ios - TextField not being added to ScrollView -


when input following code, textfields added not being displayed in scrollview:

.h

@interface firstviewcontroller : uiviewcontroller <uiscrollviewdelegate> @property (strong, nonatomic) iboutlet uiscrollview *scrollview; @property (strong, nonatomic) uitextfield *firstfield; @property (strong, nonatomic) uitextfield *secondfield; @property (strong, nonatomic) uitextfield *thirdfield;

.m (viewdidload)

self.firstfield.placeholder = @"first"; self.firstfield.textalignment = nstextalignmentcenter; self.firstfield.font = [uifont fontwithname:@"helvetica neue light" size:50.0];  self.secondfield.placeholder = @"second"; self.secondfield.textalignment = nstextalignmentcenter; self.secondfield.font = [uifont fontwithname:@"helvetica neue light" size:50.0];  self.thirdfield.placeholder = @"third"; self.thirdfield.textalignment = nstextalignmentcenter; self.thirdfield.font = [uifont fontwithname:@"helvetica neue light" size:50.0];  [self.scrollview addsubview:self.firstfield]; [self.firstfield autopinedgestosuperviewedgeswithinsets:uiedgeinsetszero excludingedge:aledgeright]; [self.firstfield automatchdimension:aldimensionwidth todimension:aldimensionwidth ofview:self.scrollview]; [self.firstfield automatchdimension:aldimensionheight todimension:aldimensionheight ofview:self.scrollview];  [self.scrollview addsubview:self.secondfield]; [self.secondfield autopinedge:aledgeleft toedge:aledgeright ofview:self.firstfield]; [self.secondfield automatchdimension:aldimensionwidth todimension:aldimensionwidth ofview:self.scrollview]; [self.secondfield automatchdimension:aldimensionheight todimension:aldimensionheight ofview:self.scrollview];  [self.scrollview addsubview:self.thirdfield]; [self.thirdfield autopinedge:aledgeleft toedge:aledgeright ofview:self.secondfield]; [self.thirdfield autopinedgestosuperviewedgeswithinsets:uiedgeinsetszero excludingedge:aledgeleft]; [self.thirdfield automatchdimension:aldimensionwidth todimension:aldimensionwidth ofview:self.scrollview]; [self.thirdfield automatchdimension:aldimensionheight todimension:aldimensionheight ofview:self.scrollview];  self.automaticallyadjustsscrollviewinsets = no;

i have self.scrollview within scrollview way (in pageviewcontroller). using purelayout position text fields, , i'm pretty sure way did correct. there i'm missing?

yes missing code,if wan't add uitextfield programmatically must set size , position on you're view, that:

self.firstfield.frame = cgrectmake(10, 200, 300, 40);

i hope you.
