.M文件，這是我對自我簽名證書進行身份驗證並使用nsurl連接檢索它並將其解析爲nsxmlparser之前把它們放到tableview中。但我可以收到數據，但可以檢索具有名稱「嚴重性」的特定元素。請幫忙。！！我需要將Severity中的項加載到數組中並插入到表視圖中。IOS如何在調用成功後在xml中檢索其中一個元素，並將其放入一個數組中以在tableview上顯示

你能回答我的代碼基礎，但不是我看看你的代碼，並希望我能理解你的代碼代碼。因爲我也不明白。這就是爲什麼我在這裏問。非常感謝！ – zac
我編輯我的方法對於你的Xml解析器，也不要忘了初始化視圖Feed feed = [[NSMutableArray alloc] init]; – vp2698
你在哪裏聲明瞭元素屬性？ – zac
