我目前正在尝试在弹出框内放置一个表格视图和搜索栏,但我遇到了一个非常奇怪的错误。每当我点击搜索栏时,取消按钮就会出现动画,并且栏会立即降低到状态栏的大小。
我试过玩 UIBarPosition 委托,但这也无济于事。我已经尝试了几乎所有我能想到的东西,所以我想我会寻求你的帮助。这是我在 UITableViewController 中用于将搜索栏添加到表头的代码:
- (id)initWithStyle:(UITableViewStyle)style
{
self = [super initWithStyle:style];
if (self)
{
searchBar = [[UISearchBar alloc] initWithFrame:CGRectMake(0, 0, popoverWidth, singleRowHeight)];
searchBar.delegate = self;
searchBar.showsScopeBar= YES;
searchDisplayController = [[UISearchDisplayController alloc] initWithSearchBar:searchBar contentsController:self];
searchDisplayController.delegate = self;
searchDisplayController.searchResultsDataSource = self;
searchDisplayController.searchResultsDelegate = self;
searchDisplayController.searchResultsTableView.rowHeight = singleRowHeight;
self.automaticallyAdjustsScrollViewInsets = NO;
self.tableView.tableHeaderView = searchBar;
return self;
}
- (UIBarPosition)positionForBar:(id<UIBarPositioning>)bar
{
return UIBarPositionTop;
}
谢谢!
