How to comment or like a photo in facebook through FBconnect or Graph API in iPhone SDK?
I am developing a iPhone application in which I want to Comment or Like a Photo on Facebook.
For Facebo开发者_JS百科ok integration I am using FBConnect and Graph API.
I am getting friends Photos on my wall in my application, now I want to Like or Comment on them through my iPhone Application.
Please suggest me how can i obtain that.
Thanks in Advance.
To "Like" a Photo (or everthing else with an ID) just post your Acces-Token to the Graph API, e.g. your photo has the ID 123456789. So you have to post your Access-Token to https://graph.facebook.com/123456789/likes.
To comment on a Photo do the same, but post a message (as a parameter) to the Graph API, e.g. https://graph.facebook.com/123456789/comments.
In Code call the following method (defined in Facebook.h) with your path and no parameters for "Like" and a message as a parameter for "Comment":
-(void) requestWithGraphPath:(NSString *)graphPath
andParams:(NSMutableDictionary *)params
andHttpMethod:(NSString *)httpMethod
andDelegate:(id <FBRequestDelegate>)delegate
Note, that the httpMethod should be "POST" and the Facebook iOS SDK automaticaly adds your Access-Token.
For more information read the "Publishing" part on: http://developers.facebook.com/docs/reference/api
Edit: Like deanWombourne wrote in the comments: Just post an NSMutableDictionary like this
[NSMutableDictionary dictionaryWithObjectsAndKeys:@"This is my comment", @"message", nil];
for the comments or an empty NSMutableDictionary like:
[NSMutableDictionary dictionary]
if you want to like a post.
The response from the Facebook servers should be result = true.
