插入的无数据的view

- (UIView *)noDataView

{

    if (_noDataView == nil) {

        _noDataView = [[UIView alloc] initWithFrame:CGRectMake(15, 15, self.tableView.width-30, self.tableView.height-130)];

        _noDataView.backgroundColor = [UIColor whiteColor];

        [self.tableView insertSubview:_noDataView atIndex:0]；

        UIImageView *_imgView = [[UIImageView alloc] initWithFrame:CGRectMake((_noDataView.width-100)/2.0f, (_noDataView.height-100)/2.0f-30, 100, 100)];

        _imgView.image = [UIImage imageNamed:@"nodata_history"];

        [_noDataView addSubview:_imgView];

        UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(0, _imgView.bottom + 60, _noDataView.width, 20)];

        label.text = @"暂无数据！";

        label.textAlignment = NSTextAlignmentCenter;

        label.font = Demon_13_Font;

        label.textColor = CS_Color_DeepGray;

        [_noDataView addSubview:label];

        _noDataView.hidden = YES;

    }

    return _noDataView;

}

在得到数据的时候，判断view是否隐藏

            [self showNoDataView];

是否隐藏的方法实现：

#pragma mark 显示无数据

- (void)showNoDataView

{

    //判断数据条数是否为0，为0则提示无数据

    self.noDataView.hidden = (self.historyListArray.count == 0)?NO:YES;

}
