Question

我使用以下代码录制视频。

    UIImagePickerController *m_objpicker;=[[UIImagePickerController alloc] init];
    m_objpicker.sourceType = UIImagePickerControllerSourceTypeCamera;           

    m_objpicker.mediaTypes = [NSArray arrayWithObject:(NSString *)kUTTypeMovie];

    // hide the camera controls
    //picker.showsCameraControls=NO;
    m_objpicker.delegate = self;
    //picker.allowsImageEditing = NO;
    m_objpicker.allowsEditing=NO;
    // and put our overlay view in
    //picker.cameraOverlayView=m_objOverlayView;
    [self presentModalViewController:m_objpicker animated:YES];

当我们完成录制时

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

    NSURL *m_objMediaURL=[info objectForKey:UIImagePickerControllerMediaURL];

    [m_objpicker dismissModalViewControllerAnimated:YES];

}

我的疑问是，如何将捕获的视频保存到我们指定的位置。另外如何使用 UISaveVideoAtPathToSavedPhotosAlbum。

我需要在代码中更改所有内容，以便将视频保存到指定位置

谢谢，

如果您想保存到手机上的相机胶卷照片/视频相册：

定义：

void UISaveVideoAtPathToSavedPhotosAlbum (
   NSString *videoPath,
   id completionTarget,
   SEL completionSelector,
   void *contextInfo
);

执行地点和方式：

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

{

.... code here .....

NSString* m_objMediaURL= [info objectForKey:UIImagePickerControllerMediaURL];

//remember to test that the video is compatible for saving to the photos album

UISaveVideoAtPathToSavedPhotosAlbum(m_objMediaURL, self, @selector(video:didFinishSavingWithError:contextInfo:), nil);

.... code here .....

}

除非您想要保存到我不推荐的应用程序包中，否则除了将其保存到相机胶卷re：location之外无法控制。

以相册形式保存视频：

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

NSString *tempFilePath = [[info objectForKey:UIImagePickerControllerMediaURL] path];

            if (_newMedia){
                        if ( UIVideoAtPathIsCompatibleWithSavedPhotosAlbum(tempFilePath))
                              {
                                // Copy it to the camera roll.
                                UISaveVideoAtPathToSavedPhotosAlbum(tempFilePath, self, @selector(video:didFinishSavingWithError:contextInfo:), (__bridge void *)(tempFilePath));
                                 }
                         }


-(void) video: (NSString *) videoPath
 didFinishSavingWithError: (NSError *) error
  contextInfo: (void *) contextInfo {


NSLog(@"Finished saving video with error: %@", error);

}
