Modal display is not working correctly

[Fastrak]

After killing much time trying to figure out something with modal displays - I opened up Apple's example NavBar

If you;

1 - run this app
2- select "View 5" from the list
3- then click OK on the modal window that appears
4 - repeat steps 2-3 several times

eventually what happens is that only view 1 will be presented when you click View 5.

I am posting this to try to prevent someone else from wasting a bunch of time (as I did) trying to track down a peculiar behavior in their program.

I have noticed the issue with the demo too. But it just worked once for me and i was not able to get it work again. But, the code works, just copy the code into your project and see if it works for you too.

Uh..If it worked just once for you then did not work again then IT DOESNT WORK!!!! That was the whole point of my post

Yes, you are right. But, your topic subject was Modal Display does not work which means modal views don't work at all. It just doesn't work in the demo program provided by the apple but it should definitely work in your project. Because, I am using Modal views in my application and it works perfectly fine.

Are you using an alertSheet or calling presentModalViewController?

Alertsheets are working fine for me - the specific trouble is with presentModalViewController.

[javid.alimohideen]

I am using the presentModalViewController.

[Fastrak]

What are you calling when you are done with the view?

The apple example calls
[self.navigationController dismissModalViewControllerAnimated:YES];

Did you use setModalViewController before you asked for the modal view to be shown?

[javid.alimohideen]

I show my modal view from my main view controller using code below

[self.navigationController presentModalViewController: myModalViewController animated:YES];

and in my ModalViewController class i dismiss it with a button action
using code below

-(void) dismiss:(id)sender
{
   [self dismissModalViewControllerAnimated:YES];
}

Nope still getting the same result.

If the modal view is called from an indexed caller like:
- (void)segmentActionid)sender
{
NSLog(@"segmentAction: selected segment = %d", [sender selectedSegmentIndex]);
switch ([sender selectedSegmentIndex]) {
case 0:
[self flipToageNum-1];
break;
case 1:
// show modal form!
[self.navigationController presentModalViewController: modalList animated:YES];
break;
case 2:
[self flipToageNum+1];
break;
default:
break;

after the modal view is called and dismissed, a click on any segment always returns segmentindex 0
Display from console:
4/21/08 7:00:56 PM Transitions[3249] segmentAction: selected segment = 1
4/21/08 7:00:57 PM Transitions[3249] segmentAction: selected segment = -1
4/21/08 7:01:05 PM Transitions[3249] segmentAction: selected segment = 0
4/21/08 7:01:05 PM Transitions[3249] segmentAction: selected segment = -1
4/21/08 7:01:13 PM Transitions[3249] segmentAction: selected segment = 0
4/21/08 7:01:13 PM Transitions[3249] segmentAction: selected segment = -1
I guess a -1 is issued when my button pops back up BUT I clicked the middle button 3 times and you can see that the wrong index is reported after the modal view was displayed

if I comment out the call to display the modalview, the console reports:
4/21/08 7:04:21 PM Transitions[3273] segmentAction: selected segment = 1
4/21/08 7:04:22 PM Transitions[3273] segmentAction: selected segment = -1
4/21/08 7:04:24 PM Transitions[3273] segmentAction: selected segment = 1
4/21/08 7:04:24 PM Transitions[3273] segmentAction: selected segment = -1
4/21/08 7:04:25 PM Transitions[3273] segmentAction: selected segment = 1
4/21/08 7:04:25 PM Transitions[3273] segmentAction: selected segment = -1

If you use a button to call it (instead of something that takes an index) everything works correctly

I've had the same problem with segmented controls.
It should be noted that modal displays tend to reshuffle the view layers a bit so you may have to restore order your segmented control or other views.
