崩潰的註銷功能在Facebook在應用程序委託方法sdk3.1

Question

I am using facebook sdk 3.1 & FBloginview.So i want to perform logout functionality 
from other view controller.. 
Here is my code, 

-(void)logout 
{ 
    AppDelegate *appdelegate = [[UIApplication sharedApplication] delegate]; 

    if (FBSession.activeSession.isOpen) 
    { 
     [appdelegate closeSession];  
    } 
    [appdelegate openSessionWithAllowLoginUI:NO]; 
} 

，

- (void) closeSession 
{ 
    [FBSession.activeSession closeAndClearTokenInformation]; 
} 

所以在closeSession方法我得到EXC_BAD_ACCESS。

Answer 1

在註銷按鈕點擊刪除存儲在userdefault所有按鍵爲Facebook

- (void)fbDidLogout 
{ 
    NSHTTPCookie *cookie; 
    NSHTTPCookieStorage *storage = [NSHTTPCookieStorage sharedHTTPCookieStorage]; 

    for (cookie in [storage cookies]) 
    { 
     NSString* domainName = [cookie domain]; 
     NSRange domainRange = [domainName rangeOfString:@"facebook"]; 
     if(domainRange.length > 0) 
     { 
      [storage deleteCookie:cookie]; 
     } 
    } 
} 

OR

Facebook類已經包含在其invalidateSession功能的餅乾取出，

這就是所謂的[facebook logout];
