如何打开表格行上的视图控制器点击xamarin ios而不使用segue概念?????

Answer 1

您可以使用present(viewController, animated: true) {}此方法来展示视图控制器，如果您有导航控制器，则可以使用navigationController?.pushViewController(viewController, animated: true)

Answer 2

在您的UITableViewSource中，将方法“RowSelected”覆盖为Follows：

public override void RowSelected (UITableView tableView, NSIndexPath indexPath)
{
    //Instantialte the Storyboard Object
    UIStoryboard storyboard = UIStoryboard.FromName ("YourStoryboardName", null);

    //Instantiate the ViewController you want to navigate to.
    //Make sure you have set the Storyboard ID for this ViewController in your storyboard file.
    //Put this Storyboard ID in place of the TargetViewControllerName in below line. 
    UIViewController vcInstance = (UIViewController)storyboard.InstantiateViewController ("TargetViewControllerName");


    //Get the Instance of the TopViewController (CurrentViewController) or the NavigationViewController to push the TargetViewController onto the stack. 
    //NavigationController is an Instance of the NavigationViewController
    NavigationController.PushViewController(vcInstance, true);
}

或者

使用事件机制，在ViewController中为MyTableSource对象注册此事件，其中添加了TableView。

public class MyTableSource : UITableViewSource
{
    public event EventHandler<RowSelectedEventArgs> OnRowSelected;

    public override void RowSelected (UITableView tableView, NSIndexPath indexPath)
    {
        if (OnRowSelected != null) {
            OnRowSelected (this, new RowSelectedEventArgs (tableView, indexPath));
    }
}


public class MyViewController : UIViewController
{
    MyTableSourceObject.OnRowSelected += (s, ev) => {
        //Your Navigation Logic Goes Here.
    }
}
