NSThread的使用

-(void)creatThread1

{

    NSThread *thread =  [[NSThread alloc]initWithTarget:self selector:@selector(run:) object:@"abc"];

    thread.name = @"mythread";

    [thread start];

}

-(void)creatThread2

{

    //不要开启,无法设置线程名称

    [NSThread detachNewThreadSelector:@selector(run:) toTarget:self withObject:@"miss"];

}

-(void)creatThread3

{

    //开启后台线程

    [self performSelectorInBackground:@selector(run:) withObject:@"background"];

}

-(void)run:(id)obj{

    NSLog(@"current = %@",[NSThread currentThread]);

    for (int i = 0; i < 100000; i ++) {

        NSLog(@"--%d--",i);

    }

}

 

线程休眠

[NSThread sleepForTimeInterval:2];

[NSThread sleepUntilDate:[NSDate dateWithTimeIntervalSinceNow:2]];

 

线程退出

[NSThread exit];
