如何在iphone中以编程方式复制/粘贴功能？ [英] How to do copy/paste function programmatically in iphone?

问题描述

我有一个文本视图，在该视图中有一些文本和一个复制按钮，

I have a text-view with some text and a copy button in that view,

当用户输入一些文本并按下复制按钮时，它需要复制该文本并将该文本粘贴到他想要的任何地方。

When the user enters some text and presses the copy button, it needs to copy that text and paste that text wherever he wants.

我知道iOS中有一个默认的复制/粘贴菜单控制器，但我希望在按钮单击。我认为有 UIPasteboard 来执行此功能，但我不知道如何使用它。

I know there is a default copy/paste menu-controller in iOS, but I want to do this functionality in a button click. I think there is UIPasteboard to do this functionality, but I don't know how to use it.

推荐答案

要从按钮复制​​，请点击：

To copy from a button click:

- (IBAction)copy {
    UIPasteboard *pb = [UIPasteboard generalPasteboard];
    [pb setString:[textView text]];
}

从按钮点击粘贴：

- (IBAction)paste {
    UIPasteboard *pb = [UIPasteboard generalPasteboard];
    textView.text = [pb string];
}
