在某些App应用里面需要填写用户信息(用于验证),有身份证、手机号、军官证等等。下面来跟大家分享一下各自的验证方式。
1.验证 手机号码 ,这个是对任意输入的一串数字做验证,返回一个识别结果(字符串),根据这个结果再做判断。

//判断手机号码

*/
NSString *CM_NUM = @ "^((13[4-9])|(147)|(15[0-2,7-9])|(178)|(18[2-4,7-8]))\\d{8}|(1705)\\d{7}$" ;

/** 银行卡号有效性问题Luhn算法
* 现行 16 位银联卡现行卡号开头 6 位是 622126~622925 之间的,7 到 15 位是银行自定义的,
* 可能是发卡分行,发卡网点,发卡序号,第 16 位是校验码。
* 16 位卡号校验位采用 Luhm 校验方法计算:
* 1,将未带校验位的 15 位卡号从右依次编号 1 到 15,位于奇数位号上的数字乘以 2
* 2,将奇位乘积的个十位全部相加,再加上所有偶数位上的数字
* 3,将加法和加上校验位能被 10 整除。
