ios - UISearchbar searchBarTextDidEndEditing 未被调用

Question

这个问题已经有答案了:

iPhone SDK: UISearchBar: searchBarTextDidEndEditing not firing (3 个回答)

已关闭 9 年前。

所以我有这个代码 -

- (void)searchBarTextDidEndEditing:(UISearchBar *)searchBar{
    NSLog(@"SEARCH BAR TEXT DID END EDITING");
    [self handleSearchForSearchString:searchBar.text];
}

-(BOOL)searchBarShouldBeginEditing:(UISearchBar *)searchBar{
    NSLog(@"SEARCH BAR BEGIN EDITING");
    if(shouldBeginEditing) {
        NSTimeInterval animationDuration = 0.3;
        [UIView beginAnimations:nil context:NULL];
        [UIView setAnimationDuration: animationDuration];
        [UIView commitAnimations];
        [self.searchDisplayController.searchBar setShowsCancelButton: YES animated:YES];
    }
    BOOL boolToReturn = shouldBeginEditing;
    shouldBeginEditing = YES;
    return boolToReturn;
}

searchBarShouldBeginEditing正在被调用，但是 searchBarTextDidEndEditing没有被调用。为什么会发生这种情况？
