[英]Facebook FQL multiquery in iOS SDK
我正在寻找有关如何通过iOS SDK向Facebook发送多查询fql请求的一些文档或示例代码。 我找到了一些较旧的样品,但它们对我不起作用。 我用查询填充了一个NSDictionary
,我尝试通过[[FBRequest requestWithDelegate:self] call:@"facebook.fql.multiquery" params:params];
发送请求[[FBRequest requestWithDelegate:self] call:@"facebook.fql.multiquery" params:params];
,正如我读过的样本中所述,但是我得到了一个“无法识别的选择器发送到类”错误,我无法在FBRequest.h中找到“requestWithDelegate”方法。 它被弃用了吗? 对此的一些帮助将非常感谢!
// Construct your FQL Query
NSString* fql = [NSString stringWithFormat:@"SELECT uid, name, hometown_location from user where uid IN (SELECT uid2 FROM friend WHERE uid1=%lld) and hometown_location != '' ORDER BY rand() limit 4", facebookId];
// Create a params dictionary
NSMutableDictionary* params = [NSMutableDictionary dictionaryWithObject:fql forKey:@"query"];
// Make the request
[facebook requestWithMethodName:@"fql.query" andParams:params andHttpMethod:@"GET" andDelegate:self];
将使用响应调用委托FBRequestDelegate。 根据您的需要,您可以执行以下操作:
- (void)request:(FBRequest*)request didLoad:(id)result {
NSLog(@"didLoad() received result: %@", result);
}
facebook对象创建如下:
Facebook * facebook = [[Facebook alloc] initWithAppId:kAppID];
有关如何设置的更多信息,请访问: https : //developers.facebook.com/docs/guides/mobile/
根据您的FQL查询,您将需要用户的权限。 请在此处查看权限列表: https : //developers.facebook.com/docs/authentication/permissions/
这里还有一个用于FQL查询的测试控制台: https : //developers.facebook.com/docs/reference/rest/fql.query/
如果你想做一个Multiquery而不是一个查询,它看起来像:
NSString* fql1 = [NSString stringWithFormat:
@"select uid2 from friend where uid1 == %lld order by rand() limit 10", facebookId];
NSString* fql2 = [NSString stringWithFormat:
@"select uid, name from user where uid in (select uid2 from #queryID)"];
NSString* fql3 = [NSString stringWithFormat:
@"select uid, status_id, message from status where uid in (select uid from #queryName) limit 1"];
NSString* fql = [NSString stringWithFormat:
@"{\"queryID\":\"%@\",\"queryName\":\"%@\",\"queryStatus\":\"%@\"}",fql1,fql2,fql3];
NSDictionary* params = [NSDictionary dictionaryWithObject:fql forKey:@"queries"];
[facebook call:@"fql.multiquery" params:params];
