iOS許可權問題

標籤：

判斷相機許可權：

NSString *mediaType = AVMediaTypeVideo;AVAuthorizationStatus authStatus = [AVCaptureDevice authorizationStatusForMediaType:mediaType];if(authStatus == AVAuthorizationStatusRestricted || authStatus == AVAuthorizationStatusDenied){                   //相機許可權受限制}

typedef NS_ENUM(NSInteger, AVAuthorizationStatus) {    AVAuthorizationStatusNotDetermined = 0,    請問是否授權訪問    AVAuthorizationStatusRestricted,     許可權都限制    AVAuthorizationStatusDenied,    拒絕訪問    AVAuthorizationStatusAuthorized     授權訪問} NS_AVAILABLE_IOS(7_0) __TVOS_PROHIBITED;

 

判斷相簿許可權：

if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 8.0){PHAuthorizationStatus status = [PHPhotoLibrary authorizationStatus];    if (status == PHAuthorizationStatusDenied || status == PHAuthorizationStatusRestricted) {        //相簿許可權受限制    }}else{    ALAuthorizationStatus status = [ALAssetsLibrary authorizationStatus];    if (status == ALAuthorizationStatusDenied || status == ALAuthorizationStatusRestricted) {         //相簿許可權受限制    }}

ALAuthorizationStatus 在iOS9之後廢棄了，PHAuthorizationStatus 是ios8新增的替代 ALAuthorizationStatus 的方法。

typedef NS_ENUM(NSInteger, PHAuthorizationStatus) {    PHAuthorizationStatusNotDetermined = 0,     PHAuthorizationStatusRestricted,           PHAuthorizationStatusDenied,            PHAuthorizationStatusAuthorized        } NS_AVAILABLE_IOS(8_0);

typedef NS_ENUM(NSInteger, ALAuthorizationStatus) {    ALAuthorizationStatusNotDetermined     ALAuthorizationStatusRestricted     ALAuthorizationStatusDenied     ALAuthorizationStatusAuthorized } NS_DEPRECATED_IOS(6_0, 9_0, "Use PHAuthorizationStatus in the Photos framework instead");
