropertyOrientation:%@",[asset valueForProperty:ALAssetPropertyOrientation]);
        //查看资源的创建时间
        NSLog(@"ALAssetPropertyDate:%@",[asset valueForProperty:ALAssetPropertyDate]);
        //查看资源的描述信息
        NSLog(@"ALAssetPropertyRepresentations:%@",[asset valueForProperty:ALAssetPropertyRepresentations]);
        NSLog(@"ALAssetPropertyURLs:%@",[asset valueForProperty:ALAssetPropertyURLs]);
        //查看资源的url路径
        NSLog(@"ALAssetPropertyAssetURL:%@",[asset valueForProperty:ALAssetPropertyAssetURL]);
    } failureBlock:^(NSError *error) {
        
    }];
    //通过url地址获取相册资源中的一个相册
    [_library groupForURL:groupURL resultBlock:^(ALAssetsGroup *group) {
        NSLog(@"ALAssetsGroupPropertyName:%@",[group valueForProperty:ALAssetsGroupPropertyName]);
    } failureBlock:^(NSError *error) {
    
    }];
    //根据选择的类型遍历相册资源中的相对应类型的所有相册，其中stop行参是指针，表示是否停止迭代，当赋值为false则停止
    /*
     enum {
     ALAssetsGroupLibrary        = (1 << 0),
