【代码笔记】iOS-验证手机号，邮箱，车牌号是否合法

一，代码。

- (void)viewDidLoad
{
    [super viewDidLoad];
    // Do any additional setup after loading the view.

    NSLog(@"------%d------",[self isValidateEmail:@"12345"]);
    NSLog(@"------%d------",[self isValidateMobile:@"12345"]);
    NSLog(@"---%d---------",[self isValidateCar:@"12345"]);

}

#pragma -mark -邮箱验证
-(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];
}

#pragma -mark -手机号码验证
-(BOOL) isValidateMobile:(NSString *)mobile
{
    //手机号以13， 15，18开头，八个 \d 数字字符
    NSString *phoneRegex = @"^((13[0-9])|(15[^4,\\D])|(18[0,0-9]))\\d{8}$";
    NSPredicate *phoneTest = [NSPredicate predicateWithFormat:@"SELF MATCHES %@",phoneRegex];
    //    NSLog(@"phoneTest is %@",phoneTest);
    return [phoneTest evaluateWithObject:mobile];
}

#pragma -mark -车牌号验证
-(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];
}

二，输出。
