问题
I am trying to build a tableview cell that include videos in it. I am keeping my cell in nscache as I saw in another post in stack overflow. There goes my code:
Firstly I am calling this in viewDidload() and when index path.row %5=0
cache = NSMutableDictionary()
do {
// create post request
let url = NSURL(string: "http://molocate.elasticbeanstalk.com/video/api/explore/all/")!
let request = NSMutableURLRequest(URL: url)
request.HTTPMethod = "GET"
// insert json data to the request
//print(userToken)
request.addValue("application/json", forHTTPHeaderField: "Content-Type")
request.addValue("application/json", forHTTPHeaderField: "Accept")
request.addValue("Token "+userToken!, forHTTPHeaderField: "Authorization")
// let task = NSURLSession.sharedSession().dataTaskWithRequest(request){ data, response, error in
let task = NSURLSession.sharedSession().dataTaskWithRequest(request){ (data, response, error) -> Void in
dispatch_async(dispatch_get_main_queue(), {
//print(response)
//print(NSString(data: data!, encoding: NSUTF8StringEncoding))
if error != nil{
print("Error -> \(error)")
//return
}
do {
let result = try NSJSONSerialization.JSONObjectWithData(data!, options: .MutableContainers)
print("Result -> \(result)")
let videos = result["results"] as! NSArray
if result["next"] is NSNull {
print("next is null")
self.nextURL = nil
}else {
let nextStr = result["next"] as! String
print(nextStr)
self.nextURL = NSURL(string: nextStr)
}
for item in videos {
var videoStr = videoInf()
let urlString = item["video_url"] as! String
let url = NSURL(string: urlString)
videoStr.urlSta = url!
let username = item["current_username"] as! String
videoStr.username = username
self.videoArray.append(videoStr)
}
} catch {
print("Error -> \(error)")
}
self.tableView.reloadData()
})
}
task.resume()
} catch {
print(error)
}
Then, There is my code about my table view cell
var cell = videoCell(style: UITableViewCellStyle.Default, reuseIdentifier: "myIdentifier")
if((cache.objectForKey(NSString(format: "key%lu", indexPath.row))) != nil){
cell = cache.objectForKey(NSString(format: "key%lu", indexPath.row)) as! videoCell
cell.player.play()
}else{
cell.tableVideoURL = videoArray[indexPath.row].urlSta
cell.exploreAddView()
}
But When I am at the 14th video my app is giving me a memory error and I could not to any utility of my app and the other cell have a place but they are not giving a video.
