在执行UItableView委托/数据源方法之前，控制台中显示“之前没有重用表格单元的索引路径”消息

Question

I am developing an application where I am using UITableView which is added programmatically to view as follow,

//creating tableview1
    tableView1=[[UITableView alloc]initWithFrame:CGRectMake(self.view.frame.origin.x,self.view.frame.origin.y,self.view.frame.size.width,heightOfTable1)];
    tableView1.scrollEnabled=NO;
    tableView1.dataSource=self;
    tableView1.separatorStyle=UITableViewCellSeparatorStyleNone;
    [self.view addSubview:tableView1];

following is my cellForRowAtIndexPath method

-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
    static NSString *cellIdentifier=@"CustomHiddenViewCell";
    CustomHiddenViewCell *cell = (CustomHiddenViewCell *)[tableView dequeueReusableCellWithIdentifier:cellIdentifier];
    if (cell == nil)
    {
        NSArray *nib = [[NSBundle mainBundle] loadNibNamed:@"CustomHiddenViewCell" owner:self options:nil];

        cell = [nib objectAtIndex:0];

    }

    [cell setSelectionStyle:UITableViewCellSelectionStyleNone];
    cell.greetingLabel.hidden=YES;
    cell.detailViewButton.hidden=YES;
    cell.separatorView.hidden=YES;
    cell.accessoryType=UITableViewCellAccessoryNone;

    if (tableView==tableView1) {
        [[cell viewWithTag:101] removeFromSuperview];
        [[cell viewWithTag:102] removeFromSuperview];
        [[cell viewWithTag:103] removeFromSuperview];
        [[cell viewWithTag:104] removeFromSuperview];
        [[cell viewWithTag:105] removeFromSuperview];

When I run my application it gives me "no index path for table cell being reused before" message in console. When I tried to run it with debugger I found that this message is displayed first and then it starts executing UItableView's delegate and datasource methods.

I have also tried running after removing all reload, begin update and end update statement but still I am getting this message. And this message is not shown during reload or update statement it is only shown before loading

Can anyone please tell me why this is happening? Is anything wrong in my code? Any help is appreciated.

Answer 1

Got the solution. I am getting this message just because I am reloading tableview in completion block of presentViewController of earlier view controller while presenting another view controller.

Solved this issue by removing reload statement from completion block of presentViewController
