On iOS 8 Apple gave us the possibility to go to the App Settings right from our app, using the Constant UIApplicationOpenSettingsURLString
UIApplication.sharedApplication().openURL(NSURL.URLWithString(UIApplicationOpenSettingsURLString))
There's a code to test if this Constant exists on iOS 7, but it uses ObjC and pointes. Apple did this on their code: https://developer.apple.com/library/ios/samplecode/AppPrefs/Listings/RootViewController_m.html
How can I make something like this using Swift?
In Swift:
switch UIDevice.currentDevice().systemVersion.compare("8.0.0", options: NSStringCompareOptions.NumericSearch) {
case .OrderedSame, .OrderedDescending:
UIApplication.sharedApplication().openURL(NSURL.URLWithString(UIApplicationOpenSettingsURLString))
case .OrderedAscending:
//Do Nothing.
}
In Objective-C:
if (&UIApplicationOpenSettingsURLString != NULL) {
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:UIApplicationOpenSettingsURLString]];
}
