Swift 解析进度 block : extra argument in call

Question

错误提示:调用中存在额外参数“progressBlock”。怎么了？

pin.saveInBackgroundWithBlock({(success, error) -> Void in
    if success == false {
        ...
     } else {
          ...
      }

  },
    progressBlock: { (amountDone: CInt) -> Void in
        var percent = Float(amountDone)
        elf.progressIndicatorView.progress = CGFloat(percent)/100

        self.progressIndicatorView.reveal()

  })

尝试:

 pin.saveInBackgroundWithBlock({ (succeeded: Bool, error: NSError?) -> Void in
    // Handle success or failure here ...
    if succeeded {
        println("Save successful")
    } else {
        println("Save unsuccessful: \(error?.userInfo)")
    }

    }, progressBlock: { (amountDone: Int32) -> Void in
          var percent = Float(amountDone)
          self.progressIndicatorView.progress = CGFloat(percent)/100
          self.progressIndicatorView.reveal()
})
