how to communicate with server with afnetworking? - ios

Question

I am using AFNetworking Please take a look at my code
+(void)requestLogin:(id<LoginRequestDelegate>) delegate LoginURL:(NSString *)loginurl{
static User *user;
static id <LoginRequestDelegate> del;
del=delegate;
static AFHTTPRequestOperation *afRequest;
if(afRequest){
return;
}
isLogin = NO;
Reachability *objInternetReachable = [Reachability reachabilityForInternetConnection];
NetworkStatus status = [objInternetReachable currentReachabilityStatus];
if(status != NotReachable) {
NSString *strUrl=loginurl;
NSLog(#"Login JSON URL %#", strUrl);
strUrl=[strUrl stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
NSURLRequest *urlReq=[[NSURLRequest alloc] initWithURL:[NSURL URLWithString:strUrl] cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:60.0];
afRequest=[[AFHTTPRequestOperation alloc] initWithRequest:urlReq];
AFNetworkActivityIndicatorManager * newactivity = [[AFNetworkActivityIndicatorManager alloc] init];
newactivity.enabled = YES;
[afRequest setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) {
newactivity.enabled = NO;
NSString *strRes=[[NSString alloc] initWithData:responseObject encoding:NSASCIIStringEncoding];
//JSON DATA
NSDictionary *dic=[[NSDictionary alloc]init];
SBJsonParser *parser=[[SBJsonParser alloc] init];
dic=[parser objectWithString:strRes];
NSLog(#"Dic :- %#", dic);
if(dic){
NSString *isLoginRes = [dic objectForKey:#"login"];
if([isLoginRes isEqualToString:#"true"]){
NSLog(#"login res %#",isLoginRes);
isLogin = YES;
NSDictionary *resp = [dic objectForKey:#"resp"];
user = [User sharedInstance];
// User
NSDictionary *userDic = [resp objectForKey:#"User"];
user.userId = [userDic objectForKey:#"id"];
user.userEmail = [userDic objectForKey:#"email"];
I am using this piece of code, but when i reach on this method it jump to failure block.
[afRequest setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject)
This block is not executed.
The program moves jump on this block
failure:^(AFHTTPRequestOperation *operation, NSError *error) {
newactivity.enabled = NO;
if(del){
[del isLoginRespomce:isLogin LoginDetail:user];
}

Your code could be much simpler, use for the AFNetworking stuff the AFHTTPRequestOperationManager, it's really easy to use and works just as good as allocating your own AFHTTPRequestOperation etc.
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
[manager GET:loginurl parameters:nil success:^(AFHTTPRequestOperation *operation, id responseObject) {
NSLog(#"JSON: %#", responseObject);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(#"Error: %#", error);
}];
