在开发安卓项目的时候经常对于常用的功能进行封装成控件来使用，一个是减少代码量，另一个看起来简洁，而对于苹果开发也喜欢封装成控件，然后再storyboard里面拖拽，对于IOS开发自己属于菜鸟级别所以代码质量不是很高，如果那里有问题，请指出，这里记录一个是备忘另一个希望多多交流。
这篇是自定义输入框，输入框在项目中经常用到，最常见的比如左边是label右边是textfield，效果图如下：
代码如下

import UIKit
class ViewController: UIViewController {
@IBOutlet weak var userName: TextFieldValidator!
@IBOutlet weak var userPasswd: TextFieldValidator!
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view,typically from a nib.
userName.initWithFrame("用户名",placeholder: "请输入用户名")
userName.setReturnKey(UIReturnKeyType.Next)
userPasswd.initWithFrame("密码",placeholder: "请输入用户密码")
userPasswd.setSecureTextEntry(true)
userPasswd.setReturnKey(UIReturnKeyType.Done)
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
}
注意点：
如何将自定义控件加入storyboard?
由于自定义控件不是系统控件，所以能直接在Xcode中拖拽，首先需要拖拽自定义的父类，比如这里继承的是UIView，所以从Xcode中拖拽一个UIView到storyboard中，然后将UIView的class设置为自定义控件名称
查看类中的所有方法的快捷键？
