夜间模式的集成
You can call nightFalling or dawnComing to switch current theme version to DKThemeVersionNight or DKThemeVersionNormal.
[self.dk_manager dawnComing];
[self.dk_manager nightFalling];
Modify themeVersion property to directly switch theme version.
self.dk_manager.themeVersion = DKThemeVersionNormal;
self.dk_manager.themeVersion = DKThemeVersionNight;
// if there is a RED column in DKColorTable.txt (default) or in
// other `file` if you customize `file` property for `DKColorTable`
self.dk_manager.themeVersion = @"RED";
Post Notification
Every time the current theme version changes, DKNightVersionManager will post a DKNightVersionThemeChangingNotification. If you wanna to do some customization, you can observe this notification and react with proper actions.
