sessid = (NSString *)[array4 objectAtIndex:indexPath.row];
token = (NSString *)[array6 objectAtIndex:indexPath.row];
apikey = (NSString *)[array7 objectAtIndex:indexPath.row];
NSLog(@"%@,%@",sessid,token);
NSString *stat =(NSString *)[array2 objectAtIndex:indexPath.row];
NSLog(@"%@",stat);
NSString *trimmedString = [stat stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet]];
if([trimmedString isEqualToString:@"Two Way Video Streaming"] || [trimmedString isEqualToString:@"One Way Video Streaming"]) {
    [cell.startvideo setHidden:FALSE];
    [cell.startvideo setImage:[UIImage imageNamed:@"ca_video.png"] forState:UIControlStateNormal];
    [cell.startvideo addTarget:self action:@selector(playAction) forControlEvents:UIControlEventTouchUpInside];
}
else
    [cell.startvideo setHidden:TRUE];
return  cell;

}

NSJSONSerialization never creates a NSData object. So, I'm wondering where you did get that NSData object. Anyway, if your html is embedded in JSON it is very likely already represented as a NSString. — CouchDeveloper

please paste you code. that will help in finding the issue. i think you are requesting html data from back end. — Pawan Rai

Try initWithData:encoding: method of NSString to create a string with your data.

Example:

NSString *str = [[NSString alloc] initWithData:someData encoding:NSUTF8StringEncoding];

Hope it helps. Happy coding :)

Convert a NSString with HTML into a plain text string using NSXMLParser

NSString *urlString = @"www.myurl.com";
NSString *agentString = @"Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10_5_6; en-us) AppleWebKit/525.27.1 (KHTML, like Gecko) Version/3.2.1 Safari/525.27.1";
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:
[NSURL URLWithString:urlString]];
[request setValue:agentString forHTTPHeaderField:@"User-Agent"];
NSData *data = [ NSURLConnection sendSynchronousRequest:request returningResponse: nil error: nil ];
NSString *returnData = [[NSString alloc] initWithBytes: [data bytes] length:[data length] encoding: NSUTF8StringEncoding];

NSLog(returnData);
