我正试图弄清楚这个错误意味着什么。。。
我正在尝试通过Facebook sdk获取用户信息。我只需要他们的电子邮件和名称
Error Domain=facebookErrDomain Code=10000 "The operation couldn’t be completed. (facebookErrDomain error 10000.)" UserInfo=0xde94ad0 {error=<CFBasicHash 0xde7d100 [0x3f616650]>{type = mutable dict, count = 3,
entries =>
2 : <CFString 0xde722a0 [0x3f616650]>{contents = "type"} = <CFString 0xdeba1a0 [0x3f616650]>{contents = "OAuthException"}
3 : <CFString 0xde6ba20 [0x3f616650]>{contents = "message"} = <CFString 0xdeb12a0 [0x3f616650]>{contents = "An active access token must be used to query information about the current user."}
6 : <CFString 0xde74c40 [0x3f616650]>{contents = "code"} = 2500
}
}
我的基本代码。。。（下面是我的视图DidLoad）
facebook = [[Facebook alloc] initWithAppId:@"random#123456" andDelegate:self];
[self login];
（下面是我的登录方法）
- (void) login {
NSArray *permissionsArray = [NSArray arrayWithObjects:@"email", nil];
[facebook authorize:permissionsArray];
}
（和我的Facebook请求方法…）
- (void)request:(FBRequest *)request didLoad:(id)result {
NSLog(@"Inside didLoad");
if ([result isKindOfClass:[NSArray class]]) {
result = [result objectAtIndex:0];
}
// When we ask for user infor this will happen.
if ([result isKindOfClass:[NSDictionary class]]){
//NSDictionary *hash = result;
NSLog(@"Name: %@", [result objectForKey:@"name"]);
}
if ([result isKindOfClass:[NSData class]])
{
NSLog(@"Profile Picture");
//[profilePicture release];
//profilePicture = [[UIImage alloc] initWithData: result];
}
NSLog(@"request returns %@",result);
//if ([result objectForKey:@"owner"]) {}
};
- (void)request:(FBRequest *)request didFailWithError:(NSError *)error{
NSLog(@"%@",error);
}
我真的很困惑为什么我会出现错误，以及我需要更改或添加什么来修复它…
有什么想法吗？
编辑：我的请求代码：：：
- (IBAction)requestFBFriends:(id)sender {
NSLog(@"HERE");
[facebook requestWithGraphPath:@"me/friends" andDelegate:self];
}
以下是如何获取姓名和电子邮件。。。我没有测试它，所以如果它不起作用，就告诉我，我会发现问题的。
如果您没有有效的访问令牌，则发送请求的方法需要进行身份验证

如果您有问题，请在评论中询问他们
如果您在模拟器/设备上运行应用程序，请尝试清理构建并重新安装应用程序。当前错误可能是由于非活动/已吊销的访问令牌对访问用户数据不再有效。希望它能有所帮助！！！
