Hi I am using AFNetworking in my IOS app and I am unable to maintain session. I am using an AFNetworking client and using it in all requests to the server.
I have gone through the following questions: How to manage sessions with AFNetworking , but I don't plan to manipulate the cookies or the session. I intend to implement a session throughout the life cycle of the app.
My AFNetworking client's .m is as follows
@implementation MyApiClient
+(MyApiClient *)sharedClient {
static MyApiClient *_sharedClient = nil;
static dispatch_once_t oncePredicate;
dispatch_once(&oncePredicate, ^{
_sharedClient = [[MyApiClient alloc] initWithBaseURL:[GlobalParams sharedInstance].baseUrl];
});
return _sharedClient;
}
-(id)initWithBaseURL:(NSURL *)url {
self = [super initWithBaseURL:url];
if (!self) {
return nil;
}
[self registerHTTPOperationClass:[AFJSONRequestOperation class]];
[AFJSONRequestOperation addAcceptableContentTypes:[NSSet setWithObject:@"text/html"]];
self.parameterEncoding = AFFormURLParameterEncoding;
return self;
}
@end
and I make the following requests to the server on the call of "- (void)searchBarSearchButtonClicked:(UISearchBar *)search" -->>
NSString *path = [NSString stringWithFormat:@"mobile"];
NSURLRequest *request = [[MyApiClient sharedClient] requestWithMethod:@"GET" path:path parameters:@{@"q":search.text}];
AFJSONRequestOperation *operation = [AFJSONRequestOperation JSONRequestOperationWithRequest:request
success:^(NSURLRequest *request,
NSHTTPURLResponse *response, id json) {
// code for successful return goes here
NSLog(@"search feed %@", json);
search_feed_json = [json objectForKey:@"searchFeed"];
if (search_feed_json.count > 0) {
//<#statements-if-true#>
show_feed_json = search_feed_json;
//reload table view to load the current non-empty activity feed into the table
[self.tableView reloadData];
} else {
//<#statements-if-false#>
NSLog(@"Response: %@", @"no feed");
}
} failure :^(NSURLRequest *request, NSHTTPURLResponse *response, NSError *error, id JSON) {
// code for failed request goes here
NSLog(@"nops : %@", error);
}];
[operation start];
Can anyone please guide me or point out where I am wrong ? Any help would be appreciated. Thanks in advance.
Edit ::
I found my answer in the following post : https://stackoverflow.com/a/14405805/1935921
I initialised the methods listed in the answer in my GlobalParams class, which contains all the Global parameters and methods. I call the "saveCookies" method when the app does the login and the server sends the Cookies. Then these cookies are loaded every time I make any subsequent request by using the method "loadCookies". The Code looks as follows :
GlobalParams.h
#import <Foundation/Foundation.h>
@interface GlobalParams : NSObject
// Your property settings for your variables go here
// here's one example:
@property (nonatomic, assign) NSURL *baseUrl;
// This is the method to access this Singleton class
+ (GlobalParams *)sharedInstance;
- (void)saveCookies;
- (void)loadCookies;
@end
GlobalParams.m
#import "GlobalParams.h"
@implementation GlobalParams
@synthesize myUserData,baseUrl;
+ (GlobalParams *)sharedInstance
{
// the instance of this class is stored here
static GlobalParams *myInstance = nil;
// check to see if an instance already exists
if (nil == dronnaInstance) {
myInstance = [[[self class] alloc] init];
myInstance.baseUrl = [NSURL URLWithString:@"http://www.test.dronna.com/"];
}
// return the instance of this class
return myInstance;
}
- (void)saveCookies{
NSData *cookiesData = [NSKeyedArchiver archivedDataWithRootObject: [[NSHTTPCookieStorage sharedHTTPCookieStorage] cookies]];
NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
[defaults setObject: cookiesData forKey: @"sessionCookies"];
[defaults synchronize];
}
- (void)loadCookies{
NSArray *cookies = [NSKeyedUnarchiver unarchiveObjectWithData: [[NSUserDefaults standardUserDefaults] objectForKey: @"sessionCookies"]];
NSHTTPCookieStorage *cookieStorage = [NSHTTPCookieStorage sharedHTTPCookieStorage];
for (NSHTTPCookie *cookie in cookies){
[cookieStorage setCookie: cookie];
}
}
@end
then I call " [[GlobalParams sharedInstance] saveCookies]; " or " [[GlobalParams sharedInstance] loadCookies]; "(depending on read/write required in cookies) in all my server calls after defining the NSMutableRequest. I hope this helps somebody.
