如何使用UIImagePickerController为iPhone选择和录制视频？ [英] How do I pick and record video using UIImagePickerController for iPhone?

问题描述

我想从iPhone上选择一个视频，用于我在网上上传的应用程序。
我使用的是UIImagePickerController。

I want to pick a video from iPhone for my application for uploading on the Web. I am using the UIImagePickerController for it.

用于开启选择器

UIImagePickerController *imagePicker = [[UIImagePickerController alloc] init];
imagePicker.delegate = self;
imagePicker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
imagePicker.mediaTypes = [[NSArray alloc] initWithObjects:(NSString *)kUTTypeMovie, nil];
[self presentModalViewController:imagePicker animated:YES];

它打开照片库并仅显示电影类型内容。

我有以下问题：

It opens the photo library and only shows the movie type content.
Now I have the following questions:

• 如果我选择视频，然后准备播放，然后当我点击


• 由于我们在iphone中有单独的文件夹，那么我们如何打开视频文件夹？

如果我能够选择，那么如何获取视频详细信息，因为委托方法是

If I am able to choose then how do I get video detail as delegate method is

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingImage:(UIImage *)img editingInfo:(NSDictionary *)editInfo {

，并且它具有（UIImage *）img 参数。如何获得视频？

and it has (UIImage *)img parameter. How do I get it as video?

推荐答案

您使用的是错误的委托方法。 iOS 3.0引入了 imagePickerController：didFinishPickingMediaWithInfo：来替换 imagePickerController：didFinishPickingImage：editingInfo：。这个新方法接收NSDictionary，其包含与所选择的图像/视频相关的多个键值对;在您的情况下，您需要检查 UIImagePickerControllerMediaURL 的值。

You're using the wrong delegate method. iOS 3.0 introduced imagePickerController:didFinishPickingMediaWithInfo: to replace imagePickerController:didFinishPickingImage:editingInfo:. This new method receives an NSDictionary which contains a number of key-value pairs related to the chosen image/video; in your case, you'll want to check the value for UIImagePickerControllerMediaURL.
