我有一個自定義鍵盤，圖像分爲類別。 Rigth現在我在每個類別中都有12張圖像。如果我有20個圖像的類別，例如鍵盤崩潰。我一直在尋找一個解決方案很長一段時間沒有運氣。 當我調試在我的iPhone的鍵盤，我收到了SIGQUIT信號：自定義鍵盤崩潰共享庫事件（內存泄漏？）

有什麼想法？ UPDATE 我創建了一個期望斷點，我得到了加載nib文件的斷點。

self.inputView = (UIInputView *)self.keyboard;

更新2： 我敢肯定它是與內存問題...如果我在單元格中顯示只是一個彩色背景它的工作原理好。現在，如果我顯示imgages，如果它們小於10-15有沒有問題，但如果我有更多的將與不同的錯誤崩潰，像那些高於或：
libz.1.dylib`inflate:
libsystem_kernel.dylib`_kernelrpc_mach_vm_deallocate_trap:
起初，我有一個滾動視圖和我認爲問題在於它直接加載了所有圖像，所以我嘗試使用collectionView，但結果相同。我試圖用相同的結果加載圖像3種不同的方式：
UIImage imageWithContentsOfFile:
UIImage imageWithData:
UIImage imageNamed:
嘗試創建[異常斷點]（https://stackoverflow.com/questions/17802662/exception-breakpoint-in-xcode）並重現崩潰;你可能會得到你的代碼崩潰的地方。 – the4kman
@ the4kman嘗試並獲得它加載nib文件的位置。我將用代碼 – emiliomarin
更新問題你能告訴我們什麼是實際例外嗎？ –
