iOS 开发： 用户名、邮箱、电话号码、密码、昵称正则表达式验证

用户名验证：

+ (BOOL) validateUserName:(NSString *)name

{

NSString *userNameRegex = @"^[A-Za-z0-9]{6,20}+$";

NSPredicate *userNamePredicate = [NSPredicate predicateWithFormat:@"SELF MATCHES %@",userNameRegex];

BOOL B = [userNamePredicate evaluateWithObject:name];

return B;

}

电话号码验证：

+ (BOOL) validateMobile:(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];

return [phoneTest evaluateWithObject:mobile];

}

邮箱验证：

+ (BOOL) validateEmail:(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];

}

密码验证

+ (BOOL) validatePassword:(NSString *)passWord

{

NSString *passWordRegex = @"^[a-zA-Z0-9]{6,20}+$";

NSPredicate *passWordPredicate = [NSPredicate predicateWithFormat:@"SELF MATCHES %@",passWordRegex];

return [passWordPredicate evaluateWithObject:passWord];

}

身份证验证：

+ (BOOL) validateIdentityCard: (NSString *)identityCard

{

BOOL flag;

if (identityCard.length <= 0) {

flag = NO;

return flag;

}

NSString *regex2 = @"^(\\\\d{14}|\\\\d{17})(\\\\d|[xX])$";

NSPredicate *identityCardPredicate = [NSPredicate predicateWithFormat:@"SELF MATCHES %@",regex2];

return [identityCardPredicate evaluateWithObject:identityCard];

}

昵称验证：

+ (BOOL) validateNickname:(NSString *)nickname

{

NSString *nicknameRegex = @"^[\\u4e00-\\u9fa5]{4,8}$";

NSPredicate *passWordPredicate = [NSPredicate predicateWithFormat:@"SELF MATCHES %@",nicknameRegex];

return [passWordPredicate evaluateWithObject:nickname];

}

车牌号验证：

+ (BOOL) validateCarNo:(NSString *)carNo

{

NSString *carRegex = @"^[\\u4e00-\\u9fa5]{1}[a-zA-Z]{1}[a-zA-Z_0-9]{4}[a-zA-Z_0-9_\\u4e00-\\u9fa5]$";

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

NSLog(@"carTest is %@",carTest);

return [carTest evaluateWithObject:carNo];

}

车型验证：

+ (BOOL) validateCarType:(NSString *)CarType

{

NSString *CarTypeRegex = @"^[\\u4E00-\\u9FFF]+$";

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

return [carTest evaluateWithObject:CarType];

}
