我正在尝试构建一个应用程序，让用户可以在 GTalk 中自由添加表情符号（例如：P :) :( ...）。但是一旦用户输入字符，我就无法弄清楚处理和显示它们的确切方法。

请为此提出想法，因为任何形式的帮助都可能引发解决方案。

对于输入，您可以使用自定义按钮，使用表情符号的 unicode 表示设置它们的标题。Iphone 对此有本机支持。

[myButton setTitle:@"\ue415" forState:UIControlStateNormal];

要将其显示在文本框中，您必须将其作为字符串的单个字符处理，以便您可以将常规文本与表情符号连接起来。

此页面列出了完整的表情符号列表：http: //pukupi.com/post/1964/

编辑：您可以使用转换表

:) = \ue415 :( = \ue40e ....

您可以使用该转换表来使用图像而不是 unicode 字符，但如果您想在同一段落中合并文本和图像，则非常复杂。如果您想使用图像，这是使用属性列表的示例
