Answer 1

This method will give perfect height

-(float) getHeightForText:(NSString*) text withFont:(UIFont*) font andWidth:(float) width{
CGSize constraint = CGSizeMake(width , 20000.0f);
CGSize title_size;
float totalHeight;


title_size = [text boundingRectWithSize:constraint
                                options:NSStringDrawingUsesLineFragmentOrigin
                             attributes:@{ NSFontAttributeName : font }
                                context:nil].size;

totalHeight = ceil(title_size.height);

CGFloat height = MAX(totalHeight, 40.0f);
return height;
}
