9,411 Pointsresizing a UITableViewCell on button press.
In my app, i have a custom tableViewCell with a label at the bottom and an image at the top. I have set the number of lines on the label to 3 and if the text in the label exceeds this, it just has '...' at the end, however when a user clicks 'read more' I would like the cell to expand and the full contents of the label to be displayed. I have searched high and low on the internet and most of their suggestions have been depreciated. Any help is much appreciated. Kieran

Courses Plus Student 2,549 PointsYou have to modify the view cell with this method
- (CGFloat) tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath {
int height = 80;
// Logic when the user pressed a button click more
if (self.readMore == true)
height = 100;
return height;
}

9,411 Pointsthank you for the reply Camillo! I have tried what you said, I have set the height initially to 80, but i am having trouble writing the logic to add the logic for the true/false of the button press. My button to expand is called "expandButton" so would i replace self.readmore with self.expandButton?

Courses Plus Student 2,549 PointsIn that case you need a protocol in a custom UITableViewCell class. And when the "Read More" Button is clicked you need to set the selected state in an array.
Here's a Sample Code
