I need to convert a anyObject that comes from a JSON of a web service to Int32 I have tried in many ways but none of them have happened to me. The last one I have is this:
let puntos = "\(objeto["CATPUNTOS"])" as? NSString
cat.catPuntos = Int32(String(puntos!))!
where cat is an object, when executing it I get this error on the second line
"fatal error: unexpectedly found nil while unwrapping an Optional value "EXC_BAD_INSTRUCTION (code: exc_1386_invop)
// SYNCHRONY OF CATEGORIES let dir = Helpers.REQUESTAPIURL + "/ synchronizeCategoriesApp? userID = (userID!)" let url: NSURL = NSURL (string: dir)! let session = NSURLSession.sharedSession () let request = NSMutableURLRequest (URL: url) let task = session.dataTaskWithRequest (request, completionHandler: {data, response, error -> Void in if (error! = nil) { print (error! .localizedDescription) } else { let nsdata: NSData = NSData (data: data!)
if(nsdata != ""){
do{
let json = try NSJSONSerialization.JSONObjectWithData(nsdata, options: NSJSONReadingOptions.MutableContainers)
let arregloJsonList = json["categorias"] as? NSArray
if let nsArrayJsonList = arregloJsonList {
nsArrayJsonList.enumerateObjectsUsingBlock({objeto, index, stop in
var datos: NSMutableArray = NSMutableArray()
self.idCat = "\(objeto["catId"])" as? NSString
datos = ModeloBD.getInstance().findCategoriaByExternalId(String(self.idCat!))
var cat:CategoriaData = CategoriaData()
if datos.count > 0{
cat = datos.objectAtIndex(0) as! CategoriaData
}
if cat.id == 0{
if objeto["catOperacion"] as? String == "I"{
print("aqui: \(objeto["CATNOMBRE"] as! String)")
cat.externalId = Int32(self.idCat! as String)!
cat.catNombre = objeto["CATNOMBRE"] as! String
cat.catPuntos = ("\(objeto["CATPUNTOS"])" as? NSString)!.intValue
cat.catEstado = ("\(objeto["CATESTADO"])" as? NSString)!.intValue
cat.catVersion = ("\(objeto["CATVERSION"])" as? NSString)!.intValue
cat.catOperacion = String(objeto["CATOPERACION"])
ModeloBD.getInstance().registrarCategoria(cat)
}
}
else{
if cat.catVersion < objeto["catVersion"] as? Int32{
if objeto["catOperacion"] as? String == "U"{
ModeloBD.getInstance().updateCategoria(cat)
}
else if objeto["catOperacion"] as? String == "D"{
ModeloBD.getInstance().removeCategoria(String(self.idCat))
}
}
}
})
}
}catch{
self.msn = "Error al serealizar JSON"
dispatch_async(dispatch_get_main_queue()) {
self.mostrarAlert()
}
}
}
else{
self.msn = "Error, al sincronizar"
dispatch_async(dispatch_get_main_queue()) {
self.mostrarAlert()
}
}
}
})
task.resume()
You must ensure that the "Object" that you have as AnyObject is a data structure so that you can ask for the value of the key "CATCHES" and that String convert it to Number.
if let obj = objeto as? [NSObject: AnyObject] {
if let puntos = obj["CATPUNTOS"] as? String {
cat.catPuntos = Int32(puntos) ?? 0
}else{
cat.catPuntos = 0;
}
}
You can also use link to save some validations
