如何自定义UIActivityViewController共享菜单的示例？ [英] Example of how to customize UIActivityViewController share menu?

问题描述

是否有一个如何使用我自己的图标和 IBAction 自定义 UIActivityViewController 共享菜单的示例？

我见过这个......

   - （id）initWithActivityItems :( NSArray *）activityItems applicationActivities：（NSArray *）applicationActivities; 
  

但我还没有让它工作。

解决方案

您首先需要继承 UIActivity 。

然后你需要覆盖某些方法，包括 activityImage 来设置图标和 performActivity 用于执行操作（在您的问题中称为IBAction）。

如果不是静默执行操作，首先需要进一步用户交互和自定义活动的信息（例如，像标准UIActivity的Twitter帖子），你应该覆盖 activityViewController 而不是 performActivity 。

在你有 UIActivity 的子类后（例如， MyActivity ），你应该创建一个 MyActivity 的实例，并使它成为你传递给的 applicationActivities 数组的一个元素 initWithActivityItems：applicationActivities：。

看看 UIActivity的文档，确切地说明了在子类化和图标要求时需要覆盖的内容。 / p>

希望这会有所帮助。

Is there an example of how to customize UIActivityViewController share menu with my own icon and IBAction?

I have seen this...

- (id)initWithActivityItems:(NSArray *)activityItems applicationActivities:(NSArray *)applicationActivities;

but I have not gotten it to work yet.

解决方案

You first need to subclass UIActivity.

Then you need to override certain methods, including activityImage for setting the icon and performActivity for performing the action (what you call "IBAction" in your question).

If instead of performing the action silently, you first need further user interaction and info for your custom activity (e.g., like the Twitter post for the standard UIActivity), you should override activityViewController rather than performActivity.

After you have subclassed UIActivity (as, e.g, MyActivity), you should create an instance of MyActivity and make it an element of the applicationActivities array that you pass to initWithActivityItems:applicationActivities:.

Have a look at the documentation for UIActivity for exactly what you need to override when subclassing and for icon requirements.

Hope this helps a little.
