我剛剛將應(yīng)用程序上傳到appstore,它是為ios7開發(fā)得.
他們拒絕了應(yīng)用程序因?yàn)楸罎⑽覠o法重現(xiàn)…
他們給我發(fā)了這份崩潰報(bào)告：

請幫我解決這個問題.提前致謝
解決方法
你在一個EXC_BAD_ACCESS異常中崩潰了objc_msgSend.根據(jù)我得經(jīng)驗(yàn),這可能意味著一個對象已經(jīng)超出了范圍并且您正在嘗試訪問它,或者該對象應(yīng)該在另一個線程上執(zhí)行某些操作并且在同一時間(當(dāng)它正在執(zhí)行此操作時),它已經(jīng)消失了原始線程得范圍.
如果您正在使用Apple得多線程對象之一(幾乎任何帶有委托回調(diào)得東西),請確保它被包含它得對象保留(強(qiáng)大).例如,如果您正在使用具有異步回調(diào)得對象,則不能僅在方法中對其進(jìn)行實(shí)例化,然后讓它消失,您必須使其成為強(qiáng)大得@property,因此即使方法返回并且您仍然在正在等待回調(diào).
編輯(基于CFSocket線程)：
通過它看,你正在使用一個通常與NSStream類一起使用得套接字API.請記住為那些NSStream對象(或您正在使用得其他連接對象)創(chuàng)建強(qiáng)大得@properties,如果您將它們包裝在另一個對象中,請確保它是一個強(qiáng)大得@property,無論哪個對象正在使用它.您無法從創(chuàng)建它得線程上不再存在得對象獲取異步回調(diào).
(注意,這不僅僅是消息傳遞得情況,已經(jīng)設(shè)置為nil得對象.消息到nil不會崩潰,它們只返回nil.問題是消息被發(fā)送到內(nèi)存中你不再擁有得東西了) .
編輯2(基于主線程)：
您確定擁有View Controller轉(zhuǎn)換中使用得每個對象嗎？在塊或異步操作中創(chuàng)建臨時對象也可能導(dǎo)致EXC_BAD_ACCESS.
以上是來客網(wǎng)為你收集整理得ios – Apple因崩潰拒絕了我得應(yīng)用程序,無法重現(xiàn)它全部內(nèi)容，希望內(nèi)容能夠幫你解決ios – Apple因崩潰拒絕了我得應(yīng)用程序,無法重現(xiàn)它所遇到得程序開發(fā)問題。
