In case you’re setting an opaque backgroundColor on any subviews of the cell inside (and along with) the contentView, the appears to be like when the cell turns into highlighted or chosen could also be affected. The most effective method to resolve any factors alongside along with your subviews is to ensure their backgroundColor is able to nil or clear, and their opaque property is pretend. However, if needed you might 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 very best view controller to true. Failure to take motion leads to delicate 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 routinely items that view controller’s definesPresentationContext property to true. In case you’re specializing in earlier variations of iOS, set this property sooner than your search controller turns into vigorous. (31338934)
  • The UIRefreshControl class not instantly modifies the contentInset of its scroll view. As an alternative, its adjustments to the content material materials inset shall be built-in into the scroll view’s adjustedContentInset. The one exception is when the scroll view’s contentInsetAdjustmentBehavior is able to UIScrollView.ContentInsetAdjustmentBehavior.not at all, whereby case the UIRefreshControl event will modify the contentInset instantly as a result of it did in earlier releases. (35866834)
  • Must you implement self-sizing cells in a UITableView by overriding sizeThatFits(_:) with out using Auto Format, the height you come is interpreted as the desired prime for the contentView of the cell, and UITableViewCell routinely gives any additional prime needed to allow room for the cell separator. Must you implement information self-sizing this trend, the cell’s contentView width is assured to be right so to use in information format calculations when sizeThatFits(_:) is called on the UITableViewCell. (39742612)
  • Trait environments, comparable to views and take into consideration controllers, now have their traitCollection property populated with traits all through initialization. These preliminary traits characterize a prediction of the final phrase traits that the trait setting will receive when it can get added to the hierarchy. Because of the traits which will be populated all through initialization are solely a prediction, they could differ from the traits which will be acquired as quickly as really inside the hierarchy. Subsequently, when doable it’s 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 suggests window returns a non-nil price — so that you don’t have to throw away any work achieved using the anticipated traits if the exact traits are utterly totally different. The right time to utilize the traitCollection is all through format, comparable to inside layoutSubviews(), viewWillLayoutSubviews(), or viewDidLayoutSubviews().
  • The traitCollectionDidChange(_:) method is simply 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 inside the trip spot hierarchy, when the preliminary predicted traits match the final phrase traits inside the hierarchy, traitCollectionDidChange(_:) will not be generally known as when the trait setting is added to the hierarchy. Because of traitCollectionDidChange(_:) is supposed to be an invalidation callback to tell you that a lot of traits modified, audit your present implementations of this method, along with the UIContentContainer method willTransition(to:with:), for areas the place you would possibly want been relying on it to set off preliminary setup. The right place to lazily perform work that makes use of the traitCollection is inside one in all many layoutSubviews methods talked about above, nevertheless understand that these format methods are generally known as any time format occurs so you need to positively steer clear of repeating work for those who needn’t. (46818941)
  • Now you’ll be able to enable debug logging to easily see when traitCollectionDidChange(_:) or willTransition(to:with:) is called by your self programs. Activate the logging by using the following launch argument: -UITraitCollectionChangeLoggingEnabled YES. You might want to rapidly disable the Principal Thread Checker whereas using this launch argument and dealing your app from Xcode to steer clear of extra log messages for unrelated programs. (47858564)
  • The UITableViewCell class’s contentView property is always laid out edge-to-edge with adjoining tools, every on the primary and the trailing side. This streamlines the format code so builders who want the right 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’s an adjunct on the trailing side or not. You must 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 shall be adjusted routinely based mostly totally on the tools seen inside the cell to match the system’s default spacing. (48214114)
  • Now you’ll be able to invoke a custom-made initializer from a creation block that’s handed through instantiateInitialViewController(creator:) or instantiateViewController(identifier:creator:). This makes it doable so to initialize view controllers with additional context and arguments, whereas benefiting from defining them in a storyboard through Interface Builder. A custom-made controller initializer ought to identify its great.init(coder:) method and cross the coder argument that it receives through the creation block. (48313869)

UIKit – Recognized Factors

  • Earlier to iOS 13, UITextField assumed that the frames of its leftView and rightView had been precisely 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 opposition to and dealing on iOS 13, add specific sizing constraints on the view, wrap it in a plain UIView, or subclass the view and implement systemLayoutSizeFitting(_:).
