- 重写绘制行为
- 除了UITextField对象的风格选项,你还可以定制化UITextField对象,为他添加许多不同的重写方法,来改变文本字段的显示行为。这些方法都会返回一个CGRect结构,制定了文本字段每个部件的边界范围。以下方法都可以重写。
- – textRectForBounds: //重写来重置文字区域
- – drawTextInRect: //改变绘文字属性.重写时调用super可以按默认图形属性绘制,若自己完全重写绘制函数,就不用调用super了.
- – placeholderRectForBounds: //重写来重置占位符区域
- – drawPlaceholderInRect: //重写改变绘制占位符属性.重写时调用super可以按默认图形属性绘制,若自己完全重写绘制函数,就不用调用super了.
- – borderRectForBounds: //重写来重置边缘区域
- – editingRectForBounds: //重写来重置编辑区域
- – clearButtonRectForBounds: //重写来重置clearButton位置,改变size可能导致button的图片失真
- – leftViewRectForBounds:
- – rightViewRectForBounds:
