我一直在爲一個奇怪的問題掙扎了兩天。我經歷了所有關於SO的相關問題,但都沒有解決這個問題。我正在研究Xcode5。我正在使用ARC和CoreData。[CFString發佈]:發送到釋放實例的消息
在iOS7(仿真器):
`[CFString release]: message sent to deallocated instance`

殭屍儀器指向哪裏設定該單元的文本標籤的第二行:
cell.txtLabel.text = _reservationModule.newReservationText;
cell.subtitleTxtLabel.text = _reservationModule.newReservationSubtitle;
_reservationModule
是表徵字符串特性的核心數據實體。它在視圖控制器定義爲@property (nonatomic, strong) ReservationModule *reservationModule;
殭屍歷史:

他們從來沒有在Xcode中4.6.X發生雖然。 任何幫助,高度讚賞!
謝謝!
這有助於我ARC宣佈其名稱 開始新的屬性:http://stackoverflow.com/a/10596942/3411787 –
