Try this,

UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, 100, 35)];//set the correct width here
NSString *text = @"A string of x letters of text goes here";
label.text = text;
CGSize constrainedSize = CGSizeMake(label.frame.size.width  , 9999);

//TODO:change the font properties to yourown
NSDictionary *attributesDictionary = [NSDictionary dictionaryWithObjectsAndKeys:
                                      [UIFont fontWithName:@"HelveticaNeue" size:11.0], NSFontAttributeName,
                                      nil];

NSMutableAttributedString *string = [[NSMutableAttributedString alloc] initWithString:text attributes:attributesDictionary];

CGRect requiredHeight = [string boundingRectWithSize:constrainedSize options:NSStringDrawingUsesLineFragmentOrigin context:nil];

if (requiredHeight.size.width > label.frame.size.width) {
    requiredHeight = CGRectMake(0,0, label.frame.size.width, requiredHeight.size.height);
}
CGRect newFrame = label.frame;
newFrame.size.height = requiredHeight.size.height;
label.frame = newFrame;

If you are using auto layouts. Just set the numberOflines = 0 . Note : Do not pin the hight of the label.Based on the other constraints it will automatically grow its size to fit the string.
