在IOS应用程序中共享扩展 [英] Sharing Extensions in IOS Apps

问题描述

我是整个iOS编程的新手 - Swift。我想知道，如果我在xCode6中创建一个项目，然后我想分享一个我从我的项目中获取的图像，例如evernote，google驱动器，消息，电子邮件，facebook，twitter等等。

I am new to the overall iOS Programming - Swift. I am wondering that if I create a project in xCode6 and then I would like to share an image that I took from my project for example to evernote, google drive, messages, email, facebook, twitter,so on and so on.

那么，我该怎么做？是什么，我需要从xcode6为每个共享扩展启用，或者我需要实现swift代码来启用这些共享扩展？

So, how would I do that? Is it something, I need to enable from xcode6 for each sharing extension or I need to implement swift code to enable these sharing extensions?

我可能需要什么样的配置改变以获得共享扩展（如上所述）？或者项目中的代码更改是可能的？是否有任何示例或示例，其中包含我可以查看的说明，并了解它们如何在xcode6中实现。

What kind of configurations I might needs to change to get sharing extensions (mentioned above) enabled? Or what kind of code changes in a project are possible? Are there any examples or samples out there with the instructions that I can look into and see how they implement into xcode6.

我以前从未使用过共享扩展，所以任何可以分享的知识对我来说将是一个很好的资源。提前致谢！

I never work with the sharing extensions before, so any knowledge that can be shared will be a great resource for me. Thanks in advance!

推荐答案

使用Xcode共享模板 。

有很多在线教程知道如何使用Swift进行共享扩展，这里有一些和一些关于扩展你应该知道的好文章：

There is a lot of tutorials online to know how to make share extensions using Swift, here are some of them and some good articles about extensions you should know too :

即使您也可以通过以下方式在代码中执行此操作：

Even you could do it in code too in the following way:

@IBAction func shareSheet(sender: AnyObject){

    let firstActivityItem = "Hey, check out this mediocre site that sometimes posts about Swift!"

    let secondActivityItem : NSURL = NSURL(fileURLWithPath: "http://www.dvdowns.com/")!

    let activityViewController : UIActivityViewController = UIActivityViewController(
    activityItems: [firstActivityItem, secondActivityItem], applicationActivities: nil)

    activityViewController.excludedActivityTypes = [
      UIActivityTypePostToWeibo,
      UIActivityTypePrint,
      UIActivityTypeAssignToContact,
      UIActivityTypeSaveToCameraRoll,
      UIActivityTypeAddToReadingList,
      UIActivityTypePostToFlickr,
      UIActivityTypePostToVimeo,
      UIActivityTypePostToTencentWeibo
    ]

    self.presentViewController(activityViewController, animated: true, completion: nil)
}

以上代码仅适用于iPhone，因为对于iPad，您需要指定 sourceView 并按以下方式将其显示为弹出窗口：

The above code only works for iPhones because for iPad you need to specify the sourceView and show it as a popover in the following way:

activityViewController.popoverPresentationController?.sourceView = (sender as! UIButton) 

上面的行必须在你初始化 activityViewController 后放入，它应该工作。

The above line must be put in just after you init the activityViewController and it should be work.

我希望这能帮到你。
