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
}
}Rest就是我们信息展示的结构，现在新建一个类DataArray，把初始化的信息放到其中，代码如下：
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),
]
}
}
ViewController中的相关信息就没用了，我们可以删除掉，修改后的ViewController代码如下：
import UIKit
class ViewController: UIViewController,UITableViewDataSource,UITableViewDelegate {
var restArray = DataArray().dataArray
var tableView = UITableView()
override func viewDidLoad() {
super.viewDidLoad()
self.navigationItem.title = "cgGo"
tableView = UITableView(frame: CGRectMake(0, 0, 320, 568), style: UITableViewStyle.Plain)//定义一个tableview
self.view.addSubview(tableView)//不添加看不到
tableView.dataSource = self
tableView.delegate = self //之前是在storyboard中设置的，现在改为手动设置
tableView.registerClass(CustomTableViewCell.self, forCellReuseIdentifier: "Cell")
// Do any additional setup after loading the view, typically from a nib.
}
func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return restArray.count
}
func numberOfSectionsInTableView(tableView: UITableView) -> Int {
return 1;
}
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let identiString = "Cell" //代码复用
var cell = tableView.dequeueReusableCellWithIdentifier(identiString,forIndexPath : indexPath) as? CustomTableViewCell
if cell == nil {
cell = UITableViewCell(style: UITableViewCellStyle.Default, reuseIdentifier: identiString) as? CustomTableViewCell
}
var rest = restArray[indexPath.row]
var restName = rest.name
var restLocation = rest.location
var imageName = rest.image
var restType = rest.type
cell?.initWith(imageName, restName: restName, restLocation: restLocation, restType: restType)
if rest.isVisit{
cell?.accessoryType = .Checkmark
} else {
cell?.accessoryType = .None
}
return cell!
}
override func prefersStatusBarHidden() -> Bool { //隐藏上边栏中的电量、信号等信息
return true
}
func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
tableView.deselectRowAtIndexPath(indexPath, animated: true)
let callActionHandler = {(action:UIAlertAction!) -> Void in
let alertMessage = UIAlertController(title: "Service is unavalable", message: "You can choice another rest" , preferredStyle: UIAlertControllerStyle.Alert)
alertMessage.addAction(UIAlertAction(title: "ok", style: UIAlertActionStyle.Default, handler: nil))
self.presentViewController(alertMessage, animated: true, completion: nil)
}
let option = UIAlertController(title: nil, message: "What are you goning to do?", preferredStyle: UIAlertControllerStyle.ActionSheet)
//callAction
let callAction = UIAlertAction(title: "Call"+"180-123-\(indexPath.row)", style: UIAlertActionStyle.Default, handler: callActionHandler)//自定义的callActionHandler来响应点击的事件
//markAction
let markAction = UIAlertAction(title: "I'm here", style: UIAlertActionStyle.Default, handler: {
(action:UIAlertAction!) ->Void in
let cell = tableView.cellForRowAtIndexPath(indexPath)
cell?.accessoryType = UITableViewCellAccessoryType.Checkmark //对号
self.restArray[indexPath.row].isVisit = true
})
option.addAction(markAction)
//cancelAction
let cancelAction = UIAlertAction(title: "ok", style: UIAlertActionStyle.Cancel, handler: nil)
// self.presentViewController(option, animated: true, completion: nil)
let detail = DetailViewController()
self.navigationController?.pushViewController(detail, animated: true)
var image = restArray[indexPath.row].image
detail.imageName = image
option.addAction(cancelAction)
option.addAction(callAction)
}
func tableView(tableView: UITableView, heightForRowAtIndexPath indexPath: NSIndexPath) -> CGFloat {
return 80
}
func tableView(tableView: UITableView, commitEditingStyle editingStyle: UITableViewCellEditingStyle, forRowAtIndexPath indexPath: NSIndexPath) {
if editingStyle == .Delete {
self.restArray.removeAtIndex(indexPath.row)
}
self.tableView.deleteRowsAtIndexPaths([indexPath], withRowAnimation: UITableViewRowAnimation.Left)
}
func tableView(tableView: UITableView, editActionsForRowAtIndexPath indexPath: NSIndexPath) -> [AnyObject]? {
let shareAction = UITableViewRowAction(style: .Default, title: "Share", handler: {
(action: UITableViewRowAction!, indexPath: NSIndexPath!) -> Void in
let menu = UIAlertController(title: "Share Action", message: nil, preferredStyle: .ActionSheet)
let csdnAction = UIAlertAction(title: "csdn", style: .Default, handler: nil)
menu.addAction(csdnAction)
let cancelAction = UIAlertAction(title:"Cancel", style: .Cancel, handler: nil)
menu.addAction(cancelAction)
self.presentViewController(menu, animated: true, completion: nil)
})
let deleteAction = UITableViewRowAction(style: .Default, title: "Delete", handler: {
(action: UITableViewRowAction!,indexPath: NSIndexPath!) -> Void in
})
return [deleteAction, shareAction]
}
}
可以看到之前单个的数组被名为restArray的model取代了，在定义cel的代理方法中引用restArray实例，显示效果如图：
