iOS可视化的UISearchBar范围按钮改变

Question

在我点击取消按钮后，范围栏与搜索栏并列…但是代码是:

- (void)searchBarCancelButtonClicked:(UISearchBar *)searchBar
{
searchBar.showsScopeBar = YES;
[searchBar sizeToFit];
[searchBar invalidateIntrinsicContentSize];
[searchBar setShowsCancelButton:YES animated:YES];
tabellaCanzoni.tableHeaderView = self.searchDisplayController.searchBar;
}

我希望它在搜索框下方，而不是旁边!

Answer 1

代码运行正常后:

- (void)searchBarCancelButtonClicked:(UISearchBar *)searchBar
{
[_barraRicerca resignFirstResponder];
_barraRicerca.text = nil;
[_barraRicerca setShowsScopeBar:YES];
[_barraRicerca sizeToFit];
isFiltered=FALSE;
[tabellaVideo reloadData];
}
