Another UITableViewController problem

[lex]

Hay at all readers out there,
At first let me please say that im not to stupid or to lazy to use google or search function in here.

I have a big problem.

I've build in my app delegate a UINavigation controller with my MainView (UIViewController) as a RootController.

mainView = [[[MainView alloc] initWithNibName:nil bundle:nil] autorelease];
	navigationController = [[UINavigationController alloc] initWithRootViewController:mainView];
	//window = [[UIWindow alloc] initWithFrame:[UIScreen mainScreen].bounds];
	[window addSubview:[navigationController view]];
    // Override point for customization after application launch
    [window makeKeyAndVisible];

Tis works without problems, I push and pop some UIViews there for Navigation purposes without dislaying the Navbar, this also works.

I push on the stack a UITableviewcontroller with an object reference to an object which my appdelegate constructs. my tableview is also populated with the correct dataparts. and i can edit and delete my entries and also I have a working detailview.

All works, EXCEPT TWO THINGS,

if i change in the Edit view (clic in my tableview on an entry --> Detail view with all data ->edit -> datapart -> Editview) and save this and get poped back to detail view, NOTHING changed in the view, no deselect of the cell and no refresh, if I enter again the edit view the data are correct.
if i pop back to the table view the data also are not refreshed, and if i push again the detail view all data correct. if i scroll up and downwards, the cells wich dissapear are refreshed. the same with the Add Item menu.

I inserted the tableView reloadData and other tries but nothing worked for me.

I generate all programmatically because i dislike the IB.

I think i have troubles with the datadelegate and the tableviewdelegate.

I found nothing about that how i had to connect these correct to my files.
The example i looked in was partly build with IB and I can't figure out how this works with the delegate things.

I hope my question is not to stupid.
and thanks that tis forum exist it helped me till now very very much.

Sorry, I don't have the answer to your question, but I had to respond to the line you said above.

You should read this and then start learning IB.

I inserted the reloadData once in viewwillappear, here some code

- (void)viewDidLoad {
	NSLog(@"viewdidload");
    self.navigationItem.rightBarButtonItem = self.editButtonItem;
	[self.tableView reloadData];
}

- (void)viewWillAppear:(BOOL)animated {
	NSLog(@"viewwillappear");
    
	//no work
	[self.tableView deselectRowAtIndexPath:selectedIndexPath animated:NO];

	// also no work
	[[self tableView] reloadData];
	//the same
	[self.tableView reloadData];
}

- (void)setEditing:(BOOL)editing animated:(BOOL)animated {
	NSLog(@"setediting");
    [super setEditing:editing animated:animated];
    [self.navigationItem setHidesBackButton:editing animated:animated];
    //also no work
    [tableView reloadData];
}

All works except the refresh and the deselecting.

in attachement is the example i wanted to rebuild without the IB because then i know what the programm does, i thought, IB is for me too fixed. its like if you somebody from the c world say he should use visual basic. im not angry or something i only try my way.

can you tell me how i had to set my delegates ???


following the header files from my own build.
compilation without error.

My DetailView

#import <UIKit/UIKit.h>


@class Ship, EditingViewController;

@interface DetailView : UITableViewController <UITableViewDelegate, UITableViewDataSource> {
    Ship *ship;
    IBOutlet UITableView *tableView;
    NSDateFormatter *dateFormatter;
    NSIndexPath *selectedIndexPath;
}

@property (nonatomic, retain) NSDateFormatter *dateFormatter;
@property (nonatomic, retain) UITableView *tableView;
@property (nonatomic, retain) NSIndexPath *selectedIndexPath;
// Expose the book property to other objects (the MasterViewController).
@property (nonatomic, retain) Ship *ship;

@end

My EditingView

@interface EditingViewController : UIViewController {
    NSString *textValue;
    id editedObject;
    NSString *editedFieldKey;
    IBOutlet UITextField *textField;
    BOOL dateEditing;
    NSDate *dateValue;
    IBOutlet UIDatePicker *datePicker;
    NSDateFormatter *dateFormatter;
}

@property (nonatomic, retain) id editedObject;
@property (nonatomic, retain) NSString *textValue;
@property (nonatomic, retain) NSDate *dateValue;
@property (nonatomic, retain) NSString *editedFieldKey;
@property (nonatomic, assign) BOOL dateEditing;
@property (nonatomic, readonly) UITextField *textField;
@property (nonatomic, retain) NSDateFormatter *dateFormatter;

- (IBAction)cancel:(id)sender;
- (IBAction)save:(id)sender;
- (IBAction)dateChanged:(id)sender;

@end

my AddView

#import <UIKit/UIKit.h>


#import "DetailView.h"

@interface AddViewController : DetailView

- (IBAction)cancel:(id)sender;
- (IBAction)save:(id)sender;

@end

and my ShipController

#import <UIKit/UIKit.h>

@class DetailView, AddViewController, EditingViewController, Ship;

@interface ShipViewController : UITableViewController <UITableViewDelegate,UITableViewDataSource>{
	
	IBOutlet UITableView *tableView;
    UINavigationController *addNavigationController;
    DetailView *detailView;
    AddViewController *addViewController;

}

@property (nonatomic, retain) UITableView *tableView;
@property (nonatomic, retain) UINavigationController *addNavigationController;
@property (nonatomic, retain) DetailView *detailView;
@property (nonatomic, retain) AddViewController *addViewController;

+ (EditingViewController *)editingViewController;

- (IBAction)addShip:(id)sender;
- (IBAction)backIt;

@end

This is how i push the shipcontroller on the stack.

....

- (ShipViewController *)shipViewController {
	NSLog(@"ShipView Invoked");
	
    // Instantiate the detail view controller if necessary.
    if (shipViewController == nil) {
        shipViewController = [[ShipViewController alloc] initWithStyle:UITableViewStyleGrouped];
    }else{
		
		shipViewController = nil;
		shipViewController = [[ShipViewController alloc] initWithStyle:UITableViewStyleGrouped];
		NSLog(@"pclistview no New Detail anzeige Invoked");
		
		
	}
    return shipViewController;
}


//-----------


-(IBAction)shipview{
	
	ShipViewController *swc = self.shipViewController;
	[self.navigationController pushViewController:swc animated:YES];
	[swc release];
	
	
}

and this is the button which exists in the init

UIButton *button2 = [UIButton buttonWithType:UIButtonTypeRoundedRect];
button2.frame = CGRectMake(100, 170, 120, 30);
[button2 setTitle:@"Schiffe" forState:UIControlStateNormal];
[button2 addTarget:self action:@selector(shipview) 
		  forControlEvents:UIControlEventTouchUpInside];
		[self.view addSubview:button2];

please have a look at it

Have you checked to see if self.tableView exists during the viewWillAppear call? I bet it doesn't. NSLog it and see.

#import <UIKit/UIKit.h>


@class Ship, EditingViewController;

@interface DetailView : UITableViewController <UITableViewDelegate, UITableViewDataSource> {
    Ship *ship;
    IBOutlet UITableView *tableView;
    NSDateFormatter *dateFormatter;
    NSIndexPath *selectedIndexPath;
}

@property (nonatomic, retain) NSDateFormatter *dateFormatter;
@property (nonatomic, retain) UITableView *tableView;
@property (nonatomic, retain) NSIndexPath *selectedIndexPath;
// Expose the book property to other objects (the MasterViewController).
@property (nonatomic, retain) Ship *ship;

@end

Items in red are not necessary for a UITableViewController, and possibly are contributing to your problem if not done correctly. See the table view link in my signature for more information.

#import <UIKit/UIKit.h>

@class DetailView, AddViewController, EditingViewController, Ship;

@interface ShipViewController : UITableViewController <UITableViewDelegate,UITableViewDataSource>{
	
	IBOutlet UITableView *tableView;
    UINavigationController *addNavigationController;
    DetailView *detailView;
    AddViewController *addViewController;

}

@property (nonatomic, retain) UITableView *tableView;
@property (nonatomic, retain) UINavigationController *addNavigationController;
@property (nonatomic, retain) DetailView *detailView;
@property (nonatomic, retain) AddViewController *addViewController;

+ (EditingViewController *)editingViewController;

- (IBAction)addShip:(id)sender;
- (IBAction)backIt;

@end

Why do you have a navigation controller inside of a view controller? I'm going to guess this is your problem.

@briterideas
Ok that helped a bit, i didnt know that it works without, but now there on the addView ( this loads the detail view ) there on each cell the erase signs on the left. ive added you to aim, if you are in the mood for reading my silly postings via aim i would be pleased. my is lexarion (aT) mac.com


Thanks for helping me till now
