Problem adding UIBarButtonItems to a ToolBar
cocoa-touch, iphone, objective-c, uikit, uitoolbar
Solution
I found out in the documentation of Apple there is small paragraph explaining the UIToolBar. In this paragraph there is a very tiny sentence stating: "[..] When displayed, this toolbar obtains its current set of items from the toolbarItems property of the active view controller [..]" But they don't explain that view first has to be active to obtain these buttons. So that means that the UIToolBar is ready to retrieve it's Buttons on viewDidAppear and NOT on viewDidLoad message.
- (void)viewDidAppear:(BOOL)animated {
[[self tableView] reloadData];
[[self navigationController] setToolbarHidden: NO animated:YES];
UIBarButtonItem * logoutButton = [[[UIBarButtonItem alloc] initWithTitle:@"Log out" style:UIBarButtonItemStylePlain target:self action:@selector(logOut:)]autorelease];
NSMutableArray * arr = [NSMutableArray arrayWithObjects:logoutButton, nil];
[self setToolbarItems:arr animated:YES];
[super viewDidAppear:animated];
}
Problem
I have a UINavigationController with a UITableViewController in it. I want to show a ToolBar on the bottom with UIBarButtonItem's. The ToolBar is showing up, but the buttons won't appear. Anyone knows why? ``` - (void)viewDidLoad { [super viewDidLoad]; [[self navigationItem] setTitle:@"Selections List"]; [[self navigationItem] setRightBarButtonItem:[[[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemAdd target:self action:@selector(addProjectSearch:)] autorelease]]; [[self navigationItem] setLeftBarButtonItem:[self editButtonItem]]; [[super tableView] setDataSource: self]; [[super tableView] setDelegate: self]; //Toolbar UIBarButtonItem * logoutButton = [[[UIBarButtonItem alloc] initWithTitle:@"Log out" style:UIBarButtonItemStylePlain target:self action:@selector(logOut:)]autorelease]; NSMutableArray * arr = [NSMutableArray arrayWithObjects:logoutButton, nil]; [[self navigationController] setToolbarHidden: NO animated:YES]; [[self navigationController] setToolbarItems:arr animated:YES]; } ```
