Facebook iOS SDK - 向Facebook用户发送应用请求

Question

我试图通过Facebook使用facebook iOS SDK发送应用程序请求,我使用以下代码:

NSString *message = [[NSString alloc] initWithFormat:@"blah blah blah"];
NSString *data = [[NSString alloc] initWithFormat:@"blah blah blah"];

NSMutableDictionary *params = [NSMutableDictionary dictionaryWithObjectsAndKeys:message, @"message", data, @"data", nil];
[_facebook requestWithGraphPath:[NSString stringWithFormat:@"%@/apprequests",userID] andParams:params andHttpMethod:@"POST" andDelegate:self];

[message release];
[data release];

这给了我以下错误:

Error: Error Domain=facebookErrDomain Code=10000 "The operation couldn’t be completed. (facebookErrDomain error 10000.)" UserInfo=0x788c5b0 {error=<CFBasicHash 0x788c080 [0x1bf53e0]>{type = mutable dict, count = 2,
entries =>
    2 : <CFString 0x788b560 [0x1bf53e0]>{contents = "type"} = <CFString 0x788c3f0 [0x1bf53e0]>{contents = "OAuthException"}
    3 : <CFString 0x788c560 [0x1bf53e0]>{contents = "message"} = <CFString 0x788c480 [0x1bf53e0]>{contents = "(#200) Invalid Request: There was a problem with the parameters of the request. Body of an error/warning message. Title is: Invalid Request"}
}

那么有没有人成功用这个,或者你知道一种使用facebook iOS SDK向facebook用户发送请求的方法吗？

谢谢

您可以使用Facebook SDK轻松发送应用程序请求

如需制作应用程序请求请确保执行以下步骤

1)确保在应用程序文件夹中添加了最新的Facebook SDK

如果没有,你可以从下载该链接.

现在,您只需在项目文件夹中添加FBConnect文件夹即可.

2)然后确保您已将您的iphone应用程序注册为"Facebook上的应用程序"类型在"基本应用程序设置"下选择您的应用程序如何与Facebook集成.

如果没有,你可以在这里做.

NSString *friendId=@"FacebookId Of Your Friends";

NSLog(@"%@",friendId);

NSMutableDictionary* params = [NSMutableDictionary dictionaryWithObjectsAndKeys:@"Hi please add me as a friend.",  @"message",
                                   friendId, @"to",
                                   nil];
 [appDelegate.facebook dialog:@"apprequests" andParams:params  andDelegate:self];

请不要忘记在ViewController类中首先采用FBdialogDelegate协议.
