    创建图像选择器

    //1. 判断是否可用
        if (![UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera]) {
            return;
        }
        
        //2. 创建图像选择器
        UIImagePickerController *picker = [UIImagePickerController new];
        
        //3. 设置类型
        picker.sourceType = UIImagePickerControllerSourceTypeCamera;
        
        //4. 设置媒体类型
        picker.mediaTypes = @[(NSString *)kUTTypeMovie];
        
        //5. 设置相机检测模式
        picker.cameraCaptureMode = UIImagePickerControllerCameraCaptureModeVideo;
        
        //6. 设置视频的质量
        picker.videoQuality = UIImagePickerControllerQualityTypeHigh;
        
        //7. 设置代理
        picker.delegate = self;
        
        //8. 模态弹出
        [self presentViewController:picker animated:YES completion:nil];
    

    处理代理方法 保存视频

    //UIImagePickerController 代理方法
    - (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary<NSString *,id> *)info
    {
        
        //1. 获取媒体类型
        NSString *mediaTyep = info[UIImagePickerControllerMediaType];
        
        //2. 判断是否是视频的媒体类型
        
        id url = info[UIImagePickerControllerMediaURL];
        
        if ([mediaTyep isEqualToString:(NSString *)kUTTypeMovie]) {
            if (self.mpC == nil) {
                self.mpC = [MPMoviePlayerController new];
                self.mpC.view.frame = self.view.bounds;
                [self.view addSubview:self.mpC.view];
            }
            self.mpC.contentURL = url;
            [self.mpC play];
        }
        
        //3. 保存视频
        if (picker.sourceType == UIImagePickerControllerSourceTypeCamera) {
            
            //3.1 创建ALAssetsLibrary对象
            ALAssetsLibrary *assetsLibrary = [ALAssetsLibrary new];
            
            //3.2 调用writeVideoAtPathToSavedPhotosAlbum即可
            //前面的URL, 需要传入要保存的视频的URL.
            [assetsLibrary writeVideoAtPathToSavedPhotosAlbum:url completionBlock:nil];
            
        }
        
        [picker dismissViewControllerAnimated:YES completion:nil];
    }
