访问 [PFUser currentUser] 导致死锁 [英] Access to [PFUser currentUser] causing deadlock

问题描述

在使用parse iOS sdk v1.2.20 时，多个线程尝试访问[PFUser currentUser] 时偶尔会出现死锁

Getting a deadlock occasionally when several threads trying to access [PFUser currentUser] when using parse iOS sdk v1.2.20

看起来每当我进行 PFQuery 调用或 PFCloud 函数调用时，这些操作也会访问 [PFUser currentUser]，因此如果您从单独的线程进行查询，则会增加死锁的机会.

It looks like whenever I make a PFQuery call or PFCloud function call, these operations also access [PFUser currentUser], so there's increase chance of deadlock if you are making queries from separate threads.

其他人为此找到了解决方案，我怀疑 parse 甚至知道这个问题，因为他们很久以前就关闭了这些相关问题:https://www.parse.com/questions/parse-locking-启动主线程可能出现死锁还有这个:https://www.parse.com/questions/occasional-freezing-at-pfuser-currentuser

Anyone else find a solution for this, I doubt parse even is aware of the problem as they closed these related issues long ago: https://www.parse.com/questions/parse-locking-up-the-main-thread-possible-deadlock And this one: https://www.parse.com/questions/occasional-freezing-at-pfuser-currentuser
