objective c - UIScrollView not scrolling when included into viewcontroller embedded into a navigation controller -

i have made view controller embedded in navigation controller. in view controller, have inserted scroll view contains buttons , text fields. in viewdidload method, have inserted following code initialize scrollview:

[scroller setscrollenabled:yes]; [scroller setcontentsize:cgsizemake:(1000, 1000)]; 

but view not scroll. have tried same scenario without embedding view controller navigation controller , working. know problem? thanks.

write in viewdidappear. ui components willnot set in viewdidload

try,

-(void)viewdidappear:(bool)animated {     [super viewdidappear:animated];     [scroller setscrollenabled:yes];     [scroller setcontentsize:cgsizemake:(1000, 1000)]; } 

should work .
