iOS相册权限、相机权限、麦克风权限 ios

相册权限 iOS8之后加入了PhotoKit，使用需要

#import

权限类型

typedef NS_ENUM(NSInteger, PHAuthorizationStatus) { PHAuthorizationStatusNotDetermined = 0, // 未询问用户是否授权 PHAuthorizationStatusRestricted, // 未授权，例如家长控制 PHAuthorizationStatusDenied, // 未授权，用户拒绝造成的 PHAuthorizationStatusAuthorized// 已授权}

权限检测

PHAuthorizationStatus photoAuthStatus = [PHPhotoLibrary authorizationStatus]; if (photoAuthStatus == PHAuthorizationStatusNotDetermined) {// 未询问是否授权可以用下面的请求授权方法询问用户 }else if(photoAuthStatus == PHAuthorizationStatusRestricted || photoAuthStatus == PHAuthorizationStatusDenied) {// 未授权 }else{// 已授权 }

请求授权

[PHPhotoLibrary requestAuthorization:^(PHAuthorizationStatus status) { if (status == PHAuthorizationStatusAuthorized) { // 用户同意授权 }else { // 用户拒绝授权 }

相机&麦克风权限首先

#import

其次 【iOS相册权限、相机权限、麦克风权限】相机对应AVMediaTypeVideo
麦克风对应AVMediaTypeAudio

权限类型

typedef NS_ENUM(NSInteger, AVAuthorizationStatus) { AVAuthorizationStatusNotDetermined = 0,// 未询问用户是否授权 AVAuthorizationStatusRestricted,// 未授权，例如家长控制 AVAuthorizationStatusDenied,// 未授权，用户拒绝造成的 AVAuthorizationStatusAuthorized// 已授权}

权限检测

AVAuthorizationStatus videoAuthStatus = [AVCaptureDevice authorizationStatusForMediaType:AVMediaTypeVideo]; if (videoAuthStatus == AVAuthorizationStatusNotDetermined) {// 未询问用户是否授权 }else if(videoAuthStatus == AVAuthorizationStatusRestricted || videoAuthStatus == AVAuthorizationStatusDenied) {// 未授权 }else{// 已授权 }
