Array Extension #1

extension Array {
    mutating func firstToLast(){
        let elm = self.removeFirst()
        self.append(elm)
    }
    mutating func lastToFirst(){
        let elm = self.removeLast()
        self.insert(elm, atIndex: 0)
    }
}

使用

var tmp1:[Int] = [0,1,2,3]
tmp1.firstToLast()
print(tmp1)
tmp1.lastToFirst()
print(tmp1)

出力結果

[1, 2, 3, 0]
[0, 1, 2, 3]

UIScrollViewのページ番号
・paging Enabledをチェックしておく。
・delegateを紐付けておく。

func scrollViewWillBeginDragging(scrollView: UIScrollView) {
    let page:Int = Int( round(scrollView.contentOffset.x / scrollView.frame.size.width) )
    print("------begin \(page)")//スクロール開始時ページ番号
}
func scrollViewDidEndDecelerating(scrollView: UIScrollView) {
    let page:Int = Int( scrollView.contentOffset.x / scrollView.frame.size.width )
    print("------end \(page)")//スクロール完了時ページ番号
}
func scrollViewWillEndDragging(scrollView: UIScrollView, withVelocity velocity: CGPoint, targetContentOffset: UnsafeMutablePointer<CGPoint>) {
    let to:Int = Int( targetContentOffset.memory.x / scrollView.frame.size.width )//スクロール完了時ページ番号
    print("\n------endDrag \(to)")
}

addTarget@Swift3

button.addTarget(self, action:#selector(UIMainScrollView.onTapButton(_:)), forControlEvents: UIControlEvents.TouchUpInside)

XCodeをアップデートしたらコミット出来ず、下記メッセージが出る。

Couldn’t communicate with a helper application.

下記をターミナルで実行したら直った。

xcrun git config --global user.email sample@mail.com
xcrun git config --global user.name samplename

singleton@Swift3

class クラス名 {
    class var sharedInstance :クラス名 {
        struct Static {
            static let instance = クラス名()
        }
        return Static.instance
    }
    var 変数名:Int=0
}

使用時

let v:クラス名 = クラス名.sharedInstance
