推荐答案

• 您的选择器视图应包含两个部分.
• 第一个组件中的行数应该是字体系列列表中项目的计数.
• 第二个组件中的行数应该是您希望提供的大小选项的数量.

这些数字由选择器视图控制数据源.该协议中只有两种方法.

These numbers are controlled by the picker view datasource. There are only two methods in this protocol.

• 每行的标题应该是列表中相关索引处的字体系列名称，或者是字体大小"选项.

这在选择器视图中涵盖了委托方法pickerView:titleForRow:forComponent:

This is covered by the picker view delegate method pickerView:titleForRow:forComponent:

您的数据源和委托通常是同一对象，通常是呈现选择器的视图控制器.

Your datasource and delegate are typically the same object, usually the view controller that is presenting the picker.
