除了调用indexPath以外，通过其他方法以编程方式在tableView中选择行 [英] Select row in tableView programmatically by other method beside calling their indexPath

问题描述

除了使用 [NSIndexPath indexPathForRow：0 inSection：0] 方法外，如何通过其他方法调用tableView中的行？

How can I call row in tableView by using other method beside using [NSIndexPath indexPathForRow:0 inSection:0] method?

例如，tableView中的每一行都有其自己的操作键，这些操作从XML中进行检测。因此，我想使用此操作键而不是indexPath方法以编程方式选择tableVIew中的行。

For example, every row in tableView has their own "action key" that detect from XML. So, i want to select the row in tableVIew programmatically by using this "action key" instead of using indexPath method.

我已经在SO上进行搜索，但是所有方法都在调用他们的indexPath。
有人有什么主意吗？

I already search on SO but all the method are calling their indexPath. Anybody have any idea?

这些是我当前用于我的应用程序以选择tableView中的行的方法：

These are the method that I currently used for my app to select row in tableView:

-(void)viewDidAppear:(BOOL)animated;{
    NSLog(@"viewDidAppear");
    [super viewDidAppear:YES];

    // saving an NSString
    NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
    NSString *action_app = [defaults objectForKey:@"app"];
    [defaults setObject:@"closed_NewVC" forKey:@"closed_NewVC"];

    //will select row in tableView when receive key action from Push Notification
    if (([[[NSUserDefaults standardUserDefaults]objectForKey:@"app"] isEqualToString:@"a1"]) && ([AryStoreInboxItem count]>0)){

        NSIndexPath *indexPath = [NSIndexPath indexPathForRow:0 inSection:0];
        [self->tableView selectRowAtIndexPath:indexPath animated:YES scrollPosition:UITableViewScrollPositionMiddle];
        [self tableView:self->tableView didSelectRowAtIndexPath:indexPath];

    }else if (([[[NSUserDefaults standardUserDefaults]objectForKey:@"app"] isEqualToString:@"a2"]) && ([AryStoreInboxItem count]>1)){

推荐答案

何时在处理 UITableView 时，如果不使用 NSIndexPath ，最终没有可取的方法来访问或与单元交互。因此，建议您创建一个可靠的数据源，以便为单个数据/模型对象确定正确的 NSIndexPath 。

When dealing with a UITableView there's finally no advisable way to access or interact with cells without using NSIndexPath. So I'd recommend you to create a solid data source to determine the correct NSIndexPath for a single data/model object.
