Change title of bar button in UIImagePickerController's navigation bar -

my question simple: how can change change title of bar button in uiimagepickercontroller's navigation bar? created controller uiimagepickercontroller (triggered pressure onto button) , tried modify properties:

- (ibaction)choosefromroll:(id)sender {      if ([uiimagepickercontroller issourcetypeavailable: uiimagepickercontrollersourcetypesavedphotosalbum]){         uiimagepickercontroller *imagepicker =         [[uiimagepickercontroller alloc] init];          imagepicker.navigationbar.tintcolor = [uicolor colorwithred:0.42 green:0.18 blue:0.66 alpha:1.0];         //imagepicker.navigationitem.title = @"scegli foto profilo";          imagepicker.delegate = self;         imagepicker.sourcetype =         uiimagepickercontrollersourcetypephotolibrary;         imagepicker.mediatypes = [nsarray arraywithobjects:                                   (nsstring *) kuttypeimage,                                   nil];         imagepicker.allowsediting = no;           [imagepicker.navigationcontroller.navigationitem.rightbarbuttonitem  settitle:@"annulla"];         [self presentviewcontroller:imagepicker animated:yes completion:nil];     } } 

but nothing changed, navigation bar correctly modified.

here's code function willshowviewcontroller:

- (void) navigationcontroller:(uinavigationcontroller *)navigationcontroller willshowviewcontroller:(uiviewcontroller *)viewcontroller animated:(bool)animated{      uilabel *label = [[uilabel alloc] initwithframe:cgrectmake(0, 0, 320, 30)];     label.textalignment = 2;     label.frame = cgrectmake(label.frame.origin.x, label.frame.origin.y, label.frame.size.width-200,label.frame.size.height);     label.adjustsfontsizetofitwidth = yes;     label.font = [uifont fontwithname:@"futura" size:15.0];     [label setfont:[uifont boldsystemfontofsize:16.0]];     [label setbackgroundcolor:[uicolor clearcolor]];     [label settextcolor:[uicolor whitecolor]];     [label settext:@"scegli foto profilo"];      [navigationcontroller.navigationbar.topitem settitleview:label.viewforbaselinelayout];      [navigationcontroller.navigationbar.topitem.rightbarbuttonitem settitle:@"annulla"];    } 

can tell me where's mistake?

thanks

here code snippet twicking title of navigation bar in uiimage picker.

- (void)navigationcontroller:(uinavigationcontroller *)navigationcontroller willshowviewcontroller:(uiviewcontroller *)viewcontroller animated:(bool)animated { uinavigationitem *ipcnavbartopitem;  // add done button right side of nav bar uibarbuttonitem *donebutton = [[uibarbuttonitem alloc] initwithtitle:@"photos"                                                                style:uibarbuttonitemstyleplain                                                                target:self                                                                action:@selector(saveimages:)];  uinavigationbar *bar = navigationcontroller.navigationbar; [bar sethidden:no]; ipcnavbartopitem = bar.topitem; ipcnavbartopitem.title = @"photos"; ipcnavbartopitem.rightbarbuttonitem = donebutton; } 

hope out.

edit:

the answer first question yes can use ibaction or use method provided above create button, both should work. if using inaction, make sure declare controller within can make appear , dismiss within action method. answer second question if want change title of view presented when image picker photo album presented need create new subview , pop allow user select desired image can change title way did above. lengthy process, not recommend it. answer third question, try using following code snippet declare button,

[btn.titlelabel setfont:[uifont boldsystemfontofsize:13]]; 

where btn name of button , can modify font name , size. hope answers can you. luck , let me know if need more help.
