我有一个关于uitableview的问题.我在uitableview中有一个水果列表,在右侧导航栏中有一个过滤按钮.当我们点击过滤按钮时,我们如何对水果列表进行排序.我该怎么做filterList函数.下面是code.please看看吧.

/* Fruit.swift */

import Foundation

class Fruit {
    var fruitName = ""

    init(fruitName: String) { self.fruitName = fruitName }

}


class FruitsListViewController: UIViewController, UITableViewDataSource, UITableViewDelegate {

    @IBOutlet var fruitList: UITableView!

    @IBOutlet var filterItem: UIBarButtonItem!

    var fruitArr:[Fruit] = Fruit

    override func viewDidLoad() {
        super.viewDidLoad()

        var barButton = UIBarButtonItem(title: "Filter", style: .Plain, target: self, action:"filterList") 
        self.navigationItem.rightBarButtonItem = barButton

        var fruits1 = Fruit(fruitName: "Apple" as String) 
        var fruits2 = Fruit(fruitName: "Mango" as String) 
        var fruits3 = Fruit(fruitName: "Banana" as String) 
        var fruits4 …

我有麻烦了.我想在导航栏标题中使用图像,但我收到一个错误,即"UIImage"不是"NSString"的子类型.在代码下面,看看它.

class Dashboard: UIViewController {

override func viewDidLoad() {
    super.viewDidLoad()
    self.navigationItem.title = UIImage(named: "logo.png")        
    // Do any additional setup after loading the view.
}

override func didReceiveMemoryWarning() {
    super.didReceiveMemoryWarning()
    // Dispose of any resources that can be recreated.
}

}

有人可以建议吗？谢谢!

我有一个日期"2014年9月18日星期四"的格式.当我点击"更改日期"按钮.我们如何在swift语言中自动选择datepicker中的这个日期.

我遇到了麻烦,任何人都可以建议如何在swift ios中获得动态文本域的价值？我该怎么做buttonTapped函数.看它

class ViewController: UIViewController {

override func viewDidLoad() {
    super.viewDidLoad()

    var height = 50;
    for var i = 1; i <= 3 ; i++
     {
         var myTextField: UITextField = UITextField(frame: CGRect(x: 0, y: 0, width: 200.00, height: 140.00));
         myTextField.placeholder = "Enter Email Address \(i)"
         myTextField.center = CGPointMake(160, CGFloat(height))
         height = height + 50;
         self.view.addSubview(myTextField)
     }
    var btn = UIButton(frame: CGRectMake(50, 280, 150, 40));
    btn.setTitleColor(UIColor.blackColor(), forState: UIControlState.Normal);
    btn.setTitle("My Button Text!!", forState:UIControlState.Normal);
    btn.addTarget(self, action: "buttonTapped:", forControlEvents: UIControlEvents.TouchUpInside);
    self.view.addSubview(btn);
    // Do any …

我有个问题。我们如何快速找到第二天的语言。假设今天是2014-09-15。我们如何找出日期：2014-09-16。
