我刚刚发现这个问题，同时测试我的应用程序，它真的开始烦我。所以环境是什么样子如下：安装Facebook的登录 - 如果用户帐户存在（和应用程序未安装）登录失败
- 没有Facebook应用
- 用户登录到iOS系统帐户（在设置 - > Facebook的）
当我的应用程序试图验证用户第一次提供了这堵墙的文字：（我试图清除它一点点）

我知道那稍显混乱，但我采取的是其犯错了因为它认为用户取消了登录过程。事情是，我从来没有看到小弹出问我，如果我想登录或接受权限....所以我添加了Facebook应用程序的电话，它的工作...以及这很好，但如果我有一个用户不是应用程序，但他们有FB登录在手机上....任何人有任何想法？
我的验证码如下：（差不多就只有一点点从FB网站修改）
- (void) facebookSessionChange {
// If the session state is any of the two "open" states when the button is clicked
if (FBSession.activeSession.state == FBSessionStateOpen
|| FBSession.activeSession.state == FBSessionStateOpenTokenExtended) {
// Close the session and remove the access token from the cache
// The session state handler (in the app delegate) will be called automatically
[FBSession.activeSession closeAndClearTokenInformation];
// If the session state is not any of the two "open" states when the button is clicked
} else {
// Open a session showing the user the login UI
[FBSession openActiveSessionWithReadPermissions:permissions
allowLoginUI:YES
completionHandler:
^(FBSession *session, FBSessionState state, NSError *error) {
[self sessionStateChanged:session state:state error:error];
}];
}
}
- (void)sessionStateChanged:(FBSession *)session state:(FBSessionState) state error:(NSError *)error
{
NSLog(@"Session is %@", session);
// If the session was opened successfully
if (!error && state == FBSessionStateOpen){
NSLog(@"Session opened");
// Show the user the logged-in UI
[self userLoggedIn];
return;
}
if (state == FBSessionStateClosed || state == FBSessionStateClosedLoginFailed){
// If the session is closed
NSLog(@"Session closed");
// Show the user the logged-out UI
[self userLoggedOut];
}
// Handle errors
if (error){
NSLog(@"Error occured %@", error);
if ([FBErrorUtility shouldNotifyUserForError:error] == YES){
NSLog(@"Error occured %@", error);
} else {
// If the user cancelled login, do nothing
if ([FBErrorUtility errorCategoryForError:error] == FBErrorCategoryUserCancelled) {
NSLog(@"User cancelled login");
// Handle session closures that happen outside of the app
} else if ([FBErrorUtility errorCategoryForError:error] == FBErrorCategoryAuthenticationReopenSession){
NSLog(@"Session is no longer valid");
} else {
//Get more error information from the error
NSDictionary *errorInformation = [[[error.userInfo objectForKey:@"com.facebook.sdk:ParsedJSONResponseKey"] objectForKey:@"body"] objectForKey:@"error"];
NSLog(@"Error occured : %@", [errorInformation objectForKey:@"message"]);
}
}
// Clear this token
[FBSession.activeSession closeAndClearTokenInformation];
// Show the user the logged-out UI
[self userLoggedOut];
}
}
// Show the user the logged-out UI
- (void)userLoggedOut
{
NSLog(@"User logged out");
}
// Show the user the logged-in UI
- (void)userLoggedIn
{
NSLog(@"User Logged in");
[_delegate doneLogginginToFb];
}
我试图改变我进行身份验证，但总是遇到同样问题的办法...任何想法？

您是否在您的权限数组中指定了'basic_info'权限？ – MAB
你打赌！它的工作原理（验证），如果FB应用程序存在，所以我相信权限是正确的 – Andy
如果您的应用程序权限为OFF，您可以检查Facebook下的设置 – MAB
