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:
