iOS 应用部分权限控制

整理下iOS开发中常用的权限控制，只整理里一些常用的并不全。

#import typedef void (^AuthorizedFinishBlock)();  @interface LYAuthorizedMaster : NSObject   #pragma mark - 摄像头权限 +(BOOL)checkCameraAuthority; +(void)cameraAuthorityCheckSuccess:(AuthorizedFinishBlock)_success fail:(AuthorizedFinishBlock)_fail;  #pragma mark - 麦克风权限 +(BOOL)checkAudioAuthority; +(void)audioAuthorityCheckSuccess:(AuthorizedFinishBlock)_success fail:(AuthorizedFinishBlock)_fail;  #pragma mark - 相册权限 +(BOOL)checkAlbumAuthority; +(void)albumAuthorityCheckSuccess:(AuthorizedFinishBlock)_success fail:(AuthorizedFinishBlock)_fail;  #pragma mark - 推送通知权限 +(BOOL)checkPushNotificationAuthority; +(void)pushNotificationAuthorityCheckSuccess:(AuthorizedFinishBlock)_success fail:(AuthorizedFinishBlock)_fail;  #pragma mark - 推送通知权限 +(BOOL)checkLocationAuthority; +(void)locationAuthorityCheckSuccess:(AuthorizedFinishBlock)_success fail:(AuthorizedFinishBlock)_fail;  #pragma mark - 通讯录权限 +(BOOL)checkAddressBookAuthority; +(void)AddressBookAuthorityCheckSuccess:(AuthorizedFinishBlock)_success fail:(AuthorizedFinishBlock)_fail;

下面是.m文件

里面引入了很多库文件，也不是所用项目都会用到的，用不到的注掉就好。

#import "LYAuthorizedMaster.h" #import        //摄像头麦克风 必须 #import      //相册权限 #import        //位置权限 #import          //通讯录权限  #import "AppDelegate.h"  #define kAPPName [[[NSBundle mainBundle] infoDictionary] objectForKey:@"CFBundleName"]  @implementation LYAuthorizedMaster  #pragma mark - +(BOOL)checkAuthority:(AVAuthorizationStatus)_status{     return (_status == AVAuthorizationStatusAuthorized) || (_status == AVAuthorizationStatusNotDetermined); } +(void)showAlertController:(AuthorizedFinishBlock)_block device:(NSString *)_device{     UIAlertController *_alertC = [UIAlertController alertControllerWithTitle:@"没有权限" message:[NSString stringWithFormat:@"请开启‘%@’对 %@ 的使用权限",kAPPName,_device] preferredStyle:UIAlertControllerStyleAlert];     [_alertC addAction:[UIAlertAction actionWithTitle:@"取消" style:UIAlertActionStyleCancel handler:nil]];     [_alertC addAction:[UIAlertAction actionWithTitle:@"确定" style:UIAlertActionStyleDefault handler:^(UIAlertAction *action) {         [[UIApplication sharedApplication] openURL:[NSURL URLWithString:UIApplicationOpenSettingsURLString]];     }]];     [((AppDelegate *)[UIApplication sharedApplication].delegate).window.rootViewController presentViewController:_alertC animated:YES completion:_block]; }  #pragma mark - 摄像头权限 +(BOOL)checkCameraAuthority{     return [self checkAuthority:[AVCaptureDevice authorizationStatusForMediaType:AVMediaTypeVideo]]; } +(void)cameraAuthorityCheckSuccess:(AuthorizedFinishBlock)_success fail:(AuthorizedFinishBlock)_fail;{     if ([self checkCameraAuthority]) {         if (_success) {             _success();         }     }else{         [self showAlertController:_fail device:@"相机"];     } }  #pragma mark - 麦克风权限 +(BOOL)checkAudioAuthority{     return [self checkAuthority:[AVCaptureDevice authorizationStatusForMediaType:AVMediaTypeAudio]]; } +(void)audioAuthorityCheckSuccess:(AuthorizedFinishBlock)_success fail:(AuthorizedFinishBlock)_fail{     if ([self checkAudioAuthority]) {         if (_success) {             _success();         }     }else{         [self showAlertController:_fail device:@"麦克风"];     } }  #pragma mark - 相册权限 +(BOOL)checkAlbumAuthority{     return [ALAssetsLibrary authorizationStatus] == ALAuthorizationStatusAuthorized; } +(void)albumAuthorityCheckSuccess:(AuthorizedFinishBlock)_success fail:(AuthorizedFinishBlock)_fail; {     if ([self checkAlbumAuthority]) {         if (_success) {             _success();         }     }else{         [self showAlertController:_fail device:@"照片"];     } }  #pragma mark - 位置权限 +(BOOL)checkLocationAuthority {     return [CLLocationManager locationServicesEnabled]; } +(void)locationAuthorityCheckSuccess:(AuthorizedFinishBlock)_success fail:(AuthorizedFinishBlock)_fail{          if ([self checkLocationAuthority]) {         if (_success) {             _success();         }     }else{         [self showAlertController:_fail device:@"位置"];     } }  #pragma mark - 推送通知权限 +(BOOL)checkPushNotificationAuthority {     return [[UIApplication sharedApplication] currentUserNotificationSettings].types != UIUserNotificationTypeNone; } +(void)pushNotificationAuthorityCheckSuccess:(AuthorizedFinishBlock)_success fail:(AuthorizedFinishBlock)_fail{          if ([self checkAlbumAuthority]) {         if (_success) {             _success();         }     }else{         [self showAlertController:_fail device:@"通知"];     } }  #pragma mark - 通讯录权限 +(BOOL)checkAddressBookAuthority {     return ABAddressBookGetAuthorizationStatus() == kABAuthorizationStatusAuthorized || ABAddressBookGetAuthorizationStatus() == kABAuthorizationStatusNotDetermined; } +(void)AddressBookAuthorityCheckSuccess:(AuthorizedFinishBlock)_success fail:(AuthorizedFinishBlock)_fail{          if ([self checkAddressBookAuthority]) {         if (_success) {             _success();         }     }else{         [self showAlertController:_fail device:@"通讯录"];     } }

最后有些时会遇到不弹出权限提示，或需要在提示框增加详细描述的时候，需要手动在info.plist加一些字段。

NSLocationWhenInUseUsageDescription    位置权限 使用期间 状态

NSLocationAlwaysUsageDescription    位置权限 始终 状态

下面这些我并没有都试，所以也不知道是否正确....

NSLocationUsageDescription    用于访问位置权限

NSCalendarsUsageDescription    用于访问日历权限

NSContactsUsageDescription    用于访问联络人

NSPhotoLibraryUsageDescription    用于访问相册

NSRemindersUsageDescription    用于访问提醒
