objective c - Centering on a UIToolBar with a UIToolbarButton on either side -

i trying center text on uitoolbar button on either side, having problems.

i have following code:

uitoolbar *toolbar = [[uitoolbar alloc] initwithframe:toolbarinitialframe]; toolbar.barstyle = uibarstyleblacktranslucent;  uilabel * label = [[uilabel alloc] initwithframe:cgrectmake(0, 0, 200, 25)]; [label settext:@"title"]; [label setbackgroundcolor:[uicolor clearcolor]]; [label settextcolor:[uicolor whitecolor]]; [label setfont:[uifont boldsystemfontofsize:16]];    uibarbuttonitem * labelemu=[[uibarbuttonitem alloc] initwithcustomview:label];  uibarbuttonitem *cancelbutton = [[uibarbuttonitem alloc] initwithbarbuttonsystemitem:uibarbuttonsystemitemcancel target:self action:@selector(cancelalarmanddismissdatepicker:)];  uibarbuttonitem *spacer = [[uibarbuttonitem alloc] initwithbarbuttonsystemitem:uibarbuttonsystemitemflexiblespace target:nil action:nil];  uibarbuttonitem *donebutton = [[uibarbuttonitem alloc] initwithbarbuttonsystemitem:uibarbuttonsystemitemdone target:self action:@selector(setalarmanddismissdatepicker:)]; 

so want cancel button (cancelbutton) on left, title (labelemu) centered in middle, , done button (donebutton) on right. this:

|[cancel]    title    [done]| 

i hoping achieve this:

[toolbar setitems:[nsarray arraywithobjects: cancelbutton, spacer, labelemu, spacer, donebutton, nil]]; 

but unfortunately this:

|[cancel]title        [done]| 

after playing about, ive found line:

[toolbar setitems:[nsarray arraywithobjects: cancelbutton, spacer, labelemu, spacer, nil]]; 

...produces this:

|[cancel]    title          | 

where title centered, ignoring fact cancel button there. when this:

[toolbar setitems:[nsarray arraywithobjects: spacer, labelemu, spacer, donebutton, nil]]; 

...it produces this:

|        title        [done]| 

where title centered in space between far left edge , right side of done button. not ignoring done button in same way ignores cancel button.

can point me in right direction after? sorry naff ascii diagrams! :)

maybe try using:

[[uibarbuttonitem alloc] initwithtitle:@"yourtitle" style:uibarbuttonitemstyleplain target:nil action:nil]; 

it might if uitollbar in charge on label.

edit try adding:

[label sizetofit]; 

before adding tollbar
