Question

对不起，但如果我有一些来自plist文件的按钮...... 如何重新创建所有按钮？示例我尝试了这种方式：

 func loadSavedButtons() {
 // I extract the number from the plist file 
 var number: AnyObject? = data.valueForKey("NumberOfButton")
 var someNumb: Int = ("\(number!)").toInt()!
 if (someNumb != 0) {
 self.countButton = someNumb
 for (var i=0; i < someNumb; i++) {

在这一点上，我应该做

 var newButton6: () = CreateButtonWithIndex(i)
 self.view.addSubview(newButton6)
 }}}

和

 @IBAction func CreateButtonWithIndex(sender: AnyObject){
 let button = UIButton.buttonWithType(UIButtonType.System) as UIButton
 ecc…
 self.view.addSubview(button)

但是不要......我没有全部保存按钮请帮助我!!!

在你的功能中更改以下

let button = UIButton.buttonWithType(UIButtonType.System) as UIButton

到

var button = UIButton.buttonWithType(UIButtonType.System) as UIButton

之后

self.view.addSubview(button)

添加以下内容：

button = UIButton.new()

如何在viewDidLoad（Swift）上创建多个UIButton
