Fit Text in UItableView Cell - ios

Question

I have a long label that is my first label, and I want to fit it in my cell. This is what I have but it isn't working.
I have a custom UITabelviewCell with a few labels in it.
-(CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath {
switch (indexPath.row) {
case 0:{
CGSize constraint = CGSizeMake(CELL_CONTENT_WIDTH - (CELL_CONTENT_MARGIN * 2), 20000.0f);
CGSize size = [diningHallTimes[indexPath.row][#"description"] sizeWithFont:[UIFont systemFontOfSize:FONT_SIZE] constrainedToSize:constraint lineBreakMode:NSLineBreakByWordWrapping];
CGFloat height = MAX(size.height, 44.0f);
return height + (CELL_CONTENT_MARGIN * 2) + 40;
// return myStringSize.height;
break;
}
default:
return 40;
break;
}
}
Here is cell for row
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
DiningInfoTableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:#"Cell" forIndexPath:indexPath];
CGSize constraint = CGSizeMake(CELL_CONTENT_WIDTH - (CELL_CONTENT_MARGIN * 2), 20000.0f);
CGSize size = [diningHallTimes[indexPath.row][#"description"] sizeWithFont:[UIFont systemFontOfSize:FONT_SIZE] constrainedToSize:constraint lineBreakMode:NSLineBreakByWordWrapping];
CGFloat height = MAX(size.height, 44.0f);
CGFloat the = height + (CELL_CONTENT_MARGIN * 2);
cell.descriptionLabel.numberOfLines = 0;
[cell.descriptionLabel setFrame:CGRectMake(20, 0, 280, the)];
NSLog(#"%f", the);
cell.descriptionLabel.text = diningHallTimes[indexPath.row][#"description"];
cell.daysLabel.text = diningHallTimes[indexPath.row][#"days"];
cell.timeLabel.text = diningHallTimes[indexPath.row][#"time"];
return cell;
}
But then this is what my cell looks like
Not sure why this is happening, I am running iOS8, but I need it to work for both is and 7.
Thanks for the help in advance.

Answer 1

You need to calculate boundingRectWithSize: for label text. Also need to calculate number of lines required for updated content also. Try this below method to calculate new frame for label.
- (UILabel *) updateLabelFrame:(UILabel *)label {
CGRect lblRect = label.frame;
CGSize maxSize = CGSizeMake(label.frame.size.width, MAXFLOAT);
CGRect labelRect = [label.text boundingRectWithSize:maxSize options:NSStringDrawingUsesLineFragmentOrigin attributes:#{NSFontAttributeName:label.font} context:nil];
CGFloat labelHeight = labelRect.size.height;
// For below line 16 is default height (The height before content is set). Change this value
// as per your requirement
int lines = labelHeight / 16; // Here 16 is a fix height (default height) for label.
[label setNumberOfLines:lines];
lblRect.size.height = labelHeight;
[label setFrame:lblRect];
return label;
}
Edit:
You can place this method any where you want. Like some base class or in same view controller. Here I modified above method which will return label with dynamic frame.
For your case you need to place this method in view controller class. Then call this method in -cellForRowAtIndexPath after content is updated for label. See below code:
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
DiningInfoTableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:#"Cell" forIndexPath:indexPath];
CGSize constraint = CGSizeMake(CELL_CONTENT_WIDTH - (CELL_CONTENT_MARGIN * 2), 20000.0f);
CGSize size = [diningHallTimes[indexPath.row][#"description"] sizeWithFont:[UIFont systemFontOfSize:FONT_SIZE] constrainedToSize:constraint lineBreakMode:NSLineBreakByWordWrapping];
CGFloat height = MAX(size.height, 44.0f);
CGFloat the = height + (CELL_CONTENT_MARGIN * 2);
cell.descriptionLabel.numberOfLines = 0;
[cell.descriptionLabel setFrame:CGRectMake(20, 0, 280, the)];
NSLog(#"%f", the);
cell.descriptionLabel.text = diningHallTimes[indexPath.row][#"description"];
cell.daysLabel.text = diningHallTimes[indexPath.row][#"days"];
cell.timeLabel.text = diningHallTimes[indexPath.row][#"time"];
// Update descriptionLabel height.
cell.descriptionLabel = [self updateLabelFrame:cell.descriptionLabel];
return cell;
}

You have to set up Autolayout constraints for the label and create a prototype cell with the content. And then you have to return then you have to get the height of the cell.

Try [yourLabel sizeToFit] or you may use [yourLabel sizeThatFit:CGFrame];
