如何访问Apple关注应用

Question

一个WKInterfaceLabel的Text属性我想键入InterfaceController if语句基本上去喜欢 -

if label.text == "Hello" { 
//execute some code 
} 

但WKInterfaceLabel似乎只是有setText()财产。那么如何访问WKInterfaceLabel的文本属性？提前致谢！

简答：你不能。

较长的答案，将字符串存储在一个单独的变量中，并将其用于if语句。

class InterfaceController: WKInterfaceController { 

    @IBOutlet var myLabel: WKInterfaceLabel! 
    var myString : String = "" 

    override func awakeWithContext(context: AnyObject?) { 
     super.awakeWithContext(context) 

     myString = "hello" 
     myLabel.setText(myString) 

     if myString == "hello" { 

      //so awesome stuff here 

     } 
     // Configure interface objects here. 
    } 

    override func willActivate() { 
     // This method is called when watch view controller is about to be visible to user 
     super.willActivate() 
    } 

    override func didDeactivate() { 
     // This method is called when watch view controller is no longer visible 
     super.didDeactivate() 
    } 

}
