Ios 在UILabel中，多个字符串，每个字符串具有多种颜色？

在我的UILabel中，我想放置3个具有3种不同颜色的字符串每个字符串有一种特定的颜色

但我不想使用NSRange（计算字符数）。我会找到一个改变整个字符串颜色的解决方案，无论长度如何

例如：假设第一个字符串为蓝色，第二个字符串为绿色，第三个字符串为红色

var firstString: [String] = "hello how"
var secondString: [String] = "are you"
var thirdString: [String] = "buddy?"

myLabel.text = "\(firstString) \(secondString) \(thirdString)"

使用此输出：

这是一个NSMutableAttributedString，您必须弄清楚如何使用这些字符串，但是，无论您将此字符串用于什么，您都最希望从超类标题中公开一些内容，该标题公开AttributedText属性，您可以在其中为该属性指定“myString1”的值然后，您将不会为“text”属性提供值

var myString1 = NSMutableAttributedString(string:"hello how are you buddy")


let myString1Font1 = UIFont(name:"AvenirNext-Regular", size:24.0)


let myString1Color1 = UIColor(red: 0.292745, green: 0.461693, blue: 0.998524, alpha: 1.000000)
let myString1Color2 = UIColor(red: 0.000000, green: 0.176471, blue: 0.600000, alpha: 1.000000)
let myString1Color3 = UIColor(red: 0.333333, green: 0.556863, blue: 0.156863, alpha: 1.000000)
let myString1Color4 = UIColor(red: 0.643137, green: 0.031373, blue: 0.000000, alpha: 1.000000)


var myString1ParaStyle1 = NSMutableParagraphStyle()
myString1ParaStyle1.alignment = NSTextAlignment.Center



myString1.addAttribute(NSParagraphStyleAttributeName, value:myString1ParaStyle1, range:NSMakeRange(0,9))
myString1.addAttribute(NSUnderlineColorAttributeName, value:myString1Color1, range:NSMakeRange(0,9))
myString1.addAttribute(NSFontAttributeName, value:myString1Font1!, range:NSMakeRange(0,9))
myString1.addAttribute(NSForegroundColorAttributeName, value:myString1Color2, range:NSMakeRange(0,9))
myString1.addAttribute(NSParagraphStyleAttributeName, value:myString1ParaStyle1, range:NSMakeRange(9,8))
myString1.addAttribute(NSUnderlineColorAttributeName, value:myString1Color1, range:NSMakeRange(9,8))
myString1.addAttribute(NSFontAttributeName, value:myString1Font1!, range:NSMakeRange(9,8))
myString1.addAttribute(NSForegroundColorAttributeName, value:myString1Color3, range:NSMakeRange(9,8))
myString1.addAttribute(NSUnderlineColorAttributeName, value:myString1Color1, range:NSMakeRange(17,1))
myString1.addAttribute(NSParagraphStyleAttributeName, value:myString1ParaStyle1, range:NSMakeRange(17,1))
myString1.addAttribute(NSFontAttributeName, value:myString1Font1!, range:NSMakeRange(17,1))
myString1.addAttribute(NSParagraphStyleAttributeName, value:myString1ParaStyle1, range:NSMakeRange(18,5))
myString1.addAttribute(NSUnderlineColorAttributeName, value:myString1Color1, range:NSMakeRange(18,5))
myString1.addAttribute(NSFontAttributeName, value:myString1Font1!, range:NSMakeRange(18,5))
myString1.addAttribute(NSForegroundColorAttributeName, value:myString1Color4, range:NSMakeRange(18,5))

更好的答案，不必像我之前的答案那样添加下划线，并且自然对齐：

var myString1 = NSMutableAttributedString(string:"hello how are you buddy")

let myString1Font1 = UIFont(name:"Helvetica", size:14.0)

let myString1Color1 = UIColor(red: 0.000000, green: 0.176471, blue: 0.600000, alpha: 1.000000)
let myString1Color2 = UIColor(red: 0.247059, green: 0.411765, blue: 0.117647, alpha: 1.000000)
let myString1Color3 = UIColor(red: 0.607843, green: 0.172549, blue: 0.003922, alpha: 1.000000)

var myString1ParaStyle1 = NSMutableParagraphStyle()
myString1ParaStyle1.alignment = NSTextAlignment.Natural


myString1.addAttribute(NSForegroundColorAttributeName, value:myString1Color1, range:NSMakeRange(0,9))
myString1.addAttribute(NSParagraphStyleAttributeName, value:myString1ParaStyle1, range:NSMakeRange(0,9))
myString1.addAttribute(NSFontAttributeName, value:myString1Font1!, range:NSMakeRange(0,9))
myString1.addAttribute(NSFontAttributeName, value:myString1Font1!, range:NSMakeRange(9,1))
myString1.addAttribute(NSParagraphStyleAttributeName, value:myString1ParaStyle1, range:NSMakeRange(9,1))
myString1.addAttribute(NSForegroundColorAttributeName, value:myString1Color2, range:NSMakeRange(10,7))
myString1.addAttribute(NSParagraphStyleAttributeName, value:myString1ParaStyle1, range:NSMakeRange(10,7))
myString1.addAttribute(NSFontAttributeName, value:myString1Font1!, range:NSMakeRange(10,7))
myString1.addAttribute(NSFontAttributeName, value:myString1Font1!, range:NSMakeRange(17,1))
myString1.addAttribute(NSParagraphStyleAttributeName, value:myString1ParaStyle1, range:NSMakeRange(17,1))
myString1.addAttribute(NSForegroundColorAttributeName, value:myString1Color3, range:NSMakeRange(18,5))
myString1.addAttribute(NSParagraphStyleAttributeName, value:myString1ParaStyle1, range:NSMakeRange(18,5))
myString1.addAttribute(NSFontAttributeName, value:myString1Font1!, range:NSMakeRange(18,5))

哦，是的，我看到你想在UILabel中使用这个，UILabel有一个名为“AttributedText”的属性，你应该将这个属性设置为我为你创建的字符串，而不是设置“text”属性

这样做吗

myLabel.attributedText = myString1

此外，以下是简化的颜色：

let myString1Color1 = UIColor.blueColor()
let myString1Color2 = UIColor.greenColor()
let myString1Color3 = UIColor.redColor()

还有另一种方法：

var myString1 = NSMutableAttributedString(string:"hello how are you buddy?")

let myString1Font1 = UIFont(name:"Helvetica", size:14.0)

let myString1Color1 = UIColor.blueColor()
let myString1Color2 = UIColor.greenColor()
let myString1Color3 = UIColor.redColor()

let originalNSString = myString1.string as NSString
let myString1Range1 = originalNSString.rangeOfString("hello how ")
let myString1Range2 = originalNSString.rangeOfString("are you")
let myString1Range3 = originalNSString.rangeOfString(" ")
let myString1Range4 = originalNSString.rangeOfString("buddy?")

var myString1ParaStyle1 = NSMutableParagraphStyle()
myString1ParaStyle1.alignment = NSTextAlignment.Natural
myString1ParaStyle1.baseWritingDirection = NSWritingDirection.Natural
myString1ParaStyle1.defaultTabInterval = 0
myString1ParaStyle1.firstLineHeadIndent = 0
myString1ParaStyle1.headIndent = 0
myString1ParaStyle1.hyphenationFactor = 0
myString1ParaStyle1.lineBreakMode = NSLineBreakMode.ByWordWrapping
myString1ParaStyle1.lineHeightMultiple = 0
myString1ParaStyle1.lineSpacing = 0
myString1ParaStyle1.maximumLineHeight = 0
myString1ParaStyle1.minimumLineHeight = 0
myString1ParaStyle1.paragraphSpacing = 0
myString1ParaStyle1.paragraphSpacingBefore = 0
myString1ParaStyle1.tailIndent = 0

myString1.addAttribute(NSForegroundColorAttributeName, value:myString1Color1, range:myString1Range1)
myString1.addAttribute(NSParagraphStyleAttributeName, value:myString1ParaStyle1, range:myString1Range1)
myString1.addAttribute(NSFontAttributeName, value:myString1Font1!, range:myString1Range1)
myString1.addAttribute(NSForegroundColorAttributeName, value:myString1Color2, range:myString1Range2)
myString1.addAttribute(NSParagraphStyleAttributeName, value:myString1ParaStyle1, range:myString1Range2)
myString1.addAttribute(NSFontAttributeName, value:myString1Font1!, range:myString1Range2)
myString1.addAttribute(NSFontAttributeName, value:myString1Font1!, range:myString1Range3)
myString1.addAttribute(NSParagraphStyleAttributeName, value:myString1ParaStyle1, range:myString1Range3)
myString1.addAttribute(NSForegroundColorAttributeName, value:myString1Color3, range:myString1Range4)
myString1.addAttribute(NSParagraphStyleAttributeName, value:myString1ParaStyle1, range:myString1Range4)
myString1.addAttribute(NSFontAttributeName, value:myString1Font1!, range:myString1Range4)
