10 design principles for iOS Application Development

1. Easy to operate

The Control Design of iOS applications should have a sleek profile and a stylized gradient for easy operation.

2. Clear structure and convenient navigation

Make full use of the iOS navigation bar. Arrange all navigation in a hierarchical format to display the current location of the application.

3. Subtle and clear user feedback

Use an animation to display the user's operation results. A typical example is that the application will shake when the user presses for a long time to enter the "reschedule mode.

4. Ensure coordination of appearance and functions

If it is a productivity application, you can add decoration in the background to coordinate with it, and focus on maximizing functional benefits. If it is a game application, you should make full use of full screen, create an immersive experience.

To ensure that the application looks good for its functions, Apple calls it "aesthetic integrity )".

5. Highlight the primary task

Do not add anything redundant on the screen. Try to be concise and highlight the primary functions. For example, Apple's note application only allows you to enter new note content, and the email application only allows you to read and write emails.

6. Provide a logical path

The back button and other labels are provided to help you understand the current position of the application and the functions of each screen. It is best to ensure that each screen has only one specific path, so that it can be as concise as possible and give users a sense of familiarity.

7. Use Basic Terms

Avoid complicated and uncommon terms and use easy-to-understand communication methods. For example, Apple's Wi-Fi network is a good example. They can use super technical terms, but they actually use some common basic terms.

8. Consider adding simulated reality Elements

Apple's voice memo app displays a microphone image, and the address book app looks like a real address book. The more realistic simulation elements added to an application, the faster the user can understand how to interact with the application.

9. Consider directionality

When using a device, iOS users sometimes prefer the horizontal mode and the vertical mode to ensure that the content of the device remains the main focus no matter which method the app rotates.

10. Make sure that the touch point is suitable for the fingertip size

The recommended touch target size for Apple is 44*44 pixels. The buttons in the Apple calculator are a good example.
