修改

这是我当前使用编程按钮的代码。

    override func viewDidLoad() {
    super.viewDidLoad()
    self.playVideo()
    var filter = UIView()
    filter.frame = self.view.frame
    filter.backgroundColor = UIColor.orangeColor()
    filter.alpha = 0.15
    self.view.addSubview(filter)
    // Do any additional setup after loading the view, typically from a nib.

    //Add Images
    var logoImage : UIImageView
    logoImage = UIImageView(frame:CGRectMake(136, 50, 102, 104));
    logoImage.image = UIImage(named:"patchicon.png")
    self.view.addSubview(logoImage)
    var textLogo : UIImageView
    textLogo = UIImageView(frame:CGRectMake(51, 0, 273, 371));
    textLogo.image = UIImage(named:"logopatch.png")
    self.view.addSubview(textLogo)

    //Add Buttons
    let buttonLogin = UIButton.buttonWithType(.Custom) as! UIButton
    buttonLogin.frame = CGRectMake(16, 519, 343, 60)
    buttonLogin.layer.cornerRadius = 0.2 * buttonLogin.bounds.size.width
    buttonLogin.addTarget(self, action: "buttonTouched", forControlEvents: UIControlEvents.TouchUpInside)
    buttonLogin.setImage(UIImage(named:"loginButton.png"), forState: .Normal)
    view.addSubview(buttonLogin)

    let buttonRegister = UIButton.buttonWithType(.Custom) as! UIButton
    buttonRegister.frame = CGRectMake(16, 587, 343, 60)
    buttonRegister.layer.cornerRadius = 0.2 * buttonRegister.bounds.size.width
    buttonRegister.addTarget(self, action: "buttonTouched2", forControlEvents: UIControlEvents.TouchUpInside)
    buttonRegister.setImage(UIImage(named:"registerButton.png"), forState: .Normal)
    view.addSubview(buttonRegister)


}
func buttonTouched()
{
    performSegueWithIdentifier("loginTouched", sender: nil)
}
func buttonTouched2()
{
    performSegueWithIdentifier("registerTouched", sender: nil)
}

这就是我的故事板的样子： http://i.stack.imgur.com/MlEhI.png

如何进一步编程这些按钮以切换到新的视图控制器？例如，我想点击注册按钮，我希望当前的MainViewController切换到一个新的，它将具有供用户注册的信息，等等...... 谢谢！

Answer 1

首先，您需要向按钮添加目标：

buttonLogin.addTarget(self, action: "buttonTouched", forControlEvents: UIControlEvents.TouchUpInside)

然后，添加此功能：

func buttonTouched()
{
   println("touched")
}

要切换到新的视图控制器take a look at this

Answer 2

将目标添加到按钮..

buttonLogin.addTarget(self, action: "btnpressed:", forControlEvents: .TouchUpInside)

Vtwot是我的第二个viewController，它的Storyboard Id是ViewTwoId ..

使UIButton像这样行动..

func btnpressed(sender: UIButton!) 
{
    let jj = self.storyboard!.instantiateViewControllerWithIdentifier("ViewTwoId") as! Vtwot
    self.navigationController!.pushViewController(jj, animated: true)
}

我希望它有所帮助......

好吧，切换到＆＃34; new＆＃34;在视图控制器中，您需要首先在故事板中创建该视图控制器。之后，您是否看到将主视图控制器链接到其他两个的那条线？单击该行并转到＆＃34;属性检查器＆＃34;。在标识符空白处填写您想要的任何内容，然后在您以编程方式创建的按钮中，您需要设置 this ：

performSegueWithIdentifier("whateverYouWant", sender: self)

哦，不要忘记这一步：选择主视图控制器，转到编辑器＆gt;嵌入＆gt;导航控制器。如果您不这样做，您的应用程序将崩溃。

希望有所帮助！

编辑：试试这个：

在viewDidLoad方法之外写一些这样的函数：

func segueToNextVC(sender: UIButton!) {
println("Button pressed, let's see what happens!")
performSegueWithIdentifier("whateverYouWant", sender: self)
}

然后，在viewDidLoad中的按钮中，执行以下操作：

buttonLogin.addTarget(self, action: "segueToNextVC:", forControlEvents: UIControlEvents.TouchUpInside)

注意：不要忘记segueToNextVC中的：，这很重要！
