UIScrollView 自动滚动相册

假如你用UIScrollView制作了一个横向的相册，并且每页显示一张图，有点想很多网站首页的广告//广告定时任务[NSTimer scheduledTimerWithTimeInterval:2 target:self selector:@selector(scrollTimer) userInfo:nil repeats:YES];//设置滚动-(void)scrollTimer{        timerCount++;    if (timerCount >= 4) {        timerCount=0;    }    [adView setContentOffset:CGPointMake(tableWidth * timerCount, 0)animated:YES];    [pageControl setCurrentPage:timerCount];}
