Tweak-Tutorial

How Do You Create a Tweak?

For the Root.plist file, you can find out what cells are available to use by default here and here.

EXMRootListController.m

#import "EXMRootListController.h"

@implementation EXMRootListController

- (NSArray *)specifiers {
    if (!_specifiers) {
        _specifiers = [self loadSpecifiersFromPlistName:@"Root" target:self];
    }

    return _specifiers;
}

@end

This is the code of the view controller that displays when the user opens up the tweak settings page.

Let’s go through it one by one.

• It is importing the EXMRootListController.h header which contains the headers for this view controller.
• @implementation
  • This implements the view controller, basically allowing the developer to add methods and write the code for the view controller.
• - (NSArray *)specifiers {
  • This is the method holding all of the specifiers, i.e. the cells in the view controller.
• _specifiers = [self loadSpecifiersFromPlistName:@"Root" target:self];
  • This line sets _specifiers to the specifiers which are in the Root.plist.
• return _specifiers;
  • This returns the specifiers because that is needed as the method is not of the type void (which does not need to return anything).

This also allows the developer to make cells manually, you would need to add the specifier manually through PSSpecifier and then add it to the _specifiers array.

• Further information about this can be found near the bottom of https://theapplewiki.com/wiki/Dev:Preferences_specifier_plist.

Linking the preference bundle to the tweak can also be found in my preference bundle examples page: https://github.com/NightwindDev/Preference-Bundle-Example#linking-cells-to-tweak.
