I'm struggling with how to dynamically size a uilabel inside a uitableviewcell and also to adjust the height of the table cell depending on the text I put into the label. I want to display a string in its entirety within the tableview cell, always at the same font size for all cells. This seems pretty standard, but I notice a lot of discussion/debate/discontent on stackoverflow. I got started with these posts:
Resize Custom cell with a UILabel on it based on content text from JSON file (@Seya's answer) boundingRectWithSize for NSAttributedString returning wrong size (@JOM's answer)
The functions I'm trying to use are copies of what Seya did, barely modified. However, I am seeing that although the function prints out different heights for different cells, all I am seeing is 1 line of text per label even though they should show many lines. Also, strangely the text from one cell seems to display on top of another cell - not sure whether this is related.
My 2 questions: (1) Why do I only see the first line of text? (2) Why is the UILabel/cell not resizing per the different heights I see printed out in the log (or are they resizing but masked by issue #1)?
Here's the three functions I'm using (these along with a xib - could the xib be the problem?):
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
JudgeCell *cell = [tableView dequeueReusableCellWithIdentifier:@"JudgeCell"];
if(!cell)
{
[tableView registerNib:[UINib nibWithNibName:@"JudgeCell" bundle:nil] forCellReuseIdentifier:@"JudgeCell"];
cell = [tableView dequeueReusableCellWithIdentifier:@"JudgeCell"];
}
cell.username.text = self.object.answerUser[indexPath.row];
cell.answer.text = self.object.answerArray[indexPath.row];
NSString *text = cell.answer.text;
CGSize constraint = CGSizeMake(50, 20000.0f);
CGSize size = [self frameForText:text sizeWithFont:[UIFont systemFontOfSize:15] constrainedToSize:constraint];
cell.username.frame = CGRectMake(10, 10, 50, size.height); //MAX(size.height, 14.0f));
return cell;
}
-(CGSize)frameForText:(NSString*)text sizeWithFont:(UIFont*)font constrainedToSize:(CGSize)size {
NSMutableParagraphStyle * paragraphStyle = [[NSMutableParagraphStyle defaultParagraphStyle] mutableCopy];
paragraphStyle.lineBreakMode = NSLineBreakByCharWrapping;
NSDictionary * attributes = @{NSFontAttributeName:font,
NSParagraphStyleAttributeName:paragraphStyle
};
CGRect textRect = [text boundingRectWithSize:size
options:(NSStringDrawingUsesLineFragmentOrigin|NSStringDrawingUsesFontLeading)
attributes:attributes
context:nil];
NSLog(@"size is %f ", textRect.size.height);
return textRect.size;
}
- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath;
{
NSString *text = self.object.answerArray[indexPath.row];
CGSize constraint = CGSizeMake(50, 20000.0f);
CGSize size = [self frameForText:text sizeWithFont:[UIFont systemFontOfSize:15] constrainedToSize:constraint];
CGFloat height = size.height; //MAX(size.height, 14.0f);
NSLog(@"size is %f AT INDEX %d", height, indexPath.row);
return height + 20;
}
Thanks for any advice!
