如何从我的应用程序发送图像到WhatsApp？ [英] How send image to WhatsApp from my application?

问题描述

2013年7月，WhatsApp为我们的应用程序开放了他们的URL方案。我已经从我的应用程序发送文本到Whatsapp，但现在我想发送一个图像。如何将图像发送到Whatsapp？

我不知道怎么做。

谢谢。

解决方案

根据他们的文档，您需要使用 UIDocumentInteractionController 。要在文档控制器中选择性地仅显示Whatsapp（它呈现给用户，此时他们可以选择要分享的Whatsapp），按照他们的指示：

或者，如果您只想在应用程序列表中显示WhatsApp（而不是WhatsApp以及任何其他符合公共/ *的应用程序），您可以指定一个上述类型的文件，该文件使用扩展名保存WhatsApp：

  images  - «.wai»，类型为net.whatsapp.image 
视频 - «.wam»，类型为net.whatsapp.movi​​e 
音频文件 - «.waa»，类型为net.whatsapp.audio 
  

您需要将映像保存到磁盘，然后使用该文件URL创建 UIDocumentInteractionController 。 / p>

以下是一些示例代码：

  _documentController = [UIDocumentInteractionController interactionControllerWithURL： _图像文件URL] 
 _documentController.delegate = self; 
 _documentController.UTI = @net.whatsapp.image; 
 [_documentController presentOpenInMenuFromRect：CGRectZero inView：self.view animated：YES] 
  

In July 2013 WhatsApp opened their URL schemes for our apps. I have sent text to Whatsapp from my application, but now I would like send a image. How send a image to Whatsapp?

I'm not sure how do it.

Thank you.

解决方案

Per their documentation, you need to use UIDocumentInteractionController. To selectively display only Whatsapp in the document controller (it is presented to the user, at which point they can select Whatsapp to share to), follow their instructions:

Alternatively, if you want to show only WhatsApp in the application list (instead of WhatsApp plus any other public/*-conforming apps) you can specify a file of one of aforementioned types saved with the extension that is exclusive to WhatsApp:

images - «.wai» which is of type net.whatsapp.image
videos - «.wam» which is of type net.whatsapp.movie
audio files - «.waa» which is of type net.whatsapp.audio

You need to save the image to disk, and then create a UIDocumentInteractionController with that file URL.

Here is some example code:

_documentController = [UIDocumentInteractionController interactionControllerWithURL:_imageFileURL];
_documentController.delegate = self;
_documentController.UTI = @"net.whatsapp.image";
[_documentController presentOpenInMenuFromRect:CGRectZero inView:self.view animated:YES]
