    Moin,

    folgende Constraints setze ich:

    Quellcode

    1. addConstraintsWithFormat(format: "H:|[v0]|", views: thumbnailImageView)
    2. addConstraintsWithFormat(format: "H:|-8-[v0(44)]|", views: userProfileImage)
    3. addConstraintsWithFormat(format: "V:|[v0]-8-[v1(44)]-30-|", views: thumbnailImageView, userProfileImage)
    4. addConstraint(NSLayoutConstraint(item: titleLabel, attribute: .top, relatedBy: .equal, toItem: thumbnailImageView, attribute: .bottom, multiplier: 1, constant: 8))
    5. addConstraint(NSLayoutConstraint(item: titleLabel, attribute: .left, relatedBy: .equal, toItem: userProfileImage, attribute: .right, multiplier: 1, constant: 8))
    6. addConstraint(NSLayoutConstraint(item: titleLabel, attribute: .right, relatedBy: .equal, toItem: thumbnailImageView, attribute: .right, multiplier: 1, constant: 0))
    7. addConstraint(NSLayoutConstraint(item: titleLabel, attribute: .height, relatedBy: .greaterThanOrEqual, toItem: self, attribute: .height, multiplier: 0, constant: 20))
    8. addConstraint(NSLayoutConstraint(item: subTitleLabel, attribute: .top, relatedBy: .equal, toItem: titleLabel, attribute: .bottom, multiplier: 1, constant: 0))
    9. addConstraint(NSLayoutConstraint(item: subTitleLabel, attribute: .left, relatedBy: .equal, toItem: userProfileImage, attribute: .right, multiplier: 1, constant: 8))
    10. addConstraint(NSLayoutConstraint(item: subTitleLabel, attribute: .right, relatedBy: .equal, toItem: thumbnailImageView, attribute: .right, multiplier: 1, constant: 0))

    Ich finde leider meine Fehler nicht. Die App selbst sieht auch gut aus, also scheint es ja irgendwie zu funktionieren. Die Meldungen würde ich aber schon gerne weg haben.

    Hat jemand vielelicht eine Idee??

  • Ach ja hier die Helper Funktion

    Quellcode

    1. extension UIViewController {
    2. func addConstraintsWithFormat(format: String, views: UIView...){
    3. var viewsDictionary = [String: UIView]()
    4. for(index, view) in views.enumerated() {
    5. let key = "v\(index)"
    6. view.translatesAutoresizingMaskIntoConstraints = false
    7. viewsDictionary[key] = view
    8. }
    9. self.view.addConstraints(NSLayoutConstraint.constraints(withVisualFormat: format, options: NSLayoutFormatOptions(), metrics: nil, views: viewsDictionary))
    10. }
    11. }
