iphone - didSelectRowAtIndexPath 抛出异常

Question

这可能是一些简单的错误，我似乎无法在我的代码中找到它。

每当我在我的表格 View 中点击一个单元格时，我都会得到一个异常

这是我的界面:

@interface MenuViewController : UIViewController <UITableViewDataSource, UITableViewDelegate>

@end

我不使用 XIB 文件，所以这是我的 loadView

- (void)loadView
{
    UIView *myview = [[UIView alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
    self.title = @"Menu";
    UITableView *tableViewMenuItems = [[UITableView alloc] initWithFrame:CGRectMake(10, 10, 300, 150) style:UITableViewStyleGrouped];
    tableViewMenuItems.backgroundColor = [UIColor clearColor];
    tableViewMenuItems.delegate = self;
    tableViewMenuItems.dataSource = self;
    tableViewMenuItems.scrollEnabled = NO;
    [myview addSubview:tableViewMenuItems];
    [tableViewMenuItems release];
    self.view = myview;
    [myview release];
}

这是选择行的委托(delegate)方法

-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
    SendMessageViewController *sendMessageViewController = [[SendMessageViewController alloc] init];
    [self.navigationController pushViewController:sendMessageViewController animated:YES];
    [sendMessageViewController release];
}

还有我的BT

我做错了什么？

Answer 1

看看这一行

-[NSObject(NSObject) doesNotRecognizeSelector:] ()

它清楚地表明，当您单击表格 View 单元格时，您正在调用代码中某处不存在的方法。尝试在 SendMessageViewController

的 viewDidLoad 和 viewWill/DidAppear 方法中搜索警告
