iOS 13 仅 Instagram 照片共享不起作用

Bas*_*tek 8 instagram swift ios13 xcode11

在 iOS 12.4 之前,将照片共享到 Instagram 提要(按照文档)的实现工作正常,但从 iOS 13 开始它不再起作用。

使用当前的实现 -UIDocumentInteractionController的 UTI 设置为"com.instagram.exclusivegram"和文件扩展名.igo- 根本没有可见的 Instagram 共享选项。当我将文件扩展名更改为.ig我可以在建议中看到 Instagram 共享选项。这种分享到提要的方式有效,但这不是预期的仅适用于 Instagram 的解决方案。

将 UTI 设置为"com.instagram.photo"不会改变任何东西。

当我点击“分享”按钮时,预期的行为是在下面看到可见的视图,而不需要额外的步骤。这可能是 Instagram 的错误,还是有其他方法可以为 iOS 13 实现它?

您应该将图像添加到照片库,然后将图像直接从它共享到 instagram

首先不要忘记将 NSPhotoLibraryAddUsageDescription 和 instagram 方案添加到您的 info.plist 中:

<key>NSPhotoLibraryAddUsageDescription</key>
<string>$(PRODUCT_NAME) wants to save pictures to your library</string>

<key>LSApplicationQueriesSchemes</key>
<array>
    <string>instagram</string>
</array>
