iOS开发判断输入的是否为手机号、邮箱、车牌号

手机号的判断：

+ (BOOL)isMobileNumber:(NSString *)mobileNum

{

    NSString *pattern = @"^1+[34578]+\\d{9}";

    NSPredicate *pred = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", pattern];

    BOOL isMatch = [pred evaluateWithObject:mobileNum];

    return isMatch;

}

邮箱的判断：

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

    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:email];

}

车牌号的判断

+(BOOL)isValidateCar:(NSString *)car{

    NSString *carRegex = @"^[A-Za-z]{1}[A-Za-z_0-9]{5}$";

    NSPredicate *carTest = [NSPredicate predicateWithFormat:@"SELF MATCHES %@",carRegex];

    NSLog(@"carTest is %@",carTest);

    return [carTest evaluateWithObject:car];

}
