Question

在我的iPhone应用中，

在表格视图中

我在一个单元格中有两个标签..

textLabel是默认值。
自定义标签

数据从数组中删除很好......

这是代码..

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{

    //Get the Log Id for the sections. From Section Array
    int logID=0;
    if(indexPath.row==0)
    {
        NSLog(@"Time Array %@",timeArray);
        logID=[[[sectionArray objectAtIndex:indexPath.section] valueForKey:@"logID"] intValue];
        NSPredicate *p=[NSPredicate predicateWithFormat:@"logID==%d",logID];
        fillRows=nil;
        fillRows= [[timeArray filteredArrayUsingPredicate:p] mutableCopy];
    }



    static NSString *CellIdentifier = @"Cell";



    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    if (cell == nil) {
        cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleValue1 reuseIdentifier:CellIdentifier] autorelease];

    }



//Show Current Time.
//"If condition for not to go for Array Index Out of Bound".
if(indexPath.row<[fillRows count])
{
//Log CurrentTime    
    cell.textLabel.text=[[fillRows objectAtIndex:indexPath.row] valueForKey:@"logCurrentTime"];
    [cell.textLabel setTextColor:[UIColor whiteColor]];
//Log Duration.   
   UILabel *lblDuration=[[[UILabel alloc] initWithFrame:CGRectMake(110, 11, 60, 21)] autorelease];
   [lblDuration setTextColor:[UIColor whiteColor]];
        [lblDuration setBackgroundColor:[UIColor clearColor]];
        [lblDuration setFont:[UIFont boldSystemFontOfSize:18]];
   lblDuration.text=[[fillRows objectAtIndex:indexPath.row] valueForKey:@"logDuration"];
        [cell.contentView addSubview:lblDuration];
   }

    return cell;
}

提前致谢：）

Answer 1

答案就是这个...... 为什么从te表中删除的单元格的标签粘在单元格上......

看到我已经评论了两行代码......

where cell == nil ..

  - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
    {

        //Get the Log Id for the sections. From Section Array

        static NSString *CellIdentifier = @"Cell";



        **UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
     //   if (cell == nil) {
            cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleValue1 reuseIdentifier:CellIdentifier] autorelease];

       // }**



    /if(indexPath.row<[fillRows count])
    {
    //Log CurrentTime    
        cell.textLabel.text=[[fillRows objectAtIndex:indexPath.row] valueForKey:@"logCurrentTime"];
        [cell.textLabel setTextColor:[UIColor whiteColor]];
    //Log Duration.   
       UILabel *lblDuration=[[[UILabel alloc] initWithFrame:CGRectMake(110, 11, 60, 21)] autorelease];
       [lblDuration setTextColor:[UIColor whiteColor]];
            [lblDuration setBackgroundColor:[UIColor clearColor]];
            [lblDuration setFont:[UIFont boldSystemFontOfSize:18]];
       lblDuration.text=[[fillRows objectAtIndex:indexPath.row] valueForKey:@"logDuration"];
            [cell.contentView addSubview:lblDuration];
       }

        return cell;
    }

Answer 2

  if (cell == nil) {
        cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleValue1 reuseIdentifier:CellIdentifier] autorelease];
   }
 if(indexPath.row<[fillRows count])
 {
        [lblDuration setTextColor:[UIColor whiteColor]];
        [lblDuration setBackgroundColor:[UIColor clearColor]];
        [lblDuration setFont:[UIFont boldSystemFontOfSize:18]];
        [cell.contentView addSubview:lblDuration];

 }

试试这个..

Answer 3

使用表的委托方法作为解决方案

（void）tableView：（UITableView *）tableView commitEditingStyle：（UITableViewCellEditingStyle）editingStyle forRowAtIndexPath：（NSIndexPath *）indexPath { if（editingStyle == UITableViewCellEditingStyleDelete） {[array removeObjectAtIndex：indexPath.row]; [tableview reloadData];}}

你得到你想要的东西。
