I am using the method tableView:indexPathForCell
to implement a custom delegate that can dynamically resize a UITableViewCell
based on the frame size of the UIWebView
that is inside of it. The problem is that tableView:indexPathForCell
is returning nil
when I try to find out what the indexPath of a particular cell is:
- (void)trialSummaryTableViewCell:(TrialSummaryTableViewCell *)cell shouldAssignHeight:(CGFloat)newHeight {
NSIndexPath *indexPath = [tableV indexPathForCell:cell];
NSLog(@"tableV: %@\ncell: %@\nindexPath: %@", tableV, cell, indexPath); //<--
// ...
}
Here, tableV
does not return nil
, cell does not return nil
, but indexPath
returns nil
.
What am I doing wrong?
Edit: I am calling -(void)trialSummaryTableViewCell
from the tableView:cellForRowAtIndexPath:
method
It could be that the cell is not visible at this moment. tableView:indexPathForCell returns nil in this situation. I solved this using indexPathForRowAtPoint this method works even if the cell is not visible. The code:
UITableViewCell *cell = textField.superview.superview;
NSIndexPath *indexPath = [self.tableView indexPathForRowAtPoint:cell.center];
