xCode 8.0 / Constraints don't work as supposed

Hey, fellow students and mods!

I've got a question: I'm following Pasan's explanation and guiding, but my constraints don't work as they suppose to. While at preview other sizes behave badly, after compilation my initial screen is going everywhere, ignoring all the constraints.

I don't know how to fix it. I've spent a lot of time trying to find out and experiment, but it simply doesn't work.

I will appreciate any help.

Thanks!

Hey Ksenia,

Can you specify in what video/course this happened? This makes it easier for us to help. The fist thing I thought of that you might have forgotten to set the translatesAutoresizingMaskIntoConstraints to false. This can be done like this:

viewName.translatesAutoresizingMaskIntoConstraints = false

Hope this helped a bit!

Regards, Jari

Hey Jari,

Thanks for your reply. It happened at Pasan's course on building a playlist app in Objective-C, one of the last videos, where he brings all the pieces of UI together.

As well as I remember, we didn't cover translatesAutoresizingMaskIntoConstraints at all. We've done all the things using auto layout + storyboard. Could you, please, specify, where exactly should I put this property?

Thanks!

Best, Ksenia

Hey Ksenia,

I thought you where talking about a Swift course, you can forget about the translatesAutoresizingMaskIntoConstraints property since that's a Swift thing. I don't have any knowledge about Objective-C so I can't help you any further.
