Features of successful apps on Apple iOS platform (1)

Currently, the iOS platform mainly refers to the iPod Touch, iPhone, and iPad models. Recently, I started to study the related chapters of the iOS Human Interface Guide (HIG, I found that there are many questions that are frequently asked at the Getting Started level. In fact, I can answer them here. I would like to share some of the questions that many people may have on the experience and work with the above HIG document.

As described at the beginning of Platform Characteristics, successful applications embrace these features and integrate them between operating devices, therefore, familiarity with the Platform features on iOS, reasonable design and application of the platform in your own applications will be of great help to users in operating applications.

Everything on the screen

The operations on the iOS platform are almost always performed on the screen. The following three points can be applied to iOS platforms:

◆ The most comfortable click area is 44x44 Points rather than Pixels)

◆ The image design impact of applications is obvious.

◆ Users focus on content

The following are common iOS device screen sizes:

Device display direction

Basically, the principle is how the Home Screen displays the default display direction of the application.

◆ Because the Home Screen of the iPhone and iPod Touch is displayed in only one direction, it should be upright when it enters the application by default.

◆ On the iPad, because the main screen can be in the full direction, the direction of the application is expected to be consistent.
