UISearchBar范围按钮的iOS可视化发生变化

Question

点击取消按钮后，示波器栏位于搜索栏旁边......但代码为：

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

我希望它保持在搜索之下，而不是在旁边！

Answer 1

这段代码一切正常：

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