Label中显示自定义颜色或者大小的方式
//富文本设置
var attributeString = NSMutableAttributedString(string:"welcome to hangge.com")
//从文本0开始6个字符字体HelveticaNeue-Bold,16号
attributeString.addAttribute(NSFontAttributeName, value: UIFont(name: "HelveticaNeue-Bold", size: 16)!,
range: NSMakeRange(0,6))
//设置字体颜色
attributeString.addAttribute(NSForegroundColorAttributeName, value: UIColor.blueColor(),
range: NSMakeRange(0, 3))
//设置文字背景颜色
attributeString.addAttribute(NSBackgroundColorAttributeName, value: UIColor.greenColor(),
range: NSMakeRange(3,3))
msgLabel.attributedText = attributeString
显示HTML
var htmlText = "空は<font color=\"blue\">青い</font>。<br>An apple is <font color=\"red\">red</font>."
do{
let attrStr = try NSAttributedString(data: htmlText.dataUsingEncoding(NSUnicodeStringEncoding, allowLossyConversion: true)!, options: [NSDocumentTypeDocumentAttribute: NSHTMLTextDocumentType], documentAttributes: nil)
msgLabel.attributedText = attrStr
}catch let error as NSError {
print(error.localizedDescription)
}
这里不懂为什么要加上do...catch
