UIView Extension #6
func animateBG2Black(duration:CGFloat=0.3){
UIView.setAnimationBeginsFromCurrentState(true)
UIView.animateWithDuration(NSTimeInterval(duration), delay: 0.0, usingSpringWithDamping: 1.0, initialSpringVelocity: 0.0, options: UIViewAnimationOptions.CurveLinear,
animations: { () -> Void in
self.backgroundColor = UIColor.blackColor()
},
completion: { (finish:Bool) -> Void in
}
)
}
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)")
}

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

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
