【iOS筆記】輸入後，隱藏Keyboard

【iOS筆記】輸入後，隱藏Keyboard

Remarks

以鍵盤輸入時，鍵盤會顯示在最上層，而輸入後，鍵盤應隱藏，而將控制權交給其他控制項。

UI Design

 在 TextField 新增 Action x1 : hideKeyboard, 而由事件 Event: Did End On Exit 來觸發此 Action。

Run Result

輸入後，按鍵盤 Return 鍵，此鍵盤會隱藏。

Review

在MainStoryboard.storyboard圖示有個箭頭，顯示此View的First Responder，而當開始輸入時，鍵盤顯示在上層，而成為 First Responder，因此輸入完，應該以Resign First Responder 方式，將此鍵盤隱藏在後。
