iPhone NSThread帮助

Question

我的线程遇到了一些问题。目前，showInstructions提出的视图在线程完成之前被禁用...如何在线程进行时将其设置为交互式？

提前致谢！

 [self performSelectorOnMainThread:@selector(loadEverything) withObject:self waitUntilDone:YES];


    -(void)loadEverything {    
        NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init];

        [self performSelector:@selector(showInstructions)];
        [self performSelector:@selector(loadStats)];
        [self performSelector:@selector(animate_sideBTN)];
        [self performSelector:@selector(loadNIBs)];
        [self performSelector:@selector(incrementStats)];

        [NSThread detachNewThreadSelector:@selector(loadMap) toTarget:self withObject:nil];

        [[self.view viewWithTag: 123] removeFromSuperview];
        [pool drain];
        }

Answer 1

请尝试调用 - （void）loadEverything in“performSelectorOnMainThread”并从该调用[NSThread detachNewThreadSelector：]进行操作，这些操作不会影响UI组件，[self performSelector]会影响UI组件。

我认为你应该学习一些GCD并在一个块内做相同的代码。或者使用NSOperation ......如果可能，请避免使用线程。
