は、私は次のようなポップアップレイアウトを実装しようとしている:これは余白とすべてとストーリーボードで正常に動作iOS UILabelのマージンが崩れているコードの制約がありますか?
。ストーリーボードでは、次のようになります。
しかし、私はコードで同じ制約を加えた場合、私はこの結果を得る:
ラベルは、水色の背景とビューがありますラベルは内側に濃い青色の背景があります。ポップアップの背景には、周囲に境界線があります。だから基本的にポップアップは子供にマッチしますが、子供の中のラベルは親と祖父母をオーバーフローさせますが、それは余白があるからです...私が余白を取り除くと、ボーダーに向かいます!
私は、コード内でまったく同じ制約を作成しようとしました。私は、自動調整の幅を含む代替提案のために非常にオープンです。ポップアップを作成するための
マイコード:子を作成するための
func showPopup(caller: UIView) {
closePopups()
// setup view
currentPopup = UIView()
self.view.addSubview(currentPopup)
currentPopup.backgroundColor = UIColorFromHex(Constants.Colors.white, alpha: 1)
// setup constraints
currentPopup.translatesAutoresizingMaskIntoConstraints = false
// top constraint
let topSideConstraint = NSLayoutConstraint(item: currentPopup, attribute: .Top, relatedBy: .Equal, toItem: intoWordsBar.view, attribute: .Bottom, multiplier: 1.0, constant: 0)
self.view.addConstraint(topSideConstraint)
// setup child elements
var children = [PopupChildButton]()
let childOne = createChild("writing_strategy_1", parent: currentPopup, aboveChild: nil, hasBorder: true, feature: FeatureManager.BarFeature.WriteReadLetterName)
children.append(childOne)
