Iterating over AFHTTPSessionManager while in background mode












0














I am using AFHTTPSessionManager to retrieve information from an API multiple times. It works correctly when its not in background mode, though once the app is closed AFHTTPSessionManager call doesn't seem to want to work, it blocks.



-(void)requestGET:(NSString *)strURL xml:(BOOL)xml Token:(NSString *)token success:(void (^)(NSDictionary *responseObject))success failure:(void (^)(NSError *error))failure {

BOOL isNetworkAvailable = [self checkNetConnection];

if (!isNetworkAvailable) {
NSLog(@"No connection");
[self showAlert:@"Please check your internet connection"];
return;
}else{

AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
[manager.requestSerializer setValue:[NSString stringWithFormat:@"Bearer %@",token] forHTTPHeaderField:@"Authorization"];

if(xml){
// Content xml
manager.responseSerializer = [AFHTTPResponseSerializer new];
manager.responseSerializer.acceptableContentTypes = [NSSet setWithObjects:@"application/vnd.garmin.tcx+xml", nil];
}else{
// Content json
manager.responseSerializer.acceptableContentTypes = [NSSet setWithObjects:@"application/json", nil];
}

[manager GET:strURL parameters:nil progress:nil success:^(NSURLSessionDataTask * _Nonnull task, id _Nullable responseObject) {
if([responseObject isKindOfClass:[NSDictionary class]]) {
// Return json
if(success) {
success(responseObject);
}
}else{
// Return xml to nsdictionary
if(success){
NSString* responseStr = [[NSString alloc] initWithData:responseObject encoding:NSUTF8StringEncoding];
NSDictionary * XMLDictionary = [XMLReader dictionaryForXMLString:responseStr error:nil];
success(XMLDictionary);
}
}
} failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
NSLog(@"%@", error);
if(failure) {
failure(error);
}
}];
}
}


The above method is called below multiple times to grab the data from the API and pump it out.



-(void)getFitbitURL{

// Create group
dispatch_group_t group = dispatch_group_create();

// Retrieve array
NSMutableArray *URLS = [self generateURLS];
for (NSMutableArray *entity in URLS){

NSString *url = entity[0];

// Enter group
dispatch_group_enter(group);

NSString *token = [FitbitAuthHandler getToken];
FitbitAPIManager *manager = [FitbitAPIManager sharedManager];

// Get URL
[manager requestGET:url xml:0 Token:token success:^(NSDictionary *responseObject) {

// Do stuff with output
printf("%s",[[responseObject description]UTF8String]);

// Leave group
dispatch_group_leave(group);

} failure:^(NSError *error) {
NSLog("%@",error);

// Leave group
dispatch_group_leave(group);
}];
}

// Wait for all of group to complete
dispatch_group_notify(group, dispatch_get_main_queue(), ^{
NSLog(@"Complete");
});
}


I have tried to research on the internet how to do this but all my ideas have failed, my applicationDidEnterBackground method works correctly when the app closes but everything else doesn't work correctly, such as the url requests. Any suggestions would be appreciated
.
