How can I add Status code to an Error? - ios

Question

I have a 'JSON' data with different status codes, as shown in the image, I'm using 'AFHTTPSessionManager', And if we call the API I get 200 as success code, Apart from that in my response object I have status codes So I want to do different operations based on the status codes, For this I have written code like this..
-(void)validateOTP:(NSString *)OTP andUserID:(NSString *)userID withCompletion:(void(^)(NSDictionary* dictionary, NSError* error))completion
{
UTValidateOTPRequest *request = [UTValidateOTPRequest validateOTPRequestWithOTP:OTP andUserID:userID];
NSDictionary *paramDict = [request dictionaryRepresentation];
NSURLSessionDataTask *task = [self postRequestToResouce:[NSString stringWithFormat:#"%#/ValidateOTP",kServerCommonEndPoint] arguments:paramDict successHandler:^(NSDictionary *response) {
NSNumber *statusCode = response[kStatusCodeKey];
if (statusCode.integerValue == UTStatusCodeSuccess) {
completion(response, nil);
}
else {
NSError *error = [NSError mapStatusCodeToError:statusCode.integerValue details:response];
completion(nil, error);
}
} errorHandler:^(NSError *error) {
NSError *newError = [NSError mapStatusCodeToError:error.code details:error.userInfo];
completion(nil, newError);
}];
[self addDataTask:task];
}
As you can see, even inside success handler I'm passing error and calling a category method we have created.
NSError *error = [NSError mapStatusCodeToError:statusCode.integerValue details:response];
This method implemented as follows
+ (NSError *)mapStatusCodeToError: (NSInteger)statusCode details:(NSDictionary*) errorInfo
{
NSString *bundleIdentifier = [[NSBundle mainBundle] bundleIdentifier];
NSString *domain = [bundleIdentifier stringByAppendingString:kErrorDomainKey];
NSString *errorMessage = nil;
if (errorInfo[kErrorMessageKey] && ![errorInfo[kErrorMessageKey] isEqualToString:kEmptyString]) {
errorMessage = errorInfo[kErrorMessageKey];
}
else{
// use common message
errorMessage = kInternetNotAvailableMessage;
}
NSDictionary *userInfo = #{NSLocalizedDescriptionKey:NSLocalizedString(errorMessage, nil)};
NSLog(#"User INFO : %#",userInfo);
NSError *internetUnavailableError = [NSError errorWithDomain:domain
code:NSURLErrorNotConnectedToInternet
userInfo:userInfo];
NSLog(#"Error Code : %ld",(long)internetUnavailableError.code);
return internetUnavailableError;
}
Here I want to use the statusCode that I'm passing as parameter to this method so that I can get that status code where I'm calling this method
[[UTServerManager sharedInstance] validateOTP:self.enterOTPText.text andUserID:self.userId withCompletion:^(NSDictionary *dictionary, NSError *error) {
// Here I want to get the status code of error not like -1009 , but what ever statusCode that I'm getting from the API response.
}];
So in this method can I get the response status code if it is not success code means as you see in the image in the first response is success and remaining are error responses.
And I know that I can use the statusCode in the category method but I dont know how to use it, If I store this status-Code in the category method for error as above , that I'm passing as a parameter to the methods then I can call them where ever I require How to get this ?
And my restriction is I should these methods only but I have to add the response status code to error ??

Looks like you are passing a userInfo dict to the NSError. You could add to this dictionary prior to creating the NSError you are returning, and then later it would be available in the NSError callback.
