UITableView didSelectRowAtIndexPath:不工作

Question

当我选择表格行时,没有任何反应.它没有去ContentController,UILabel当我想链接到ContentController时,我找不到我在ContentController.h上声明的内容resultLabel.

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
    ContentController *detailview = [[ContentController alloc] initWithNibName:@"ContentController" bundle:nil];    
    detailview.detailString = [NSString stringWithFormat:@"%d",indexPath.row];
    [self.navigationController pushViewController:detailview animated:YES];     
    [detailview release];
}

ContentController

- (void)viewDidLoad
{
    [super viewDidLoad];
    // Do any additional setup after loading the view from its nib.
    resultLabel.text = self.detailString;
}

这可能是因为您没有将表视图属性设置为委托和数据源:

tableview.delegate=self;
tableview.datasource=self;

或者在xib中设置它们的属性是另一种选择
