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<Foundation/Foundation.h>typedefvoid(^AuthorizedFinishBlock)();@interfaceLYAuthorizedMaster:NSObject#pragmamark-摄像头权限+(BOOL)checkCameraAuthority;+(void)cameraAuthorityCheckSuccess:(AuthorizedFinishBlock)_successfail:(AuthorizedFinishBlock)_fail;#pragmamark-麦克风权限+(BOOL)checkAudioAuthority;+(void)audioAuthorityCheckSuccess:(AuthorizedFinishBlock)_successfail:(AuthorizedFinishBlock)_fail;#pragmamark-相册权限+(BOOL)checkAlbumAuthority;+(void)albumAuthorityCheckSuccess:(AuthorizedFinishBlock)_successfail:(AuthorizedFinishBlock)_fail;#pragmamark-推送通知权限+(BOOL)checkPushNotificationAuthority;+(void)pushNotificationAuthorityCheckSuccess:(AuthorizedFinishBlock)_successfail:(AuthorizedFinishBlock)_fail;#pragmamark-推送通知权限+(BOOL)checkLocationAuthority;+(void)locationAuthorityCheckSuccess:(AuthorizedFinishBlock)_successfail:(AuthorizedFinishBlock)_fail;#pragmamark-通讯录权限+(BOOL)checkAddressBookAuthority;+(void)AddressBookAuthorityCheckSuccess:(AuthorizedFinishBlock)_successfail:(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。

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
