Swift语言IOS8开发战记9.Data Model

上一话中实现了两个控制器间的传值，最终效果如图：

这是我们的主页面：

在ViewController中我们主页显示的内容是放到不同的数组中的：

var restaurantNames = ["cg1","cg2","cg3","cg4","cg5","cg6","cg7","cg8","cg9","cg10","cg11"]
    var restaurantImages =
    ["128.png","129.png","130.png","131.png","132.png","133.png","134.png","135.png","136.png","137.png","138.png","139.png","140.png"]

今天我们想要把主页面中的信息进行整合，反映到跳转页面中，这就要应用到程序中的Model。通过观察，我们每一行所展示的内容，格式上都是一样的，有图片有标题，现在我们把这个模型单独分离出来。新建一个数据模型，也就是一个cocoa touch class，命名为Rest，代码如下：

import UIKit

class Rest: NSObject {
    var name: String = ""
    var image: String = ""
    var location: String = ""
    var type: String = ""
    var isVisit: Bool = false
    init(name: String,image: String,location: String,type: String,isVisit: Bool){
    
    self.name = name
    self.image = image
    self.location = location
    self.type = type
    self.isVisit = isVisit
    }
}

import UIKit

class DataArray: NSObject {
    var tempArray = [Rest]() //临时变量
    var dataArray:[Rest] {
        get {
            return tempArray
        }
    }
    
    override init(){
        tempArray = [
     Rest(name: "cg1", image: "128.png", location: "xd1", type: "Cafe", isVisit: false),
     Rest(name: "cg2", image: "129.png", location: "xd2", type: "Cafe", isVisit: false),
     Rest(name: "cg3", image: "130.png", location: "xd3", type: "Tea", isVisit: false),
     Rest(name: "cg4", image: "131.png", location: "xd4", type: "Cafe", isVisit: false),
     Rest(name: "cg5", image: "132.png", location: "xd5", type: "Tea", isVisit: false),
     Rest(name: "cg6", image: "133.png", location: "xd6", type: "Cafe", isVisit: false),
     Rest(name: "cg7", image: "134.png", location: "xd7", type: "Cafe", isVisit: false),
     Rest(name: "cg8", image: "135.png", location: "xd8", type: "Cafe", isVisit: false),
     Rest(name: "cg9", image: "136.png", location: "xd9", type: "Cafe", isVisit: false),
     Rest(name: "cg10", image: "137.png", location: "xd10", type: "Cafe", isVisit: false),
     Rest(name: "cg11", image: "138.png", location: "xd11", type: "Tea", isVisit: false),
            
        ]
        
        
    }
    
}

        self.view.addSubview(tableView)//不添加看不到
