我剛剛發現這個問題，同時測試我的應用程序，它真的開始煩我。所以環境是什麼樣子如下：安裝Facebook的登錄 - 如果用戶帳戶存在（和應用程序未安裝）登錄失敗
- 沒有Facebook應用
- 用戶登錄到iOS系統帳戶（在設置 - > Facebook的）
當我的應用程序試圖驗證用戶第一次提供了這堵牆的文字：（我試圖清除它一點點）

我知道那稍顯混亂，但我採取的是其犯錯了因爲它認爲用戶取消了登錄過程。事情是，我從來沒有看到小彈出問我，如果我想登錄或接受權限....所以我添加了Facebook應用程序的電話，它的工作...以及這很好，但如果我有一個用戶不是應用程序，但他們有FB登錄在手機上....任何人有任何想法？
我的驗證碼如下：（差不多就只有一點點從FB網站修改）
- (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NSLog(@"Session is no longer valid");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];
}
我試圖改變我進行身份驗證，但總是遇到同樣問題的辦法...任何想法？

您是否在您的權限數組中指定了'basic_info'權限？ – MAB
你打賭！它的工作原理（驗證），如果FB應用程序存在，所以我相信權限是正確的 – Andy
如果您的應用程序權限爲OFF，您可以檢查Facebook下的設置 – MAB
