如何从Facebook iOS sdk获取好友列表
我使用的是iOS sdk v3.18.1,我想获取所有Facebook好友。我可以获取好友数,但数据为零 这是我的密码如何从Facebook iOS sdk获取好友列表,ios,objective-c,iphone,facebook-graph-api,Ios,Objective C,Iphone,Facebook Graph Api,我使用的是iOS sdk v3.18.1,我想获取所有Facebook好友。我可以获取好友数,但数据为零 这是我的密码 [FBRequestConnection startWithGraphPath:@"me/friends" parameters:nil HTTPMethod:@"GET" completionHandler:^(FBRequestConnection *connection, id result, NSError *error) { NSLog(@"resul
[FBRequestConnection startWithGraphPath:@"me/friends" parameters:nil HTTPMethod:@"GET" completionHandler:^(FBRequestConnection *connection, id result, NSError *error) {
NSLog(@"result %@",result);
}];
输出
{
data = (
);
summary = {
"total_count" = 840;
};
}
由于v2.0版您无法再获得完整的好友列表,因此您也只能获得授权您应用程序的好友
在这个帖子中也可以看到我的答案:因为Graph API的V2.0版,你只能获得与你的应用程序连接的朋友列表。在Graph API的v2.0中,调用/me/friends返回使用该应用程序的人的朋友。是的,可以获取计数,但无法访问好友列表 4月份之后发布的所有Facebook SDK都否认了获取全部好友列表的功能 参考: 使用FB SDK 3.0和2.0以上的API版本,您需要调用下面的函数(与我/朋友一起使用图形API),以获取使用相同应用程序的FB朋友列表
// get friends which use the app
-(void) getMineFriends
{
[FBRequestConnection startWithGraphPath:@"me/friends"
parameters:nil
HTTPMethod:@"GET"
completionHandler:^(
FBRequestConnection *connection,
id result,
NSError *error
) {
NSLog(@"me/friends result=%@",result);
NSLog(@"me/friends error = %@", error.description);
NSArray *friendList = [result objectForKey:@"data"];
[m_allFriends addObjectsFromArray: friendList];
}];
}
注:1)上述查询返回的好友数默认限制为25。2) 如果下一个链接出现在结果中,这意味着在下一个查询中,您将获取更多的朋友,以此类推。3) 或者,您可以更改限制(减少限制,从25超出限制),并在参数中传递该限制

对于非应用程序好友-
// m_invitableFriends - global array which will hold the list of invitable friends
另外,要获得非应用程序好友,您需要使用(/me/invitable_friends),如下所示-
- (void) getAllInvitableFriends
{
NSMutableArray *tempFriendsList = [[NSMutableArray alloc] init];
NSDictionary *limitParam = [NSDictionary dictionaryWithObjectsAndKeys:@"100", @"limit", nil];
[self getAllInvitableFriendsFromFB:limitParam addInList:tempFriendsList];
}
- (void) getAllInvitableFriendsFromFB:(NSDictionary*)parameters
addInList:(NSMutableArray *)tempFriendsList
{
[FBRequestConnection startWithGraphPath:@"/me/invitable_friends"
parameters:parameters
HTTPMethod:@"GET"
completionHandler:^(
FBRequestConnection *connection,
id result,
NSError *error
) {
NSLog(@"error=%@",error);
NSLog(@"result=%@",result);
NSArray *friendArray = [result objectForKey:@"data"];
[tempFriendsList addObjectsFromArray:friendArray];
NSDictionary *paging = [result objectForKey:@"paging"];
NSString *next = nil;
next = [paging objectForKey:@"next"];
if(next != nil)
{
NSDictionary *cursor = [paging objectForKey:@"cursors"];
NSString *after = [cursor objectForKey:@"after"];
//NSString *before = [cursor objectForKey:@"before"];
NSDictionary *limitParam = [NSDictionary dictionaryWithObjectsAndKeys:
@"100", @"limit", after, @"after"
, nil
];
[self getAllInvitableFriendsFromFB:limitParam addInList:tempFriendsList];
}
else
{
[self replaceGlobalListWithRecentData:tempFriendsList];
}
}];
}
- (void) replaceGlobalListWithRecentData:(NSMutableArray *)tempFriendsList
{
// replace global from received list
[m_invitableFriends removeAllObjects];
[m_invitableFriends addObjectsFromArray:tempFriendsList];
//NSLog(@"friendsList = %d", [m_invitableFriends count]);
[tempFriendsList release];
}
邀请非应用程序好友-
您将通过me/invitable_friends graph api返回的好友列表获得邀请令牌。您可以在FBWebDialogs中使用这些邀请令牌向朋友发送邀请,如下所示
- (void) openFacebookFeedDialogForFriend:(NSString *)userInviteTokens {
NSMutableDictionary *params = [NSMutableDictionary dictionaryWithObjectsAndKeys:
userInviteTokens, @"to",
nil, @"object_id",
@"send", @"action_type",
actionLinksStr, @"actions",
nil];
[FBWebDialogs
presentRequestsDialogModallyWithSession:nil
message:@"Hi friend, I am playing game. Come and play this awesome game with me."
title:nil
parameters:params
handler:^(
FBWebDialogResult result,
NSURL *url,
NSError *error)
{
if (error) {
// Error launching the dialog or sending the request.
NSLog(@"Error sending request : %@", error.description);
}
else
{
if (result == FBWebDialogResultDialogNotCompleted)
{
// User clicked the "x" icon
NSLog(@"User canceled request.");
NSLog(@"Friend post dialog not complete, error: %@", error.description);
}
else
{
NSDictionary *resultParams = [g_mainApp->m_appDelegate parseURLParams:[url query]];
if (![resultParams valueForKey:@"request"])
{
// User clicked the Cancel button
NSLog(@"User canceled request.");
}
else
{
NSString *requestID = [resultParams valueForKey:@"request"];
// here you will get the fb id of the friend you invited,
// you can use this id to reward the sender when receiver accepts the request
NSLog(@"Feed post ID: %@", requestID);
NSLog(@"Friend post dialog complete: %@", url);
}
}
}
}];
}
检查这个/me/friendlist是否错误,它会为您提供列表,但不会为您提供朋友
- (void) openFacebookFeedDialogForFriend:(NSString *)userInviteTokens {
NSMutableDictionary *params = [NSMutableDictionary dictionaryWithObjectsAndKeys:
userInviteTokens, @"to",
nil, @"object_id",
@"send", @"action_type",
actionLinksStr, @"actions",
nil];
[FBWebDialogs
presentRequestsDialogModallyWithSession:nil
message:@"Hi friend, I am playing game. Come and play this awesome game with me."
title:nil
parameters:params
handler:^(
FBWebDialogResult result,
NSURL *url,
NSError *error)
{
if (error) {
// Error launching the dialog or sending the request.
NSLog(@"Error sending request : %@", error.description);
}
else
{
if (result == FBWebDialogResultDialogNotCompleted)
{
// User clicked the "x" icon
NSLog(@"User canceled request.");
NSLog(@"Friend post dialog not complete, error: %@", error.description);
}
else
{
NSDictionary *resultParams = [g_mainApp->m_appDelegate parseURLParams:[url query]];
if (![resultParams valueForKey:@"request"])
{
// User clicked the Cancel button
NSLog(@"User canceled request.");
}
else
{
NSString *requestID = [resultParams valueForKey:@"request"];
// here you will get the fb id of the friend you invited,
// you can use this id to reward the sender when receiver accepts the request
NSLog(@"Feed post ID: %@", requestID);
NSLog(@"Friend post dialog complete: %@", url);
}
}
}
}];
}
