I have a problem when I get cell in UITableView. It cause of crash my app and show log:

warning: could not load any Objective-C class information. This will significantly reduce the quality of type information available.

And it's my code: 

- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath{
    CustomCell *cell = [_theTableView cellForRowAtIndexPath:indexPath];
    CGSize labelSize = [cell.timeLabel.text sizeWithAttributes:@{NSFontAttributeName:cell.timeLabel.font}];
    CGFloat timeLabelHeight = labelSize.height;

It alway break and crash on line 

CustomCell *cell = [_theTableView cellForRowAtIndexPath:indexPath];

you should change the code you typed:

CustomCell *cell = [_theTableView cellForRowAtIndexPath:indexPath];

to as following:

CustomCell *cell = [self tableView:tableView cellForRowAtIndexPath:indexPath]
