Is it possible to have a “#pragma mark” hierarchy?

问题

I use #pragma mark - Description frequently to organize my methods in Xcode. However, I find that sometimes I need to categories and subcategories for my methods, like this:

• Public Methods

  • Helper Methods
    • aMethod
  • Other Type of Methods
    • anotherMethod

• Private Methods

  • Some Type of Method
    • aPrivateMethod

Is this possible?

回答1:

Simply only use the - before and after your main section to surround it in lines, exclude the dash for the subsections, and then the method names will show as always.

#pragma mark - Public Methods -
#pragma mark Helper Methods
- (void)aMethod{}
#pragma mark Other Type of Methods
- (void)anotherMethod{}

#pragma mark - Private Methods -
#pragma mark Some Type of Method
- (void)aPrivateMethod{}

You can use any of these combinations:

1. Hyphen before Description - Puts a separator above the description

#pragma mark - Description

2. Hyphen after Description - Puts a separator below the description

#pragma mark Description -

3. Hyphen before and after Description - Puts a separator above and below the description

#pragma mark - Description -

Also, if you just want separators and no descriptions, simply use #pragma mark or #pragma mark -.
