重寫繪制行為
除了UITextField對(duì)象的風(fēng)格選項(xiàng)澈蟆，你還可以定制化UITextField對(duì)象，為他添加許多不同的重寫方法卓研，來改變文本字段的顯示行為趴俘。這些方法都會(huì)返回一個(gè)CGRect結(jié)構(gòu)，制定了文本字段每個(gè)部件的邊界范圍鉴分。以下方法都可以重寫哮幢。
– textRectForBounds: //重寫來重置文字區(qū)域
– drawTextInRect: //改變繪文字屬性.重寫時(shí)調(diào)用super可以按默認(rèn)圖形屬性繪制,若自己完全重寫繪制函數(shù)，就不用調(diào)用super了.

– borderRectForBounds: //重寫來重置邊緣區(qū)域
– editingRectForBounds: //重寫來重置編輯區(qū)域
