UIViewTableCell didSelectRowAtIndexPath is calling but not pushing a view controller

Question

Hi guys, so im having a UIViewController view with a UITableView. So the UIViewController class name is SelectionScreen. The UITableView class name is SelectionScreenTable.

Picture: http://img717.imageshack.us/i/screenshot20100609atpm0.png/

I have declared a UITableView *selectionTable in SelectionScreen class and connected it to the xib file of the SelectionScreen

what the problem is , is that when i click a row in the table,it stays selected as highlighted blue, it calls the didSelectRowAtIndexPath (checked with NSLog) but not pushing a new view which is called(GraphView).

This is the code which i use to call the new controller WHICH WORKS with a normal button

GraphView *aSelectionScreenViewController = [[GraphView alloc]
         initWithNibName:@"GraphView"
         bundle:nil];

[self presentModalViewController:aSelectionScreenViewController animated: YES]; [aSelectionScreenViewController release];

I searched around and found that I need to set a delegate for the table in the UITableView class itself on the viewload

tableview.delegate = self;

or

self.tableview.delegate = self;

But it was not working. the controller was still not being pushed, and yes i have checked the controller is not nil as i tried it with a simple button.

So i was thinking whether i should set the delegate of the UITableView at the UIViewController instead, so i tried this code

selectionTable.delegate = selectionTable.self;

but obviously it did not work =\, it messed up the whole UITableView and caused all the cells to be its predefined settings.

So does anybody have any idea on how i can get it to work.

Answer 1

It's a bit hard to get the full picture here, but I can try some hints.

The outlets seem to be correctly connected from the screenshot, although Selection Screen Table could probably be called Selection Screen Table Controller and the class name should be SelectionScreenTableController for less confusion.

I think the problem could be that the method presentModalViewController: must be called on an active view controller to work.

From what I can tell you have three view controllers, a SelectionScreenTableController, a GraphViewController, and then there must also be some kind of main controller, probably SelectionScreenController.

The SelectionScreenController is the active view controller, so that must be the one to have sent the presentModalViewController: message.

There are several ways you could solve this. The quick fix would be to make an outlet in SelectionScreenTableController called selectionScreenController and link it to File's Owner in the nib file (assuming your SelectionScreen class is in fact a view controller), then call:

[selectionScreenController
    presentModalViewController:aSelectionScreenViewController
    animated: YES];

instead in your current listing of didSelectRowAtIndexPath:

Hey guys, i solved it, in the screenshot

The SelectionScreenTable controller in the XIB of SelectionScreen, the view outlet was not connected to the XIB in the SelectionScreen XIB, so i guess it wasn't properly configured.

Hmm actually i have another problem now, the view is not being presented properly In this first 'drawing' i have a view that has a UItableView http://img814.imageshack.us/i/sshot1u.png/

But once i click a UITableViewcell, the graphview is being presented in this way :\ (screenshot below at comment)

im using this code [self presentModalViewController:viewController animated:YES]

instead of the normal standard code for didRowSelectAtIndexpath which is not working....

[[self navigationController] pushViewController:viewController animated:Yes];

any idea guys?

Hey guys its me again.

i solved it instead of using presentModalViewController.

i used an animation to bring in the view instead More info in the link below http://www.iphonedevsdk.com/forum/iphone-sdk-development/13427-uiview-slide-transition.html
