How can I draw a button with quartz that has exactly the same style as a UIBarButtonItem. The button should be able to show different colors. I downloaded the Three20 project, but this project is really complex, you'd need a lot of time to overlook the whole framework. I just want to draw a custom UIBarButtonItem.

推荐答案

如果您使用 Three20 库，我猜 TTButton 的工具栏按钮"样式就是您想要的.TTButton 是 UIButton 的子类，但它允许您在创建网页时像使用 css 一样应用样式.

If you are using the Three20 library, I guess TTButton's "toolbarButton" style is what you want. TTButton is a sub-class of UIButton, but it allows you to apply styles just like using css while creating a webpage.

要创建像 UIBarButtonItem 这样的按钮，只需调用

To create a button like a UIBarButtonItem, just call

[TTButton buttonWithStyle:@"toolbarButton:" title:@"Title"]

您可能需要保留它，因为按钮是一个自动释放对象.

You may need to retain it since the button is an auto-release object.
