多个requestWithGraphPath Facebook iOS

Question

也许是一个简单的问题,但我似乎无法得到它.我想获取用户个人资料图片,但也希望搜索他/她的帖子.像这样:

[facebook requestWithGraphPath:@"me/picture?type=large" andDelegate:self];
[facebook requestWithGraphPath:@"me/home?q=TEST" andDelegate:self];

我可以使用以下代码获取picute:

- (void)request:(FBRequest*)request didLoad:(id)result{
    if ([result isKindOfClass:[NSData class]])
    {

        UIImage *image = [[UIImage alloc] initWithData:result];
        UIImageView *profilePicture = [[UIImageView alloc] initWithImage:image];
        [image release];
        profilePicture.frame = CGRectMake(20, 20, 80, 80);
        [self.view addSubview:profilePicture];
        [profilePicture release];

    }
}

但我不知道如何获取搜索查询数据.

任何帮助都会很棒!日Thnx

Answer 1

requestWithGraphPath:andDelegate:返回指向类型对象的指针FBRequest.保存并稍后使用它来区分request:didLoad:将其与传递给此方法的第一个参数进行比较的请求.

例如,您可以拥有两个属性来保存请求对象.虽然,如果您要处理许多请求,您可以使用类似的容器NSDictionary.

self.pictureRequest = [facebook requestWithGraphPath:@"me/picture?type=large" andDelegate:self];
self.homeRequest = [facebook requestWithGraphPath:@"me/home?q=TEST" andDelegate:self];

然后在request:didLoad::

- (void)request:(FBRequest*)request didLoad:(id)result {
    if (request == self.homeRequest) {
        // ...
    } else if (request == self.pictureRequest) {
        // ...
    }
}
