前言
目标就是方便的将xib写的视图 方便的封装成一个组件来用

使用方法
比如我们的xib名字为ZJUserPicView.xib
就必须建一个相同名字的类ZJUserPicView.swift并继承ZJXibView
ZJUserPicView.swift

| import UIKit
class ZJUserPicView: ZJXibView {
@IBOutlet weak var picImageView: UIImageView!
@IBOutlet weak var nameLabel: UILabel!
override func awakeFromNib() {
super.awakeFromNib()
}
}
|
ZJUserPicView.xib的File's Owner的Class指定为ZJUserPicView.swift
然后连接picImageView和nameLabel
这样ZJUserPicView就可以整体做一个组件来用了
