Uicontrolstate.Normal Is Unavailable

UIControlState.Normal is Unavailable

Swift 3 update:

It appears that Xcode 8/Swift 3 brought UIControlState.normal back:

public struct UIControlState : OptionSet {

    public init(rawValue: UInt)

    public static var normal: UIControlState { get }

    public static var highlighted: UIControlState { get } // used when UIControl isHighlighted is set

    public static var disabled: UIControlState { get }

    public static var selected: UIControlState { get } // flag usable by app (see below)

    @available(iOS 9.0, *)
    public static var focused: UIControlState { get } // Applicable only when the screen supports focus

    public static var application: UIControlState { get } // additional flags available for application use

    public static var reserved: UIControlState { get } // flags reserved for internal framework use
}

UIControlState.Normal has been renamed to UIControlState.normal and removed from the iOS SDK. For "Normal" options, use an empty array to construct an empty option set.

let btn = UIButton(frame: CGRect(x: 0, y: 0, width: 20, height: 20))

// Does not work
btn.setTitle("title", for: .Normal) // 'Normal' has been renamed to 'normal'
btn.setTitle("title", for: .normal) // 'normal' is unavailable: use [] to construct an empty option set

// Works
btn.setTitle("title", for: [])

setTitle(_ title: String?, for state: UIControlState) where is .Normal state?

Like any other option set:

button.setTitle("", for: [])

where [] stands for .normal (the value of .normal is 0).

Note that we can use multiple states in one call:

button.setTitle("", for: [.selected, .disabled])

That's why UIControlState has been changed into an option set.

Alertview when song is unavailable

Try

if( q.items.count < 1 )  {
    [self showAlert];
    return;
}

before

[self.player setQueueWithQuery: q]

Using NSUserDefaults with Xcode 8 and iOS 10

NSUserDefaults has been renamed to UserDefaults. standardUserDefaults() has been renamed to standard().

let defaults = UserDefaults.standard

This now works.
