如何使用Swift设置UILabel中不同的字体大小和颜色?
我需要将字符串的第一个字符与其余部分使用不同的颜色和大小。
假设您想要一个像这样更小和灰色的货币符号:
只需使用NSMutableAttributedString
对象:
let amountText = NSMutableAttributedString.init(string: "€ 60,00")
// set the custom font and color for the 0,1 range in string
amountText.setAttributes([NSFontAttributeName: UIFont.systemFontOfSize(12),
NSForegroundColorAttributeName: UIColor.grayColor()],
range: NSMakeRange(0, 1))
// if you want, you can add more attributes for different ranges calling .setAttributes many times
// set the attributed string to the UILabel object
myUILabel.attributedText = amountText
Swift 5.3:
let amountText = NSMutableAttributedString.init(string: "€ 60,00")
// set the custom font and color for the 0,1 range in string
amountText.setAttributes([NSAttributedString.Key.font: UIFont.systemFont(ofSize: 12),
NSAttributedString.Key.foregroundColor: UIColor.gray],
range: NSMakeRange(0, 1))
// if you want, you can add more attributes for different ranges calling .setAttributes many times
// set the attributed string to the UILabel object
// set the attributed string to the UILabel object
myUILabel.attributedText = amountText
