size-classes

I am getting issues in autorotation of a UIView which is nothing but a red line of width 4 and height half of superview's height in landscape mode, and in portrait mode the height is 4 points and width is half of superview width. You can see the issue in the gif. As I rotate from landscape to portrait, the effect of autorotation is not smooth and with distortions. Here is the code. What am I doing wrong? private var myView:UIView! override func viewDidLoad() { super.viewDidLoad() // Do any additional setup after loading the view, typically from a nib. myView = UIView(frame: CGRect(x: 0, y: 0,

With Auto Layout for iPhones in Portrait, I don't want the exact same size UIImageViews for game characters on iPhone 6+ as in iPhone 4S. The 4S characters need to be smaller or else they'll look too big. Using Auto Layout how do I change image sizes between iPhones because they seem like they all change to be the same sizes regardless of constraints. I am sure that they would be smaller because when you add images, you add 3 sizes of the image: @1x, @2x, and @3x. These images make the image universal for all Apple devices. Try them out in your simulator. 来源： https://stackoverflow.com

I'm trying to figure out how to use UITraitCollection programatically, but I find it difficult to make sense of it. I'm developing for an iPad retina, in iOS 8. println(self.traitCollection) returns the following output: <UITraitCollection: 0x10df4c7f0; _UITraitNameUserInterfaceIdiom = Pad, _UITraitNameDisplayScale = 2.000000, _UITraitNameHorizontalSizeClass = Regular, _UITraitNameVerticalSizeClass = Regular, _UITraitNameTouchLevel = 0, _UITraitNameInteractionModel = 1> Which is pretty straight forward. But when I then rotate the screen, I get the exact same output. I.e., same vertical size

I have to show an imageview in a universal app ans it's size should increase as the screen design in every devices without reducing image quality. The image given to the imageview is a static image. If I use static width and height constraints using size classes it will work. But I don't think it as the correct way. If i use width & height Proportional to the superview, it increases the image height but image clarity reduced in ipads. Any suggestion will be helpfull. To make Imageviewsize respect to device for universal application , you need to give correct multipler to imageview. please

I'm tuning my UI App, but I got an issue that I can't solve. As I can see Compact height affects all iPhones under 4.7 inches, but my UI is fine except for the iPhone 4S (3.5 inches). I don't want to modify the layout for all iPhones under 4.7 inches, just the iPhone 4S, at the same time I don't want to left out this device. There's any workaround so I can set the amendments but just and only for the 3.5 inches portrait? or should I say goodbye to 100 millions devices out there? I know it's a tough question and almost an opinion poll, but technically speaking I would like to find my best way

I'm working with adaptive Layout on iOS 8 and I want to get exactly what the size classes are on viewDidLoad . Any ideas about that? As of iOS 8 UIViewController adopts the UITraitEnvironment protocol. This protocol declares a property named traitCollection which is of type UITraitCollection . You can therefor access the traitCollection property simply by using self.traitCollection UITraitCollection has two properties that you want to access named horizontalSizeClass and verticalSizeClass Accessing these properties return an NSInteger . The enum that defines the returned values is declared in
