iOS 相機 麥克風 照片 許可權的檢測與獲取

前期設定
iOS10 中需要在plist檔案中新增獲取許可權宣告,否則會崩潰,提示資訊如下:
[access] This app has crashed because it attempted to access privacy-sensitive data without a usage description. The app's Info.plist must contain an NSMicrophoneUsageDescription key with a string value explaining to the user how the app uses this data.
plist中的設定如下圖
1.檢測麥克風許可權
//檢查麥克風許可權
- (void) checkAudioStatus{
AVAuthorizationStatus authStatus = [AVCaptureDevice authorizationStatusForMediaType:AVMediaTypeAudio];
switch (authStatus) {
case AVAuthorizationStatusNotDetermined:
//沒有詢問是否開啟麥克風
self.audioStatus = @"AVAuthorizationStatusNotDetermined" ;
break;
case AVAuthorizationStatusRestricted:
//未授權,家長限制
self.audioStatus = @"AVAuthorizationStatusRestricted";
break;
case AVAuthorizationStatusDenied:
//玩家未授權
self.audioStatus = @"AVAuthorizationStatusDenied";
break;
case AVAuthorizationStatusAuthorized:
//玩家授權
self.audioStatus = @"AVAuthorizationStatusAuthorized";
break;
default:
break;
}
}
2.獲取麥克風許可權
[AVCaptureDevice requestAccessForMediaType:AVMediaTypeAudio completionHandler:^(BOOL granted) {
NSLog(@"%@",granted ? @"麥克風准許":@"麥克風不准許");
}];
3.檢測相機許可權
- (void) checkVideoStatus
{
AVAuthorizationStatus authStatus = [AVCaptureDevice authorizationStatusForMediaType:AVMediaTypeVideo];
switch (authStatus) {
case AVAuthorizationStatusNotDetermined:
//沒有詢問是否開啟相機
self.videoStatus = @"AVAuthorizationStatusNotDetermined";
break;
case AVAuthorizationStatusRestricted:
//未授權,家長限制
self.videoStatus = @"AVAuthorizationStatusRestricted";
break;
case AVAuthorizationStatusDenied:
//未授權
self.videoStatus = @"AVAuthorizationStatusDenied";
break;
case AVAuthorizationStatusAuthorized:
//玩家授權
self.videoStatus = @"AVAuthorizationStatusAuthorized";
break;
default:
break;
}
}
4.獲取相機許可權
//授權相機
- (void)videoAuthAction
{
[AVCaptureDevice requestAccessForMediaType:AVMediaTypeVideo completionHandler:^(BOOL granted) {
NSLog(@"%@",granted ? @"相機准許":@"相機不准許");
}];
}
5.檢測照片許可權
//檢查照片許可權
- (void) checkPhotoStauts{
PHAuthorizationStatus photoAuthorStatus = [PHPhotoLibrary authorizationStatus];
switch (photoAuthorStatus) {
case PHAuthorizationStatusAuthorized:
self.photoLibraryStatus = @"PHAuthorizationStatusAuthorized";
break;
case PHAuthorizationStatusDenied:
self.photoLibraryStatus = @"PHAuthorizationStatusDenied";
break;
case PHAuthorizationStatusNotDetermined:
self.photoLibraryStatus = @"PHAuthorizationStatusNotDetermined";
break;
case PHAuthorizationStatusRestricted:
self.photoLibraryStatus = @"PHAuthorizationStatusRestricted";
break;
default:
break;
}
}
6.獲取照片許可權
//授權照片
- (void)phontLibraryAction{
[PHPhotoLibrary requestAuthorization:^(PHAuthorizationStatus status) {
}];
}
