NSMutableDictionary *params = [NSMutableDictionary dictionaryWithObjectsAndKeys:
@"Sharing Tutorial", @"name",
@"Build great social apps and get more installs.", @"caption",
@"Allow your users to share stories on Facebook from your app using the iOS SDK.", @"description",
@"https://developers.facebook.com/docs/ios/share/", @"link",

@"100006771363037",@"to",
nil];
// Show the feed dialog
[FBWebDialogs presentFeedDialogModallyWithSession:nil
parameters:params
handler:^(FBWebDialogResult result, NSURL *resultURL, NSError *error) {
if (error) {
// An error occurred, we need to handle the error
// See: https://developers.facebook.com/docs/ios/errors
NSLog(@"Error publishing story: %@", error.description);
} else {
if (result == FBWebDialogResultDialogNotCompleted) {
// User canceled.
NSLog(@"User cancelled.");
} else {
// Handle the publish feed callback
NSDictionary *urlParams = [self parseURLParams:[resultURL query]];
if (![urlParams valueForKey:@"post_id"]) {
// User canceled.
NSLog(@"User cancelled.");
} else {
// User clicked the Share button
NSLog(@"fb web dialog result=====>%@",result);
NSString *result = [NSString stringWithFormat: @"Posted story, id: %@", [urlParams valueForKey:@"post_id"]];
NSLog(@"result %@", result);
}
}
}
}];
While adding friends profile_id's separated by comma in @"to" field getting error.Added screen shot in below 在@“至”字段中添加朋友profile_id时,用逗号分隔时出现错误。在下面添加了屏幕截图
You cannot add multiple ids in the to
parameter in a Feed Dialog . 您不能在Feed对话框的
to
参数中添加多个ID。 In fact there's no way to post a feed to multiple friends at once. 实际上,无法一次将提要发布给多个朋友。 You have to invoke the dialog for each of the friend separately.
您必须分别为每个朋友调用对话框。
According to documentation , to
is: 根据文档 ,
to
是:
The ID or username of the profile that this story will be published to.
此故事将发布到的配置文件的ID或用户名。 If this is unspecified, it defaults to the value of from.
如果未指定,则默认为from的值。
