iphone - How to add a UIToolbar to a UITableViewController programmatically? -

i have opted use uitableviewcontroller without nib. need uitoolbar @ bottom 2 buttons. simplest way of doing that?

p.s. know can use uiviewcontroller , add uitableview want things consistent across app.

can help?

i saw following example , not sure on validity:

(void)viewwillappear:(bool)animated {     [super viewwillappear:animated];      //initialize toolbar      toolbar = [[uitoolbar alloc] init]; toolbar.barstyle = uibarstyledefault;      //set toolbar fit width of app.      [toolbar sizetofit];      //caclulate height of toolbar      cgfloat toolbarheight = [toolbar frame].size.height;      //get bounds of parent view      cgrect rootviewbounds = self.parentviewcontroller.view.bounds;      //get height of parent view.      cgfloat rootviewheight = cgrectgetheight(rootviewbounds);      //get width of parent view,      cgfloat rootviewwidth = cgrectgetwidth(rootviewbounds);      //create rectangle toolbar      cgrect rectarea = cgrectmake(0, rootviewheight - toolbarheight, rootviewwidth, toolbarheight);      //reposition , resize receiver      [toolbar setframe:rectarea];      //create button      uibarbuttonitem *infobutton = [[uibarbuttonitem alloc] initwithtitle:@"back"                                                                    style:uibarbuttonitemstylebordered                                                                    target:self                                                                    action:@selector(info_clicked:)];      [toolbar setitems:[nsarray arraywithobjects:infobutton,nil]];      //add toolbar subview navigation controller.     [self.navigationcontroller.view addsubview:toolbar];      [[self tableview] reloaddata]; }  (void) info_clicked:(id)sender {      [self.navigationcontroller popviewcontrolleranimated:yes];     [toolbar removefromsuperview];  } 

the simpler thing build project on top of uinavigationcontroller. has toolbar, it's hidden default. can reveal toggling toolbarhidden property, , table view controller able use long it's in navigation controller hierarchy.

in app delegate, or in object app delegate passes control to, create navigation controller uitableviewcontroller root view controller:

- ( void )application: (uiapplication *)application           didfinishlaunchingwithoptions: (nsdictionary *)options {     mytableviewcontroller         *tableviewcontroller;     uinavigationcontroller        *navcontroller;      tableviewcontroller = [[ mytableviewcontroller alloc ]                                  initwithstyle: uitableviewstyleplain ];     navcontroller = [[ uinavigationcontroller alloc ]                            initwithrootviewcontroller: tableviewcontroller ];     [ tableviewcontroller release ];      /* ensure toolbar visible */     navcontroller.toolbarhidden = no;     self.navigationcontroller = navcontroller;     [ navcontroller release ];      [ self.window addsubview: self.navigationcontroller.view ];     [ self.window makekeyandvisible ]; } 

then set toolbar items in mytableviewcontroller object:

- ( void )viewdidload {     uibarbuttonitem            *buttonitem;      buttonitem = [[ uibarbuttonitem alloc ] initwithtitle: @"back"                                             style: uibarbuttonitemstylebordered                                             target: self                                             action: @selector( goback: ) ];     self.toolbaritems = [ nsarray arraywithobject: buttonitem ];     [ buttonitem release ];      /* ... additional setup ... */ }
