Custom Control Development set for iOS development series-custom status bar message prompt control development

In actual development, message prompts are common requirements. In order to personalize and have simple UI status bar prompts, it is a good solution, with many benefits, such as: Do not block the main UI, new ideas, the following is the implementation code.
The WHC_StatusBarMessage.h header file is as follows:
