在UITableView Objective C

Question

在UITableView中加载动态数据。我在RadioButtons(groupButtons)和btnPaul中有2 btnAdam UITableView和label(lblCheckStatus)标题为Paul和Adam。如果[cell.btnPaul setSelected:YES]; btnPaul.titlelebel.text应该标记，即保罗和[cell.btnPaul setSelected:NO];标签在UITableView中应为空。我已尝试过followign代码，但无法获得正确的响应获取null值。 TIA

// cellForRowAtIndexPath:

NSMutableDictionary* respDict = [respnseArray objectAtIndex:indexPath.row];

NSString *str = [respDict objectForKey:@"Name"];

if ([str isEqualToString:@"Paul"]) {
    [cell.btnPaul setSelected:YES];
} else {
    [cell.btnAdam setSelected:YES];
}

cell.btnPaul.tag = +indexPath.row;
[cell.btnPaul addTarget:self action:@selector(btnCheckClicked:) forControlEvents:UIControlEventTouchUpInside];

cell.btnPaul.tag = +indexPath.row;
[cell.btnPaul addTarget:self action:@selector(btnCheckClicked:) forControlEvents:UIControlEventTouchUpInside];

// RadioButton Checked
- (IBAction)btnCheckClicked:(RadioButton *)sender {

    UIButton *btn = (UIButton *)sender;
    NSUInteger tag = btn.tag;

    static NSString *CellIdentifier = @"Cell";

    FriendsCell *cell = (FriendsCell *) [_btlFriends dequeueReusableCellWithIdentifier:CellIdentifier];

    cell.lblCheckStatus.text = sender.titleLabel.text;

    NSLog(@"%@",cell.lblCheckStatus.text);
}

Answer 1

首先，在设置单选按钮标记时删除+。

cell.btnPaul.tag = indexPath.row;
[cell.btnPaul addTarget:self action:@selector(btnCheckClicked:) forControlEvents:UIControlEventTouchUpInside];

然后使用标记获取indexPath。当您使用indexPath时，您可以访问单元格，也可以访问单元格组件。希望这会对你有所帮助。

- (IBAction)btnCheckClicked:(RadioButton *)sender {

    NSIndexPath *indexPath = [NSIndexPath indexPathForRow:[sender tag] inSection:0];
    FriendsCell *cell = [_btlFriends cellForRowAtIndexPath:indexPath];

    cell.lblCheckStatus.text = cell.btnPaul.titleLabel.text;

    NSLog(@"%@",cell.lblCheckStatus.text);
}
