boundingRectWithSize gives height with truncated text - ios

Question

I am using the following method to determine the height required to display the text that i have. However i cannot get the correct height without truncating the text at the end.
CGRect labelRect = [comment boundingRectWithSize:headerMax
options:NSStringDrawingUsesLineFragmentOrigin |
NSStringDrawingUsesFontLeading
attributes:#{NSFontAttributeName:font}
context:nil];
How can i say not to determine the required label height without truncating the text at the end. I want the whole text to fit into the label.

Answer 1

-(CGRect)getLabelSizeWithText:(NSString *)textLabel forFontSize:(CGFloat) fontSize
{
CGRect textRect;
if (textLabel != nil)
{
NSAttributedString *actualString = [[NSAttributedString alloc] initWithString:textLabel attributes:#{NSFontAttributeName:[UIFont fontWithName:#"HelveticaNeue" size:fontSize]} ];
NSStringDrawingContext *targetContext = [[NSStringDrawingContext alloc] init];
CGFloat commentLabelWidth = [[UIScreen mainScreen]bounds].size.width;
textRect = [actualString boundingRectWithSize:CGSizeMake(commentLabelWidth, 900) options:NSStringDrawingUsesLineFragmentOrigin context:targetContext];
}
return textRect;
}
This one should work. Try it

Use -
1. If you want word wrap -
labelView.lineBreakMode = NSLineBreakByWordWrapping;
labelView.numberOfLines = 2;
CGRect labelRect = [comment boundingRectWithSize:headerMax
options:NSStringDrawingUsesLineFragmentOrigin |
NSStringDrawingUsesFontLeading | NSLineBreakByWordWrapping
attributes:#{NSFontAttributeName:font}
context:nil];
2. If you Don't want truncating tail at all -
// No line break mode
labelView.numberOfLines = 0;
CGRect labelRect = [comment boundingRectWithSize:headerMax
options:NSStringDrawingUsesLineFragmentOrigin |
NSStringDrawingUsesFontLeading
attributes:#{NSFontAttributeName:font}
context:nil];

Answer 3

Try this
 
NSString *cellText = restaurant.review;
UIFont *cellFont = [UIFont systemFontOfSize:14.0];
NSDictionary *attributes = #{NSFontAttributeName: cellFont};
CGRect labelSize = [cellText boundingRectWithSize:CGSizeMake([UIScreen mainScreen].bounds.size.width-20, CGFLOAT_MAX) options:NSStringDrawingUsesLineFragmentOrigin attributes:attributes context:nil];

I am not really sure whether I understood your question correctly; it sounds like you are trying to calculate the frame size needed to display the text and setting the frame manually with that. Additionally, by setting .numberOfLines = 2, you are limiting the text that you can show. My suggestion would be for you to set up constraints via autolayout, optionally add a .minimumScaleFactor and let it dynamically resize itself.
If you still want to calculate size, with numberOfLines taken into consideration, you can use a prototype label and have use its height
- (CGSize)preferredSizeForString:(NSString *)string
width:(CGFloat)width
{
UILabel *prototypelabel = [UILabel new];
prototypelabel.frame = CGRectMake(0, 0, width, 0);
prototypelabel.text = #"Your string";
prototypelabel.numberOfLines = 2;
[prototypelabel sizeToFit];
return prototypelabel.frame.size;
}
