如何从一组网址获取单个URL？(How get Single Url From an Array of urls?)

 这是我的代码： 
 
  urll = NSURL(string: "http://xxxxxxxxxxx.com/api/?slider=uij6sdnb")
    let session = NSURLSession.sharedSession()
    let task = session.dataTaskWithURL(urll) {(NSData, response, error) -> Void in
        do {
            let records = try NSJSONSerialization.JSONObjectWithData(NSData!, options: NSJSONReadingOptions.MutableContainers) as! NSArray
            for record in records {
                //                    let urlid = Int(record["slide_id"] as! String)
                let urimage = record["slide_url"] as! String
                self.urls = [urimage]
                print(self.urls.count)
                                }
        }

        catch {
            print("Json Error")

        }
    }

    task.resume()
 
 我打印时： 
 
              print(urimage)
 
 它给了我4个这样的网址： 
 
 HTTP：//sdkladlkasjd1.jpg 
 
 HTTP：//sdkladlkasjd2.jpg 
 
 HTTP：//sdkladlkasjd3.jpg 
 
 HTTP：//sdkladlkasjd4.jpg 
 
 当我打印： 
 
              print(urimage[1])
 
 它让我觉得：'subscript'不可用：不能使用Int下标String，请参阅文档注释以供讨论 
 
 当我把它放在另一个值时： 
 
var urls = [String]()
self.urls = [urimage]
 
 我打印： 
 
                print(self.urls.count)
 
 它给了我 
 
 1

This is My Code:
 
  urll = NSURL(string: "http://xxxxxxxxxxx.com/api/?slider=uij6sdnb")
    let session = NSURLSession.sharedSession()
    let task = session.dataTaskWithURL(urll) {(NSData, response, error) -> Void in
        do {
            let records = try NSJSONSerialization.JSONObjectWithData(NSData!, options: NSJSONReadingOptions.MutableContainers) as! NSArray
            for record in records {
                //                    let urlid = Int(record["slide_id"] as! String)
                let urimage = record["slide_url"] as! String
                self.urls = [urimage]
                print(self.urls.count)
                                }
        }

        catch {
            print("Json Error")

        }
    }

    task.resume()
 
When I Print :
 
              print(urimage)
 
it gaves me 4 url like this:
 
http://sdkladlkasjd1.jpg
 
http://sdkladlkasjd2.jpg
 
http://sdkladlkasjd3.jpg
 
http://sdkladlkasjd4.jpg
 
When I print:
 
              print(urimage[1])
 
It gaves me : 'subscript' is unavailable: cannot subscript String with an Int, see the documentation comment for discussion
 
When i put it in another value :
 
var urls = [String]()
self.urls = [urimage]
 
and I print:
 
                print(self.urls.count)
 
it gaves me
