如何使用“打开...” iOS应用程序的功能？ [英] How to use "open in..." feature to iOS app?

问题描述

我不打算将我的应用添加到打开...列表中，但是要获取列表本身。并将文件发送到另一个应用程序。

I'm not looking to add my app to the "open in..." list, but to get the list itself. And sending the file to another app.

我正在开发内部通信应用程序，因此当用户收到文件附件时，他/她可以使用任何应用程序打开该文件安装在每个设备上......

I'm working on internal communication app, so when user receive a file attachment, s/he can open the file with whatever app is installed on each devices...

推荐答案

UIDocumentInteractionController *controller = [UIDocumentInteractionController interactionControllerWithURL:[NSURL fileURLWithPath:appFile]];
        self.controller.delegate = self;
CGRect navRect = self.view.frame;
[self.controller presentOptionsMenuFromRect:navRect inView:self.view animated:YES];

实施以下 UIDocumentInteractionControllerDelegate 方法

#pragma mark - UIDocumentInteractionControllerDelegate

//===================================================================
- (UIViewController *)documentInteractionControllerViewControllerForPreview:(UIDocumentInteractionController *)controller
{
    return self;
}

- (UIView *)documentInteractionControllerViewForPreview:(UIDocumentInteractionController *)controller
{
    return self.view;
}

- (CGRect)documentInteractionControllerRectForPreview:(UIDocumentInteractionController *)controller
{
    return self.view.frame;
}
