ios - 通过 WhatsApp 分享图片，只需显示 WhatsApp 图标

Question

我使用这段代码，但它显示了其他应用程序。

NSURL *URL = [[NSBundle mainBundle] URLForResource:@"ABC" withExtension:@"png"];
if (URL)
{
   self.documentInteractionController = [UIDocumentInteractionController interactionControllerWithURL:URL];
   [self.documentInteractionController setDelegate:self];
   CGRect rect = self.view.frame;
   [self.documentInteractionController presentOpenInMenuFromRect:rect inView:self.view animated:YES];

如何只显示 WhatsApp 图标？

Answer 1

以下是 WhatsApp 开发人员文档:https://www.whatsapp.com/faq/iphone/23559013

这里是相关的部分:

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

因此，为了共享图像，您可以将 UIDocumentInteractionController 的 UTI 设置为 net.whatsapp.image 并附加扩展名 .wai 到你的文件路径。

此外，this question可能有一些有用的示例代码。
