Question

我在cellForRowAtIndexPath之外访问细胞标签时遇到问题。首先在cellForRowAtIndexPath我隐藏cell.lblempName.hidden = YES;

以下是我的代码：

- (void)viewDidLoad {
     [super viewDidLoad];
     self.tblemplist.tableFooterView=self.footerView;
}


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

    static NSString *CellIdentifier = @"Cell";
    EmployeeCell *cell = (EmployeeCell *) [aTableView dequeueReusableCellWithIdentifier:CellIdentifier];

    if (cell == nil) {

        NSArray *topLevelObjects = [[NSBundle mainBundle] loadNibNamed:@"EmployeeCell" owner:self options:nil];

        for (id currentObject in topLevelObjects){
            if ([currentObject isKindOfClass:[UITableViewCell class]]){
                cell =  (EmployeeCell *) currentObject;

                cell.backgroundColor=[UIColor clearColor];
            }
        }

    }

     NSMutableDictionary *detailsdict=[empArray objectAtIndex:indexPath.row];

     cell.lblTitle.text = [detailsdict objectForKey:@"empTitle"];
     cell.lblItemprice.text = [detailsdict objectForKey:@"empId"];
     cell.lblempName.hidden = YES;

}

在页脚中我添加了一个视图并放置了一个按钮。当我点击按钮lblempName应该取消隐藏。

- (IBAction)btnApplyClicked:(id)sender {

    // How to unHide cell.lblempName.hidden = NO;

}

请帮我找到解决方案。 TIA

Answer 1

EmployeeCell *cell = (EmployeeCell *)[self.tableView cellForRowAtIndexPath:indexPath];
UILabel *label = cell.lblempName;
label.hidden = NO;

但更好的是修改你的数据，因为一旦单元格滚出视图并再次返回，标签将再次可见，因为它将再次构建。

Answer 2

创建一个bool属性BOOL isEmpNameHidden;

在 viewDidLoad 中，设置isEmpNameHidden = YES;

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

    //Your existing code here
    ....

    cell.lblempName.hidden = isEmpNameHidden;
}

然后根据按钮点击取消隐藏

- (IBAction)btnApplyClicked:(id)sender {

     isEmpNameHidden = NO;
     [self.tblemplist reloadData]

}

访问cellForRowAtIndexPath之外的单元格标签，即按钮操作目标C.
