iPhone视频录制：“cameraCaptureMode 1不可用，因为mediaTypes确实包含public.movi​​e”

Question

我尝试录制视频。 我收到的消息来自设备上的以下代码：

    UIImagePickerController *imagePickerController = [[UIImagePickerController alloc] init];
    imagePickerController.sourceType = UIImagePickerControllerSourceTypeCamera;
    imagePickerController.allowsEditing = YES;
    imagePickerController.cameraCaptureMode = UIImagePickerControllerCameraCaptureModeVideo;
    imagePickerController.delegate = self;
    [self presentModalViewController:imagePickerController animated:YES];
    [imagePickerController release];

有什么想法吗？我认为录制视频应该很容易。当我启动手机的“相机”应用程序时，我可以选择视频和图片。它不应该也适用于我的应用程序吗？

Answer 1

问题在于我尝试将模式设置为视频模式。

而不是使用它：

imagePickerController.cameraCaptureMode = UIImagePickerControllerCameraCaptureModeVideo;

我把它更改为：

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

并且有效。

对于Swift 3.0，您必须添加以下行以支持照片和视频

import MobileCoreServices

  imagePicker.mediaTypes = [kUTTypeMovie as String, kUTTypeImage as String]

Answer 3

添加上面的答案，正如Micko所说，你需要在你的项目中添加MobileCoreServices.framework并在你的imagePickerController中引用它。 对于想要在图像拍摄视图中的工具栏下进行切换的用户，只需按如下方式设置mediaTypes委托：

imagePC.mediaTypes = [NSArray arrayWithObjects:(NSString *)kUTTypeMovie, (NSString *)kUTTypeImage, nil];

现在，您可以同时拍摄静态照片和视频，享受!!!

Answer 4

如果您正在使用Swift，那么您将不得不添加MobileCoreServices.framework以及您尝试录制视频的以下模块！

import MobileCoreServices

然后整体你的代码将是这样的

    var imag = UIImagePickerController()
    imag.delegate = self
    imag.sourceType = UIImagePickerControllerSourceType.Camera;
    imag.cameraDevice = UIImagePickerControllerCameraDevice.Rear //or Front
    imag.mediaTypes = [kUTTypeMovie];
    self.presentViewController(imag, animated: true, completion: nil)

Answer 5

Xcode 9 - Swift 4.x ：

注意这些陈述的顺序：

imagePickerController.mediaTypes = [kUTTypeMovie as String]
imagePickerController.cameraCaptureMode = .video

您还记得添加到info.plist:

此方法将在我的iPod中打开视频库4.不要使用我设备的摄像机。

有人会告诉我如何解决问题，我已经尝试了上述两种方式。

UIImagePickerController *imagePickerController = [[UIImagePickerController alloc] init];
    imagePickerController.sourceType = UIImagePickerControllerSourceTypeCamera;
    imagePickerController.allowsEditing = YES;
    imagePickerController.cameraCaptureMode = UIImagePickerControllerCameraCaptureModeVideo;
    imagePickerController.delegate = self;
    [self presentModalViewController:imagePickerController animated:YES];
    [imagePickerController release];

和

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

感谢您的帮助。

在这里输入代码请试试这个，这将打开摄像机

if([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera])
                {
                    UIImagePickerController *tmp_picker=[[UIImagePickerController alloc]init];
                    tmp_picker.sourceType=UIImagePickerControllerSourceTypeCamera;


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

                    tmp_picker.delegate=self;

                    [self presentModalViewController:tmp_picker animated:YES];
                    [tmp_picker release];
                    NSLog(@"button index is %i",buttonIndex);


                }
