Issue converting NSData Object into NSDictionary - json

Question

I'm trying to extract information from a JSON file. Is it possible there is something wrong with the JSON output? There seems to be some strange encoding. It's from a blog.
JSON:
[{
"title": "A visit to McSorley\u0027s Old Ale House",
"subtitle": "",
"summary": "\u0026lt;p\u0026gt;McSorley\u0026#39;s Ale House is Manhattan\u0026#39;s oldest pub\u0026lt;/p\u0026gt;"
}]
I successfully create NSData Object, but NSJSONSerialization fails, see the code:
func parseJSON(jsonString: String) -> [String: AnyObject]? {
guard let data: NSData = jsonString.dataUsingEncoding(NSUTF8StringEncoding)
else { return nil }
do {
let dictionary = try NSJSONSerialization.JSONObjectWithData(data, options: []) as? [String: AnyObject]
return dictionary
} catch {
print("JSON Error: \(error)")
return nil
}
}
Thanks!

Your code works fine the problem is your JSON file, try with another JSON file for example, the following one:
var json = "{\"xyz \":[{\"title\": \"\",\"subtitle\": \"\",\"summary\": \"\"}]}"
func parseJSON(jsonString: String) -> [String: AnyObject]? {
guard let data: NSData = jsonString.dataUsingEncoding(NSUTF8StringEncoding)
else { return nil }
do {
let dictionary = try NSJSONSerialization.JSONObjectWithData(data, options: []) as? [String: AnyObject]
return dictionary
} catch {
print("JSON Error: \(error)")
return nil
}
}
The output is:
Optional(["xyz": (
{
subtitle = "";
summary = "";
title = "";
}
)])
You're missing the key for the JSON dictionary, if for that I put it some key in the beginning of the JSON to make it works. Nevertheless I strongly recommend you use SwiftyJSON to parse JSON files in an excellent way.
Removing the HTML String
extension String {
/**
Strip the HTML tags for the string passed.
- parameter code: String to strip HTML.
- returns: The new string without HTML tags.
*/
func stripHtmlTags() -> String {
return self.stringByReplacingOccurrencesOfString("<[^>]+>", withString: "", options: .RegularExpressionSearch, range: nil)
}
}
I hope this help you.
