iphone - DetailViewController 中的 subview ？

Question

我有一个主 TableView 和一个详细 View 。当我单击单元格详细信息 View 时，应显示该项目的详细信息。现在我想做的是创建 subview 并将该 subview 放入详细 View 中，而不是为每个单元格创建详细 View 。它会解决我的一些其他问题。代码如下所示:

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {

    DetailViewController *nextController = [[DetailViewController alloc] init];

    int storyIndex = [indexPath indexAtPosition:[indexPath length] -1];

    [nextController initWithObjectAtIndex:storyIndex inArray:stories];

    NSString *storyTitle = [[stories objectAtIndex:storyIndex] objectForKey:@"title"];

    nextController.title = @"Details";

    UIBarButtonItem *tempButtonItem = [[[UIBarButtonItem alloc] init] autorelease];
    tempButtonItem.title = @"Tillbaka";
    self.navigationItem.backBarButtonItem = tempButtonItem ;

       [self.navigationController pushViewController:nextController animated:YES];

       [nextController release];
}

现在我如何创建带有标签的 subview 并将该标签的文本更改为storyTitle。提前致谢。

how can i create a subview with a label and change text of that label to storyTitle

给定一个父 View ，您不需要创建一个新的 subview 只是为了向父 View 添加标签。但是，假设您确实想向父 View 添加带有标签的 subview ，请执行以下操作:

...
UIView *parentView;
...
UIView *subView = [[[UIView alloc] initWithFrame:mySubViewFrame] autorelease];
UILabel *lbl = [[[UILabel alloc] initWithFrame:myLabelFrame] autorelease];
lbl.text = storyTitle;
[subView addSubview: lbl];
[parentView addSubview: subView];
