Extra argument green in call while using swift


How to accomplish this similar code with swift. However when I tried to accomplish with the swift, it is giving an error Extra argument green in call

+(UIColor *)colorWithValues:(NSString *)colorValues{
NSArray *colorComponents = [colorValues componentsSeparatedByString:@","];

CGFloat red = [[colorComponents objectAtIndex:0] floatValue]/255.0;
CGFloat green = [[colorComponents objectAtIndex:1] floatValue]/255.0;
CGFloat blue = [[colorComponents objectAtIndex:2] floatValue]/255.0;
CGFloat alpha = [[colorComponents objectAtIndex:3] floatValue];
UIColor *color = [[UIColor alloc]initWithRed:red 
                                       green:green 
                                        blue:blue 
                                       alpha:alpha];
//UIColor *color = [UIColor colorWithRed:red green:green blue:blue alpha:alpha];
return color;
}

bgView.backgoroundColor = [[self class]colorWithValues:@"155,124,144,1"];

    func colorWithValues(#colorToString : String) -> (UIColor) {

    var colorString = colorToString.componentsSeparatedByString(",")
    let redColor : Float = Float(colorString[0].toInt()!)/255.0
    let greenColor : Float = Float(colorString[1].toInt()!)/255.0
    let blueColor: Float = Float(colorString[2].toInt()!)/255.0
    let colorAlpha: Float = Float(colorString[3].toInt()!)

    var colorValue : UIColor! = UIColor(red:CGFloat(redColor), green:CGFloat(greenColor), blue:CGFloat(blueColor), alpha: colorAlpha)
    return colorValue
}

Solution

  • As I can see you forgot to wrap alpha in CGFloat

    var colorValue : UIColor! = UIColor(red:CGFloat(redColor), green:CGFloat(greenColor), 
    blue:CGFloat(blueColor), alpha: colorAlpha)
                                    ^^^^^^^^^^ here
    

    Which causes the problem, change it to this

    var colorValue : UIColor! = UIColor(red: CGFloat(redColor), green: CGFloat(greenColor), 
    blue: CGFloat(blueColor), alpha: CGFloat(colorAlpha))
