访问电话簿ios时崩溃的应用程序
ios内存泄漏时访问电话簿是我的原始问题，这是崩溃日志。 内存泄漏问题已得到解决，但当我访问联系人并popup到导航控制器再次推入和访问联系人时，应用程序崩溃，重复此过程3-4次，应用程序将崩溃。
崩溃日志：

提前致谢 ：）
您正在使用错误的数组计数值。 尝试：
CFArrayRef allPeople = ABAddressBookCopyArrayOfAllPeopleInSourceWithSortOrdering(addressBook, source, kABPersonSortByFirstName); CFIndex nPeople = CFArrayGetCount(allPeople);
顺便说一句，我以前看过这个代码，同样的错误。 你在哪里得到它？
