ios - backBarButtonItem in navigation controller not showing up -

-

i started xcode project navigationviewcontroller template. , now, when push view, view comes edit button default , no bar button. have commented out editbutton code , corresponding setediting delegate method. can not button show up. doing wrong?

pushing new view:

playlistviewcontroller *playlistviewcontroller = [[playlistviewcontroller alloc] init]; playlistviewcontroller.managedobjectcontext = self.managedobjectcontext;  [self.navigationcontroller pushviewcontroller:playlistviewcontroller animated:yes]; [playlistviewcontroller release];

in playlistviewcontroller:

- (void)viewdidload {     [super viewdidload];      self.title = @"";      // self.navigationitem.leftbarbuttonitem = self.editbuttonitem;      // doesn't matter if here or not     self.navigationitem.hidesbackbutton = false;      uibarbuttonitem *addbutton = [[uibarbuttonitem alloc] initwithbarbuttonsystemitem:uibarbuttonsystemitemadd target:self action:@selector(insertnewobject)];     self.navigationitem.rightbarbuttonitem = addbutton;     [addbutton release]; }

when tell uinavigationcontroller pushviewcontroller, automatically sets navigationitem.leftbarbuttonitem button title of previous uiviewcontroller's title.

if no title set, default text "back".

if title set "", no button display @ all.

self.title = @"";

try changing text , button should match text set here.

or can manually override text of leftbarbuttonitem new uiviewcontroller.

-
i got following problem: i have object called tempscore game. this object blitted canvas renderer via copypixels method. object not display object. it's score-object (self made). score-object extends object called basicblitarrayobject. basicblitarrayobject extends eventdispatcher (therefore no display object). i tried apply several different tweenlite-plugins tempscore-object (i.e. transformaroundcenter, colormatrixfilter, etc.). nothing happens. absolutely nothing. sometimes error messages (when plugin requires display object , object not display object). far good. according greensock (maker of tweenlite) engine can tween numeric property of object. when plugin transformaroundcenter requires display object tweening have modify plugin working non-display object (tempscore). can't because it's way hard me. my game rests upon code: http://www.8bitrocket.com/book/ch11_blastermines.zip try apply tweenlite object called tempmine inside game class blastermines.
