ios - UIScrollView programmatically add buttons and scroll -
i'm new ios , objective-c. please little bit patient me.
the functionality in app, i'm trying develop, small scrolling toolbar, contains several buttons, state toggling buttons. there button above toolbar slides in , out toolbar. second functionality achieved successfully, using view whole setup , when slide button touch event animates whole view , down.
for scrollview, wanted add buttons programmatically, hence drew outlet class , tried adding self created button subview. cannot see button. nor can observe scrollview sliding.
the following way i'm adding button: also, total view above functionality less in size total view controller
uibutton *button = [[uibutton alloc] init]; button.titlelabel.text = @"hello"; [_scrolltop setcontentsize:self.view.frame.size]; [_scrolltop addsubview:button]; the 2 images down, hope, should understand functionality i'm trying develop. if aware of existence of similar functionality, please direct me.
edit: code totally is

if understood question correctly need have view should show , collapse on button click event. when view shown, should have scrollable list of buttons. , asking show many buttons scrollview.
