GKSession alloc/release/alloc =泄漏和崩潰

我有一個應用程序拋出GKSession並在各種條件下（連接超時，會話失敗等）產生新的應用程序。不過，我得到了內存泄漏，並且在重新連接幾次循環之後，它有時會崩潰。GKSession alloc/release/alloc =泄漏和崩潰

這裏是我的代碼：

- (void) netConnect:(id) sender { 
    NSLog(@"allocating GKSession"); 

    currentSession = [[GKSession alloc] initWithSessionID:nil displayName:nil sessionMode:GKSessionModePeer]; 
    currentSession.delegate = self; 
    currentSession.available = YES; 
    currentSession.disconnectTimeout = 0; 
    [currentSession setDataReceiveHandler: self withContext:nil]; 
     } 

- (void) netDisconnect:(id) sender { 
    NSLog(@"DISCONNECTING BY REQUEST"); 

    [currentSession disconnectFromAllPeers]; 
    [currentSession setAvailable:NO]; 
    [currentSession setDelegate:nil]; 
    [currentSession setDataReceiveHandler:nil withContext:nil]; 
    [currentSession release]; 
    currentSession = nil; 
    }

有這麼等待成功連接的定時器;如果它沒有得到，則調用netDisconnect，然後在5秒的NSTimer延遲後再次調用netConnect。

我越來越泄露GKList，GKTable和GKAutoPeerIDTable對象，像這樣的崩潰（在ALLOC後總是發生）：

這裏的另一個問題：

問題：
•這是釋放和重新分配GKSession的正確方法嗎？
•我是不是應該先拆除並重新分配連接之間的GKSession？

我傾向於GameKit的越野車，但不釋放會話是更好的方式去反正當意圖是不斷嘗試連接或重新連接。 – 2010-09-06 06:37:57

我沒有你的答案，但我已經擺弄GKSession兩天了，是的，它似乎經常崩潰，經常在dealloc上...看起來真的很糟糕... – Jonny 2010-10-04 10:07:40

這是一個已知問題。解決方法是不傳遞nil作爲sessionID： [[GKSession alloc] initWithSessionID：@「com.put.something.here」displayName：nil sessionMode：GKSessionModePeer];

偉大的提示，謝謝你。 – 2010-11-30 22:44:03
