Question

我有一个表格，我可以在UITableView中选择多行。当我按“完成”时，我希望它将这些添加到三个不同的数组中。目前它只会保存第一个选定的行。如何保存UITableView中的所有选定行？

这是我的“完成”按钮方法：

-(IBAction)songsDone:(id)sender{

    selectedName = [[NSMutableArray alloc] init];
    [selectedName addObject:video.title];

    selectedAuthor = [[NSMutableArray alloc] init];
    [selectedAuthor addObject:video.author];

    selectedLink = [[NSMutableArray alloc] init];
    [selectedLink addObject:video.thumb];

    UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"MainStoryboard" bundle:[NSBundle mainBundle]];
    SongsViewController *songsViewController = [storyboard instantiateViewControllerWithIdentifier:@"SongsViewController"];
    [self.navigationController pushViewController:songsViewController animated:YES];
}

Answer 1

将初始化代码移至ViewDidLoad方法，如下所示

- (void)viewDidLoad
{
    [super viewDidLoad];
    [selectedName addObject:video.title];
    [selectedAuthor addObject:video.author];
    [selectedLink addObject:video.thumb];
    return self;
}

并简单地添加如下所示的值

-(IBAction)songsDone:(id)sender{


[selectedName addObject:video.title];


[selectedAuthor addObject:video.author];


[selectedLink addObject:video.thumb];

UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"MainStoryboard" bundle:[NSBundle mainBundle]];
SongsViewController *songsViewController = [storyboard instantiateViewControllerWithIdentifier:@"SongsViewController"];
[self.navigationController pushViewController:songsViewController animated:YES];

}
