iOS錯誤消息：中斷或案例語句未循環或切換

[英]iOS error msg: Break or Case Statement not in loop or switch

問題描述

編程新手。 使用隨機數生成器和每個類別問題的案例陳述，創建具有不同類別的測驗應用程序。 我有2個問題。 一個是.m文件中的一行。 每個類別均以-（IBAction）xyz：（id）sender開頭； 在一行中，我不斷收到錯誤消息“期望的表達式”。 我還注意到帶有這條線的那一側沒有顯示表示按鈕鏈接的圓圈。 我嘗試了重新鏈接按鈕，但收到了同樣的錯誤消息。

（不確定是第一個問題引起第二個問題）第二個問題是.m文件中的同一類別，我不斷收到以下錯誤消息：Break或case語句未循環或切換。我復制並粘貼了代碼以確保縮進和拼寫正確從沒有此錯誤聲明的類別中刪除，但在此部分代碼中我仍然得到這些錯誤消息。 我不知道如何解決。 請幫忙。 我包括了帶有上述錯誤的行。 謝謝

switch(){

case 1: {

}

case 2: {

}

}

嘗試將您的案件放在{..}中，這對我來說是上一次工作。
