检测邮箱有效,及手机号码的一些方法

1.验证输入的是否是11位合格的手机号

- (BOOL)isMobileNumber:(NSString *)mobileNum
{
    NSString *regex = @"^((13[0-9])|(147)|(15[^4,\\D])|(18[0,5-9]))\\d{8}$";
    NSPredicate *pred = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", regex];
    BOOL isMatch = [pred evaluateWithObject:mobileNum];
    return YES;
}

2.检测邮箱是否合法

#pragma mark ----检测邮箱是否合法
- (BOOL)validateEmail: (NSString *) candidate {
    NSString *emailRegex = @"[A-Z0-9a-z._%+-]+@[A-Za-z0-9.-]+\\.[A-Za-z]{2,4}";
    NSPredicate *emailTest = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", emailRegex];
    return [emailTest evaluateWithObject:candidate];
}

3.正则判断手机号码地址格式

// 正则判断手机号码地址格式
- (NSString *)isMobileNumber:(NSString *)mobileNum
{
    /**
     * 手机号码
     * 移动：134[0-8],135,136,137,138,139,150,151,157,158,159,182,187,188

     */
    NSString * MOBILE = @"^1(3[0-9]|5[0-35-9]|8[025-9])\\d{8}$";

    NSString * CU = @"^1(3[0-2]|5[256]|8[56])\\d{8}$";
    /**

     22         */
    NSString * CT = @"^1((33|53|8[09])[0-9]|349)\\d{7}$";
    /**
