What is the equivalent of C # 'Thread.Join ()' in Cocoa?

Question

I am making an iPhone application using threads. For some time I used C #, there was a method Thread.Join()that blocks the current thread to perform specific thread terminations. What is equivalent in Cocoa for this? Or alternatives?

PS. I am using NSThread.

I find a method like "waitForThreadExit" that blocks the thread of the caller until the thread completes execution.

You can do it yourself using NSConditionLock. Define two conditions: start and end. The worker thread receives a "run" lock and, upon completion, is unlocked with the "completed" condition. Then the connection will be to fix the “completed” lock and then unlock it “completed”.
