Sometimes we need to open Setting's Preferences not of our app, but of the iPhone itself. What should we do to acomplish this?
**[UPDATE: Added Wallet And Apple Pay below]**
**[UPDATE: Changed prefs for Bluetooth]**

1. You must configure the URL Schemes in your project. You will find it in Target, Info, URL Scheme. Once there, just type **prefs**

2.- Later, just write the code with the URL path of the preference needed. In my case was the keyboard path.
##Swift
UIApplication.sharedApplication().openURL(NSURL(string:"prefs:root=General&path=Keyboard")!)
##Objective-c
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"prefs:root=General&path=Keyboard"]];
