Question

我正在使用委托来获取用户在表格视图中选择的选项，但我不断收到如下错误：

2012-05-12 23：26：06.704 test [4629：fb03] - [AddContentViewController catPickViewController：didSelectGame：]：无法识别的选择器发送到实例0x6d79ed0

我在表格视图中记录了该选项，但无法在第一个视图中记录该选项。

这就是我在表格视图中的内容

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
    [tableView deselectRowAtIndexPath:indexPath animated:YES];

    if (selectedIndex != NSNotFound)
    {
        UITableViewCell *cell = [tableView cellForRowAtIndexPath:[NSIndexPath indexPathForRow:selectedIndex inSection:0]];
        cell.accessoryType = UITableViewCellAccessoryNone;
    }

    selectedIndex = indexPath.row;
    UITableViewCell *cell = [tableView cellForRowAtIndexPath:indexPath];
    cell.accessoryType = UITableViewCellAccessoryCheckmark;

    NSString *theGame = [games objectAtIndex:indexPath.row];
    NSLog(@"%@",theGame);
    [self.delegate catPickViewController:self didSelectGame:theGame];

}

这就是我对select方法的看法：

- (void)CatPickViewController:(CatPickViewController *)controller didSelectGame:(NSString *)theGame
{
    NSLog(@"%@",theGame);
    category = theGame;
    self.catDetails.text = category;

    [self.navigationController popViewControllerAnimated:YES];
}

我知道问题出在[self.delegate catPickViewController：self didSelectGame：theGame];

但我该怎么办呢？

我忘了提到我有catPickViewController.h喜欢

@class CatPickViewController;

@protocol CatPickViewControllerDelegate <NSObject>
- (void)catPickViewController:(CatPickViewController *)controller didSelectGame:(NSString *)game;
@end

@interface CatPickViewController : UITableViewController

@property (nonatomic, weak) id <CatPickViewControllerDelegate> delegate;
@property (nonatomic, strong) NSString *game;

@end

所以你们提到的catPickViewController来自这里

Answer 1

您正在呼叫catPickViewController，但方法名称拼写为CatPickViewController。您应该将其更改为catPickViewController。
