iOS development-Simple skin-changing implementation and tool-type extraction

According to the pictures provided by the artist, there are two kinds of skin-changing schemes.

<1> artwork provides a picture of type one:

<2> Art provides the type of picture two: This kind of folder file name is the same situation, dragged into the project after the last use of the Real folder (blue folder). Because the yellow folder in the project does not exist, files with the same name will only retain one

Tick the second one:

Two. Extraction of tools--based on the scheme of the second picture, the extracted tool class

• Implementation of the header file
• Implementation of the. m file

• Note: The control text color or label background color, is defined in each color folder plist file, the file specifies the RGB
• When the outside calls the tool class, the error is prone (the project appears in the Tabbar controller case)-because the Tabbar controller's view is lazy loading, if the set skin class code is written in Viewdidload, the default will only be executed once;!!!!!! Solution: Write code in Viewwillappear

The plot of the error appears:
