Question

我不打算将我的应用添加到“打开...”列表中，而是将列表本身添加到列表中。并将文件发送到另一个应用程序。

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/她可以使用每个设备上安装的任何应用程序打开该文件...

Answer 1

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;
}

Answer 2

查看UIDocumentInteractionController https://developer.apple.com/library/ios/#documentation/UIKit/Reference/UIDocumentInteractionController_class/Reference/Reference.html和https://developer.apple.com/library/ios/#documentation/FileManagement/Conceptual/DocumentInteraction_TopicsForIOS/Articles/OpeningSupportedFileTypes.html#//apple_ref/doc/uid/TP40010412-SW1

Answer 3

另一种选择：

使用UIActivityViewController版本

提供的iOS 6.0 >

//create instance with file URL
UIActivityViewController *activity = [[UIActivityViewController alloc] initWithActivityItems:@[fileURLHere] applicationActivities:nil];
//present it
[self presentViewController:activity animated:YES completion:NULL];

注意：使用UIDocumentInteractionController时可能会出现问题。查看uidocumentinteractioncontroller-stopped-working-ios-8
