How to tell a UITableView to preload all Rows?
- by Infinite
Is there a way to tell a UITableView to preload all rows?
The tableView is supposed to show several comments (up to 80 comments).
So my CommentCell uses a Setter to adapt the cell to a specific comment.
-(void)setComment:(Comment *)newComment {
if (newComment != comment) {
[comment release];
comment = [newComment retain];
/*
* set the cells view variables here
*/
}
}
This specific setter takes quite a bunch of processing resources and scrolling gets kinda laggy.
I am using a comment-specific reuseIdentifier instead of a static cellIdentifier when calling
dequeueReusableCellWithIdentifier:
in order to assure, that "newComment" equals the old "comment".
And in fact this does work great when scrolling over cells which have already been loaded.
But when scrolling through the comments for the first time, it still lags like hell.
Which leads me to my question:
Is there a way to tell the tableview to preload all cells? (which I doubt)
or
Do I have to implement my own cache instead of relying on "dequeueReusableCellWithIdentifier:"?
