Ios 在iPad中显示保存的视频

我想在popOver控制器的照片库中显示保存的视频，就像显示图像一样

如何在popOver controller中显示视频？

我的图像代码如下：

if ([self.popoverController isPopoverVisible]) {
        [self.popoverController dismissPopoverAnimated:YES];
        [popoverController release];
    } else {
        if ([UIImagePickerController isSourceTypeAvailable:
             UIImagePickerControllerSourceTypeSavedPhotosAlbum])
        {
            UIImagePickerController *imagePicker =
            [[UIImagePickerController alloc] init];
            imagePicker.delegate = self;
            imagePicker.sourceType =
            UIImagePickerControllerSourceTypePhotoLibrary;
            imagePicker.mediaTypes = [NSArray arrayWithObjects:
                                      (NSString *) kUTTypeImage,
                                      nil];
            imagePicker.allowsEditing = NO;

            self.popoverController = [[UIPopoverController alloc]
                                      initWithContentViewController:imagePicker];

            popoverController.delegate = self;


            [self.popoverController presentPopoverFromRect:CGRectMake(100, 100, 150, 100) inView:self.view permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];

            [imagePicker release];

帮我解决这个问题。

谢谢，您必须选择正确的媒体类型：

UIImagePickerController *imagePicker = [[UIImagePickerController alloc] init];
imagePicker.sourceType = UIImagePickerControllerSourceTypeSavedPhotosAlbum;

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

由于未捕获的异常“NSInvalidArgumentException”而终止应用程序，原因：“源2没有可用类型”

您是否在旧设备上测试？我在谷歌上搜索了一些答案：也可以试试这个：

myImagePickerController.mediaTypes=[UIImagePickerController可用于源类型的媒体类型：UIImagePickerController源类型Camera]由于未捕获的异常“NSInvalidArgumentException”而终止应用程序，原因是：“源2没有可用的类型”
