Question

我的安保行动分队为什么在主线上操作主要方法? 我希望它能够 as。

@interface ServiceClient : NSOperation
@end

@implementation ServiceClient

- (void)main
{
   if ([[NSThread currentThread] isEqual:[NSThread mainThread]])
   {
      NSLog(@"Why does this get called on the main thread");
   }
}

@end

开始运作

ServiceClient *serviceClient = [[ServiceClient aloc] init];
[serviceClient start];

- (BOOL)isConcurrent
{
   return YES;
}

Snippet taken from Concurrency Programming Guide

start
(Required) All concurrent operations must override this method and replace the default behavior with their own custom implementation. To execute an operation manually, you call its start method. Therefore, your implementation of this method is the starting point for your operation and is where you set up the thread or other execution environment in which to execute your task. Your implementation must not call super at any time.
