The object header provides a quick view of the most important or most frequently-used information about one instance of an object. It connects to the iOS status bar and the navigation bar via a seamless background, and is visually separated from the content area below. Because the object header provides the first glimpse of the object on the screen, the information it contains should be clear and concise.
The object header is comprised of several pieces of information about the object. The title is the only required piece in the object header.
An image helps the user visually identify the object.
B. Main Content
The main content provides key information about the object.
C. Additional Information
Additional information includes tags and two short strings of relevant text.
D. Header Chart
A chart allows the user to quickly understand relevant trend or status information. See next section for more guidance.
A description provides the user with more details about the object.
A status section displays the current status of the object.
The object header supports various layout options based on the kinds of information it will contain. In the absence of both a chart and a description section, the additional information section may be moved to the right.
A chart and a description may both be included in the absence of the additional information section.
If the object name and title are the only content present in the object header (apart from the image and attribute sections), they may extend farther to the right within the header.
The title should be concise, but it can wrap onto multiple lines if needed.
The subtitle complements the title and may be used for secondary information (for example, a product number).
Tags are usually system-generated and may be used to indicate categories, types, or statuses. They use a different visual representation than plain text, and function as independent bits of information. There can be a maximum of three tags displayed in the header; if more than three are required, the information should instead be placed in the content area.
The footnotes contain two short strings of text providing important information (such as location, date, and time details) that can be consumed quickly.
Description is a short paragraph containing details about the object. It should only be used when it provides the user with valuable information.
The status section may include up to two status labels. An icon indicator may be used to compliment a single status label.
Aligning Content in Object Cell and Object Header
When the user navigates from an object cell to an object floorplan, it will be helpful if the content remains consistent. A general recommendation is to align the title, subtitle, footnote, description, and status in both views.
Given the limited horizontal space in compact width, the chart and description sections may be placed on separate pages and a page control added to allow the user to navigate between pages by swiping.
Similar to regular width, if there is no additional information section, a description paragraph can instead be included. This section again should not be too detailed, and should be used only when it provides the user with valuable information.
The header chart displays simple chart data inside an object header. It gives at-a-glance information about the object, and it is supported in both compact and regular widths.
The header chart can include different combinations of the following elements. However, one of the analytical components (trend, KPI, or chart plot) must be used for this component.
A. Chart Title
B. Subtitle or Time Stamp Label
C. Trend Label and Icon
E. X-Axis Labels
Only the first and last x-axis labels can be displayed.
F. Chart Plot
The header chart container can be used for either the chart KPI or regular KPI components. For the chart KPI, only the small variation can be used. Only one KPI can be used in each chart header container.
The header chart can be read-only or it can allow for navigation to a full screen chart. When navigation is enabled, the chart title should appear in tint color. The entire chart container will be one touch target with a single tap interaction.
If navigation from the header chart is not enabled, it is recommended to provide a chart content table view cell version of the chart within the content area of the screen. This way, if text in the header chart is truncated, or if the chart displays values from a large data set, the user will still be able to view the chart information in greater detail.
