    <p>When i've created a UITableView in the code en add it as a subview in the code it is all working fine. There is green tableview visible. Example of the code i've created for that.</p> <pre><code>- (void)getOverviewTable { // Adding the TableView OverviewTableViewController *overviewTableViewController = [[OverviewTableViewController alloc] init]; UITableView *overviewTableView = [[UITableView alloc] initWithFrame:(CGRectMake(0, 0, self.view.frame.size.width, self.view.frame.size.height))]; // Set the datasource and delegete will come here [overviewTableView setBackgroundColor:[UIColor greenColor]]; [self.view addSubview:overviewTableView]; } </code></pre> <p>But after i've set the DataSource and the Delegete for the TableView i will receive a warning. The code in total for reaching it is as follows:</p> <pre><code>- (void)getOverviewTable { // Adding the TableView OverviewTableViewController *overviewTableViewController = [[OverviewTableViewController alloc] init]; UITableView *overviewTableView = [[UITableView alloc] initWithFrame:(CGRectMake(0, 0, self.view.frame.size.width, self.view.frame.size.height))]; // Set the datasource and delegete will come here [overviewTableView setDataSource:overviewTableViewController]; [overviewTableView setDelegate:overviewTableViewController]; [overviewTableView setBackgroundColor:[UIColor greenColor]]; [self.view addSubview:overviewTableView]; } </code></pre> <p>The most of the time it is just an EXC_BAD_ACCESS error, but sometimes it shows me the following error.</p> <pre><code>[UITransitionView numberOfRowsInSection:]: unrecognized selector sent to instance </code></pre> <p>The 'OverViewTableViewController' is replaced by just an empty UITableViewController class but the error is still showing up.</p> <p>(Point of the application is an fullscreen takeover which has to be swiped away to see the tableview underneath it)</p> <p>Edit:</p> <p>The function is called from the viewDidLoad function</p> <pre><code>- (void)viewDidLoad { [super viewDidLoad]; // Do any additional setup after loading the view. [self.view setBackgroundColor:[UIColor colorWithPatternImage:[UIImage imageNamed:@"bg.jpg"]]]; // Setting the home takeover [self setHomeTakeOver]; // Wait one seconde before we load the tableview [self getOverviewTable]; //[self performSelector:@selector(getOverviewTable) withObject:nil afterDelay:1.0]; } </code></pre>

    3. COThis is usually due to calling methods on object that has been deallocated. If memory the object points to is not already allocated by some other object you receive bad access. If it is allocated for instance by some UITransitionView it will report unrecognized selector. Try analyzer tool, it might find you the overreleased object if that is the case.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
