iOS：启动包含多个收件人的邮件应用程序 [英] iOS: Launching Messages app with multiple recipients

问题描述

我尝试进行设置，以便我的用户可以向一组人发送文本。现在用电子邮件很简单，URL方案只是 mailto：//[e-mail],[e-mail] ，然后可以使用 openURL 方法。

I'm trying to set it up so my user can send a text to a group of people. Now with email it's simple, the URL scheme is just mailto://[e-mail],[e-mail] which can then be used with the openURL method.

当我来到短信时，我决定尝试 sms：// 2065555555,2061234567 但是这不工作（它只添加第一个数字）。在浏览Google之后，我发现一些旧线程声称使用URL方法不能向多个收件人发短信。

Naturally when it came to SMS I decided to try sms://2065555555,2061234567 however this doesn't work (it only adds the first number). After browsing Google a bit, I found some older threads claiming that texting to multiple recipients isn't possible using the URL method.

为了向多个人发送邮件，我已经开始向我的应用程序添加 MessageUI ，挂接了 MFMessageComposeViewControllerDelegate ，现在我可以发送同时向多个人发送消息。但是只有从我自己的应用程序，这不是我想要的。我希望在框架中有一些东西，这将允许我利用多个收件人的功能，然后在默认消息中启动它，但我找不到任何允许这样。

In order to send a message to multiple people, I've gone ahead and added MessageUI to my application, hooked up the MFMessageComposeViewControllerDelegate, and now I can send indeed send messages to multiple people at once. However only from within my own application, which is not what I want. I was hoping there'd be something in the framework that would allow me to take advantage of the multiple recipients functionality and then launch it in the default messenger, but I can't find anything that allows that.

因此，总之，有没有可能的方式，我可以编写我的应用程序来填充默认的消息应用程序与多个收件人？任何帮助将不胜感激，谢谢。

So, in short, is there any possible way I can code my app to populate the default Messages app with multiple recipients? Any help would be appreciated, thank you.

编辑：实际上我确定必须有一个方法来做，我只是检查了应用程序Cobook，他们允许

Actually I'm certain there must be a way to do it, I just checked the app Cobook and they allow the user to select contacts then launch the Messages app sending a "New Group MMS".

推荐答案

我发现这是一个很老的问题 - 但我发现最近做的方法，并在这里张贴：

I realize this is a very old question - but I discovered the way to do it recently, and posted about it here:

SMS WatchKit多个数字分隔符

虽然这个答案是watchkit具体的，url实际上是你要的。

While this answer is watchkit specific, the url is really what you are asking about.

ANSWER ：
I 找到一个晦涩的页面，给了我的答案。事实证明，它没有记录在任何地方我可以找到：

ANSWER: I found an obscure page that gave me the answer. Turns out it is not documented by Apple anywhere I could find:

    let urlSafeBody = messageBody.stringByAddingPercentEncodingWithAllowedCharacters(NSCharacterSet.URLHostAllowedCharacterSet())
    if let urlSafeBody = urlSafeBody, url = NSURL(string: "sms:/open?addresses=1-408-555-1212,1-408-555-2121,1-408-555-1221&body=\(urlSafeBody)") {
        WKExtension.sharedExtension().openSystemURL(url)
     }

b $ b

上述版本将打开Apple Watch上的消息应用程序，并预填充多个收件人。

The above version will open the messages app on the Apple Watch with multiple recipients pre-populated.

有 多页 表示不可能，但它是。 Hooray！

There are many pages that state it isn't possible, but it is. Hooray!
