Dynamic set height of label

There are so many occassions when we have to set height of the label according to text displayed in label or textview etc.

NSString *text  = @"A fairy tale is a type of short story that typically features folkloric fantasy characters, such as fairies, goblins, elves, trolls, dwarves, giants,mermaids, or gnomes, and usually magic or enchantments. Fairy tales may be distinguished from other folk narratives such as legends (which generally involve belief in the veracity of the events described) and explicitly moral tales, including beast fables."

CGSize textViewSize;

textViewSize = [text sizeWithFont:[UIFont fontWithName:@"Helvetica Neue" size:14.0]

                                   constrainedToSize:CGSizeMake(246, FLT_MAX)

                                       lineBreakMode:UILineBreakModeCharacterWrap];

 [geographics_lbl setFrame:CGRectMake(x, y, 246, roundf(textViewSize.height))];
