AGSQueryTaskDelegate not firing

[NicoleDe_La_Feld]

I am trying to query all the features from my database through a querytask, but no delegate methods are being invoked.
I created a strong property AGSQueryTask :

@interface MyClass : NSObject <AGSQueryTaskDelegate> 

@property(nonatomic, strong)AGSQueryTask* queryTask;

set the delegate as self:

 self.queryTask.delegate = self;

but nothing happens.
Ideas?

sorry if i'm misunderstand your question but you'll need to set up a query to excecute your query task. Here is a simplified example.

//alongside your agsquerytask set up an agsquery
@property(nonatomic, strong)AGSQueryTask* queryTask;
@property(nonatomic, strong)AGSQuery* query;

after setting up that query, maybe in viewDidLoad or wherever you'd like the query to happen you'll need to do something like this.

//set up query task
self.queryTask = [AGSQueryTask queryTaskWithURL:[NSURL URLWithString: "your URL"]]; 
self.queryTask.delegate = self; 

//set up query and options
self.query = [AGSQuery query]; 
self.query.outFields = [NSArray arrayWithObjects: "*", nil]; 
self.query.where = @"1=1";

//execute querytask with query 
[self.queryTask executeWithQuery: self.query];

with that in place you should reach
queryTask operation didExecuteWithFeatureSetResult retreivedFeatureSet
where you will have access to whatever was returned from your query.

Hope this helps.

Thank you for your answer. I already did what you say and it's right.
The problem was that I accidentally deallocated the queryTask before the operation was completed.
