UI Guidelines

Best practice

•

Use terms that identify the state of the option, and not the action required to change the state. For example, "On"

indicates the current state, while "Turn on" describes an action.

Text fields

If users need to type in your application, you can include text input fields. You can place the cursor in an editable text field.

Users can reposition the cursor by tapping another text field.

Keyboards

A virtual keyboard appears on the screen when users tap a text field. Users can hide the keyboard by touching the screen

outside the text field or by tapping the Hide Keyboard icon on the keyboard.

You can display a specific type of virtual keyboard, depending on the type of input that is required. In addition to the default

keyboard, you can choose from a selection of keyboards, such as a keyboard designed for typing in an email or a keyboard

designed for typing in a browser. For example, if users need to type an address for a website, you can display the URL

keyboard, which includes a .com button that lets users type the URL for a website more quickly. For each text field in your

application, make sure that the most appropriate keyboard appears when users touch the field.

In a form, users can press the Enter key to move the cursor to the next text field or UI component (for example, a Submit

button). This approach makes it easier for users to complete the form. In specific instances, you might consider changing

the label of the Enter key. For example, at the end of a form, you could change the label from Enter to Submit.
