i have read in several other posts topic, , it's understanding resize object when autolayout enabled, can change constant properties of constraints in code.
i have 2 buttons side side, this
[delete][ post ]
and take entire width of screen. want hide delete button views, , when happens, stretch post button take entire width of screen. in code, have:
self.postbuttonleadingconstraint.constant = self.deletebuttonleadingconstraint.constant self.deletebutton.hidden my delete button hides fine, post button stays at. doing wrong? input appreciated.
edit: if matters, buttons constrained follows:
delete button leading constrained leading edge of view
post button leading constrained trailing edge of delete button
delete , post button set equal each others' widths
both buttons have tops , buttons constrained view in, don't see how relevant.
if you're targeting ios 9 , higher i'd suggest using uistackview. super easy way, matter of adding and/or removing button from/to stack view. here's little sample understand.
