UITextField笔记

borderStyle
The border style used by the text field.

@property(nonatomic) UITextBorderStyle borderStyle
Discussion
The default value for this property is UITextBorderStyleNone. If the value is set to the UITextBorderStyleRoundedRect style, the custom background image associated with the text field is ignored.

只有该属性为UITextBorderStyleNone时才可以给UITextField加背景
