在UITextField中获取对齐文本 [英] Getting Justified Text in UITextField

问题描述

如何使用UTTextField获得合理的文本。它确实有一个textAlignment属性。但是UITextAlignment常数只有左，右和中心对齐。

How do I get justified text with UTTextField. It does have an textAlignment property. But the UITextAlignment constant only has left, right, and center justification.

我想要的是Justified文本常见的文字处理应用程序与文本同时左右边缘。这是一个只读文本字段。

What I am seeking is the Justified text common in word processing app with text flush with both left and right edges. This is a read only text field.

我在几个iPhone应用程序中看到了它。所以看来我错过了一些东西。

I have seen it in few iPhone apps. So it seems I am missing something.

推荐答案

UILabel和UITextField不支持全对齐文本。如果你想要一个UITextField，你必须创建一个UITextField的子类，并重写 drawTextInRect：，将文本分割成单词，并使用 sizeWithFont：

UILabel and UITextField do not support full-justified text. If you want it for a UITextField, you would have to create a subclass of UITextField and override drawTextInRect:, splitting the text into words and using sizeWithFont: to figure out how to space them along each line.

我无法想象什么是值得的麻烦。

I cannot imagine what would be worth the trouble.
