Hello:
Below is the document view of MainWindow.xib where I have 2 tabs (Plan One and
Plan Two).
-- Files Owner
-- App Delegate (CPSAppDelegate)
-- Window
-- Tab Bar Controller (rootController : UITabBarController)
-- -- -- Tab Bar
-- -- -- Plan One Navigation Controller (PlanOneNavController :
UINavigationController)
-- -- -- -- -- Region Table View Controller (PlanOneTableViewControler --->
RegionTableView.xib)
-- -- -- -- -- Plan One View Controller (PlanOneViewController --->
PlanOneView.xib)
-- -- -- Plan Two Navigation Controller (PlanTwoNavController :
UINavigationController)
-- -- -- -- -- Region Two Table View Controller (PlanTwoTableViewControler --->
RegionTwoTableView.xib)
-- -- -- -- -- Plan Two View Controller (PlanTwoViewController --->
PlanTwoView.xib)
By default, Plan One tab is loaded with "RegionTableView.xib" under
PlanOneNavController stack which displays list of regions in table view. When
user click on a region, "PlanOneView.xib" is pushed on top of
PlanOneNavController stack.
In PlanOneView.xib file, I have UITextField (Outlest name is: txtCrop) which I
want to set some value from outside using app delegate. I was trying with the
following code to set value to txtCrop outlet but it is not working.
- (void)tableView:(UITableView *)aTableView
didSelectRowAtIndexPath:(NSIndexPath *)newIndexPath
{
selection = [[self.itemArray objectAtIndex:[newIndexPath row]] retain];
// Update the Crop text field with the selected crop
CPSAppDelegate *delegate = [[UIApplication sharedApplication] delegate];
[delegate.planOneViewController.txtCrop setText:selection];
}
I was wondering if there is any expert who can give me some guidance on how to
make the call correctly using app delegate such that when a row is selected
(didSelectRowAtIndexPath method), it automatically update the txtCrop outlet in
PlanOneView.xib file with the selected value (selection variable).
If anybody interested in trying the code, please feel free to download from
http://orcausa.org/cps.zip and do the following:
1. Fire up the project, build and go
2. Click on any region in Plan one tab
3. Click on 'V' button next to the txtCrop outlet (UITextField), the first one
4. Select a crop and click on 'OK' button.
The goal / intention is to populate selected item to the txtCrop outlet
(UITextField) of PlanOneView.xib
Any help/pointer/guidance on how to make the call correctly would be greatly
appreciated.
Thank you so much.
Reza.
