swift:Storyboardから@IBOutletを作った時にproperty not initialized at super.init callのエラーが出た場合の対処

Posted at

StoryBoardから@IBOutletのソースを生成します

こんなソースが生成されます

SampleViewController
    @IBOutlet strong var btn: UIButton

コンパイル時エラーが発生


<unknown>:0: error: property 'self.btn' not initialized at super.init call

strongを外しましょう

SampleViewController
    @IBOutlet var btn_info: UIButton
