We need to customize the viewDidLoad method in order to build the UISearchBar on the friend picker view.

- (void)viewDidLoad { [super viewDidLoad]; [self addSearchBarToFriendPickerView]; }

The previous code shows the new viewDidLoad method with the new, not yet defined method addSearchBarToFriendPickerView. The new method initializes the searchBar, only if this one is set to nil. After the initialization is complete, the searchBar is added to the view container.

The following snippet shows the addSearchBarToFriendPickerView implementation.

- (void)addSearchBarToFriendPickerView { if (self.searchBar == nil) { CGFloat searchBarHeight = 44.0; self.searchBar = [[UISearchBar alloc]initWithFrame:CGRectMake(0, 0, self.view.bounds.size.width,searchBarHeight)]; self.searchBar.autoresizingMask =self.searchBar.autoresizingMask |UIViewAutoresizingFlexibleWidth; self.searchBar.delegate = self; self.searchBar.showsCancelButton = YES; // Adding the searchBar to the current view and resize thefriends' list table view [self.canvasView addSubview:self.searchBar]; CGRect newFrame = self.view.bounds; newFrame.size.height -= searchBarHeight; newFrame.origin.y = searchBarHeight; self.tableView.frame = newFrame; } }
