It is possible to hide the Status Bar, but think twice before doing so. For example, users might be interested in knowing if they are connected to a WiFi network when the app regularly downloads web content or if Bluetooth is enabled when the app requires a Bluetooth link to third-party hardware. A valid reason to hide the Status Bar is when you want to remove all distractions from a single element, for example, when displaying full screen content such as an image gallery.

The navigation bar contains the controls for navigating through the applications views and optionally to manage the content of the current view. It will always appear at the top of the screen, right below the status bar. By default, the background is slightly translucent and blurs content underneath the bar. The background fill of the bar can be set to a solid color, a gradient or a custom bitmap-pattern.

Similarly to the navigation bar, the background fill of toolbars can be modified, is translucent and blurs the underlaying content by default. Toolbars should be used when a specific view requires more than three primary actions that would hardly fit or would look messy in the navigation bar. Search bars come in two different styles by default: prominent and minimal. Both versions do have the same functionality. Search bars can make use of a prompt — a short sentence to introduce the functionality in the context of the search. To provide even more control over a search query, it is possible to chain the search Bar with a scope bar.

Table views are used to display small to large amounts of list style information in a single or multiple columns and with the option to divide several rows into separate sections or to group them. There are two basic table view types that should be used, depending on the type of data you are presenting.

A plain table contains a number of rows that can have a header on the top and a footer after the last row. A grouped table allows you to organize rows in groups. Each group can have a header best used to describe the context for the group as well as a footer good for help text, etc. A grouped table needs to contain at least one group, and each group needs to contain at least one row. For both table view types, a few styles are available to present the data in a way that allows users to easily scan, read and probably modify it.

The subtitle table style enables a small subtitle text underneath the row title. If a target is not using asset catalogs to manage its icons, each of the entries under the CFBundleIcons key in the information property must reference at least one image in the app bundle. Remember that if you include filename extensions in the information property list, you must specify the names of all icon image files including the high-resolution variants explicitly.

All icon images must be in PNG format and use a supported color model. Images that do not use the RGB color model may appear correctly in Xcode but will fail to load on the device. You can use the Preview application to inspect the format, color model, and size of an image.
