ios swift模仿qq登陆界面,xml布局

主要想要实现一个模仿的登陆界面

代码:

} // 添加所有子控件
func addAllSubViews(){ /// 平铺背景

func onClick()
{ ///找回密码提示

}
/**

*/
override func touchesBegan(touches: NSSet, withEvent event: UIEvent)
{ self.QQNumber.resignFirstResponder()
self.PassNumber.resignFirstResponder()
} }

实现根据xml进行布局:

对xml解析类的封装:

NSXMLParser(data: data),这个有几种初始化的方法,但是string就不行,得转换成NSdata,还是比较蛋疼的
