我正在尝试使用新的(测试版)ios sdk 3.0在一个应用程序中添加Facebook集成.所有我想要发布的状态更新到Facebook.我用FBLoginView登录到Facebook.我把我的应用程序id放在plist的指示在Facebook上.我把一些代码发贴到Facebook.
(void)viewDidLoad
{
[super viewDidLoad];
NSArray *perms;
perms = [NSArray arrayWithObjects:@"status_update",nil];
FBLoginView *loginview =
[[FBLoginView alloc] initWithPermissions:perms];
loginview.frame = CGRectOffset(loginview.frame,5,5);
loginview.delegate = self;
[self.view addSubview:loginview];
// Do any additional setup after loading the view,typically from a nib.
}
- (IBAction)poststatus:(UIButton *)sender {
NSString *message = [NSString stringWithFormat:@"Test staus update"];
[FBRequestConnection startForPostStatusUpdate:message
completionHandler:^(FBRequestConnection *connection,id result,NSError *error) {
[self showAlert:message result:result error:error];
}];
}
- (void)showAlert:(NSString *)message
result:(id)result
error:(NSError *)error {
NSString *alertMsg;
NSString *alertTitle;
if (error) {
alertMsg = error.localizedDescription;
alertTitle = @"Error";
} else {
NSDictionary *resultDict = (NSDictionary *)result;
alertMsg = [NSString stringWithFormat:@"Successfully posted '%@'.\nPost ID: %@",message,[resultDict valueForKey:@"id"]];
alertTitle = @"Success";
}
UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:alertTitle
message:alertMsg
delegate:nil
cancelButtonTitle:@"OK"
otherButtonTitles:nil];
[alertView show];
}
奇怪的是,这段代码可以一直工作.第一次验证用户后,我可以成功发送一个状态更新.之后,所有后续尝试将失败,并显示FBiOSSDK错误5(在控制台中,错误：HTTP状态代码为400).解决此问题的唯一方法是从Facebook帐户中删除该应用程序并重新验证.我不知道问题是什么.我在网上查找解决方案,但找不到任何东西.如果有人知道如何解决这个问题,请让我知道.谢谢
