数组在表格视图单元格中显示重复的对象 [英] Array displaying repeated object in table view cell

问题描述

我的NSArray大小为11，如下所示.

I am having a NSArray of size 11 as it formed below.

labels = [NSMutableArray arrayWithObjects:@"DIN#"，@品牌名称"，@全名"，@力量"，@药物类型"，@"Presciption ID"，@下一个剂量"，@所需剂量"，@"ada"，@"dasdada"，@"dasdasad"，nil];

但是当我在tableview单元格中显示此数组时，使用此代码.

but when i am displaying this array in tableview cell Using this code.

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {static NSString *CellIdentifier = @"Cell";
  UITableViewCell *cell = [tableView dueueReusableCellWithIdentifier:CellIdentifier];   
UILabel* nameLabel = nil;

if(cell == nil) {   cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];nameLabel = [[UILabel alloc] initWithFrame:CGRectMake( 7.0, 10.0, 160.0, 44.0 )];

    nameLabel.text =[labels objectAtIndex:indexPath.row]; 


    nameLabel.lineBreakMode = UILineBreakModeWordWrap;

    nameLabel.numberOfLines =0;
    [nameLabel sizeToFit];
    CGSize expectedlabelsize = [nameLabel.text sizeWithFont:nameLabel.font constrainedToSize:nameLabel.frame.size lineBreakMode:UILineBreakModeWordWrap];
    CGRect newFrame =nameLabel.frame;
    newFrame.size.height =expectedlabelsize.height;


   [cell.contentView addSubview: nameLabel];

return cell;}

O/P如下.

DIN

品牌名称

全名

强度

药物类型

沉淀ID

下一剂

所需剂量

DIN

品牌名称

全名

再次查看所需剂量，显示，已经显示的DIN，品牌名称，全名

推荐答案

使用 viewWithTag 方法，而我在以下方法中使用了它.尝试这样.我认为这将对您有所帮助.

Use viewWithTag method and i have used it following method. Try like this. I think it will be helpful to you.

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

    static NSString *CellIdentifier = @"myCell";
    UILabel* nameLabel = nil;
    UITableViewCell *cell = (UITableViewCell *)[tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    if(cell == nil)
    {

        cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];

    }
    else
    {
        UILabel *titleLbl = (UILabel *)[cell viewWithTag:1];
        [titleLbl removeFromSuperview];
    }
    nameLabel = [[UILabel alloc] initWithFrame:CGRectMake( 7.0, 10.0, 160.0, 44.0 )];
    nameLabel.text = [labels objectAtIndex:indexPath.row];

    nameLabel.lineBreakMode = UILineBreakModeWordWrap;
    nameLabel.tag =1;
    nameLabel.numberOfLines =0;
    [nameLabel sizeToFit];
    CGSize expectedlabelsize = [nameLabel.text sizeWithFont:nameLabel.font constrainedToSize:nameLabel.frame.size lineBreakMode:UILineBreakModeWordWrap];
    CGRect newFrame =nameLabel.frame;
    newFrame.size.height =expectedlabelsize.height;
    [cell.contentView addSubview: nameLabel];
    return cell;
}
