ios - UIMenuController Has Zero Frame -

i went through every other question on related topic. none helped me far.

i trying show uimenucontroller on uiview. therefore subclassed uiview , implemented required methods already. in uiviewcontroller instantiate uigesturerecognizer , add custom uiview. works fine. can handle long press gesture. uimenucontroller won't show up!

@interface copyableview : uiview @end  @implementation copyableview  - (bool)canbecomefirstresponder {     nslog(@"_can become 1. responder_");     return yes; }  - (bool)canperformaction:(sel)action               withsender:(id)sender {     nslog(@"_can perform action_");     return (action == @selector(copy:)); }  - (void)copy:(id)sender {     nslog(@"_copy_"); }  @end   @interface infoviewcontroller : uiviewcontroller  @property (nonatomic, weak) iboutlet copyableview *myview;  @end  @implementation infoviewcontroller  - (void)viewdidload {     [super viewdidload];      [self.myview addgesturerecognizer:[[uilongpressgesturerecognizer alloc] initwithtarget:self                                                                                     action:@selector(handlelongpressgesture:)]]; }  - (void)handlelongpressgesture:(uilongpressgesturerecognizer *)recognizer {     if (recognizer.state == uigesturerecognizerstatebegan)     {         nslog(@"__ %i __", [uimenucontroller sharedmenucontroller].menuvisible);          [self.myview becomefirstresponder];          uimenuitem *item = [[uimenuitem alloc] initwithtitle:@"copy"                                                       action:@selector(copy:)];         [[uimenucontroller sharedmenucontroller] setmenuitems:@[item]];         [[uimenucontroller sharedmenucontroller] settargetrect:cgrectmake(33, 33, 33, 33)                                                         inview:self.myview];         [[uimenucontroller sharedmenucontroller] setmenuvisible:yes                                                        animated:no];          nslog(@"__ %i __", [uimenucontroller sharedmenucontroller].menuvisible);         nslog(@"#### %@ ####", nsstringfromcgrect([uimenucontroller sharedmenucontroller].menuframe));     } } 

checking [uimenucontroller sharedmenucontroller].menuvisible returns true @ end of method. things seem work. still see nothing happening. frame of uimenucontroller {{0, 0}, {0, 0}} cannot understand.
