Answer 1

You are setting the data like so:

        [_tableData insertObject:title atIndex:0];
        [_tableData insertObject:release_year atIndex:1];
        [_tableData insertObject:themoviedb atIndex:2];
        [_tableData insertObject:original_title atIndex:3]; 

But you are reading out the data like:

        title.text= [_tableData objectAtIndex:indexPath.row];
        release_year.text= [_tableData objectAtIndex:indexPath.row];
        themoviedb.text= [_tableData objectAtIndex:indexPath.row];
        original_title.text= [_tableData objectAtIndex:indexPath.row];

indexPath.row will be the same integer (eg for the first cell in the section it will be 0). So for that cell the title will be set to title.text , release_year.text , themoviedb.text , and original_title.text . This is not what you intend. You should use an NSDictionary and add that to self.tableData. For example you should replace the first bit of code with:

        NSDictionary *movieDictionary = @{@"title":title,@"release_year":release_year,@"themoviedb":themoviedb,@"original_title":original_title};
        [self.tableData addObject:movieDictionary];

The in cellForRowAtIndexPath:

        NSDictionary *movieDictionary = self.tableData[indexPath.row];
        title.text= movieDictionary[@"title"];
        release_year.text= movieDictionary[@"release_year"];
        themoviedb.text= movieDictionary[@"themoviedb"];
        original_title.text= movieDictionary[@"original_title"];

I don't read all code, but this line I think may be wrong.

    dispatch_sync(dispatch_get_main_queue(), ^{
        //self.tableData=[[NSMutableArray alloc]initWithArray:responseObject];
        [self.tab reloadData];
    }); 

GCD write like this , will lock main thread, then UI refresh will not execute, if you want to reloadData , you need write like below

    dispatch_asyn(dispatch_get_main_queue(), ^{
        //self.tableData=[[NSMutableArray alloc]initWithArray:responseObject];
        [self.tab reloadData];
    }); 

Hope will help you.

try this type of code code

 NSURL *URL = [NSURL URLWithString:@"http://api.androidhive.info/songs/albums.php"];
        AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
        manager.responseSerializer.acceptableContentTypes = [manager.responseSerializer.acceptableContentTypes setByAddingObject:@"text/html"];
        [manager GET:URL.absoluteString parameters:nil progress:nil success:^(NSURLSessionTask *task, id responseObject) {
            [MBProgressHUD hideHUDForView:self.view animated:YES];
            cource_data=[responseObject valueForKey:@"name"];
             NSLog(@"JSON: %@", cource_data);
            [self.tbl_cource reloadData];
        } failure:^(NSURLSessionTask *operation, NSError *error) {
            NSLog(@"Error: %@", error);
   }];
