How do I parse JSON from a file in iOS? [closed]

Solution 1:

1. Create empty text file (New File/Other/Empty) e.g. "example.json"

2. Paste json string into the file.

3. Use these lines to get the data:

   NSString *filePath = [[NSBundle mainBundle] pathForResource:@"example" ofType:@"json"];
   NSData *data = [NSData dataWithContentsOfFile:filePath];
   NSArray *json = [NSJSONSerialization JSONObjectWithData:data options:kNilOptions error:nil];
   

Solution 2:

Swift 2.0 version of the accepted answer:

if let filePath = NSBundle.mainBundle().pathForResource("example", ofType: "json"), data = NSData(contentsOfFile: filePath) {
        do {
            let json = try NSJSONSerialization.JSONObjectWithData(data, options: NSJSONReadingOptions.AllowFragments)
        }
        catch {
            //Handle error
        }
    }

I have followed this and it is working fine

NSError *error = nil;
 NSString *filePath = [[NSBundle mainBundle] pathForResource:@"messages" 
                                                      ofType:@"json"];
 NSData *dataFromFile = [NSData dataWithContentsOfFile:filePath];
 NSDictionary *data = [NSJSONSerialization JSONObjectWithData:dataFromFile
                                                      options:kNilOptions
                                                        error:&error];
 if (error != nil) {
  NSLog(@"Error: was not able to load messages.");
  return nil;
 }
