    <p>I am using a UISearchDisplayController in my app. Since iOS 7 a strange bugg occurs, when klicking on the searchBar and the keyboard is displayed, the app gives several errors if the user decides to klick at the searchBar once more while the "searchField" is empty.</p> <p>The bugg is discussed in this thread: <a href="https://stackoverflow.com/questions/17777928/uisearchbar-cgcontext-error">UISearchBar CGContext ERROR</a></p> <p>Now I have 2 questions: is there any way to solve tihs problem? And if not, can you upload the app to the App Store with this bugg in the system? </p> <p>Regards</p> <p>My code:</p> <pre><code>- (void)viewDidLoad { [super viewDidLoad]; if ([self systemVersionGreaterThanOrEqualTo:@"7.0"]) { [[UISearchBar appearance]setSearchFieldBackgroundImage:[UIImage imageNamed:@"searchbar_bg"] forState:UIControlStateNormal]; self.navigationItem.titleView = searchBar; } } - (BOOL)searchBarShouldBeginEditing:(UISearchBar *)searchBar { [self.searchDisplayController setActive:YES animated:NO]; // Hand over control to UISearchDisplayController during the search // searchBar.delegate = (id &lt;UISearchBarDelegate&gt;)self.searchDisplayController; return YES; } - (void) searchDisplayControllerDidBeginSearch:(UISearchDisplayController *)controller { // Un-hide the navigation bar that UISearchDisplayController hid [self.navigationController setNavigationBarHidden:NO animated:NO]; } - (void) searchDisplayControllerWillEndSearch:(UISearchDisplayController *)controller { searchBar = (UISearchBar *)self.navigationItem.titleView; // Manually resign search mode [searchBar resignFirstResponder]; // Take back control of the search bar searchBar.delegate = self; } </code></pre>

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.
