Hi, i have a problem, while download photos from my server get this error.
Error dnssd_clientstub deliver_request: socketpair failed 24 (Too many open files)
__NSCFLocalDownloadFile: error 24 opening for ioChannel, file: /private/var/mobile/Containers/Data/Application/6C28AF76-1BFA-4324-935A-E3655D273986/tmp/CFNetworkDownload_6VkNHA.tmp
There are 5000 photos and only download 300. I think alamofire download all photos simultaneus and the iphone memory crash.
This is my source code and my platform is, xcode 8, swift 3.0.1 and iphone 6 64gb with the latest iOS,
Thanks.
func SyncFotos() {
let parametro: Parameters = [
"empresa": "lita8x",
"inventario": "1"
]
self.lblSync2.text = "Sincronizando Fotos"
Alamofire.request("http://litani2.dyndns.org:8080/litani-web/webservice/articulosa.php", parameters: parametro, encoding: URLEncoding.default)
.responseJSON { response in
if let result = response.result.value {
if((result) != nil) {
let swiftyJsonVar = JSON(result)
if let resData = swiftyJsonVar["productos"].arrayObject {
let arrRes = resData as! [[String:AnyObject]]
let xcuenta = arrRes.count
var xconteo = 0
DispatchQueue.global(qos: .background).async {
for articulo in arrRes {
let xcodigo = articulo["codigo"] as! String
let nombre = xcodigo+".jpg"
// Eliminamos la foto primero
let documentsURL = FileManager.default.urls(for: .documentDirectory, in: .userDomainMask).first!
let filePath = documentsURL.appendingPathComponent(nombre).path
if FileManager.default.fileExists(atPath: filePath) {
// try! FileManager.default.removeItem(atPath: filePath)
} else {
let url = "http://litani2.dyndns.org:8080/litani-web/imagenes/"+nombre
let destination = DownloadRequest.suggestedDownloadDestination(for: .documentDirectory)
Alamofire.download(url, to: destination).response { response in
print("DEBUG: Request \(nombre)")
}
print(url)
}
xconteo=xconteo+1
DispatchQueue.main.async {
self.lblSync2.text = "Sincronizando Fotos \(xconteo) de \(xcuenta)"
if (xconteo == xcuenta) {
self.lblSync2.text = "Fotos Sincronizadas"
}
}
}
} // Dispatch
} // if let resData
} // if((result) != nil)
} // if let result
self.lblSync2.text = "Sincronizar Fotos Culminado"
}
}
