First here is the code showing the uiviewcontroller which contain the uitableview:
//View Controller with navigation bar
InAppPurchaseViewController *purchaseViewController = [[InAppPurchaseViewController alloc] init];
purchaseViewController.title = #"Liste de packs";
purchaseViewController.navigationItem.rightBarButtonItem = [[[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemDone target:self action:#selector(dismissViewController:)] autorelease];
//Creation de la navigation bar et release du viewcontroller
UINavigationController *navController = [[[UINavigationController alloc] initWithRootViewController:purchaseViewController] autorelease];
[purchaseViewController release];
container = [[UIViewController alloc] init];
[container setView:[[CCDirector sharedDirector] openGLView]];
[container setModalTransitionStyle: UIModalTransitionStyleCoverVertical];
[container presentModalViewController: navController animated: YES];
here is my uitableviewcell:
InAppPurchaseCell.h
#interface InAppPurchaseCell : UITableViewCell
#property (strong, nonatomic) IBOutlet UIImageView *ImageThumbnail;
#property (strong, nonatomic) IBOutlet UIButton *BuyButton;
#property (strong, nonatomic) IBOutlet UILabel *TitleLabel;
#property (strong, nonatomic) IBOutlet UILabel *PriceLabel;
#end
InAppPurchaseCell.m
#implementation InAppPurchaseCell
#synthesize PriceLabel;
#synthesize TitleLabel;
#synthesize BuyButton;
#synthesize ImageThumbnail;
-(id)initWithFrame:(CGRect)frame
{
self = [super initWithFrame:frame];
if (self)
{
}
return self;
}
- (void)setSelected:(BOOL)selected animated:(BOOL)animated
{
[super setSelected:selected animated:animated];
}
#end
InAppPurchaseCell.xib
All the iboutlet are linked correctly
And :
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
NSString *cellIdentifierCasual = #"ShopCell";
InAppPurchaseCell *cell = (InAppPurchaseCell*)[tableView dequeueReusableCellWithIdentifier:cellIdentifierCasual];
if (cell == nil)
{
cell = (InAppPurchaseCell*)[[[NSBundle mainBundle] loadNibNamed:#"InAppPurchaseCell" owner:nil options:nil]lastObject];
cell.selectionStyle = UITableViewCellSelectionStyleGray;
}
else
{
cell.selectionStyle = UITableViewCellSelectionStyleGray;
}
Packages *packages = [PackagesParser loadData];
Package *package = [packages.Packages objectAtIndex:indexPath.row];
cell.ImageThumbnail.image = [UIImage imageNamed:#"Icon-Small.png"];
cell.PriceLabel.text = #"0,75$";
cell.TitleLabel.text = package.Name;
return cell;
}
What's hapenning when the table pop up :
2012-07-13 13:56:55.378 Testing[1276:1c103] *** Terminating app due to uncaught
exception 'NSUnknownKeyException', reason: '[<NSObject 0xa10da00>

At this line :
cell = (InAppPurchaseCell*)[[[NSBundle mainBundle] loadNibNamed:#"InAppPurchaseCell" owner:nil options:nil]lastObject];
Does someone has an idea ?
this may help you
InAppPurchaseCell *cell=[tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell==nil) {
cell=[[InAppPurchaseCell alloc]initWithFrame:CGRectMake(0, 0, 200, 100)
reuseIdentifier:#"ShopCell"];

Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: '-[UITableViewController loadView] loaded the "MySubscriptionsViewController" nib but didn't get a UITableView.' This error Ocurce becouse some bellow issue.
I think the problem is because you are subclassing UITableViewController instead of UIViewController.
you need to put UIViewController as a subclass and connect IBoutlet of UITableview in XIB with its delegare. your TableVIew in UIView of XIB so you just connect fileOWner to UIView as a View and UITableview with your TableView Outlate.
#interface MySubscriptionsViewController : UIViewController<UITableViewDelegate, UITableViewDataSource>
OR
else there you remaining some referance of old copy you trying with restart xcode and remove catch or clean derive data
I just had the same issue; I fixed it by subclassing my newly created viewController file.
I was subclassing my newly created tableView file by mistake.
Or
If you want the table view to be the root view in your initial view (it will fill up the whole screen with cells) then you will delete the view in the project outline. second you will control drag the table view in the project outline to the menu (above it) and then you will click delegate for the outlet and do the same for the data source. finally you will open the table view controller file and add UITableViewDelegate and UITableViewDataSource so that it looks like this (using your created name of course).
class MainMenuTableViewController: UITableViewController, UITableViewDelegate, UITableViewDataSource
Hope this helps.
I am trying to create a table view pragmatically(no xib and no storyboards), but the food array isn`t showing up in table view at all. I will post all my code in view controller.

Looks like you never assign your table view to your controller, add
self.tableView = tableView
as a second line in viewDidLoad
You need to set the tableView's delegate.
From Apple's documentation:
A UITableView object must have an object that acts as a data source and an object that acts as a delegate
Make sure cellForRowAtIndexPath is actually being called (use NSlog or breakpoint to check), if not, you have not set the UITableViewController's tableView to the tableView it is controlling, or you have not set your dataSource Delegate.
I'm making my first app and I’m using XCode 4 with a Storyboard. Thanks to this place, lots of tutorials, Apple’s archives databases and a bit of me, I’m slowly getting the basics together. It’s an app populated from a plist. The plist is an array with dictionaries, the dictionarires containing stings with info about different red wines in Norway. First, the plist populates a TableView. I’m using NSSortDescritor to sort the TableView and added a button to the navigation bar for resorting if I want it displayed by another value. It looks like this:
RootTableViewController.h:
#import <UIKit/UIKit.h>
#interface RootTableViewController : UITableViewController <UIActionSheetDelegate> {
NSMutableArray *sortedObjects;
}
-(IBAction)sortButtonPressed:(id)sender;
#end

#import "RootTableViewController.h"
#import "ObjectCell.h"
#import "DetailViewController.h"

#end

{
UIActionSheet *sort = [[UIActionSheet alloc]
//InitWithStyle etc for sheet
}
-(void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex
{
NSSortDescriptor *sortDesc;
if (buttonIndex == 0) {
sortDesc = [[NSSortDescriptor alloc] initWithKey:#"Name" ascending:YES];
[sortedWines sortUsingDescriptors:[NSArray arrayWithObject:sortDesc]];
}
if (buttonIndex == 1) {
sortDesc = [[NSSortDescriptor alloc] initWithKey:#"Country" ascending:YES];
[sortedWines sortUsingDescriptors:[NSArray arrayWithObject:sortDesc]];
}
[self.tableView reloadData];
}
- (void)viewDidLoad
{
[super viewDidLoad];

sortedObjects = [[NSMutableArray alloc]initWithContentsOfFile:myfile];

//Then the selected object is sent to the DetailViewController in this segue:

NSIndexPath *selectedRowIndex = [self.tableView indexPathForSelectedRow];
DetailViewController *detailViewController = [segue destinationViewController];
detailViewController.selectedObject = [sortedObjects objectAtIndex:selectedRowIndex.row];
}
}
#end
Then the DetailViewController recieves the selected object to populate the Labels and ImageViews with the data from it.
DetailViewController.h:
#import <UIKit/UIKit.h>
#interface DetailViewController : UIViewController
#property (nonatomic, strong) IBOutlet UILabel *districtLabel;
#property (nonatomic, strong) IBOutlet UILabel *countryLabel;
#property (nonatomic, strong) IBOutlet UIImageView *bottleImageView;

#synthesize districtLabel,countryLabel,bottleImageView;
#synthesize selectedObject;

if (self) {

}
return self;
}
- (void)viewDidAppear:(BOOL)animated
{
self.title = [selectedObject valueForKey:#"Name"];
[super viewDidAppear:animated];
}
- (void)viewDidLoad
{
[super viewDidLoad];
districtLabel.text = [selectedObject valueForKey:#"District"];
countryLabel.text = [selectedObject valueForKey:#"Country"];
bottleImageView.image = [UIImage imageNamed:[selectedObject valueForKey:#"Image"]];
self.navigationController.navigationBar.translucent = YES;
self.wantsFullScreenLayout = YES;
//Then I’ve added recognizers for left and right swiping:
UISwipeGestureRecognizer *leftGesture = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:#selector(swipeDetectedLeft:)];
leftGesture.direction = UISwipeGestureRecognizerDirectionLeft;
[self.view addGestureRecognizer:leftGesture];
UISwipeGestureRecognizer *rightGesture = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:#selector(swipeDetectedRight:)];
rightGesture.direction = UISwipeGestureRecognizerDirectionRight;
[self.view addGestureRecognizer:rightGesture];
}
//And the voids to handle the swipes:
- (void)swipeDetectedRight:(UISwipeGestureRecognizer *)sender
{
//Access previous cell in TableView
}
- (void)swipeDetectedLeft:(UISwipeGestureRecognizer *)sender
{
//Access next cell in TableView
}
//Some more besic code for the view..
#end
As you can see, I’ve added UISwipeGestureRecognizers in the DetailViewController, because I want to reload it with data from the previous cell to when swiped to the right, and next cell when swiped to the left. Now I have no idea how to handle the voids for swipe detected, how can I reach selectedRowIndex from DetailView and swipe through cells? I’m new to programming, have been trying to figure this out for a long time now, so code examples would be great so the answer don't lead to 100 new questions if you know what I mean. Thank you so much if you can help me.
One way to go about this is to pass the "sorted" datasource array to the DetailViewController and the indexpath through the "prepareForSegue" method.
RootTableViewController.h:
- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {
if ([[segue identifier] isEqualToString:#"DetailSegue"]) {
NSIndexPath *selectedRowIndex = [self.tableView indexPathForSelectedRow];
DetailViewController *detailViewController = [segue destinationViewController];
detailViewController.selectedObject = [sortedObjects objectAtIndex:selectedRowIndex.row];
//added code
detailViewController.detailsDataSource = [[NSArray alloc]initWithArray:sortedObjects];
detailViewController.detailIndex = selectedRowIndex.row;
}
}
Then you could reload the UI elements of the DetailViewController.
Here is the declaration of the new properties.
DetailViewController.h:
#import <UIKit/UIKit.h>
#interface DetailViewController : UIViewController
#property (nonatomic, strong) IBOutlet UILabel *districtLabel;
#property (nonatomic, strong) IBOutlet UILabel *countryLabel;
#property (nonatomic, strong) IBOutlet UIImageView *bottleImageView;
#property (nonatomic, strong) NSString *selectedObject;
// added code
#property (strong, nonatomic) NSArray *detailsDataSource;
#property int detailIndex;
#end
Don't forget to synthesize the new properties
#synthesize detailsDataSource,detailIndex;
//And the voids to handle the swipes:
- (void)swipeDetectedRight:(UISwipeGestureRecognizer *)sender
{
//Access previous cell in TableView
if (detailIndex != 0) // This way it will not go negative
detailIndex--;
districtLabel.text = [[detailsDataSource objectAtIndex: detailIndex] valueForKey:#"District"]];
countryLabel.text = [[detailsDataSource objectAtIndex: detailIndex] valueForKey:#"Country"];
bottleImageView.image = [UIImage imageNamed:[[detailsDataSource objectAtIndex: detailIndex] valueForKey:#"Image"]];
}
- (void)swipeDetectedLeft:(UISwipeGestureRecognizer *)sender
{
//Access next cell in TableView
if (detailIndex != [detailsDataSource count]) // make sure that it does not go over the number of objects in the array.
detailIndex++; // you'll need to check bounds
districtLabel.text = [[detailsDataSource objectAtIndex: detailIndex] valueForKey:#"District"]];
countryLabel.text = [[detailsDataSource objectAtIndex: detailIndex] valueForKey:#"Country"];
bottleImageView.image = [UIImage imageNamed:[[detailsDataSource objectAtIndex: detailIndex] valueForKey:#"Image"]];
}
//Some more besic code for the view..
#end
Give this a try it might work for you. Otherwise, I think you might want to take a look at Scrollview and "paging." iPhone/iPad users are used to this UI design, and you might be able to modify it to fit what you are doing.

If I change the code of ViewController.m from
_tableView.dataSource = ds;
to
_tableView.dataSource = self;
, then it's ok. (Of course, after DataSource methods had been appended to ViewController.m)
I cannot find any problems, help me and thanks in advance.
If this is ARC you have to create an instance variable or a #property for your dataSource.
You allocate your dataSource ds as a local variable. But the dataSource property of the tableView does not retain ds. So at the end of viewDidLoad ARC will release ds and it gets deallocated.
save ds as a property of your viewController. like this:
#interface ViewController : UIViewController <UITableViewDelegate>
#property (strong, nonatomic) UITableView *tableView;
#property (strong, nonatomic) DS1 *dataSource;
#end
- (void)viewDidLoad
{
[super viewDidLoad]; // <-- !!!
self.dataSource = [[DS1 alloc] init];
_tableView = [[UITableView alloc] initWithFrame:CGRectMake(0, 100, 320, 200) style:UITableViewStylePlain];
_tableView.delegate = self;
_tableView.dataSource = self.dataSource;
[self.view addSubview:_tableView];
}
I have setup a table view controller and connected a sub view so when I click on the rows the new subview appears. I followed a few tutorials step by step, but from some reason, nothing comes up when I click on the rows (the row is being selected though).
Here is my main view controller:
#interface TableViewsViewController : UIViewController <UITableViewDelegate, UITableViewDataSource> {
IBOutlet UITableView *tblSimpleTable;
IBOutlet UINavigationBar *navBar;
NSArray *arryData;
NSMutableArray *listOfItems;
}
#property (nonatomic, retain) IBOutlet UITableView *tblSimpleTable;
#property (nonatomic, retain) IBOutlet UINavigationBar *navBar;
#property (nonatomic, retain) NSArray *arryData;
#property (nonatomic, retain) NSMutableArray *listOfItems;
.m (relevant portions)
// Customize the appearance of table view cells.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle: UITableViewCellStyleValue1 reuseIdentifier:CellIdentifier];
}
NSDictionary *dictionary = [listOfItems objectAtIndex:indexPath.section];
NSArray *array = [dictionary objectForKey:#"Computers"];
NSString *cellValue = [array objectAtIndex:indexPath.row];
cell.textLabel.text = cellValue;
return cell;
}
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *) indexPath
{
NSDictionary *dictionary = [listOfItems objectAtIndex:indexPath.section];
NSArray *array = [dictionary objectForKey:#"Computers"];
NSString *selectedCountry = [array objectAtIndex:indexPath.row];
//Initialize the detail view controller and display it.
DetailViewController *dvController = [[DetailViewController alloc] initWithNibName:#"DetailView" bundle:[NSBundle mainBundle]];
dvController.selectedComputer = selectedCountry;
[self.navigationController pushViewController:dvController animated:YES];
dvController = nil;
}
And the subview controller:
.h
#interface DetailViewController : UIViewController {
IBOutlet UILabel *lblText;
NSString *selectedComputer;
}
#property (nonatomic, retain) IBOutlet UILabel *lblText;
#property (nonatomic, retain) NSString *selectedComputer;
#end
.m
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view from its nib.
//Display the selected country.
lblText.text = selectedComputer;
//Set the title of the navigation bar
self.navigationItem.title = #"Selected Computer";
}
I am pretty sure everything is well connected in IB.
Thanks for any help!
Is the table view inside a navigation controller. You can put a breakpoint on
[self.navigationController pushViewController:dvController animated:YES];
and take a loot at the self.navigationController property. if it is nil, you will not be able to push anything onto it but it will not give you an error as sending a message to nil will merely return nil in most cases.
Might be a small over look. If you created your DetailedViewController from a template and you check to create a nib file for it, the nib file should have the same name as the .h and .m files. So check for the name of your nib class. It might should be:
DetailViewController *dvController = [[DetailViewController alloc] initWithNibName:#"DetailViewController" bundle:nil];
P.S. use self. here:
self.dvController = nil;
Otherwise you will leak.
