Problem
Some third party library is used. Some views disappear after their translatesAutoresizingMaskIntoConstraints
are set to NO
.
Don't have other autoresizingMask
setting for my views in my own code; in the library, the autoresizingMask
parts of code have been removed too. Instead, explicit bounds/center/frame are set for those views. There're no nib files, views are all programmatically created.
I know some other people solve similar problem by giving a thorough autolayout constraints set, but in my case, I mean to turn off autolayout and do it manually. No idea when autolayout is turned on.
Some people say that "by default, as your app launches, autolayout is switched off, and the system behaves as in iOS 5 and before. But if, at any time while your app runs, the system sees an autolayout constraint (generated in code or by the loading of a nib that has “Use autolayout” checked), the autolayout system is switched on, and from then on you’re running under autolayout." (Programming iOS 6 by Matt Neuberg, pages 383-384), but in my project I don't think there's any autolayout constraints left.
The code is bulky, but will upload some skeleton if necessary.
Thank you for tips!
