ios-vcf格式通讯录的生成和解析（开源），支持5.0以下版本

最近研究通讯录同步，做过vcf的亲们都应该知道，苹果5.0之后才推出两个api ： ABPersonCreateVCardRepresentationWithPeople 和 ABPersonCreatePeopleInSourceWithVCardRepresentation，但是要某些变态客户要求产品支持4.3的系统（比如我们的大boss），所以我们就必须自己生成和解析vcf文件啦。不熟悉vcf格式的亲们自己问度娘~

话不多说，璐爷我找了枪手帮我写了份代码，自己用了挺好，在此开源分享给大家吧，以下为原创，转载请说明，谢啦~ 以下为一个非常简单demo的.m文件，需要此demo的亲们密我，传给你~

       if(filePath) {

        [self loadVCF:filePath];
