How to post location with image to facebook in IOS? - ios

Question

I am trying to share location along with image to facebook. I have successfully shared image but unable to share location. Below is my code of sharing image.
UIImage *facebookImage = [UIImage imageWithData:[NSData dataWithContentsOfURL:[NSURL URLWithString:[NSString stringWithFormat:#"%#%#",imagesURL,str]]]];
NSMutableDictionary* params = [[NSMutableDictionary alloc] init];
[params setObject:#"New Happening created on the HappenShare mobile app." forKey:#"message"];
[params setObject:facebookImage forKey:#"picture"];
[FBRequestConnection startWithGraphPath:#"me/photos" parameters:params HTTPMethod:#"POST" completionHandler:^(FBRequestConnection *connection,id result,NSError *error)
{
if (error)
{
NSLog(#"error : %#",error);
}
else
{
NSLog(#"Result : %#",result);
}
}];
Now for sharing location what parameter should I add in above code. I am attaching an image also to understand better that how the shared location will look like.Below image shows that how the image with text will indicate a location into map. Please suggest me a solution for that.

Answer 1

Along with "message" and you also need "place" ID to post as param.
Request for a "publish_actions" so that you can post a place/location.
Below is the code i've used:
NSMutableDictionary *params = [NSMutableDictionary dictionary];
[params setObject:#"Hello World" forKey:#"message"];
[params setObject:#"110503255682430"/*sample place id*/ forKey:#"place"];
[[[FBSDKGraphRequest alloc] initWithGraphPath:#"/me/feed" parameters:params HTTPMethod:#"POST"] startWithCompletionHandler:^(FBSDKGraphRequestConnection *connection, id result, NSError *error) {
NSLog(#"result %#",result);
NSLog(#"error %#",error);
}];
You can also check this with the "administrator/tester" accounts given in Developer page -> your app -> Roles.
Use Graph explorer for better practice:
https://developers.facebook.com/tools/explorer/108895529478793?method=POST&path=me%2Ffeed%3F&version=v2.5&message=Hello%20world&place=110503255682430
Below code may help you in getting place id near your location:
NSMutableDictionary *params2 = [NSMutableDictionary dictionaryWithCapacity:4L];
[params2 setObject:[NSString stringWithFormat:#"%#,%#",YourLocation latitude,YourLocation longitude] forKey:#"center"]; //Hard code coordinates for test
[params2 setObject:#"place" forKey:#"type"];
[params2 setObject:#"100"/*meters*/ forKey:#"distance"];
[[[FBSDKGraphRequest alloc] initWithGraphPath:#"/search" parameters:params2 HTTPMethod:#"GET"] startWithCompletionHandler:^(FBSDKGraphRequestConnection *connection, id result, NSError *error) {
NSLog(#"RESPONSE!!! /search");
}];
OR
[[[FBSDKGraphRequest alloc] initWithGraphPath:#"/search?type=place&center=YourLocationLat,YourLocationLong&distance=500" parameters:nil HTTPMethod:#"GET"] startWithCompletionHandler:^(FBSDKGraphRequestConnection *connection, id result, NSError *error) {
NSLog(#"result %#",result);
}];
Hope it helps you..

Swift 3.2 version of #Satish A answer.
func getPlaceId() {
let locManager = CLLocationManager()
locManager.requestWhenInUseAuthorization()
var currentLocation = CLLocation()
if( CLLocationManager.authorizationStatus() == .authorizedWhenInUse ||
CLLocationManager.authorizationStatus() == .authorizedAlways) {
currentLocation = locManager.location!
let param = ["center":"\(currentLocation.coordinate.latitude),\(currentLocation.coordinate.longitude)","type":"place","distance":"100"]
FBSDKGraphRequest(graphPath: "/search", parameters: param).start(completionHandler: { (connection, result, error) -> Void in
if (error == nil) {
guard let data = result as? NSDictionary else {
return
}
guard let arrPlaceIDs = data.value(forKey: "data") as? [NSDictionary] else {
return
}
guard let firstPlace = arrPlaceIDs.first else {
return
}
//First facebook place id.
print(firstPlace.value(forKey: "id") as! String)
} else {
print(error?.localizedDescription ?? "error")
}
})
}
}
For Facebook sharing with attaching placeId
let photo = Photo(image: img, userGenerated: true)
var content = PhotoShareContent()
content.photos = [photo]
content.placeId = id //Facebook placeId
let sharer = GraphSharer(content: content)
sharer.failsOnInvalidData = true
do {
try sharer.share()
} catch {
print("errorrrr")
}
sharer.completion = { FBresult in
switch FBresult {
case .failed(let error):
print(error)
break
case .success(_):
//code
break
default:
break
}
}

You need to set the place (which is actually a Page ID) field within the POST request on /me/photos.
See https://developers.facebook.com/docs/graph-api/reference/v2.0/user/photos/#publish
On iOS, you can use the PlacePicker UI component of the FB iOS SDK for that, as described here: https://developers.facebook.com/docs/ios/ui-controls#placepicker
