Xcode 告诉我输入预期的 ',' 分隔符

Question

xcode 告诉我输入预期的 ',' 分隔符。下面是我的代码。即使我输入 Xcode 告诉我的内容，我仍然会收到错误消息。有谁知道我可能做错了什么？

        } else {

            if let p = placemarks?[0] {

                var subThoroughfare:String = ""

                if (p.throughfare != nil {

                    subThoroughfare = p.subThoroughfare

            } // there are telling me to put this ',' here


                self.addressLabel.text = "\(subThoroughfare) \(p.thoroughfare) \n \(p.subLocality) \n \(p.subAdministrativeArea) \n \(p.postalCode) \n \(p.country)"

                } // xcode is telling me to put this ',' here

        } // xcode is telling me to put this ',' here            



    })

Answer 1

更改这部分代码并检查它是否仍然显示错误：

if (p.throughfare != nil) {  
  subThoroughfare = p.subThoroughfare
}

如果它仍然显示错误，请在您的代码中也显示 if 部分，这将有助于理解完整代码，因为末尾看起来也有额外的括号
