swift / UIViewを左右に揺らす

       var transform:CGAffineTransform = CGAffineTransformIdentity
        let duration:Double = 0.5
        transform = CGAffineTransformMakeRotation(CGFloat(0.25*M_PI))
        UIView.animateWithDuration(duration,animations:{()-> Void in
            sender.transform = transform
            })
            { (Bool)-> Void in
             UIView.animateWithDuration(duration,animations:{ () -> Void in
                sender.transform = CGAffineTransformIdentity
                }){ (Bool) -> Void in
            }
        }

swift / 任意のsegueに移動

performSegueWithIdentifier("hoge", sender: nil)

swift / UIButtonをコードでグラデーションかけたり、角丸にしたり

import UIKit
import QuartzCore

...
        let gradient = CAGradientLayer();
        gradient.frame = button.bounds;
        let arryColors = [
            colorWithRGBHex(0xFFFFFF,alpha:1.0).CGColor as AnyObject,
            colorWithRGBHex(0xCCCCCC,alpha:1.0).CGColor as AnyObject
        ];
        gradient.colors = arryColors;
        button.layer.insertSublayer(gradient, atIndex:0)
        
        //ボタンを角丸に
        button.layer.masksToBounds = true;
        button.layer.cornerRadius = 5.0;
        button.setTitleColor(UIColor.blackColor(),forState: UIControlState.Normal);

swift / 画面縦横サイズを取得

let screenWidth:Double = Double(UIScreen.mainScreen().bounds.size.width)
let screenHeight:Double = Double(UIScreen.mainScreen().bounds.size.height)

swift / ColorコードをUIColorに変換

    func colorWithRGBHex(hex:Int,alpha: Float = 1.0) -> UIColor{
        let r = Float((hex >> 16) & 0xFF);
        let g = Float((hex >> 8) & 0xFF);
        let b = Float((hex ) & 0xFF);
        return UIColor(
            red: CGFloat(r / 255.0),
            green: CGFloat(g / 255.0),
            blue: CGFloat(b / 255.0),
            alpha: CGFloat(alpha))
    }

使い方

        let arryColors = [
            colorWithRGBHex(0xFFFFFF,alpha:1.0).CGColor as AnyObject,
            colorWithRGBHex(0xCCCCCC,alpha:1.0).CGColor as AnyObject
        ];

swift / loadCSV

    func loadCSV(filename: String) -> [String] {
        let csvBundle = NSBundle.mainBundle().pathForResource(filename, ofType: "csv");
        
        var csvArray:Array<String> = [];
        do {
            let csvData = try String(contentsOfFile: csvBundle!,
                encoding: NSUTF8StringEncoding)
            let lineChange = csvData.stringByReplacingOccurrencesOfString("\r", withString: "\n")
            csvArray = lineChange.componentsSeparatedByString("\n")
        }
        catch {
            print("csv load error")
        }
        return csvArray;
    }

swift / soundPlayerClass

import Foundation
import AVFoundation

class SEManager: NSObject,AVAudioPlayerDelegate{
    var soundArray = [AVAudioPlayer]()
    func sePlay(soundName: String ,loop: Bool){
        let url = NSBundle.mainBundle().bundleURL.URLByAppendingPathComponent(soundName)
        var player:AVAudioPlayer?
        do {
            try player = AVAudioPlayer(contentsOfURL: url)
        }catch{
            print("Error!")
        }
        if(loop){
            player?.numberOfLoops = -1;
        }
        soundArray.append(player!);
        player?.delegate = self;
        player?.prepareToPlay();
        player?.play();
    }
    func audioPlayerDidFinishPlaying(player: AVAudioPlayer, successfully flag: Bool) {
        let i:Int = soundArray.indexOf(player)!
        soundArray.removeAtIndex(i)
    }
}
