iphone开发人员使用fbconnect api获取用户配置文件名、电子邮件

我用这个从我的iphone应用程序在facebook上贴墙

kAppId =@"zsdgdfgjhjk";
    if (!kAppId) {
        NSLog(@"missing app id!");
        exit(1);
        return nil;
    }

    if ((self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil])) {
        _permissions =  [[NSArray arrayWithObjects:
                          // @"read_stream", @"publish_stream", @"offline_access",@"user_events",@"friends_events",@"rsvp_event",nil] retain];
                          @"read_stream",@"email", @"publish_stream", @"offline_access",@"user_events",@"friends_events",@"rsvp_event",@"create_event",nil] retain];
        _facebook = [[Facebook alloc] initWithAppId:kAppId
                                        andDelegate:self];



- (IBAction)publishStream:(id)sender {

    SBJSON *jsonWriter = [[SBJSON new] autorelease];

    NSDictionary* actionLinks = [NSArray arrayWithObjects:[NSDictionary dictionaryWithObjectsAndKeys:
                                                           @"Always Running",@"text",@"http://itsti.me/",@"href", nil], nil];

    NSString *actionLinksStr = [jsonWriter stringWithObject:actionLinks];
    NSDictionary* attachment = [NSDictionary dictionaryWithObjectsAndKeys:
                                @"a long run", @"name",
                                @"The Facebook Running app", @"caption",
                                @"it is fun", @"description",
                                @"http://itsti.me/", @"href", nil];
    NSString *attachmentStr = [jsonWriter stringWithObject:attachment];
    NSMutableDictionary* params = [NSMutableDictionary dictionaryWithObjectsAndKeys:
                                   @"Share on Facebook",  @"user_message_prompt",
                                   actionLinksStr, @"action_links",
                                   attachmentStr, @"attachment",
                                   nil];

    [_facebook dialog:@"publish.stream"
            andParams:params
          andDelegate:self];
}

墙张贴是好的，但现在我想得到用户的facebook个人资料名称加上电子邮件，我正在尝试用户登录后的代码

[_facebook requestWithGraphPath:@"me?fields=id,name,email" andDelegate:self];

及

但即使此fbrequest委托方法

-（void）request:（fbrequest*）request didLoad:（id）result

，它也不起作用，请不要调用它。导游，我已经在这里呆了很长时间了。提前谢谢。你好，萨阿德。

试着这样做：

[_facebook requestWithGraphPath:@"me" andDelegate:self];

- (void)request:(FBRequest *)request didLoad:(id)result {
    if ([result isKindOfClass:[NSArray class]]){
        result = [result objectAtIndex:0];
    }
    if ([result objectForKey:@"owner"]) {
    }else{
                NSLog(@"response is %@", result);       
        NSString *email =[result objectForKey:@"email"];
        NSString *userFbId =[result objectForKey:@"id"];
                // grab other fields
    }
}

您将通过以下方式解析响应：

[_facebook requestWithGraphPath:@"me" andDelegate:self];

- (void)request:(FBRequest *)request didLoad:(id)result {
    if ([result isKindOfClass:[NSArray class]]){
        result = [result objectAtIndex:0];
    }
    if ([result objectForKey:@"owner"]) {
    }else{
                NSLog(@"response is %@", result);       
        NSString *email =[result objectForKey:@"email"];
        NSString *userFbId =[result objectForKey:@"id"];
                // grab other fields
    }
}

试着这样做：

[_facebook requestWithGraphPath:@"me" andDelegate:self];

- (void)request:(FBRequest *)request didLoad:(id)result {
    if ([result isKindOfClass:[NSArray class]]){
        result = [result objectAtIndex:0];
    }
    if ([result objectForKey:@"owner"]) {
    }else{
                NSLog(@"response is %@", result);       
        NSString *email =[result objectForKey:@"email"];
        NSString *userFbId =[result objectForKey:@"id"];
                // grab other fields
    }
}

- (void)request:(FBRequest *)request didLoad:(id)result {
    if ([result isKindOfClass:[NSArray class]]){
        result = [result objectAtIndex:0];
    }
    if ([result objectForKey:@"owner"]) {
    }else{
                NSLog(@"response is %@", result);       
        NSString *email =[result objectForKey:@"email"];
        NSString *userFbId =[result objectForKey:@"id"];
                // grab other fields
    }
}
