使用 UIViewController 中的表将变量传递给详细视图控制器(不是 UITableViewController ！！) [英] Pass variable to a detail view controller using a table in UIViewController (not UITableViewController!!)

问题描述

我目前有 2 个视图控制器:ViewController 和 DetailViewController.它们都不是表视图控制器，它们都只是视图控制器.但是，我确实有一个关于 ViewController 的表格，它在其他方面很好用.我想在选择一个单元格时将一个变量传递给 DetailViewController.

I currently have 2 view controllers: ViewController and DetailViewController. Neither of them are Table View Controllers, they are both just View Controllers. However, I do have a table on ViewController which is otherwise working great. I want to segue/pass a variable to DetailViewController when a cell is selected.

使用故事板，我设置了一个从单元格到 DetailViewController 的模态转场，标识符为 toDetailView.

Using the storyboard I set up a modal segue from the cell to DetailViewController with the identifier toDetailView.

我尝试使用此方法将我的变量(在本例中称为 play)从 VC 传递到 DVC(通过 http://developer.apple.com/library/ios/#samplecode/SimpleDrillDown/Listings/Classes_RootViewController_m.html#//apple_ref/doc/uid/DTS40007416-Classes_RootViewController_m-DontLinkElementID_10):

I tried to use this method to pass my variable (in this example called play) from VC to DVC (via http://developer.apple.com/library/ios/#samplecode/SimpleDrillDown/Listings/Classes_RootViewController_m.html#//apple_ref/doc/uid/DTS40007416-Classes_RootViewController_m-DontLinkElementID_10):

- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {

    if ([[segue identifier] isEqualToString:@"toDetailView"]) {

        NSIndexPath *selectedRowIndex = [self.tableView indexPathForSelectedRow];
        DetailViewController *detailViewController = [segue destinationViewController];
        detailViewController.play = [dataController objectInListAtIndex:selectedRowIndex.row];
    }
}

但是我收到一个错误:在对象类型ViewController *"上找不到属性tableView".我认为这是因为它不是表视图控制器?我怎样才能解决这个问题?或者我可以使用另一种方法来使用 (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath 来传递和传递变量吗?

However I get an error: Property 'tableView' not found on object type 'ViewController *'. I think this is because it's not a Table View Controller? How can I get around this? Or is there another method I could use to segue and pass the variable using (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath?

推荐答案

在 ViewController 上，创建一个这样的新属性:

On the ViewController, create a new property like that :

@property (nonatomic, assign) IBOutlet UITableView *tableView;

然后合成它.然后，在 Interface Builder 中，您应该能够将插座分配给您正在使用的 tableview.这应该可以解决问题

And synthesize it. Then, in Interface Builder, you should be able to assign the outlet to the tableview you are using. This should do the trick
