iOS常用的全局定义(swift版)

//获取屏幕宽度与高度

let SCREEN_WIDTH = UIScreen.mainScreen().bounds.size.width

let SCREENH_HEIGHT = UIScreen.mainScreen().bounds.size.height

//获取通知中心

let YYNotificationCenter = NSNotificationCenter.defaultCenter

//设置clear背景颜色

let YYClearColor = UIColor.clearColor()

//设置view的圆角和边框

func YYViewBorderRadius(view: UIView, radius: CGFloat, CGFloat, color: UIColor) {

    view.layer.cornerRadius = radius

    view.layer.masksToBounds = true

    view.layer.borderWidth = width

    view.layer.borderColor = color.CGColor

}

//获取view的frame

func YYGetViewWidth(view: UIView) -> CGFloat {

    return view.frame.size.width

}

func YYGetViewHeight(view: UIView) -> CGFloat {

    return view.frame.size.height

}

func YYGetViewX(view: UIView) -> CGFloat {

    return view.frame.origin.x

}

func YYGetViewY(view: UIView) -> CGFloat {

    return view.frame.origin.y

}

//获取图片资源

func YYGetImage(imageName: String) -> UIImage? {

    return UIImage(named: imageName)

}

//获取当前语言

let YYCurrentLanguage = NSLocale.preferredLanguages().first!

//判断当前的设备

let IS_IPHONE: Bool = UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiom.Phone

let IS_IPAD: Bool = UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiom.Pad

let iPhone5SE: Bool = UIScreen.mainScreen().bounds.size.width == 320.0 && UIScreen.mainScreen().bounds.size.height == 568.0

let iPhone6_6s: Bool = UIScreen.mainScreen().bounds.size.width == 375.0 && UIScreen.mainScreen().bounds.size.height == 667.0

let iPhone6Plus_6sPlus: Bool = UIScreen.mainScreen().bounds.size.width == 414.0 && UIScreen.mainScreen().bounds.size.height == 736.0

//获取系统版本

let IOS_SYSTEM_VERSION: String = UIDevice.currentDevice().systemVersion

// dispath 工具方法

var GlobalMainQueue: dispatch_queue_t {

    return dispatch_get_main_queue()

}

func delay(seconds seconds: Double, completion:()->()) {

    let popTime = dispatch_time(DISPATCH_TIME_NOW, Int64( Double(NSEC_PER_SEC) * seconds ))

    dispatch_after(popTime, dispatch_get_main_queue()) {

        completion()

    }

}

//使用色值创建图片

func createImageWithColor(color: UIColor) -> UIImage {

        let rect = CGRectMake(0.0, 0.0, 1.0, 1.0)

        UIGraphicsBeginImageContext(rect.size);

        let context = UIGraphicsGetCurrentContext();

        CGContextSetFillColorWithColor(context, color.CGColor);

        CGContextFillRect(context, rect);

        let theImage = UIGraphicsGetImageFromCurrentImageContext();

        UIGraphicsEndImageContext();

        return theImage;
}
