推荐答案

Share Extension的UIViewController具有一个属性:

UIViewController of Share Extension have a property:

    NSExtensionContext *extensionContext;

NSExtensionContext具有一个属性:

NSExtensionContext have a property:

    NSArray *inputItems;

其中有一个NSExtensionItem类的索引为0的对象

Which have a 0-indexed object of NSExtensionItem class

接下来，NSExtension Item具有一个属性:

Next, NSExtension Item have a property:

    NSArray *attachments;

这是NSItemProvider类的对象数组，现在是时候阅读一些 NSItemProvider类的文档

Which is an array of objects of NSItemProvider class, and now it is time to go to read some documentation for NSItemProvider class
