ios memory leak when accessing phone book这是我的orignal问题，这是崩溃日志。内存泄漏问题已经解决，但是当我访问联系人时弹出应用程序崩溃并再次弹出导航控制器推送和访问联系人，重复此过程3-4次，应用程序将崩溃。
崩溃日志：

提前感谢：）
答案 0 :(得分：1)
您使用了错误的数组计数值。尝试：
CFArrayRef allPeople = ABAddressBookCopyArrayOfAllPeopleInSourceWithSortOrdering(addressBook, source, kABPersonSortByFirstName);
CFIndex nPeople = CFArrayGetCount(allPeople);
顺便说一下，我之前看过这段代码时遇到同样的错误。你从哪里得到的？
