XCode 4.4 remote Image in a Custom Cell Table View

Question

I'm new in Xcode Programming and I'm developing a small application but I have a problem.

I have a Table View with a Custom Cell, taking externally the data to populate the view (by JSon). I have a big slow navigation in list because in the method - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath. I get an external image and this makes it all slow because it runs every time a cell displayed.

How can I populate the entire list without using this method? Or is there an alternative to make it understand that the image exists?

Answer 1

There are few methods Apple suggests when customizing your UITableViewCell. You probably is trying to add subviews to the contentView of the cell. A better approach is described here Subclassing UITableViewCell. Well, I suggest you read the TableView Programming guide.
