These labels appear in `Unable to simultaneously satisfy constraints` logs, making it easier to identify and debug specific layout issues, for example, showing "buttonViewTopConstraint" in the log output. ```Swift button.snp.makeConstraints { (make) -> Void in make.top.equalTo(otherView).labeled("buttonViewTopConstraint") } ``` -------------------------------- ### Integrate SnapKit with Carthage Cartfile Source: https://snapkit.github.io/SnapKit/docs/index Specifies SnapKit as a dependency in a Cartfile for Carthage, indicating the GitHub repository and version range for integration. ```text github "SnapKit/SnapKit" ~> 5.6 ``` -------------------------------- ### Set Width and Height Range with SnapKit Source: https://snapkit.github.io/SnapKit/docs/index Demonstrates how to set minimum and maximum width constraints using `greaterThanOrEqualTo` and `lessThanOrEqualTo` for constant values in SnapKit. ```Swift // width >= 200 && width <= 400 make.width.greaterThanOrEqualTo(200) make.width.lessThanOrEqualTo(400) ``` -------------------------------- ### Use Priority Shortcuts in SnapKit Source: https://snapkit.github.io/SnapKit/docs/index Illustrates the use of predefined priority shortcuts like `.low`, `.medium`, `.high`, `.required` for setting constraint priorities in SnapKit. ```Swift make.top.equalTo(label.snp.top).priority(.medium) ``` -------------------------------- ### Create Constraints with Primitives and Structs in SnapKit Source: https://snapkit.github.io/SnapKit/docs/index Shows various ways to define constraints using primitive values (integers) and UIKit structs like `CGSize` and `UIEdgeInsets` for `top`, `height`, `size`, `edges`, and `left` attributes. ```Swift make.top.equalTo(42) make.height.equalTo(20) make.size.equalTo(CGSize(width: 50, height: 100)) make.edges.equalTo(UIEdgeInsets(top: 10, left: 0, bottom: 10, right: 0)) make.left.equalTo(view).offset(UIEdgeInsets(top: 10, left: 0, bottom: 10, right: 0)) ``` -------------------------------- ### Specify Exact Constraint Priority in SnapKit Source: https://snapkit.github.io/SnapKit/docs/index Demonstrates how to set an exact priority value for a constraint using the `.priority()` method at the end of a constraint chain. ```Swift make.top.equalTo(label.snp.top).priority(600) ``` -------------------------------- ### Integrate SnapKit with CocoaPods Podfile Source: https://snapkit.github.io/SnapKit/docs/index Specifies SnapKit as a dependency in a Podfile for an Xcode project, targeting iOS 10.0 and using frameworks. Replace '' with your actual target. ```ruby source 'https://github.com/CocoaPods/Specs.git' platform :ios, '10.0' use_frameworks! target '' do pod 'SnapKit', '~> 5.6' end ``` -------------------------------- ### Chain View Attributes for Readability in SnapKit Source: https://snapkit.github.io/SnapKit/docs/index Shows how to chain multiple view attributes (e.g., `left.right.bottom`) to apply the same constraint to several edges, improving code readability. ```Swift // All edges but the top should equal those of the superview make.left.right.bottom.equalTo(superview) make.top.equalTo(otherView) ``` -------------------------------- ### Snap View to SafeAreaLayoutGuide with SnapKit (Swift) Source: https://snapkit.github.io/SnapKit/docs/index This snippet demonstrates how to use `safeAreaLayoutGuide` with SnapKit to correctly position views relative to the safe area, replacing the deprecated `topLayoutGuide` and `bottomLayoutGuide` in iOS 11+. It shows a `UITableView` being constrained to the top of the `safeAreaLayoutGuide` within a `UIViewController`. ```Swift import SnapKit class MyViewController: UIVewController { lazy var tableView = UITableView() override func viewDidLoad() { super.viewDidLoad() self.view.addSubview(tableView) tableView.snp.makeConstraints { (make) -> Void in make.top.equalTo(self.view.safeAreaLayoutGuide.snp.top) } } } ``` -------------------------------- ### SnapKit ViewAttribute to NSLayoutAttribute Mapping Source: https://snapkit.github.io/SnapKit/docs/index Documents the mapping between SnapKit's `ViewAttribute` properties (e.g., `view.snp.left`) and their corresponding `NSLayoutConstraint.Attribute` values in UIKit/AppKit for constraint definition. ```APIDOC | ViewAttribute | NSLayoutAttribute | | --- | --- | | view.snp.left | NSLayoutConstraint.Attribute.left | | view.snp.right | NSLayoutConstraint.Attribute.right | | view.snp.top | NSLayoutConstraint.Attribute.top | | view.snp.bottom | NSLayoutConstraint.Attribute.bottom | | view.snp.leading | NSLayoutConstraint.Attribute.leading | | view.snp.trailing | NSLayoutConstraint.Attribute.trailing | | view.snp.width | NSLayoutConstraint.Attribute.width | | view.snp.height | NSLayoutConstraint.Attribute.height | | view.snp.centerX | NSLayoutConstraint.Attribute.centerX | | view.snp.centerY | NSLayoutConstraint.Attribute.centerY | | view.snp.lastBaseline | NSLayoutConstraint.Attribute.lastBaseline | ``` -------------------------------- ### Update Constraints Using References in SnapKit Source: https://snapkit.github.io/SnapKit/docs/index Explains how to hold a reference to a particular constraint (or multiple constraints by storing them in an array) to later deactivate or update its offset, providing fine-grained control over individual constraints. ```Swift var topConstraint: Constraint? = nil ... // when making constraints view1.snp.makeConstraints { (make) -> Void in self.topConstraint = make.top.equalTo(superview).offset(padding.top).constraint make.left.equalTo(superview).offset(padding.left) } ... // then later you can call self.topConstraint.deactivate() // or if you want to update the constraint self.topConstraint.updateOffset(5) ``` -------------------------------- ### Constrain UIView to Superview Edges with Padding (Concise) Source: https://snapkit.github.io/SnapKit/docs/index Demonstrates a shorter way to use SnapKit's `edges` property to constrain a UIView to its superview's edges with 20 points of padding using `UIEdgeInsets`, improving readability. ```swift let box = UIView() superview.addSubview(box) box.snp.makeConstraints { (make) -> Void in make.edges.equalTo(superview).inset(UIEdgeInsets(top: 20, left: 20, bottom: 20, right: 20)) } ``` -------------------------------- ### Constrain UIView to Superview Edges with Padding (Verbose) Source: https://snapkit.github.io/SnapKit/docs/index Demonstrates how to use SnapKit to constrain a UIView to its superview's edges with 20 points of padding using individual top, left, bottom, and right constraints. ```swift let box = UIView() superview.addSubview(box) box.snp.makeConstraints { (make) -> Void in make.top.equalTo(superview).offset(20) make.left.equalTo(superview).offset(20) make.bottom.equalTo(superview).offset(-20) make.right.equalTo(superview).offset(-20) } ``` -------------------------------- ### Update Constraint Constants with snp.updateConstraints in SnapKit Source: https://snapkit.github.io/SnapKit/docs/index Demonstrates using `snp.updateConstraints` within `updateConstraints()` to modify only the constant values of existing constraints, which is Apple's recommended approach for updates and can be called multiple times in response to `setNeedsUpdateConstraints`. ```Swift // this is Apple's recommended place for adding/updating constraints // this method can get called multiple times in response to setNeedsUpdateConstraints // which can be called by UIKit internally or in your code if you need to trigger an update to your constraints override func updateConstraints() { self.growingButton.snp.updateConstraints { (make) -> Void in make.center.equalTo(self); make.width.equalTo(self.buttonSize.width).priority(250) make.height.equalTo(self.buttonSize.height).priority(250) make.width.lessThanOrEqualTo(self) make.height.lessThanOrEqualTo(self) } // according to Apple super should be called at end of method super.updateConstraints() } ``` -------------------------------- ### SnapKit Constraint with UIView/NSView Reference Source: https://snapkit.github.io/SnapKit/docs/index Illustrates how SnapKit allows directly referencing a `UIView` or `NSView` object in a constraint, which is equivalent to referencing its default `left` attribute for convenience. ```swift // these two constraints are exactly the same make.left.greaterThanOrEqualTo(label) make.left.greaterThanOrEqualTo(label.snp.left) ``` -------------------------------- ### Set Alignment Attributes Relative to Superview in SnapKit Source: https://snapkit.github.io/SnapKit/docs/index Illustrates how SnapKit handles alignment attributes (like `left`, `right`, `centerY`) when constant values are passed, automatically creating constraints relative to the superview. ```Swift // creates view.left <= view.superview.left + 10 make.left.lessThanOrEqualTo(10) ``` === COMPLETE CONTENT === This response contains all available snippets from this library.
