问题 This is only an iOS 8 problem, the keyboard displays correctly in iOS 7 with device orientation change. My application supports both portrait and landscape orientation and uses autolayout. If I push a UIViewController subclass that contains a UITextField subclass onto a navigation stack and the UITextField becomes the first responder in portrait orientation then the default keyboard displays correctly.

I would like to request the Always permission only when user opts-in to my geofencing feature. But calling CLLocationManager.requestAlwaysAuthorization has no effect because the current authorization status is no longer kCLAuthorizationStatusNotDetermined. How would one go about requesting the Always permission AFTER user has granted When In Use permission? I would think this is a

问题 How do you count the amount of unique items in an Array? Example: let array:Array<Int> = [1,3,2,4,6,1,3,2] Count function: array.count will give 8 but I want to count unique items and this will give 5 回答1: You can use NSSet to throw away duplicates: let array:Array<Int> = [1,3,2,4,6,1,3,2] let count = NSSet(array: array).count println(count) This prints: 5 回答2: As of Swift 1.2 , Swift has a native Set type.
