用来备份，方便自己使用，需要的拿去

#pragma mark --判断手机号合法性

+ (BOOL)checkPhone:(NSString*)phoneNumber

{

NSString*regex =@"^((13[0-9])|(147)|(15[^4,\\D])|(18[0-9])|(17[0-9]))\\d{8}$";

NSPredicate*pred = [NSPredicatepredicateWithFormat:@"SELF MATCHES %@", regex];

BOOLisMatch = [predevaluateWithObject:phoneNumber];

if(!isMatch)

{

returnNO;

}

returnYES;

}

#pragma mark 判断邮箱

+ (BOOL)checkEmail:(NSString*)email{

//^(\\w)+(\\.\\w+)*@(\\w)+((\\.\\w{2,3}){1,3})$

NSString*regex =@"^[a-zA-Z0-9_-]+@[a-zA-Z0-9_-]+(\\.[a-zA-Z0-9_-]+)+$";

NSPredicate*emailTest = [NSPredicatepredicateWithFormat:@"SELF MATCHES %@", regex];
