AVAuthorizationStatus authStatus = [AVCaptureDevice authorizationStatusForMediaType:AVMediaTypeVideo];  

typedef NS_ENUM(NSInteger, AVAuthorizationStatus) {

AVAuthorizationStatusNotDetermined = 0, //点击允许访问时调用  //用户明确许可与否，媒体需要捕获，但用户尚未授予或拒绝许可。

AVAuthorizationStatusRestricted, 

AVAuthorizationStatusDenied,   //不允许

AVAuthorizationStatusAuthorized   //允许访问 

} NS_AVAILABLE_IOS(7_0);

 

麦克风权限检测：

//检测麦克风功能是否打开    [[AVAudioSessionsharedInstance]requestRecordPermission:^(BOOL granted) {        if (!granted)        {            [ViewUtilalertViewWithString:NSLocalizedString(@"麦克风功能未开启",nil)];        }        else        {                        [selfrecord:sender];        }    }];

 

相册权限检测：需要

 

#import <AssetsLibrary/AssetsLibrary.h> //导入此类和AssetsLibrary.framework框架

int author = [ALAssetsLibrary authorizationStatus];              NSLog(@"author type:%d",author);              if(author == ALAuthorizationStatusRestricted || author == ALAuthorizationStatusDenied) {                  // The user has explicitly denied permission for media capture.                  UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"无法使用相册"                                                                  message:@"请在iPhone的\"设置-隐私-照片\"中允许访问照片。"                                                                 delegate:self                                                        cancelButtonTitle:@"确定"                                                        otherButtonTitles:nil];                  [alert show];                  [alert release];                  return;
