import UIKit

var todos: [TodoModel] = []

func dateFromString(dateStr: String) -> NSDate? {

    let dateFormatter = NSDateFormatter()

    dateFormatter.dateFormat = "yyy-MM-dd"

    let date = dateFormatter.dateFromString(dateStr)

    return date

}

class ViewController: UIViewController, UITableViewDataSource {

    

    @IBOutlet weak var tableView: UITableView!

    

    override func viewDidLoad() {

        super.viewDidLoad()

        // Do any additional setup after loading the view, typically from a nib.

        todos = [TodoModel(id: "1", image: "child-selected", title: "1. 去游乐场", date: dateFromString("2014-11-2")!),

        TodoModel(id: "2", image: "shopping-cart-selected", title: "2. ", date: dateFromString("2014-10-28")!),

        TodoModel(id: "3", image: "phone-selected", title: "3. 打电话", date: dateFromString("2014-10-30")!),

        TodoModel(id: "4", image: "travel-selected", title: "4. Travel to Europe", date: dateFromString("2014-10-31")!),

        ]

    }

    override func didReceiveMemoryWarning() {

        super.didReceiveMemoryWarning()

        // Dispose of any resources that can be recreated.

    }

    //Implement UITableviewDataSource

    func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        //return 50

        return todos.count

    }

    
    func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {

        let cell = self.tableView.dequeueReusableCellWithIdentifier("todoCell")! as UITableViewCell

        
        var todo = todos[indexPath.row] as TodoModel

        

        //get control from tag

        var image = cell.viewWithTag(101) as! UIImageView

        var title = cell.viewWithTag(102) as! UILabel

        var date = cell.viewWithTag(103) as! UILabel

        

        image.image = UIImage(named: todo.image)

        title.text = todo.title

        

        let locale = NSLocale.currentLocale()

        let dateFormat = NSDateFormatter.dateFormatFromTemplate("yyyy-MM-dd", options: 0, locale: locale)

        let dateFormatter = NSDateFormatter()

        dateFormatter.dateFormat = dateFormat

        date.text = dateFormatter.stringFromDate(todo.date)

        

    

        return cell

    }

}
