我在recorer的线程有问题，我有一个联系人列表600和6显示我以下错误。ABAddressBookRef多线程错误
线程1：EXC_BAD_ACCESS（码= 1，地址= 0x29）
是下面的代码
-(void) actualizarContactos

不要在这里使用信号量。相反，了解异步处理程序的工作方式。他们希望是异步的，你应该让它们是异步的。 – matt 2014-09-30 16:46:18
@matt我可以做你说你给我的例子？ – user1555264 2014-09-30 18:56:11
究竟是什么的例子？你所说的只是“我有线程问题。”所以停止使用线程。您不知道在完成处理程序之前是否授予访问权限，所以_that_是进行下一步骤的地方。这就是完成处理程序是_for_;这意味着，这个过程是_completed_。 – matt 2014-09-30 18:58:00
