nslayoutconstraint

I want to have several objects that I can drag and drop. Here's my code for moving one object (with lot of help from @vacawama): import UIKit class ViewController: UIViewController { @IBOutlet weak var panView: UIView! @IBOutlet weak var panViewCenterX: NSLayoutConstraint! @IBOutlet weak var panViewCenterY: NSLayoutConstraint! let panRec = UIPanGestureRecognizer() override func viewDidLoad() { super.viewDidLoad() panRec.addTarget(self, action: "draggedView:") panView.addGestureRecognizer(panRec) // Do any additional setup after loading the view, typically from a nib. } func draggedView(sender

Attaching the view i am planning to design. I would like to position the Buttons with respect to Superview and their Width and Height must increase proportionally to the Screen Size rather than remaining fixed. Attaching the screen preview: This is an example just for one row of your buttons, so they can be reused for other UI elements. Put these constraints onto your buttons: LEFT BUTTON: left leading constraint top leading constraint height constraint RIGHT BUTTON right trailing constraint top leading constraint height constraint And constraints related to both buttons: (you need to select

I have two label, L1 and L2 of variable and nonidentical length. I want to place these two label using constraints in Xcode. If possible i don't want to manipulate constraints programmatically. guidance will be appreciated. Right image should be the expected output Requirements, Two labels are non identical in width When running leading space of L1 and trailing space of L2 will be equal distance between L1 & L2, horizontal space is fixed, 10 px UIStackView cannot be used How can I do it from Xcode? What you can do is put both the UILabel inside a UIView and then: Add a leading, top and bottom

I have a viewController and I want to have two 1 tableView and 1 childViewController inside it. tableView is non-scrollable with dynamic cell heights. (I'm using a tableView so I can collapse rows) childVC is a scrollable tableView with dynamic cell heights. my constraints are as: NSLayoutConstraint.activate([ tableView.topAnchor.constraint(equalTo: view.topAnchor), tableView.trailingAnchor.constraint(equalTo: view.trailingAnchor), tableView.leadingAnchor.constraint(equalTo: view.leadingAnchor), tableView.bottomAnchor.constraint(equalTo: artistVC.view.topAnchor), ]) NSLayoutConstraint.activate

I created a demo project here . I have a view where I created a ScrollView in a .xib file. In interface builder I did not set any constraints. In my viewDidLoad method I set constraints with SnapKit : scrollView.snp_makeConstraints { (make) -> Void in make.edges.equalTo(self.view) } When I run the code I get the following console output: Unable to simultaneously satisfy constraints. Probably at least one of the constraints in the following list is one you don't want. Try this: (1) look at each constraint and try to figure out which you don't expect; (2) find the code that added the unwanted

I have a view controller laid out in a storyboard with autolayout enabled and am looking for a way to change constraints to allow for my view to rotate into landscape and rearrange buttons on the screen. When I try the code below, I get about two dozen "unable to satisfy constraints, breaking constraint..." messages that I cannot really decode. Is there a way to dynamically replace constraints from a storyboard with constraints that I specify programmatically? I want to completely override the layout of the buttons that I defined in a storyboard. -(void)updateViewConstraints { [super
