Developer documentation

How to programmatically enable/disable DarkModeToggle from another tweak:

1. Set dark or light for the darkModeState key in /var/mobile/Library/Preferences/com.captinc.darkmodetoggle.plist
2. Post this NSDistributedNotification: com.captinc.darkmodetoggle.updateState

How to programmatically detect when DarkModeToggle is toggled:

1. Listen for this NSDistributedNotification: com.captinc.darkmodetoggle.stateChanged

Note: because my tweak uses NSDistributedNotifications instead of NSNotifications, you can enable/disable/detect DarkModeToggle from any process

Code examples

Before starting, place this at the top of your code:

@interface NSDistributedNotificationCenter : NSNotificationCenter
@end

Enable DarkModeToggle:

NSString *plistPath = @"/var/mobile/Library/Preferences/com.captinc.darkmodetoggle.plist";
NSMutableDictionary *prefs = [NSMutableDictionary dictionaryWithContentsOfFile:plistPath];
if (!prefs) {
    prefs = [[NSMutableDictionary alloc] init];
}
[prefs setObject:@"dark" forKey:@"darkModeState"];
[prefs writeToFile:plistPath atomically:YES];
[[NSDistributedNotificationCenter defaultCenter] postNotificationName:@"com.captinc.darkmodetoggle.updateState" object:nil userInfo:nil];

Disable DarkModeToggle:

NSString *plistPath = @"/var/mobile/Library/Preferences/com.captinc.darkmodetoggle.plist";
NSMutableDictionary *prefs = [NSMutableDictionary dictionaryWithContentsOfFile:plistPath];
if (!prefs) {
    prefs = [[NSMutableDictionary alloc] init];
}
[prefs setObject:@"light" forKey:@"darkModeState"];
[prefs writeToFile:plistPath atomically:YES];
[[NSDistributedNotificationCenter defaultCenter] postNotificationName:@"com.captinc.darkmodetoggle.updateState" object:nil userInfo:nil];

Toggle DarkModeToggle to the opposite state:

NSString *plistPath = @"/var/mobile/Library/Preferences/com.captinc.darkmodetoggle.plist";
NSMutableDictionary *prefs = [NSMutableDictionary dictionaryWithContentsOfFile:plistPath];
if (!prefs) {
    prefs = [[NSMutableDictionary alloc] init];
}
NSString *currentState = [prefs objectForKey:@"darkModeState"];

if ([currentState isEqualToString:@"dark"]) {
    [prefs setObject:@"light" forKey:@"darkModeState"];
}
else if ([currentState isEqualToString:@"light"]) {
    [prefs setObject:@"dark" forKey:@"darkModeState"];
}
[prefs writeToFile:plistPath atomically:YES];
[[NSDistributedNotificationCenter defaultCenter] postNotificationName:@"com.captinc.darkmodetoggle.updateState" object:nil userInfo:nil];

Detect when DarkModeToggle is toggled:

- (void)oneOfYourMethods {
    [[NSDistributedNotificationCenter defaultCenter] addObserver:self selector:@selector(itWasToggled) name:@"com.captinc.darkmodetoggle.stateChanged" object:nil];
}
- (void)itWasToggled {
    doSomething();
}
