ios - 如何在同一函数中再次调用部分代码？

Question

我想在同一个函数中再次使用代码而不为它做额外的函数。

虽然我的 pinchGesture 是 .ended 现在我想调用这个条件(如代码所示)。

    func isParformPinch(recognizer:UIPinchGestureRecognizer, forTag tag:Int, protectedTag protact:Int){

        if protact == tag{
            return
         }

    //THIS PART CALL AGAIN 

        if isPinching(forView: imageArray[tag],inView: recognizer.view!,  fromTransformation: recognizer.scale) {                                
             imageArray[tag].transform = imageArray[tag].transform.scaledBy(x: recognizer.scale, y: recognizer.scale)                     
         }

      if recognizer.state == .ended{
          // call again above condition

       }
    }

func isParformPinch(recognizer:UIPinchGestureRecognizer, forTag tag:Int, protectedTag protact:Int){

    if protact == tag{
        return
    }

    do {
        //THIS PART CALL AGAIN

        if isPinching(forView: imageArray[tag],inView: recognizer.view!,  fromTransformation: recognizer.scale) {
            imageArray[tag].transform = imageArray[tag].transform.scaledBy(x: recognizer.scale, y: recognizer.scale)
        }

    }while(recognizer.state == .ended);  // if true, call again above condition

}
