addTarget:action:forControlEvents した時に引数も渡す

Last updated at Posted at 2015-12-25

UIButton などを押した時のアクション設定で addTarget:action:forControlEvents した時に一緒に引数を渡したい。

引数は選ぶことができないが、SenderとEventを渡すことができる。

// 引数なしの場合
button.addTarget(button, action: "touchedMe", forControlEvents: .TouchUpInside)

// Senderを渡す場合 : をセレクタの最後につける。イベントを発生させたオブジェクトになるので、この場合 button が送られる。
button.addTarget(button, action: "touchedMe:", forControlEvents: .TouchUpInside)

// Eventも渡す場合 :event: をつける
button.addTarget(button, action: "touchedMe:event:", forControlEvents: .TouchUpInside)

Passing parameters to addTarget:action:forControlEvents
