问题描述

在iOS 7中，支持通过第三方应用程序在短信中添加附件.

In iOS 7, there is support for adding attachments in sms messages via third party applications.

我想知道:

1. 支持哪些文件作为附件?例如.png，.pdf等.

1. What kind of files are supported as attachments? e.g. .png, .pdf etc.

我可以通过短信/彩信发送NSData吗?例如.dat格式

Can I send NSData through an sms/mms message? e.g. .dat format

这些邮件的收件人能否使用iOS的打开方式"功能在第三方应用程序中打开这些附件?

Would the recipient of these messages be able to open these attachments in third party applications using iOS's "Open In" feature?

推荐答案

MFMessageComposeViewController希望附件具有您要上传的图像类型的正确扩展名. 我通过测试PNG文件以及添加附件数据的以下变体进行了验证:

The MFMessageComposeViewController wants the attachment to have the correct extension for the type of image you're uploading. I verified by testing with a PNG file, and the following variations of adding the attachment data:

[messageController addAttachmentData:imgData typeIdentifier:@"public.data" filename:@"image"];
[messageController addAttachmentData:imgData typeIdentifier:@"public.data" filename:@"image.abc"];
[messageController addAttachmentData:imgData typeIdentifier:@"public.data" filename:@"image.png"];

仅最后一个选项有效. 我不需要更改typeIdentifier，尽管选择与数据类型匹配的UTI可能很有意义.

Only the last option worked. I didn't need to change the typeIdentifier, although it probably would make sense to choose a UTI that matches the type of data.
