Use this method to find lable truncated in iOS 7.

- (BOOL)isTruncated:(UILabel *)label{
        CGSize sizeOfText = [label.text boundingRectWithSize: CGSizeMake(label.bounds.size.width, CGFLOAT_MAX)
                                                     options: (NSStringDrawingUsesLineFragmentOrigin|NSStringDrawingUsesFontLeading)
                                                  attributes: [NSDictionary dictionaryWithObject:label.font forKey:NSFontAttributeName] context: nil].size;

        if (self.frame.size.height < ceilf(sizeOfText.height)) {
            return YES;
        }
        return NO;
    }
