swift – 通过NSAttributedString进行攻击：“没有更多上下文的表达式是模糊的”

谁能告诉我什么是错的？

let myTitle = NSAttributedString(string: Xdevices[row].deviceName!,attributes: [NSFontAttributeName:UIFont(name: "Georgia",size: 
              15.0)!,NSForegroundColorAttributeName:UIColor.orangeColor(),NsstrikethroughStyleAttributeName: NSUnderlinestyle.StyleSingle])

错误是：

Type of expression is ambiguous without more context

插入NsstrikethroughStyleAttributeName：NSUnderlinestyle.StyleSingle后发生这种情况

解决方法

试试这个：

let attributes = [
    NSFontAttributeName: UIFont(name: "Georgia",size: 15.0)!,NSForegroundColorAttributeName: UIColor.orangeColor(),NsstrikethroughStyleAttributeName: NSNumber(integer: NSUnderlinestyle.StyleSingle.rawValue)
]

let myTitle = NSAttributedString(string: Xdevices[row].deviceName!,attributes: attributes)

NSAttributedString(string：attributes :)需要一个类型为[String：AnyObject]的字典.然而,StyleSingle是一个Int.因此,您必须将其包装在NSNumber中.
