使用Facebook iOS SDK检索生日 [英] Using Facebook iOS SDK to retrieve birthdays

问题描述

我是新来使用API​​，所以我不知道如何正确执行这个。

我试图获取用户的所有生日朋友。到目前为止，我成功地获得了他们的friendList，然后在理论上我可以简单地ping每个ID并从中获取生日。

然而，我不确定如何实现方法。

当我的viewController加载时： [facebook requestWithGraphPath：@me / friendsandDelegate：self];

发送请求，我实现FBRequestDelegate方法来接收它：

   - （void）request：（FBRequest *）request didLoad：（id）result {
 NSLog（@result is：％@，result）; 
} 
  

到目前为止，我得到一个拥有所有朋友姓名和ID的对象。然而，现在我想循环遍历每个ID，并发送另外几百个请求。我已经知道如何设置循环和请求调用，但是我已经在这个viewController中使用了didLoad方法，我显然需要在返回数据对象后以不同的方式处理数据。

与$（FBRequest *）有关的事情？这是什么，也许我可以去像（请求==的东西）？感谢

解决方案

您可以通过单个fql请求检索您（或用户的）facebook朋友的生日。

您可以在这里阅读有关fql的信息： http：// developers.facebook.com/docs/reference/fql/

但是这里有一些代码供参考（这段代码在一个定义为FBSessionDelegate的类中，和FBRequestDelegate）

   - （void）请求：（FBRequest *）请求didLoad：（id）result {
 / /结果是你的朋友和他们的生日的NSDictionary！ 
} 
 
  - （void）fbDidLogin {
 //一些最佳做法锅炉板代码，用于存储重要的东西从fb 
 NSUserDefaults * defaults = [NSUserDefaults standardUserDefaults]; 
 [defaults setObject：[facebook accessToken] forKey：@FBAccessTokenKey]; 
 [defaults setObject：[facebook expirationDate] forKey：@FBExpirationDateKey]; 
 [默认同步]; 
 
 //现在加载所有我朋友的生日
 NSMutableDictionary * params = 
 [NSMutableDictionary dictionaryWithObjectsAndKeys：
 @select birthday，name，uid，pic_square from user where uid in（select uid2 from friend where uid1 = me（））order by name，
 @query，
 nil]; 
 
 [self.facebook requestWithMethodName：@fql.queryandParams：params andHttpMethod：@POSTandDelegate：self]; 
} 
 
  - （void）loginWithFacebook {
 self.facebook = [[[分配] initWithAppId：@<你的应用程序ID在这里>自动释放]; 
 //重要 - 您需要向朋友的生日请求许可
 [Facebook授权：[NSArray arrayWithObject：@friends_birthday]]; 
} 
  

I'm new to using API's, so I'm not sure how to properly execute this.

I'm trying to get all the birthdays of a user's friends. So far I am successful in getting their friendList, and then in theory I can simply ping each ID and get the birthday from it.

However I'm unsure how on to implement the methods.

When my viewController loads: [facebook requestWithGraphPath:@"me/friends" andDelegate:self];

This sends off the request and I implement the FBRequestDelegate method to receive it:

-(void)request:(FBRequest *)request didLoad:(id)result{
    NSLog(@"result is : %@", result);
}

Works perfectly so far, I get an object with all the friend names and IDs. However, now I'd like to loop through each ID, and send off another few hundred requests. I already know how to setup the loop and the request call, but I've already used the didLoad method in this viewController, and I obviously need to handle the data differently once the data object gets returned.

Something to do with a (FBRequest *)? What is that, maybe I can go something like if(request == something)? Thanks

解决方案

You can retrieve the birthdays of your (or the user's) facebook friends with a single fql request.

You can read about fql here: http://developers.facebook.com/docs/reference/fql/

But here's some code for reference (this code is in a class defined to be a FBSessionDelegate, and FBRequestDelegate)

- (void)request:(FBRequest *)request didLoad:(id)result {
    // result is a NSDictionary of your friends and their birthdays!
}

- (void)fbDidLogin {
    //some best practice boiler plate code for storing important stuff from fb
    NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
    [defaults setObject:[facebook accessToken] forKey:@"FBAccessTokenKey"];
    [defaults setObject:[facebook expirationDate] forKey:@"FBExpirationDateKey"];
    [defaults synchronize];

    //now load all my friend's birthdays
    NSMutableDictionary * params = 
                         [NSMutableDictionary dictionaryWithObjectsAndKeys:
                         @"select birthday, name, uid, pic_square from user where uid in (select uid2 from friend where uid1=me()) order by name", 
                         @"query",
                         nil];

    [self.facebook requestWithMethodName: @"fql.query" andParams: params andHttpMethod: @"POST" andDelegate: self];
}

- (void) loginWithFacebook {
    self.facebook = [[[Facebook alloc] initWithAppId:@"<your app id here>" andDelegate:self] autorelease];
    //IMPORTANT - you need to ask for permission for friend's birthdays
    [facebook authorize:[NSArray arrayWithObject:@"friends_birthday"]];
}
