For the UI of the writing work, whether it should be done with xib/storyboard, or using handwritten code to complete

• For complex, dynamically generated interfaces, it is recommended to use a hand-written interface.
• For buttons or UI controls that require a uniform style, it is recommended to use manual code to construct them. Convenient for subsequent modification and reuse.
• For UIView classes or Uiviewcontroller classes that need to have inheritance or composition relationships, it is recommended that you manually write the interface in code.
• For those simple, static, non-core functional interfaces, consider using Xib or storyboard to accomplish this.
