Trouble filling out the whole body text field

My Body Label text field is only displaying one line of text. I'm not sure if when you input text if it matters if you input a newline into the text. Or if it's supposed to just automatically word wrap your input. I have this in my EntryCell.m

• (CGFloat)heightForEntry:(DiaryEntry *)entry { const CGFloat topMargin = 35.0f; const CGFloat bottomMargin = 80.0f; const CGFloat minHeight = 106.0f;

  UIFont *font = [UIFont systemFontOfSize:[UIFont systemFontSize]];

  CGRect boundingBox = [entry.body boundingRectWithSize:CGSizeMake(202, CGFLOAT_MAX) options:(NSStringDrawingUsesFontLeading | NSStringDrawingUsesLineFragmentOrigin) attributes:@{NSFontAttributeName: font} context:nil];

  return MAX(minHeight, CGRectGetHeight(boundingBox) + topMargin + bottomMargin); }
