Swift覚書02 頻度低

Posted at

自分用の覚え書きです。
Swift1.x混ざってるかも。

背景を敷き詰める

let collectionViewBg:UIImage = UIImage(named: "bg.png")!
self.view.backgroundColor = UIColor(patternImage: collectionViewBg)

アニメーション基本構文

UIView.animateWithDuration(
    0.4,
    delay: 0.4,
    options: UIViewAnimationOptions.CurveEaseOut,
    animations: {
        //
    },
    completion:{
        (value: Bool) in

    }
)

UIViewのhitTest

 override func hitTest(point: CGPoint, withEvent event: UIEvent?) -> UIView? {

        let rv:UIView? = super.hitTest(point , withEvent: event)
        return rv == self ? nil : rv

    }

NSDate

NSDateFormatterマジ便利。 曜日をとる場合はカレンダークラスで。

NSDateから文字列

let dateFormatter = NSDateFormatter() // フォーマットの取得
dateFormatter.locale = NSLocale(localeIdentifier: "ja_JP")  // JPロケール
dateFormatter.dateFormat = "yyyy/MM/dd HH:mm:ss" // フォーマットの指定
print(dateFormatter.stringFromDate( NSDate() ) )

文字列からNSDate

var date_string: String = "2014-12-01 10:00:00"
var date_formatter: NSDateFormatter = NSDateFormatter()
date_formatter.locale     = NSLocale(localeIdentifier: "ja")
date_formatter.dateFormat = "yyyy/MM/dd HH:mm:ss"
date_formatter.dateFromString( date_string )
