ios - setHidden not working for UIView -

i have subclass of uiview called invitedview. instantiated in viewdidload this:

viewcontroller.m

invitedview = [[invitedview alloc] initwithframe:cgrectmake(100, 244, 120, 80)]; invitedview.backgroundcolor = [uicolor colorwithred:156.0f/255.0f green:214.0f/255.0f blue:215.0f/255.0f alpha:0.9f];       [self.view addsubview:invitedview]; [invitedview sethidden:yes]; 

the class looks this:

invitedview.m

#import "invitedview.h" #import "appdelegate.h" #import "viewcontroller.h"  @class viewcontroller;  @interface invitedview() {     uibutton *accept;     uibutton *decline;     uilabel *question;     uiview *gray;     viewcontroller *myviewcontroller; }  @end  @implementation invitedview  - (id)initwithframe:(cgrect)frame {     self = [super initwithframe:frame];     if (self) {         gray = [[uiview alloc] initwithframe:frame];          nsstring *holduser = [(appdelegate*)[[uiapplication sharedapplication] delegate] invitedby];          [self addsubview:gray];          accept = [[uibutton alloc] init];         decline = [[uibutton alloc] init];         question = [[uilabel alloc] init];         question.text = [[nsstring alloc] initwithformat:@"you have been invited group game %@", holduser];         question.numberoflines = 0;         question.textalignment = nstextalignmentcenter;         question.textcolor = [uicolor colorwithred:211.0f/255.0f green:243.0f/255.0f blue:219.0f/255.0f alpha:1.0f];          accept.backgroundcolor = [uicolor clearcolor];         accept.frame = cgrectmake(20, gray.frame.size.height / 2, (gray.frame.size.width / 2) - 10, (gray.frame.size.height / 2) - 20);         decline.backgroundcolor = [uicolor clearcolor];         decline.frame = cgrectmake((gray.frame.size.width / 2) + 10, (gray.frame.size.width / 2) - 20, (gray.frame.size.width / 2) - 20, (gray.frame.size.height / 2) - 20);         question.frame = cgrectmake(20, 20, gray.frame.size.width, (gray.frame.size.height / 2) - 20);         [question setfont:[uifont fontwithname:@"helveticaneue-bold" size:18.0]];          [accept addtarget:myviewcontroller action:@selector(acceptinvite) forcontrolevents:uicontroleventtouchupinside];         [decline addtarget:myviewcontroller action:@selector(declineinvite) forcontrolevents:uicontroleventtouchupinside];         [gray addsubview:accept];         [gray addsubview:decline];         [gray addsubview:question];      }     return self; }  @end 

the method view supposed shown in view controller showing view. ends getting called, can verify log messages happen way until sethidden function:

viewcontroller.m

- (void)dosomethingwiththenewvalueofflagforhid {     nslog(@"issettingtheview******");     dispatch_async(dispatch_get_main_queue(), ^(void){         nslog(@"issettingtheviewmu2******");         [invitedview sethidden:no];     }); } 

i know why invitedview isn't being shown after [invitedview sethidden:no]. gets way sethidden, , nothing happens. appreciate help, in advance.

in viewdidload, change line

[invitedview sethidden:no]; 

to make sure can see view (frame ok, no view above ...)
