问题描述

我正在iOS 5中使用xmppframework开发聊天应用程序；效果很好.

I am developing a chat application using xmppframework in iOS 5; it works perfectly.

但是我将Xcode更新为4.5.1，将iOS 5更新为iOS 6，将Mac OS更新为10.7.5，由于弃用问题，该项目无法正常工作.我将iOS 6中的所有方法替换为新方法，除了以下一种方法:

But I updated my Xcode to 4.5.1, iOS 5 to iOS 6 and my Mac OS to 10.7.5, and the project did not work due to deprecation issues. I replaced all methods with new methods in iOS 6 except this one:

dispatch_get_current_queue()  

如何在iOS 6中替换此方法?

How can I replace this method in iOS 6?

推荐答案

这取决于您需要通过此调用实现的内容.
苹果公司指出，无论如何都应将其用于调试.

It depends what you need to achieve with this call.
Apple states that it should be used for debugging anyway.

也许队列无关紧要(因为您只需要一个后台队列)，所以获取具有特定优先级(dispatch_get_global_queue(dispatch_queue_priority_t priority, unsigned long flags);)的全局队列

Perhaps the queue does not matter (as you just need a background queue) so get a global queue with specific priority (dispatch_get_global_queue(dispatch_queue_priority_t priority, unsigned long flags);)

OR，

如果您确实需要在同一队列中执行一些代码，请创建一个队列，将其保留并在其中分派所有任务.

If you do need to execute some pieces of code in the same queue , create a queue, retain it and dispatch all your tasks there.
