iPhone fill values for UIPickerView -


i've created uipickerview, displays on button click. question how fill in rowitems

uiactionsheet *actionsheet = [[uiactionsheet alloc] initwithtitle:@"select location"                                                              delegate:self                                                     cancelbuttontitle:@"cancel"                                                destructivebuttontitle:nil                                                     otherbuttontitles:nil];      [actionsheet setactionsheetstyle:uiactionsheetstyleblacktranslucent];     uipickerview *pickerview = [[uipickerview alloc] initwithframe:cgrectmake(0,100,0,0)];     pickerview.showsselectionindicator = yes;     pickerview.datasource = self;     pickerview.delegate = self;     [actionsheet addsubview:pickerview];     [pickerview release];     uisegmentedcontrol *closebutton = [[uisegmentedcontrol alloc] initwithitems:[nsarray arraywithobject:nslocalizedstring(@"done", @"")]];     closebutton.momentary = yes;     closebutton.frame = cgrectmake(260, 7.0f, 50.0f, 30.0f);     closebutton.segmentedcontrolstyle = uisegmentedcontrolstylebar;     closebutton.tintcolor = [uicolor blackcolor];     [closebutton addtarget:self action:@selector(dismissactionsheet:) forcontrolevents:uicontroleventvaluechanged];     [actionsheet addsubview:closebutton];        [closebutton release];     [actionsheet showinview:self.view];     [actionsheet setbounds:cgrectmake(0, 0, 320, 485)];

and how value when "done" clicked.

you've set delegate of alert, , picker already. have implement them. don't fill in data picker, picker asks delegate data.

you need mandatory functions defined in these 3 protocols.

uipickerviewdelegate
uipickerviewdatasource
uiactionsheetdelegate

you have implement -(ibaction)dismissactionsheet:(uibutton *)sender too.

and how value when "done" clicked.

i store value instance variable every time picker changes, , once done button clicked assign data model.

edit: if want learn rid of copy&paste solution , try implement on own. ymmv.
