如何从ipad内置视频应用访问视频

Question

我正在制作一个应用程序，我想从iPad的视频中导入视频。

可以在iOS设备上访问视频应用吗？

注意我不是在谈论照片库或相机胶卷。

Answer 1

通过此代码，您可以获取设备的照片库视频，但不能获取内置视频应用。

目标C

-(BOOL)startMediaBrowserFromViewController:(UIViewController*)controller usingDelegate:(id )delegate {
    if (([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeSavedPhotosAlbum] == NO)
        || (delegate == nil)
        || (controller == nil)) {
        return NO;
    }
    UIImagePickerController *mediaUI = [[UIImagePickerController alloc] init];
    mediaUI.delegate = delegate;
    [mediaUI setMediaTypes:[NSArray arrayWithObject:(NSString *)kUTTypeMovie]];
    [controller presentViewController:mediaUI animated:YES completion:nil];
    return YES;
} 

Swift 4.2

func startMediaBrowser(from controller: UIViewController?, usingDelegate delegate: Any?) -> Bool {
    if (UIImagePickerController.isSourceTypeAvailable(.savedPhotosAlbum) == false) || (delegate == nil) || (controller == nil) {
        return false
    }
    let mediaUI = UIImagePickerController()
    mediaUI.delegate = delegate as? (UIImagePickerControllerDelegate & UINavigationControllerDelegate)
    mediaUI.mediaTypes = ["kUTTypeImage"]
    controller?.present(mediaUI, animated: true)
    return true
}
