Question

我是ios编程的新手，我在storyboard中的导航控制器内有viewcontroller，在那个viewcontroller我有tableview项目，所以onclick项目我必须提供一些viewcontroller这是xib viewcontroller，我尝试了一些代码我是得到例外。

    code:

         -(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{
                ThirdController *detailViewController = [[ThirdController alloc] initWithNibName:@"ThirdController" bundle:nil];

                [self.navigationController pushViewController:detailViewController animated:YES];

        }

exception:
SampleNaviationController[2499:84098] *** Terminating app due to uncaught exception 'NSUnknownKeyException', reason: '[<ThirdController 0x7c02d9d0> setValue:forUndefinedKey:]: this class is not key value coding-compliant for the key sendResponse.'

您的ThirdViewController中没有String q = "Select Column1, Column2 from TableName";属性;因此崩溃。

我猜这是怎么回事。在xib中配置按钮后，您将sendResponse设为 outlet 。您可能希望它是动作。

如何从storyboard viewcontroller调用xib viewcontroller
