推荐答案

我想你会在 UITextInputProtocol 。

有关更多高级别信息，请查看Apple的文本，Web和编辑指南，特别是在标题为UITextInput实现的指导教程的部分中。它讨论了如何在文本中创建索引位置，并询问他们最接近的文本位置。

For some more high level information, check out Apple's Text, Web and Editing Guide, specifically in the section titled "A Guided Tour of a UITextInput Implementation". It discusses how you can create indexed positions in text, and ask touches what text position they've landed nearest.

Apple引用了一个名为的预测样本SimpleTextInput ，但我似乎无法找到它。我会继续寻找。

Apple's references a sample projected called SimpleTextInput, but I can't seem to find it. I'll keep looking.
