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？我认为拍摄视频应该很容易。当我启动手机的“相机”应用程序时，我可以在视频和图片之间进行选择。它不应该也适用于我的应用程序吗？

Answer 1

问题是我尝试将模式设置为视频模式的方式。

我没有使用这个：而是

imagePickerController.cameraCaptureMode = UIImagePickerControllerCameraCaptureModeVideo;

将其更改为：

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

并且它有效。

Answer 2

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

添加到上面的答案，正如 Micko 提到的，您需要在项目中添加 MobileCoreServices.framework 并在 imagePickerController 中引用它。
如果你想在图像拍摄视图的工具栏下有一个开关，只需如下设置 mediaTypes delegate 即可：

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

现在，你可以同时进行静态图像拍摄和视频拍摄，享受吧！

Answer 4

Xcode 9 - Swift 4.x：

注意这些语句的顺序：

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

并且记得添加到 info.plist：

Answer 5

如果您使用 Swift，那么您必须添加 MobileCoreServices.framework 以及您尝试录制视频的以下模块！

import MobileCoreServices

那么总的来说你的代码会是这样的

    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 6

此方法将打开我的 iPod 4 中的视频库，而不是我的设备的摄像机。

有人能告诉我如何解决这个问题吗？我已经尝试了上述两种方法。

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

感谢

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

您的帮助。

Answer 7

在此处输入代码请尝试此操作，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);


                }
