Show progress bar until the video loads iOS7

Question

Hi in my application I am playing a video using a URL. I transmit the video URL of my server, now the problem is it takes a long time to play the video. So I want to show a progress bar until it loads the video.

So, I used MBProgressHUD for the progress bar showing the progress bar but the video is not playing, please tell me where I am doing wrong.

My code.

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {

     NSString * currentVideo = [videoarray1 objectAtIndex:indexPath.row];

     NSString *strurl=[self urlencode:currentVideo];
     NSURL *url=[NSURL URLWithString:strurl];
     NSURLRequest *req=[NSURLRequest requestWithURL:url];
     NSURLConnection *con=[NSURLConnection connectionWithRequest:req delegate:self];
  if (con) {

      datas=[[NSMutableData alloc]init];

  }
     spinner =  [MBProgressHUD showHUDAddedTo:self.view animated:YES];

     spinner.mode = MBProgressHUDModeCustomView;

     [spinner setLabelText:@"Loading file....."];

     [spinner setLabelFont:[UIFont systemFontOfSize:15]];

     [spinner show:YES];

 }


-(NSString *)urlencode:(NSString *)str
 {
      NSString *encodeString=(NSString *)CFBridgingRelease(CFURLCreateStringByAddingPercentEscapes(NULL, (CFStringRef)str, NULL, (CFStringRef)@"", kCFStringEncodingUTF8));
      return encodeString;
 }
- (void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response{
     NSLog(@"%lld",[response expectedContentLength]);

     self.length = [response expectedContentLength];
 }
- (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data1{
[datas appendData:data1];

    float progress =  (float)[datas length]/(float)self.length;
    NSLog(@"%f",progress);

   float check=progress*100;
   if (check==100) {
      [spinner hide:YES];

      [spinner removeFromSuperViewOnHide];

  }

}

 - (void)connectionDidFinishLoading:(NSURLConnection *)connection{

      NSData *data = datas;
      NSLog(@"%@",data);
      NSString* myurl;
      myurl = [[NSString alloc] initWithData:datas encoding:NSASCIIStringEncoding];
NSLog(@"%@",myurl);

   _movieplayer = [[MPMoviePlayerController alloc]initWithContentURL: [NSURL URLWithString:myurl]];
  [[_movieplayer view] setFrame: CGRectMake(0, 0, self.view.bounds.size.width, self.view.bounds.size.height)];

  [self.view addSubview: [_movieplayer view]];
  [_movieplayer setShouldAutoplay:YES];
  [_movieplayer prepareToPlay];
  [_movieplayer play];


}

I used the code above without playing the video, tell me where I am doing wrong in the code above how to do it.

Thank.

1.

2., videoarray1 nextvieww.

3.add nextview control

- (void)viewDidLoad
{
    [super viewDidLoad];
    self.indicator = [[UIActivityIndicatorView alloc] initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleWhiteLarge];
    self.indicator.frame = CGRectMake(0.0, 0.0, 40.0, 40.0);
    self.indicator.center = self.view.center;
    [self.view addSubview:self.indicator];
    [self.indicator startAnimating];

    _movieplayer = [[MPMoviePlayerController alloc]initWithContentURL: [NSURL URLWithString:[self urlencode:self.strPlayUrl]]];
    [[_movieplayer view] setFrame: CGRectMake(0, 0, self.view.bounds.size.width, self.view.bounds.size.height)];
    [self.view addSubview: [_movieplayer view]];
    [_movieplayer setShouldAutoplay:YES];
    [_movieplayer prepareToPlay];

    //this is the line we need to do
    [self.view insertSubview:self.movieplayer.view belowSubview:self.indicator];
    [self.movieplayer play];
}
- (void)viewDidAppear:(BOOL)animated {
    NSLog(@"VIEW DID LOAD");
    // Register to receive a notification that the movie is now in memory and ready to play
    [[NSNotificationCenter defaultCenter] addObserver:self
                                             selector:@selector(movieLoadStateDidChange:)
                                                 name:MPMoviePlayerLoadStateDidChangeNotification
                                               object:nil];

}

-(void)movieLoadStateDidChange:(id)sender
{
    NSLog(@"STATE CHANGED");
    if(MPMovieLoadStatePlaythroughOK ) {
        NSLog(@"State is Playable OK");
        NSLog(@"Enough data has been buffered for playback to continue uninterrupted..");
         self.indicator.hidden = YES;
        [ self.indicator stopAnimating];
    }

}


-(NSString *)urlencode:(NSString *)str
{
    NSString *encodeString=(NSString *)CFBridgingRelease(CFURLCreateStringByAddingPercentEscapes(NULL, (CFStringRef)str, NULL, (CFStringRef)@"", kCFStringEncodingUTF8));
    return encodeString;
}
