使用UIPasteBoard（Swift）复制图像 [英] Copy Image with UIPasteBoard (Swift)

问题描述

我最近看到这个项目，用户可以从自定义键盘点击GIF，他们会看到一个复制的工具。我有一个问题：

I recently saw this project in which a user can tap on a GIF from a custom keyboard and they would see a "copied" toolip appear. I have one question:

• 如何在产品中重现此工具提示 GIF教程？

• How does one reproduce this tooltip in the products GIF-Tutorial?

任何人都可以给我一些示例代码使用。我理解如何使用UIPasteboard和它的功能，但我不能让它工作，当我在这个函数中添加UTI类型public.png：（我注意到在Objective-c它的@ public.png ，但我放置了public.png我找不到在线为这个源）

Could anyone give me some sample code to work with. I understand how to use UIPasteboard and it's functions, but I can't seem to get it to work when I put in the UTI type "public.png" in this function: (I noticed in Objective-c it's "@public.png", but I placed "public.png" I couldn't find a source online for this)

 let imageURL = NSString(string:NSBundle.mainBundle().pathForResource("test", ofType: "png")!)
        var data = NSData(contentsOfURL: NSURL(string:imageURL)!)
        UIPasteboard.generalPasteboard().setData(data!, forPasteboardType: "public.png")

推荐答案

尝试使用此代码：

let image = UIImage(named: "myimage.png")
UIPasteboard.generalPasteboard().image = image;
