Save file with different name using Swift - ios

Question

I am using Alamofire to download files from the server. But i want to name it differently just like how we download the file from web and can name it as we want, same How is it possible in swift
I am using the following code:-
Alamofire.download(fileUrl, to: destination)
.downloadProgress { progress in
print("Download Progress:---------- \
(progress.fractionCompleted)")
}
.responseData { response in
print(response.request)
print(response.response)
print(response.temporaryURL)
print(response.destinationURL)
print(response.error)
}
Prefering not to use alamofire to rename or overrite files. Is there any other method

Answer 1

Here is the hands on function to save your Data into DocumentDirectory with the name you given. This method have one call back which will call after performing saving action, it will return the path where the image saved in directory. This function written in Swift 3.
func saveImageInDocDirectory(data: Data?, fileName: String?, successblock: #escaping (_ path: String?) -> Void) { // To add the image to cache for given identifier.
let paths = NSSearchPathForDirectoriesInDomains( .documentDirectory, .userDomainMask, true)[0] as String
let path = paths.appending("/\(fileName!)")
if !FileManager.default.fileExists(atPath: path) {
do {
try FileManager.default.createDirectory(at: URL(fileURLWithPath: path), withIntermediateDirectories: false, attributes: nil)
} catch {
print("Error creating images folder in Cache dir: \(error)")
}
}
if (filemgr.fileExists(atPath: path)) {
try! filemgr.removeItem(atPath: path)
} else {
do {
try data?.write(to: URL(fileURLWithPath: path, isDirectory: false))
successblock(path)
} catch {
successblock(nil)
print("Error while caching the data in cache folder.")
}
}
}
you can call this method like,
Alamofire.download(fileUrl, to: destination)
.downloadProgress { progress in
print("Download Progress:---------- \
(progress.fractionCompleted)")
}
.responseData { response in
print(response.request)
print(response.response)
print(response.temporaryURL)
print(response.destinationURL)
print(response.error)
if let data = response.result.value {
self.saveImageInDocDirectory(data: data, fileName: "YourFile", successblock: { (path) in
print(path)
}
}
}
Thanks.
