As an app designer, you have the opportunity to deliver an extraordinary product that rises to the top of the App Store charts. To do so. Designing for iPhone Get in-depth information and UI resources for designing great apps that integrate seamlessly Read the Human Interface Guidelines.
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. Consistency A consistent app implements familiar standards and paradigms by using system-provided interface elements, well-known icons, standard text styles, and uniform terminology. Popovers are useful when a specific action requires multiple user inputs before proceeding. Points are a resolution-independent measurement. A consistent app implements familiar standards and paradigms by using system-provided interface elements, well-known icons, standard text styles, and uniform terminology. An alert view does always contain a title text, which should not be longer than one line and one for pure informational alerts, e. About these guidelines These guidelines describe how to design apps that follow the official HIG for iOS by Apple, not what you can do with custom controls.
Through direct manipulation, they can see the immediate, visible results of their actions. Feedback acknowledges actions and shows results to keep people informed. The built-in iOS apps provide perceptible feedback in response to every user action. Interactive elements are highlighted briefly when tapped, progress indicators communicate the status of long-running operations, and animation and sound help clarify the results of actions.
Metaphors work well in iOS because people physically interact with the screen. They move views out of the way to expose content beneath. They drag and swipe content. They toggle switches, move sliders, and scroll through picker values.
They even flick through pages of books and magazines. Throughout iOS, people—not apps—are in control. The best apps find the correct balance between enabling users and avoiding unwanted outcomes.

With the release of iOS 11, Apple introduced a new navigation bar style: Navigation Bar on iPhone in landscape mode. The height of the bar is reduced by 12pt, except on iPads. It's also a common practice to hide the status bar in landscape mode.
With the release of iOS 12, Apple increased the height of the base navigation bar by 6 points on iPad devices only.
Large titles continue to add a further 52 points to the height of the navigation bar.
A toolbar contains a set of actions for managing or manipulating the content of the current view. On the iPhone, it will always appear aligned at the bottom edge of the screen, while on the iPad, it can also be displayed aligned at the top of the screen. 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: 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.
The scope bar will use the same style as the search bar and might be useful when there are clearly defined categories for the search results. For example, in a music app, the search results could be filtered again by interpreters, albums or songs.
The tab bar is used to allow the user to quickly navigate through the separate views of an application, and it should only be used for this purpose. It always appears at the bottom edge of the screen.
By default, its slightly translucent and uses the same system blur for underlaying content as the navigation bar. A tab bar can only contain a fixed maximum number of tabs. To notify users about new information on a view, it sometimes makes sense to apply a badge count to a tab bar button. If a view is temporarily disabled, the related tab button should not be completely hidden; instead, it should be faded out to visually communicate the disabled state.
On the iPad, labels for tabs are rendered in a larger font size and next to the icon instead of below. Since iOS 12, the tab bar is also slightly taller, matching the increased height of toolbars 50pt. Tab Bar on the iPad Pro. Another 15pt of empty space are added below the tab bar for the virtual home button on iPads with liquid retina display.
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. It is useful for further explanations or short descriptions. The value table style allows you to display a specific value that is related to the row title.
Similar to the default style, each row can have an image and a title that are both aligned to the left. The title is followed by the right aligned label for the value, which is usually displayed in a slightly more subtle text color than the title. When displaying subtitles in a table view you should consider using the larger table cell style. While each temporary view exists for a very specific purpose and each one looks different, all temporary views still have one thing in common: An activity view is used to perform specific tasks.
These tasks can be default system tasks such as share content via the available options, or they can be completely custom actions. When designing icons for custom task buttons, you should follow the same guidelines as for the active state of bar button icons — solid fill, no effects, on a transparent background. Action Sheets are used to perform one single action from a list of available actions and to force the user of an app to confirm an action or cancel it.
In portrait mode and on small landscape screen resolutions , actions are always displayed as a list of buttons sliding in and staying at the bottom edge of the screen. In this case, an action sheet should always have a cancel button to close the view and not perform any of the listed actions.
When there is enough space available e.
A button to close the view is not required anymore because tapping a target anywhere outside the popover will close it automatically. The purpose of alerts is to inform the user about critical information and optionally to force the user to make a decision about some action.
An alert view does always contain a title text, which should not be longer than one line and one for pure informational alerts, e. Also, you can add a message text, if needed, as well as up to two text input fields, one of which can be a masked input field, which is appropriate for sensitive information like passwords or PINs.
While it is possible to control which operations the user can choose from, the visual appearance of edit menus is set and not configurable unless you build your own completely custom edit menu.
Popovers are useful when a specific action requires multiple user inputs before proceeding. A good example is adding an item, which has a few attributes that need to be set before the item can be created. In a horizontal environment, popovers reveal underneath the related control such as a button with an arrow pointing to that control while opened. The background of a popover uses a slightly reduced opacity and blurs the content underneath, just as many other UI elements have done since iOS 7.
A popover is a powerful temporary view that can contain various objects such as its own navigation bar, table views, maps or web views. When a popover grows in size due to the number of contained elements and reaches the bottom edge of the viewport, it is possible to scroll within the popover.
Modals are a useful view for tasks that require multiple commands or inputs by the user. They appear on top of everything else, and, while open, block interaction with any other interactive elements underneath.
Listed below you will find the most important commonly used , but for a full list of the available controls, you should look at the iOS Developer Library. Probably the most used control overall is the good old button. Since iOS 7, the default button design hasn't really looked like a button anymore, but rather more like a plain text link. The button control is highly customizable and allows you to style everything from text style, drop shadows and color to an icon that is either prepended or centered if there is no text label, as well as fully custom backgrounds.
Keep in mind that a button can have several states, which should be communicated with visual language: Pickers are used to select one value from a list of available values. The web equivalent would be a select box which the picker control is also used for when touching a select in Safari.
An extended version of picker is the datepicker, which allows the user to scroll through a list of dates and times and select values for configurable day, month and time. Except for the background color, it is not possible to change the visual style or size same as keyboard of a picker control.
Most often, they appear at the bottom of the screens, where keyboards appear as well, but it is possible to use them in other positions.
A segment control contains a set of segments at least two that can be used for things like filtering content or to create tabs for clearly categorized content types. Each segment can contain a text label or an image icon , but never both. In addition, using a mixed set of segment types text and images in one segment control is not really recommended. The width of one segment changes automatically based on the number of segments two segments: The slider control allows the user to choose one specific value from a range of allowed values.
Since choosing a value works pretty smoothly and without any steps, sliders are recommended for selecting an estimated, but not exact, value.
