I am making a custom ui table view cell. I know i can use `loadNibNamed` method to use `.xib`
of the cell but that causes scrolling to be slow when my I have too much data in it .

I want to use UI nib because its lot faster than `loadNibNamed` method for loading custom cell `.xib` file . 

```
static NSString *cellIdentifier = @"PostStreamCell";

PostStreamCell *cell= [tableView dequeueReusableCellWithIdentifier:cellIdentifier];

if (cell == nil)
{
    NSArray *nib = [[NSBundle mainBundle] loadNibNamed:@"PostStreamCell" owner:self options:nil];
    cell = [nib objectAtIndex:0];    
    UINib *cellNib = [UINib nibWithNibName:@"MemberCell" bundle:nil];  
    [cell.collectionView registerNib:cellNib forCellWithReuseIdentifier:@"MemberCell"];
}

cell.textlabel.text =@"xyzabc123";

```

I tried using code below in above "if "block but failed to use it. Any help would be appreciated.

```
UINib *cellNib = [UINib nibWithNibName:@"PostStreamCell" bundle:nil];      
[cell registerNib:cellNib forCellWithReuseIdentifier:@"PostStreamCell"];

```
