Parsing JSON file from folder - NSTemporaryDirectory - json

Question

I have got a file downloaded from AWS S3 to my NSTemporaryDirectory using this code:
let downloadFilePath = (NSTemporaryDirectory() as NSString).stringByAppendingPathComponent("FILENAME")
let downloadingFileURL = NSURL(fileURLWithPath:downloadFilePath)
let downloadRequest: AWSS3TransferManagerDownloadRequest = AWSS3TransferManagerDownloadRequest();
downloadRequest.bucket = "Bucketname";
downloadRequest.key = "FileName";
downloadRequest.downloadingFileURL = downloadingFileURL;
The file = .json file
the apps content is all saved on the JSON file, therefore i need to redirect the file from the NSTemporaryDirectory in order for the content to appear on the application.
Does anyone know the parse function in order to load the data from my JSON file into the application?
Thank you

Answer 1

You cannot modify the main bundle, so this isn't going to work.
There are a few directories under your control, for example the home directory, the application support directory, cache directories, or possibly the document directory.

Answer 2

As gnasher729 notes, you can't modify the main bundle itself, but there's no reason to here. You don't need to move the file in order to display it. You can read from your temporary directory. It's inside your application sandbox, and there's nothing special about it (it doesn't even get cleaned up for you either, so that's your responsibility if you need that).
The temp directory isn't backed up, so if you want that, you should move this to your documents directory. See NSFileManager moveItemAtPath:toPath:error: if you want to do that (or just download to your documents directory in the first place).

Answer 3

I figured it out.
So after downloading the File:
let downloadFilePath = (NSTemporaryDirectory() as NSString).stringByAppendingPathComponent("FILENAME")
let downloadingFileURL = NSURL(fileURLWithPath:downloadFilePath)
let downloadRequest: AWSS3TransferManagerDownloadRequest = AWSS3TransferManagerDownloadRequest();
downloadRequest.bucket = "Bucketname";
downloadRequest.key = "FileName";
downloadRequest.downloadingFileURL = downloadingFileURL;
i have to submit the download request - as seen below:
// submit download request
let transferManager: AWSS3TransferManager = AWSS3TransferManager.defaultS3TransferManager();
print("Downloading started, please wait...");
transferManager.download(downloadRequest).continueWithExecutor(AWSExecutor.defaultExecutor(), block: { (task) -> AnyObject? in
print("TASK:::::: \(task)");
if (task.error != nil){
print("Error Downloading");
}else{
self.readFile()
print("Download complete");
}
return nil;
}, cancellationToken: nil)
}
create a function that will parse your JSON file through the temp directory, using AlamoFire and SwiftyJSON:
func readFile() {
// JSON parsing step (from temporary directory)
let path = (NSTemporaryDirectory() as NSString).stringByAppendingPathComponent("FILENAME")
do {
let readFile:NSString? = try NSString(contentsOfFile: path, encoding: NSUTF8StringEncoding)
let json = JSON.parse(readFile as String!)
for (_, subJson) in json["FILECONTENT"] {
let version = subJson["FILECONTENT"].string
let newsletter = Edition(Version: version!)
self.editions.append(ARRAYNAME!)
}
dispatch_async(dispatch_get_main_queue()) {
self.tableView.reloadData()
}
//print(readFile)
} catch {
}
}
this will showcase the text on your application when ran.
I am trying to get the images to do the something now.
