常用的正则表达式-身份证，密码，手机号，邮箱，昵称等

第一步：首先验证是否是可用的正则

+(BOOL)isValidateRegularExpression:(Nsstring *)strDestination byExpression:(Nsstring *)strExpression
{

nspredicate *predicate = [nspredicate predicateWithFormat:@"SELF MATCHES %@",strExpression];

return [predicate evaluateWithObject:strDestination];

}
//验证email
+(BOOL)isValidateEmail:(Nsstring *)email {

Nsstring *strRegex = @"[A-Z0-9a-z._%+-]+@[A-Za-z0-9.-]+\\.[A-Za-z]{1,5}";

BOOL rt = [self isValidateRegularExpression:email byExpression:strRegex];

return rt;
