basic software
First of all, we should learn Photoshop and Illustrator, which are the key software used in UI work. UI designers should master at least one or two kinds of design software, and other software can be mastered quickly as long as they touch the basics.
Visual design
Visual basics: learn the basics of art, composition design, color composition, layout design, icon design and so on.
Mobile terminal design
In the design of mobile terminals, iOS, Android, WP and Windows all have their own design rules. The resolution, status bar height, icon size, font and color of different models are strictly regulated on mobile terminals, and most models can change fonts. Mobile phone design specification, mobile phone user experience and interactive prototype design, icon design, space and detail design, interface design and so on should be studied.
Absolute code
UI designers need to learn some basic codes of WEB front-end, depending on the nature of work in actual work. Some UI designers need to use the knowledge of Web front-end when doing WEB design, but some other UI designs may not be used much, but it is also suggested that beginners may not be able to use this part completely, but you will definitely have docking work with WEB front-end development engineers, get to know each other and communicate with you.
The above is what UI designers need to learn.
