Is there a way to, from my code query the iOS settings app for a certain setting? For example I want to know if “Multitasking Gestures” is turned on or not? Or even be able to change the settings?(From my research it seems like I definitely cant do this)
No. In general, you can read your own app’s preferences (whether they’re set via the Settings app or by your app) using NSUserDefaults. You cannot, however, read the preferences for other applications, including system settings. There may be cases where you can figure out what the setting must be by using API specific to that setting, but in such cases you still shouldn’t assume that you know what selection the user has made in the Settings app.
