How to use the result of FBSDKGraphRequest Outside the Block - ios

Question

I am designing an application which uses Facebook to display the feeds in a table view ..so in order to get the result of the feeds i have called a method FBSDKGraphRequest but I do not know how to retrieve the values of the results from FBSDKGraphRequest outside since they are located in a completion block.I want to display the name and message in the table view....
The code illustration is below:-
FBSDKGraphRequest *request = [[FBSDKGraphRequest alloc]initWithGraphPath:Path parameters:#{ #"fields": #"feed{from,message,created_time}",} tokenString:accessToken version:FBSDK_TARGET_PLATFORM_VERSION HTTPMethod:#"GET"];
[request startWithCompletionHandler:^(FBSDKGraphRequestConnection *connection, id result, NSError *error) {
if(error)
NSLog(#"No Data");
else {
FeedCount = [NSDictionary dictionaryWithDictionary:result];
NSDictionary*feed = [FeedCount objectForKey:#"feed"];
NSArray*array1 = [feed objectForKey:#"data"];
NSArray*array3 = [array1 valueForKey:#"from"];
NSLog(#"Data:%#",array3); ---------------> **Displaying Data**
}
}];
NSLog(#"FeedCount:%#",FeedCount);----------------->**Showing Null**
Any help will be Appreciated

To get the result of dictionary from fbsdk please declare variable as __block NSDictionary *json;
Then assign this inside block like,
json =[FeedCount objectForKey:#"feed"];
Did you try this like,
__block NSDictionary *json;
FBSDKGraphRequest *request = [[FBSDKGraphRequest alloc]initWithGraphPath:Path parameters:#{ #"fields": #"feed{from,message,created_time}",} tokenString:accessToken version:FBSDK_TARGET_PLATFORM_VERSION HTTPMethod:#"GET"];
[request startWithCompletionHandler:^(FBSDKGraphRequestConnection *connection, id result, NSError *error) {
if(error)
NSLog(#"No Data");
else {
FeedCount = [NSDictionary dictionaryWithDictionary:result];
json = [FeedCount objectForKey:#"feed"];
NSArray*array1 = [feed objectForKey:#"data"];
NSArray*array3 = [array1 valueForKey:#"from"];
NSLog(#"Data:%#",array3); ---------------> **Displaying Data**
}
}];
NSLog(#"json:%#",json);
