当试图调用便利init,Swift时调用额外的参数

class WmAttendee{

    var mEmail:string!
    var mname:string!
    var mType:Int!
    var mStatus:string = "0"
    var mRelationShip:string!

    init( email:string,name:string,type:int) {
        self.mEmail = email
        self.mname = name
        self.mType = type
    }

     convenience init( email:string,type:Int,status:string,relationShip:string) {
        self.init(email: email,name: name,type: typE)
        self.mStatus = status
        self.mRelationShip = relationShip
    }
}

当我尝试用5个参数测试第二个构造函数时,我得到：调用中的额外参数’status’

var att1 = WmAttendee(email: "mymail",name: "Somename",type: 1); // OK

var att2 = WmAttendee(email: "mail2",name: "name2",type: 3,status: "2",relationShip: 3)
 // ERROR Extra argument 'status' in call

为什么？我错过了什么吗？

谢谢,
