    - (NSString *)clearTmpPics
    {
        [[SDImageCache sharedImageCache] clearDisk];
        [[SDImageCache sharedImageCache] clearMemory];//可有可无
        float tmpSize = [[SDImageCache sharedImageCache] getSize]/1024/1024;
        NSString *clearCacheName = tmpSize >= 1 ? [NSString stringWithFormat:@"%.1fMB",tmpSize] : [NSString stringWithFormat:@"%.0fKB",tmpSize * 1024];
        return clearCacheName;
    }
    clearCacheName = @“0KB”;

    - (void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex {
        if (actionSheet.tag == 1)
        {  //清理缓存
            if (actionSheet.cancelButtonIndex != buttonIndex) {
                MBProgressHUD *hud = [[MBProgressHUD alloc] initWithView:self.navigationController.view];
                [self.navigationController.view addSubview:hud];
                hud.labelText = @"正在清除缓存....";
                __weak typeof (self)weakSelf = self;
                [hud showAnimated:YES whileExecutingBlock:^{
                    // 模拟删除 要时间
                    sleep(1.0);
                } completionBlock:^{
                    [hud removeFromSuperview];
                    NSString *clearCacheName =  [weakSelf clearTmpPics];
                    [MBProgressHUD showSuccess:@"清理成功"];
                    SliderModel *model = weakSelf.dataSource[1];
                    model.content = clearCacheName;
                    [weakSelf.tableView reloadRowsAtIndexPaths:[NSArray arrayWithObjects:[NSIndexPath indexPathForRow:1 inSection:0], nil]
                                              withRowAnimation:UITableViewRowAnimationNone];
