I am writing an app where, I can enter URL of a mp3 file from web and when i click download, the app will download it in the app. Can someone help me ? I am new to ios development. I am trying to learn Swift
Xcode 8 • Swift 3
if let audioUrl = URL(string: "http://freetone.org/ring/stan/iPhone_5-Alarm.mp3") {
// then lets create your document folder url
let documentsDirectoryURL = FileManager.default.urls(for: .documentDirectory, in: .userDomainMask).first!
// lets create your destination file url
let destinationUrl = documentsDirectoryURL.appendingPathComponent(audioUrl.lastPathComponent)
print(destinationUrl)
// to check if it exists before downloading it
if FileManager.default.fileExists(atPath: destinationUrl.path) {
print("The file already exists at path")
// if the file doesn't exist
} else {
// you can use NSURLSession.sharedSession to download the data asynchronously
URLSession.shared.downloadTask(with: audioUrl) { location, response, error in
guard let location = location, error == nil else { return }
do {
// after downloading your file you need to move it to your destination url
try FileManager.default.moveItem(at: location, to: destinationUrl)
print("File moved to documents folder")
} catch {
print(error)
}
}.resume()
}
}
