提问by Forte Zhu
I try to set UILabel with text of different colors programmatically using,
我尝试使用不同颜色的文本以编程方式设置 UILabel，
NSMutableAttributedString * string = [[NSMutableAttributedString alloc] initWithString:@"firstsecondthird"];
[string addAttribute:NSForegroundColorAttributeName value:[UIColor redColor] range:NSMakeRange(0,5)];
[string addAttribute:NSForegroundColorAttributeName value:[UIColor greenColor] range:NSMakeRange(5,6)];
[string addAttribute:NSForegroundColorAttributeName value:[UIColor blueColor] range:NSMakeRange(11,5)];
[self.resultLabel setAttributedText:string];
I get what I expected. But, I am interested in doing all these stuff in storyboard,in main.storyboard. Can anyone help me in doing this.

To achieve that in storyboard, make the label's text attributed, then select the range and change colors accordingly.
要在 中实现这一点storyboard，请对label的文本进行属性化，然后选择范围并相应地更改颜色。

Using storyboard interface:
使用故事板界面：
with Swift 3 & 4:
Programatically you can set label colors very easily.
使用 Swift 3 & 4：
您可以很容易地以编程方式设置标签颜色。
extension NSMutableAttributedString {
func setColorForText(textToFind: String, withColor color: UIColor) {
let range: NSRange = self.mutableString.range(of: textToFind, options: .caseInsensitive)
if range != nil {
self.addAttribute(NSAttributedStringKey.foregroundColor, value: color, range: range)
}
}
}
func setColoredLabel() {
var string: NSMutableAttributedString = NSMutableAttributedString(string: "My label with red blue and green colored text")
string.setColorForText(textToFind: "red", withColor: UIColor.red)
string.setColorForText(textToFind: "blue", withColor: UIColor.blue)
string.setColorForText(textToFind: "green", withColor: UIColor.green)
yourLabel.attributedText = string
}
Result:

If I am understanding your question correctly, then in storyboard most of the options have little plus buttons beside them so that you can customize the labels and attributes. Make sure that you are not using plain text but rather attributed text it is the first dropdown choice in the column.
如果我正确理解了您的问题，那么在故事板中，大多数选项旁边都有很少的加号按钮，以便您可以自定义标签和属性。确保您使用的不是纯文本，而是属性文本，它是列中的第一个下拉选项。
I hope this helps, let me know if I'm not understanding properly!
我希望这会有所帮助，如果我没有正确理解，请告诉我！

Checkout @IBInspectable and @IBDesignable. Create a Subclass or Extension for UILabel.
签出@IBInspectable 和@IBDesignable。为 UILabel 创建子类或扩展。
import UIKit
@IBDesignable class AttributedStringLabel: UILabel {
@IBInspectable open var firstText: String = ""
@IBInspectable open var firstColor: UIColor?
@IBInspectable open var secondColor: UIColor?
@IBInspectable open var thirdColor: UIColor?
override func awakeFromNib() {
super.awakeFromNib()
let attrString :NSMutableAttributedString = NSAttributedString([![string][1]][1]: firstText) as! NSMutableAttributedString
attrString.addAttribute(NSForegroundColorAttributeName, value: firstColor! as UIColor, range: NSMakeRange(0, 5))
attrString.addAttribute(NSForegroundColorAttributeName, value: secondColor! as UIColor, range: NSMakeRange(5, 6))
attrString.addAttribute(NSForegroundColorAttributeName, value: thirdColor! as UIColor, range: NSMakeRange(11, 15))
self.attributedText = attrString
}
}
Below is the screenshot, you can customize code as you required, you can add Range whatever you want as IBInspectable variable.
下面是屏幕截图，您可以根据需要自定义代码，您可以添加任何您想要的 Range 作为 IBInspectable 变量。
