iOS解决多线程 线程阻塞问题

一：这样处理之后不会影响外部视图的展示，亲测可行

#import"ThreadSDK.h"

@interfaceThreadSDK(){

    BOOL threadDone;

}

@end

@implementationThreadSDK

//测试接口

- (void)thread {

    [selfperformSelector:@selector(asynchronousSource)withObject:nilafterDelay:0];

    NSLog(@"me");

   threadDone= NO;

    do {

       // Start the run loop but return after each source is handled.

       SInt32result =CFRunLoopRunInMode(kCFRunLoopDefaultMode,1,YES);

       if((result ==kCFRunLoopRunStopped) || (result ==kCFRunLoopRunFinished))

            threadDone = YES;

    } while (!threadDone);

   NSLog(@"me --- end");

}

//阻塞测试

- (void)asynchronousSource {

    for (int i = 0; i < 5; i++) {

        sleep(1);

       NSLog(@"asynchronous input source run");

    }

   threadDone= YES;

}
