Facebook Graph API for iOS search - iphone

Question

I am trying to search places from the GraphAPI using following code without luck. Can anybody please enlight my path ?
If I try to post link/message/photo it works as expected but when trying to get location it always fails and gives me **The operation couldn’t be completed. (facebookErrDomain error 10000.)**
//Following statement is using permissions
NSArray * permissions = [NSArray arrayWithObjects:#"publish_stream",#"user_checkins", #"friends_checkins", #"publish_checkins", nil];
[facebook authorize:FB_APP_ID permissions:permissions delegate:_delegate];
NSString *centerString = [NSString stringWithFormat: #"%f,%f", 37.76,-122.427];
NSString *graphPath = #"search";
NSMutableDictionary *params = [NSMutableDictionary dictionaryWithObjectsAndKeys:
#"coffee",#"q",
#"place",#"type",
centerString,#"center",
#"1000",#"distance", // In Meters (1000m = 0.62mi)
nil];
[facebook requestWithGraphPath:_path andParams:_params andHttpMethod:#"POST" andDelegate:_delegate];

Answer 1

Never mind. Downloaded latest sample HackBook from facebook for graph api from github and it includes sample code for the same.

Answer 2

For "search" you should use "GET" instead of "POST".
https://developers.facebook.com/docs/graph-api/using-graph-api/v2.2#search
With Facebook iOS SDK, you can use FBRequestConnection after login.
[FBRequestConnection startWithGraphPath:#"search?q=coffee&type=place&center=37.76,-122.427&distance=1000"
completionHandler:^(FBRequestConnection *connection, id result, NSError *error) {
if (!error) {
// Sucess! Include your code to handle the results here
NSLog(#"result: %#", result);
} else {
// An error occurred, we need to handle the error
// See: https://developers.facebook.com/docs/ios/errors
NSLog(#"error: %#", error);
}
}];

With Last SDK
NSMutableDictionary *params2 = [NSMutableDictionary dictionaryWithCapacity:3L];
[params2 setObject:#"37.416382,-122.152659" forKey:#"center"];
[params2 setObject:#"place" forKey:#"type"];
[params2 setObject:#"1000" forKey:#"distance"];
[[[FBSDKGraphRequest alloc] initWithGraphPath:#"/search" parameters:params2 HTTPMethod:#"GET"] startWithCompletionHandler:^(FBSDKGraphRequestConnection *connection, id result, NSError *error) {
NSLog(#"RESPONSE!!! /search");
NSLog(#"result %#",result);
NSLog(#"error %#",error);
}];
