Creating dependencies between operations when using AFHTTPRequestOperation - objective-c

Question

I'm working with AFNetworking (2.4.1) in a mac application. I'm hoping to add my own block operation that is for after completion of all of the other operations (which are AFHTTPRequestOperation). I have tried adding dependencies between the completionOperation and the others, but the completionOperation block still executes before the others have completed with success or failure.
A cut down version of the code that illustrates the basics is below. Is anyone able to suggest how to make this work? Thanks.
AFHTTPRequestOperationManager *manager = [[AFHTTPRequestOperationManager alloc] init];
NSBlockOperation *completionOperation = [NSBlockOperation blockOperationWithBlock:^{
NSLog(#"All operations complete");
}];
NSMutableURLRequest *request1 = [[AFHTTPRequestSerializer serializer] requestWithMethod:#"GET" URLString:[[NSURL URLWithString:#"https://api.parse.com/1/classes/SomeClass"] absoluteString] parameters:nil error:nil];
AFHTTPRequestOperation *operation1 = [manager HTTPRequestOperationWithRequest:request1 success:
^(AFHTTPRequestOperation *operation, id responseObject)
{
NSLog(#"operation 1 success");
}
failure:^(AFHTTPRequestOperation *operation, NSError *error)
{
NSLog(#"operation 1 failure");
}];
NSMutableURLRequest *request2 = [[AFHTTPRequestSerializer serializer] requestWithMethod:#"GET" URLString:[[NSURL URLWithString:#"https://api.parse.com/1/classes/OtherClass"] absoluteString] parameters:nil error:nil];
AFHTTPRequestOperation *operation2 = [manager HTTPRequestOperationWithRequest:request2 success:
^(AFHTTPRequestOperation *operation, id responseObject)
{
NSLog(#"operation 2 success");
}
failure:^(AFHTTPRequestOperation *operation, NSError *error)
{
NSLog(#"operation 2 failure");
}];
[completionOperation addDependency:operation1];
[completionOperation addDependency:operation2];
[manager.operationQueue addOperation:operation1];
[manager.operationQueue addOperation:operation2];
[manager.operationQueue addOperation:completionOperation];

- (void) test3:(void (^)(AFHTTPRequestOperation *operation, id responseObject))success
failure:(void (^)(AFHTTPRequestOperation *operation, NSError *error))failure
{
// block 1
NSString *string = [NSString stringWithFormat:#"%#weather.php?format=json", BaseURLString];
NSURL *urll = [NSURL URLWithString:string];
NSURLRequest *request = [NSURLRequest requestWithURL:urll];
AFHTTPRequestOperation *operation = [[AFHTTPRequestOperation alloc] initWithRequest:request];
operation.responseSerializer = [AFJSONResponseSerializer serializer];
[operation setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) {
NSLog(#"OPERATION 1 %#",responseObject );
test_Sync = #"done";
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
test_Sync = #"faile"; }];
//block 2
NSString *string2 = [NSString stringWithFormat:#"%#weather.php?format=json", BaseURLString];
NSURL *urll2 = [NSURL URLWithString:string2];
NSURLRequest *request2 = [NSURLRequest requestWithURL:urll2];
AFHTTPRequestOperation *operation2 = [[AFHTTPRequestOperation alloc] initWithRequest:request2];
[operation2 setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation2, id responseObject) {
// Print the response body in text
NSLog(#"Response: OPERATION 2 %#", [[NSString alloc] initWithData:responseObject encoding:NSUTF8StringEncoding]);
} failure:^(AFHTTPRequestOperation *operation2, NSError *error) {
NSLog(#"Error: %#", error);
}];
// Add the operation to a queue
// It will start once added
NSOperationQueue *operationQueue = [[NSOperationQueue alloc] init];
// Make operation2 depend on operation1
[operation addDependency:operation2];
[operationQueue addOperations:#[operation, operation2] waitUntilFinished:YES];
}
