size-classes

I am using size classes to create a storyboard that can target all the various screen sizes and orientations. I have been working in the Any Width-Any Height size class. I ran into a display issue and decided to make those changes in the Compact Width - Regular Height size class. At a Later time, I was able to resolve my layout issue by making constraint changes to the Any Width-Any Height size class. How can I revert the changes made to the Compact Width - Regular Height size class so that the Any Width-Any Height size class will be used at runtime without manually reverting the changes? I

Is it possible to give a constraint a different multiplier depending on the current size class? I have a view that I want to be half the size of the screen for a regular size class width and I want it to be 80% of the size of the screen for a compact size class width. In the storyboard I have the option to add different variables for different size classes to the constraints constant value, but not it's multiplier value. It's an Equal Widths Constraint in case that is relevant. I haven't done much with adding constraints programatically so I'm hoping their might be a solution that lies down

I (hopefully) watched all the relevant WWDC2014 session videos and read the docs, so this question is mostly to confirm my suspicions, but please educate me. What I want to do is animate views using Auto Layout. That in itself is not a problem. But these animations' endpoints change with different orientations. I thought I might be able to use size classes to move the views automatically on rotation, but Apple's developer guide says that animations have to be done programmatically, and from what I can gather, size classes are an Interface-Builder-only thing. Another idea I had was using custom

This question already has an answer here: Sizing class for iPad portrait and Landscape Modes 6 answers It seems all the current iOS devices maps to the new iOS 8 size classes nicely except iPad landscape? I seem not able to figure out how to use the size class feature to draw a different scene for iPad landscape (different from iPad portrait)? Is that intended by design in Apple's mind or am I miss something about the iOS size classes? RonDiamond It appears to be Apple's intent to treat both iPad orientations as the same -- but as a number of us are finding, there are very legitimate design

I have a four buttons layout. In portrait they should be shown one above the other. In landscape they should be in two columns each with two buttons. I implement the buttons in code - really simple stuff: UIButton *btn1 = [[UIButton alloc] init]; [self.view addSubview: btn1]; UIButton *btn2 = [[UIButton alloc] init]; [self.view addSubview: btn2]; UIButton *btn3 = [[UIButton alloc] init]; [self.view addSubview: btn3]; UIButton *btn4 = [[UIButton alloc] init]; [self.view addSubview: btn4]; NSDictionary *views = NSDictionaryOfVariableBindings(btn1, btn2, btn3, btn4); [btn1
