I am trying to use the function sizeToFit. It works perfectly throughout the application however it does not work in the code below. Further to that, if it can't be done the way I am doing it please advise.
self.label = [[UILabel alloc] initWithFrame:CGRectMake(10.0, 67.0, 290, 50)];
self.label.font= [UIFont fontWithName:@"Helvetica-Bold" size:20];
self.label.textColor = [UIColor colorWithRed:33.0f/255.0f green:74.0f/255.0f blue:146.0f/255.0f alpha:1.0f];
self.label.numberOfLines = 0;
self.label.lineBreakMode = NSLineBreakByWordWrapping;
self.label.backgroundColor = [UIColor whiteColor];
[self.contentView addSubview:self.label];
self.description = [[UILabel alloc] initWithFrame:CGRectMake(10.0, 380.0, 300, 400)];
self.description.font= [UIFont fontWithName:@"Helvetica-Light" size:15];
self.description.textColor = [UIColor blackColor];
self.description.textAlignment = NSTextAlignmentJustified;
self.description.numberOfLines = 0;
self.description.lineBreakMode = NSLineBreakByWordWrapping;
self.description.backgroundColor = [UIColor whiteColor];
[self.description sizeToFit];
[self.contentView addSubview:self.description];
self.image = [[UIImageView alloc] initWithFrame:CGRectMake(20, 130, 280, 228)];
self.image.clipsToBounds = YES;
//[scrollView addSubview:self.image];
[self.contentView addSubview:self.image];
self.backgroundColor = [UIColor whiteColor];
I passed the data using this method from a different controller
- (UICollectionViewCell *)collectionView:(UICollectionView *)collectionView cellForItemAtIndexPath:(NSIndexPath *)indexPath
{
Cell *cell=[collectionView dequeueReusableCellWithReuseIdentifier:@"Cell" forIndexPath:indexPath];
NSDictionary *item = [_articleListmain objectAtIndex:indexPath.item];
// set the article image
[cell.image setImageWithURL:[item objectForKey:@"image"]];
[cell.label setText:[item objectForKey:@"title"]];
[cell.description setText:[item objectForKey:@"description"]];
return cell;
}
Since the label is empty, sizeToFit shrinks it down to nothing. That's the point. Set some text then call sizeToFit and the label will be just big enough for the text.
