swift Unescaped control character - ios

Question

I'm trying to get a json from a server and deserialize it, but I try probelas with unescaped control characters.
My code is as follows ...
let urlFinal = "http://000.0000.000.000:8080"
let jsonUrl = urlFinal
let session = NSURLSession.sharedSession()
let shotsUrl = NSURL(string: jsonUrl)
let task = session.dataTaskWithURL(shotsUrl!) {data, response, error in
guard data != nil else {
falha()
return
}
//let json = JSON(data: data!)
//print(json["ServicoCliente"][0]["id"])
do {
let jsonData = try NSJSONSerialization.JSONObjectWithData(data!, options: NSJSONReadingOptions.MutableContainers )
let J = jsonData as! NSDictionary
print(jsonData)
let us = J["ServicoCliente"]
print(us)
dispatch_async(dispatch_get_main_queue(),{
sucesso()
});
} catch _ {
falha()
}
}
task.resume()
and I also tried this using Alamofire 3.0:
Alamofire.request(.GET, "http://000.000.000.000/", parameters: nil)
.responseJSON { response in
debugPrint(response) // prints detailed description of all response properties
print(response.request) // original URL request
print(response.response) // URL response
print(response.data) // server data
print(response.result) // result of response serialization
if let JSON = response.result.value {
print("JSON: \(JSON)")
}
}
And get this error:
Unescaped control character around character 263
How can I remove characters without escape?
I use X-Code 7.3.1 and Swift 2.3
UPDATE:
Json
{"ServicoCliente":[{"id":"195","cliente":"247","enderecoFavoritos":"48","servicoProfissional":"194","ind_estado_cliente":"A","ind_estado_profissional":"","profissional_id":"240","profissional_nome":"PetMax","servicotipo_nome":"Petshop","servicosubtipo_nome":"Tosa ","dta_inc_alt":"2016-11-05 22:56:19.333","ind_finalizado":"N"}]}

Answer 1

To fix this, you must convert the data for string, remove characters and then convert to dataonly then deserialize
let urlFinal = "http://000.0000.000.000:8080"
let jsonUrl = urlFinal
let session = NSURLSession.sharedSession()
let shotsUrl = NSURL(string: jsonUrl)
let task = session.dataTaskWithURL(shotsUrl!) {data, response, error in
guard data != nil else {
falha()
return
}
var dataToString = String(data: data!, encoding: NSUTF8StringEncoding)
dataToString = stringByRemovingControlCharacters2(dataToString!)
let ndata = dataToString!.dataUsingEncoding(NSUTF8StringEncoding)
do {
let jsonData = try NSJSONSerialization.JSONObjectWithData(ndata!, options: NSJSONReadingOptions.MutableContainers )
let J = jsonData as! NSDictionary
print(jsonData)
let us = J["ServicoCliente"]
print(us)
dispatch_async(dispatch_get_main_queue(),{
sucesso()
});
} catch _ {
falha()
}
}
task.resume()
and add the function
func stringByRemovingControlCharacters2(string: String) -> String {
let controlChars = NSCharacterSet.controlCharacterSet()
var range = string.rangeOfCharacterFromSet(controlChars)
var mutable = string
while let removeRange = range {
mutable.removeRange(removeRange)
range = mutable.rangeOfCharacterFromSet(controlChars)
}
return mutable
}

Swift 5
func string(byRemovingControlCharacters inputString: String) -> String {
let controlChars = CharacterSet.controlCharacters
var range = (inputString as NSString).rangeOfCharacter(from: controlChars)
if range.location != NSNotFound {
var mutable = inputString
while range.location != NSNotFound {
if let subRange = Range<String.Index>(range, in: mutable) { mutable.removeSubrange(subRange) }
range = (mutable as NSString).rangeOfCharacter(from: controlChars)
}
return mutable
}
return inputString
}
