本来在别的地方看见的。但是代码有点问题  经过修改可以用了 。这个菊花怪比较简单  用的时候只需要

//    无敌风火轮   indicator = [[MyProgressView alloc]initWithFrame:CGRectMake(0, 0, 120, 120) superView:self.view];    [indicator setMessage:@"正在努力加载,请稍候..."];        if (indicator.visible==NO) {        [indicator show:NO];    }else {        [indicator hide];    }

就可以了。什么时候想让菊花怪停下来就在那个地方让indicator hide就好了
