iphone - 'NSInvalidArgumentException' : unrecognized selector sent to instance 0x8d25aa0'

Question

我正在为 IOS 6 开发 Tableview(Master/Detail)模板，我收到以下错误:'NSInvalidArgumentException'，原因:'-[DetailViewController saveAcctData:]: unrecognized selector sent to instance 0x8d25aa0'

这是我的代码:这是什么意思？任何帮助，将不胜感激。谢谢。

- (IBAction)saveAcctData {
    NSMutableArray *array = [[NSMutableArray alloc] init];

    [array addObject:AcctName.text];
    [array addObject:AcctNum.text];
    [array addObject:DayDue.text];
    [array addObject:paymnt.text];
    [array addObject:remBalance.text];

    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask,YES);

    NSString *documentPath = [paths objectAtIndex:0];

    NSString *plistPath = [documentPath stringByAppendingPathComponent:@"Accounts.plist"];

    [array writeToFile:plistPath atomically: true];
}

您必须从某处以 saveAcctData:(带冒号)调用该方法，但您的方法实现没有冒号。
