NSString sizeWithFont: alternative in iOS7

Question

The method (sizeWithFont: forWidth: lineBreakMode:) was deprecated in iOS 7.0.

But how can I do a same thing like following code in iOS 7.0?

Answer 1

For those who want the height with width function but in swift its:

func HeigthWithWidth(stringToSize : String, width : CGFloat, font : UIFont) -> CGFloat {
    var attrStr = NSMutableAttributedString(string: stringToSize);
    attrStr.addAttribute(NSFontAttributeName, value: font, range: NSRange.init(location: 0, length: stringToSize.characters.count));
    var rect = attrStr.boundingRectWithSize(CGSize(width: width, height: CGFloat.max), options: [NSStringDrawingOptions.UsesLineFragmentOrigin, NSStringDrawingOptions.UsesFontLeading], context: nil);
    return rect.size.height;
}

Hope that helps those who come looking later

Answer 2

I have got a category for NSString to get the width or heigth of a string:

- (CGFloat)widthWithFont:(UIFont *)font
{
    NSDictionary *attributes = [NSDictionary dictionaryWithObjectsAndKeys:font, NSFontAttributeName, nil];
    return [[[NSAttributedString alloc] initWithString:self attributes:attributes] size].width;
}

- (CGFloat)heigthWithWidth:(CGFloat)width andFont:(UIFont *)font
{
    NSMutableAttributedString *attrStr = [[NSMutableAttributedString alloc] initWithString:self];
    [attrStr addAttribute:NSFontAttributeName value:font range:NSMakeRange(0, [self length])];
    CGRect rect = [attrStr boundingRectWithSize:CGSizeMake(width, CGFLOAT_MAX) options:NSStringDrawingUsesLineFragmentOrigin | NSStringDrawingUsesFontLeading context:nil];
    return rect.size.height;
}
