我正在嘗試創(chuàng)建一個(gè)字典，可以將其制成JSON格式的對(duì)象并發(fā)送到服務(wù)器。例：    var users = [["First": "Albert", "Last": "Einstein",     "Address":[        "Street": "112 Mercer Street",        "City": "Princeton"]],["First": "Marie", "Last": "Curie",     "Address":[        "Street": "108 boulevard Kellermann",        "City": "Paris"]]]我用這個(gè)功能func nsobjectToJSON(swiftObject: NSObject) -> NSString {    var jsonCreationError: NSError?    let jsonData: NSData = NSJSONSerialization.dataWithJSONObject(swiftObject, options: NSJSONWritingOptions.PrettyPrinted, error: &jsonCreationError)!    var strJSON = NSString()    if jsonCreationError != nil {        println("Errors: \(jsonCreationError)")    }    else {        // everything is fine and we have our json stored as an NSData object. We can convert into NSString        strJSON =  NSString(data: jsonData, encoding: NSUTF8StringEncoding)!        println("\(strJSON)")    }    return strJSON}但是我的結(jié)果是這樣的：[  {    "First" : "Albert",    "Address" : {      "Street" : "112 Mercer Street",      "City" : "Princeton"    },    "Last" : "Einstein"  },  {    "First" : "Marie",    "Address" : {      "Street" : "108 boulevard Kellermann",      "City" : "Paris"    },    "Last" : "Curie"  }]問(wèn)題：為什么姓氏是姓氏？我認(rèn)為應(yīng)該在地址上方。請(qǐng)讓我知道我在NSDictionary上做錯(cuò)了什么，這才是錯(cuò)誤的。任何幫助將不勝感激-謝謝。
