У меня есть простой UISearchBar с кнопкой отмены.Когда я вызываю следующее:
- (void)searchBarCancelButtonClicked:(UISearchBar *)sBar {
sBar.text = nil;
[sBar resignFirstResponder];
}
и наблюдаю его с точками останова, я получаю следующую ошибку (которая возникает после вызова [sBar resignFirstResponder]):
*** -[CFString class]: message sent to deallocated instance 0x5ec7270
This ТОЛЬКО происходит после того, как я выполнил поиск по следующему коду:
- (void)searchBarSearchButtonClicked:(UISearchBar *)sBar{
[sBar resignFirstResponder];
BrowseViewController *browseViewController = [[BrowseViewController alloc] initWithSearchTerms:sBar.text];
browseViewController.title = @"Search Results";
[self.navigationController pushViewController:browseViewController animated:YES];
[browseViewController release];
}
и вернемся к поиску.
Есть какие-нибудь идеи?
