在SplitViewController中保持MasterTableView行处于选中状态 [英] Keeping MasterTableView row selected in SplitViewController

问题描述

在我的SplitViewController中，基于DetailViewController中的操作，我基本上使用NSNotificationCenter更新MasterViewController行，如下所示:

In my SplitViewController, based on an action in the DetailViewController, I update the MasterViewController row using NSNotificationCenter essentially like this:

保持MasterViewController和DetailViewController同步

问题是，一旦完成对MasterViewController行的更新，就不再选择该行.当我使用splitViews查看Apple的iPad应用程序时，例如Note应用程序，总是选择一行.我想做同样的事情，所以我的两个表之间的所有内容都保持同步.由于具有tableView的indexPath，因此我可以手动在行上仅setSelected:YES animated:NO，但是在再次设置之前，我仍然看到所选行的蓝色高光闪烁.我不要

The problem is, once an update to the row of the MasterViewController is done, the row is no longer selected. When I look at Apple's iPad apps using splitViews, like the Note application, a row is always selected. I want to do the same thing so everything stays in sync between my two tables. I can manually just setSelected:YES animated:NO on the row since I have the indexPath of the tableView, but I still do see the blue highlight of the selected row flicker off before getting set on again. I don't want that.

MasterViewController:

MasterViewController:

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
    if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPad) {
        Scene *object = [[[DataManager sharedInstance] sceneArray] objectAtIndex:indexPath.row];
        self.detailViewController.detailItem = object;
    }
}

推荐答案

这是关键-在UITableViewController上设置此属性:

This is the key - set this property on the UITableViewController:

self.clearsSelectionOnViewWillAppear = NO;
