Question

我将代码从XCode 6.4迁移到7，这个错误似乎无法解决。

func onHoldReasonAttributedTextSetup(onHoldReson : String) -> NSMutableAttributedString
{

    let markerFontAttributes : [NSObject : AnyObject]? = [
      NSFontAttributeName : UIFont(name: "HelveticaNeue", size: 12.0)!,
      NSForegroundColorAttributeName : UIColor(red: 0/255, green: 152/255, blue: 204/255, alpha: 1.0)
    ]
    let onHoldText = NSAttributedString(string: "On Hold: ", attributes: markerFontAttributes)
    let onHoldReasonText  = NSAttributedString(string:onHoldReson)
    var string = NSMutableAttributedString()
    string.appendAttributedString(onHoldText)
    string.appendAttributedString(onHoldReasonText)
    return string
}

您需要更改此行：

let markerFontAttributes : [NSObject : AnyObject]? = [
      NSFontAttributeName : UIFont(name: "HelveticaNeue", size: 12.0)!,
      NSForegroundColorAttributeName : UIColor(red: 0/255, green: 152/255, blue: 204/255, alpha: 1.0)
    ]

到

let markerFontAttributes : [String : AnyObject]? = [
      NSFontAttributeName : UIFont(name: "HelveticaNeue", size: 12.0)!,
      NSForegroundColorAttributeName : UIColor(red: 0/255, green: 152/255, blue: 204/255, alpha: 1.0)
    ]

因为初始化程序需要[String : AnyObject]?格式的字典：

init(string str: String, attributes attrs: [String : AnyObject]?)

参考：NSAttributedString Class Reference

无法使用类型的参数列表调用NSAttributedString类型的初始值设定项（字符串：字符串，属性：[NSObject：AnyObject]？）
