ios 录制视频

今天写录制视频，我记得一年前写过，但是记不住怎么写了，查下资料，网上各种坑，废了好久都没查到我想要的只是录像，没办法只好找以前旧项目了！写完后想想还是记到博客中，好下次忘了了再查看，也让别让少坑些！

       如果想只要录像功能不要拍照功能，需要导入MobileCoreServices.framework 并引入头文件

       #import <MobileCoreServices/UTCoreTypes.h>

        设置下mediaTypes 如何想只拍照 设置 kUTTypeImage

      

        imagePicker.mediaTypes = [[NSArray alloc] initWithObjects: (NSString *)  kUTTypeMovie  , nil];

        imagePicker.sourceType =UIImagePickerControllerSourceTypeCamera;

         imagePicker.modalTransitionStyle =UIModalTransitionStyleCoverVertical;

         imagePicker.videoMaximumDuration = 30.0f; //设置最长摄像时间

         imagePicker.videoQuality = UIImagePickerControllerQualityTypeMedium;   //设置摄像图像品质

         //imagePicker.mediaTypes =  [UIImagePickerController            availableMediaTypesForSourceType:UIImagePickerControllerSourceTypeCamera]; // 照相和录像都有，默认拍照

         imagePicker.mediaTypes = [[NSArray alloc] initWithObjects: (NSString *)  kUTTypeMovie  , nil]; //只有录像

-(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info

{

      NSString * mediaType = [info objectForKey:UIImagePickerControllerMediaType];

    if ( CFStringCompare(( __bridge CFStringRef)mediaType, kUTTypeMovie, 0) == kCFCompareEqualTo)

    {

    

        NSString *videoPath = (NSString *)[[info objectForKey:UIImagePickerControllerMediaURL]path];

        

        if (UIVideoAtPathIsCompatibleWithSavedPhotosAlbum(videoPath))

        {

           // 处理视频

            

        }

        

    }

    

   [picker dismissViewControllerAnimated:YES completion:^{

       

   }];

}
