-[CFString保留]：消息發送到已釋放實例0x215076c0

Question

我知道這個主題已經被討論過幾次了，但是我無法弄清楚是什么導致了此錯誤消息。 我已經在這里停留了兩個星期，這讓我發瘋。 方法的第一部分為2-4個玩家設置了比賽。 找到比賽后，它將嘗試在特定限制內添加3和4個玩家。 目前，該限制僅設置為3秒，但是我認為一旦准備發布，該限制將會更大。

我知道這是matchmakerViewController代碼中某處的內存錯誤。 當我注釋掉更改場景的代碼時，仍然出現錯誤。 您能告訴我我做錯了什么以及如何解決嗎？

Answer 1

答案最終是我需要釋放

        matchRequest.minPlayers = 3;
        matchRequest.maxPlayers = 4;

重新定義它們的值之前。
