Question

each cell in my table has a label, with maximum three lines, so the cell height depends on the label’s height, I know the delegate method that returns height for a specific cell(NSIndexPath), but I need to get the actual cell in order to determine the height, and if I call cellForRow:atIndexPath: in heightForCell:, it loops infinitely, I guess cellForRow also calls heightForCell. So is there any way I can handle this?

Thanks!

You can use NSStrings size for string in the heightForRow: delegate method e.g.

CGSize maxSize = CGSizeMake(300, 800); //max x width and y height
NSString *cellTitle = @"Lorem ipsum";
UIFont *stringFont = [UIFont systemFontOfSize:14]; // use the same font your using on the cell
CGSize cellStringSize = [myString sizeWithFont:stringFont constrainedToSize:maximumSize lineBreakMode: UILineBreakModeWordWrap];

This will give you a CGSize you can then use the height from here and add a little padding. You can find more information here: http://developer.apple.com/library/ios/#documentation/UIKit/Reference/NSString_UIKit_Additions/Reference/Reference.html
