定位权限 : #import < CoreLocation/CoreLocation.h>

//定位权限状态
    CLAuthorizationStatus status = [CLLocationManager authorizationStatus];

    if (status == kCLAuthorizationStatusRestricted) {

        return;

    }else if (status == kCLAuthorizationStatusNotDetermined){

        //请求用户授权
        [self.manager requestWhenInUseAuthorization];
    }else{

        //定位相关设置
        self.manager.delegate = self;
        self.manager.desiredAccuracy = kCLLocationAccuracyBest;
        self.manager.distanceFilter = kCLLocationAccuracyNearestTenMeters;

        //开始定位
         [self.manager startUpdatingLocation];
    }

相册权限 #import < Photos/Photos.h>

    PHAuthorizationStatus status = [PHPhotoLibrary authorizationStatus];

    switch (status) {
            //未决定
        case PHAuthorizationStatusNotDetermined:
        {
            [PHPhotoLibrary requestAuthorization:^(PHAuthorizationStatus status) {

                if (status == PHAuthorizationStatusRestricted ||
                    status == PHAuthorizationStatusDenied) {

                }else{

                    //打开相册
                    [self uploadOperationWithOperationStyle:JYUploadOperationStylePhoto];
                }
            }];
        }
            break;

            //拒绝
          case AVAuthorizationStatusRestricted:
        {
            //引导用户打开权限
            [NSObject alertShowForAuthorizationWithTarget:nil callBack:^{

                //打开用户设置
                [[UIApplication sharedApplication] openURL:[NSURL URLWithString:UIApplicationOpenSettingsURLString]];
            }];

        }
            break;

            //已经授权过
            case AVAuthorizationStatusAuthorized:
        {
        //打开相册
            [self uploadOperationWithOperationStyle:JYUploadOperationStylePhoto];
        }
            break;
        default:
            break;
    }

通讯录权限 #import < AddressBook/AddressBook.h>

    //    kABAuthorizationStatusNotDetermined = 0,  未决定
    //    kABAuthorizationStatusRestricted,  特殊原因禁止访问用户通讯录
    //    kABAuthorizationStatusDenied,   用户拒绝访问
    //    kABAuthorizationStatusAuthorized 已经授权访问
    //    倒数第二种除非用户在设置里主动打开。否则在APP里永远无法访问 。 只有第一种情况下，才会告知用户授权。

    //判断用户授权状态
    ABAuthorizationStatus state = ABAddressBookGetAuthorizationStatus();

    //判断   如果授权状态是未决定的，则请求授权
    if (state == kABAuthorizationStatusNotDetermined) {

        //请求
        //1.获取通讯录对象
        ABAddressBookRef addressBook = ABAddressBookCreateWithOptions(NULL, NULL);

        //2.请求授权 (用户决定后就会回调block)
        ABAddressBookRequestAccessWithCompletion(addressBook, ^(bool granted, CFErrorRef error) {

            if (granted) {
                NSLog(@"用户授权成功");
            }else{
                NSLog(@"用户授权失败");
            }
        });
    }

相机权限

//权限判断
    AVAuthorizationStatus  authStatus = [AVCaptureDevice authorizationStatusForMediaType:AVMediaTypeVideo];

    switch (authStatus) {
            //未决定状态
        case AVAuthorizationStatusNotDetermined:

        {
            [AVCaptureDevice requestAccessForMediaType:AVMediaTypeVideo completionHandler:^(BOOL granted) {

                //接收
                if (granted) {

                    [self takePhotos];
                }
            }];
        }
            break;
            //拒绝
          case AVAuthorizationStatusRestricted:
        {
            //alert提示用户去设置里打开权限
        }
            break;
            case AVAuthorizationStatusAuthorized:
        {
            [self takePhotos];
        }
            break;
        default:
            break;
    }

//拍照或录像
- (void)takePhotos
{
    UIImagePickerController *controller = [[UIImagePickerController alloc] init];

    controller.sourceType = UIImagePickerControllerSourceTypeCamera;// 设置类型

    NSString *requiredMediaType = ( NSString *)kUTTypeImage;

    NSString *requiredMediaType1 = ( NSString *)kUTTypeMovie;

    NSArray *arrMediaTypes=[NSArray arrayWithObjects:requiredMediaType, requiredMediaType1,nil];

    controller.mediaTypes = arrMediaTypes;


    // 设置录制视频的质量
    controller.videoQuality = UIImagePickerControllerQualityTypeHigh;

    //设置最长摄像时间
    controller.videoMaximumDuration = 10.f;

    //设置代理    回调方法 , 之前文章有写过 , 这里就不写了
    controller.delegate = self;

    [self presentViewController:controller animated:YES completion:nil];
}
//然后在代理方法中得到内容 ...

麦克风权限

    AVAudioSessionRecordPermission status = [[AVAudioSession sharedInstance]recordPermission];

    switch (status) {

            //未决定状态
        case AVAudioSessionRecordPermissionUndetermined:
        {
            [[AVAudioSession sharedInstance]requestRecordPermission:^(BOOL granted) {

                if (granted) {

                    //打开麦克风录音

                }
            }];
        }
            break;

            //已经取得权限
            case AVAudioSessionRecordPermissionGranted:

            //打开麦克风录音
            break;
        default:
            break;
