tableview-無法識別的選擇器發送到實例

Question

我剛在我的應用程序中遇到此錯誤。

2010-04-06 03:58:55.505 EasyPay DPS[6530:207] *** -[NTItems tableView]: 
 unrecognized selector sent to instance 0x397af90

2010-04-06 03:58:55.515 EasyPay DPS[6530:207] *** 
 Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 
 '*** -[NTItems tableView]: unrecognized selector sent to instance 0x397af90'

該錯誤非常無用-我從代碼的哪里開始？

這是堆棧：

Answer 1

您的問題出在第38行的viewDidLoad 。

仔細檢查方法名稱，接收者名稱等。

Answer 2

嘗試在調用之前將tableView屬性或方法添加到NTItems，或從UITableViewController派生，以便為您定義該方法。
