When you’re setting an opaque backgroundColor on any subviews of the cell inside (and along with) the contentView, the appears when the cell turns into highlighted or chosen is more likely to be affected. The most effective method to resolve any factors alongside together with your subviews is to verify their backgroundColor is about to nil or clear, and their opaque property is pretend. Nonetheless, if needed you can override the setHighlighted(_:animated:) and setSelected(_:animated:) methods to manually change these properties in your subviews when shifting to or from the highlighted and chosen states. (13955336)
  • Since iOS eight, using UISearchController with UINavigationController has required setting the definesPresentationContext property of the best view controller to true. Failure to take motion ends in refined bugs which may be onerous to detect and debug. Starting in iOS & iPadOS 13 beta, if a view controller’s navigationItem has a non-nil searchController, when the view controller is confirmed in a navigation controller, UINavigationController robotically models that view controller’s definesPresentationContext property to true. When you’re specializing in earlier variations of iOS, set this property sooner than your search controller turns into energetic. (31338934)
  • The UIRefreshControl class not straight modifies the contentInset of its scroll view.

(35866834)
  • In case you implement self-sizing cells in a UITableView by overriding sizeThatFits(_:) with out using Auto Construction, the height you come again is interpreted as the desired peak for the contentView of the cell, and UITableViewCell robotically supplies any additional peak needed to allow room for the cell separator. In case you implement information self-sizing this fashion, the cell’s contentView width is assured to be appropriate with the intention to use in information format calculations when sizeThatFits(_:) is known as on the UITableViewCell. (39742612)
  • Trait environments, equivalent to views and look at controllers, now have their traitCollection property populated with traits all through initialization. These preliminary traits signify a prediction of the final phrase traits that the trait ambiance will acquire when it can get added to the hierarchy. On account of the traits which will be populated all through initialization are solely a prediction, they might differ from the traits which will be obtained as quickly as really throughout the hierarchy. Subsequently, when doable it is best to attend to hold out work that makes use of the traitCollection until the view, or view controller’s view, has moved into the hierarchy — which means window returns a non-nil price — so that you should not have to throw away any work accomplished using the anticipated traits if the exact traits are utterly completely different. The easiest time to utilize the traitCollection is all through format, equivalent to inside layoutSubviews(), viewWillLayoutSubviews(), or viewDidLayoutSubviews().
  • The traitCollectionDidChange(_:) methodology is barely generally known as when the value of a trait modifications. Importantly, because of the trait assortment is now initialized to a prediction of the final phrase traits throughout the trip spot hierarchy, when the preliminary predicted traits match the final phrase traits throughout the hierarchy, traitCollectionDidChange(_:) will not be generally known as when the trait ambiance is added to the hierarchy. On account of traitCollectionDidChange(_:) is supposed to be an invalidation callback to tell you that quite a lot of traits modified, audit your current implementations of this technique, along with the UIContentContainer methodology willTransition(to:with:), for places the place you would possibly want been relying on it to set off preliminary setup. The easiest place to lazily perform work that makes use of the traitCollection is inside certainly one of many layoutSubviews methods talked about above, nevertheless take into account that these format methods are generally known as any time format occurs so make sure you stay away from repeating work everytime you needn’t. (46818941)
  • Now you may enable debug logging to easily see when traitCollectionDidChange(_:) or willTransition(to:with:) is known as by your self classes. Activate the logging by using the subsequent launch argument: -UITraitCollectionChangeLoggingEnabled YES. You may want to shortly disable the Major Thread Checker whereas using this launch argument and dealing your app from Xcode to stay away from further log messages for unrelated classes. (47858564)
  • The UITableViewCell class’s contentView property is always laid out edge-to-edge with adjoining tools, every on the principle and the trailing side. This streamlines the format code so builders who want the correct default offset not ought to align their content material materials with the content material materials view border or the format margin counting on whether or not or not there could also be an adjunct on the trailing side or not. You could now always lay out their code on the format margins of the cell’s content material materials view to get the default system insets. These insets will be adjusted robotically based on the tools seen throughout the cell to match the system’s default spacing. (48214114)
  • Now you may invoke a personalized initializer from a creation block that’s handed by means of instantiateInitialViewController(creator:) or instantiateViewController(identifier:creator:). This makes it doable with the intention to initialize view controllers with additional context and arguments, whereas benefiting from defining them in a storyboard by means of Interface Builder. A personalized controller initializer ought to title its large.init(coder:) methodology and transfer the coder argument that it receives by means of the creation block. (48313869)

UIKit – Recognized Factors

  • Earlier to iOS 13, UITextField assumed that the frames of its leftView and rightView have been appropriately set when assigned and would not at all change. Starting in iOS 13, the implementation of leftViewRect(forBounds:) and rightViewRect(forBounds:) now ask the view for its systemLayoutSizeFitting(_:). To achieve the sooner conduct when linking in direction of and dealing on iOS 13, add particular sizing constraints on the view, wrap it in a plain UIView, or subclass the view and implement systemLayoutSizeFitting(_:).
