ios - 在 appdelegate 中以编程方式选择 tableview 单元格不起作用

Question

我正在使用自定义 URL 方案打开特定 View 并选择表格 View 的特定单元格。但是，单元格选择代码不起作用。翻了stackoverflow还是没找到解决办法

- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation {

if ([url.host isEqual: @"help"]){
    UITabBarController *tabController = (UITabBarController*)self.window.rootViewController;
    tabController.selectedIndex = 4;
    MoreController* more = [[UIStoryboard storyboardWithName:@"Main" bundle:nil] instantiateViewControllerWithIdentifier:@"more"];
    [more.tableView selectRowAtIndexPath:[NSIndexPath indexPathForRow:2 inSection:1] animated:true scrollPosition:UITableViewScrollPositionNone];
}

每当我使用 url myapp://help 打开应用程序时，它只会停留在选定的索引处，而不会选择单元格。

如果你的 MoreController 已经加载到 UITabBarController 中，你需要写这个

- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation {

    if ([url.host isEqual: @"help"]){
        UITabBarController *tabController = (UITabBarController*)self.window.rootViewController;
        tabController.selectedIndex = 4;
        MoreController* more =  (MoreController *)[[tabController viewControllers] objectAtIndex:4];
        [more.tableView selectRowAtIndexPath:[NSIndexPath indexPathForRow:2 inSection:1] animated:true scrollPosition:UITableViewScrollPositionNone];
    }
}
