dismissViewControllerAnimated不会解散ViewController

Question

所以....我有一个视图控制器,当我按下一个按钮时,会出现另一个视图控制器:

- (IBAction)searchButtonPressed:(id)sender {
    [self presentViewController:self.controllerSearch animated:YES completion:nil];
}

内部视图控制器编号2是一个表视图,当在表中选择一行时,此代码运行:

NSString *phrase = nil; // Document password (for unlocking most encrypted PDF files)

        NSString *filePath2 = filePath; assert(filePath2 != nil); // Path to first PDF file

        LazyPDFDocument *document = [LazyPDFDocument withDocumentFilePath:filePath2 password:phrase];

        if (document != nil) // Must have a valid LazyPDFDocument object in order to proceed with things
        {
            LazyPDFViewController *lazyPDFViewController = [[LazyPDFViewController alloc] initWithLazyPDFDocument:document];

            lazyPDFViewController.delegate = self; // Set the LazyPDFViewController delegate to self

#if (DEMO_VIEW_CONTROLLER_PUSH == TRUE)

            [self.navigationController pushViewController:lazyPDFViewController animated:YES];

#else // present in a modal view controller

            lazyPDFViewController.modalTransitionStyle = UIModalTransitionStyleCrossDissolve;
            lazyPDFViewController.modalPresentationStyle = UIModalPresentationFullScreen;

            [self presentViewController:lazyPDFViewController animated:YES completion:NULL];

#endif // DEMO_VIEW_CONTROLLER_PUSH
        }
        else // Log an error so that we know that something went wrong
        {
            NSLog(@"%s [LazyPDFDocument withDocumentFilePath:'%@' password:'%@'] failed.", __FUNCTION__, filePath2, phrase);
        }

现在我使用的是LazyPDFKit,它附带了这个委托方法:

- (void)dismissLazyPDFViewController:(LazyPDFViewController *)viewController
{
    // dismiss the modal view controller
    [self dismissViewControllerAnimated:YES completion:NULL];

}

我提出了一个断点,我可以看到我的代码进入了委托方法,但是LazyPDFViewController并没有消失.

我尝试过以下方法:

[[[self presentingViewController] presentingViewController] dismissViewControllerAnimated:YES completion:nil];

但这让我回到了几个视图控制器.

我错过了什么吗？

我的第一个视图中的附加代码Controller .h

@property (strong, nonatomic) UISearchController *controllerSearch;

并在第一视图控制器.m

- (UISearchController *)controller {

    if (!_controllerSearch) {

        // instantiate search results table view
        UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"Storyboard" bundle:nil];
        LHFileBrowserSearch *resultsController = [storyboard instantiateViewControllerWithIdentifier:@"SearchResults"];

        // create search controller
        _controllerSearch = [[UISearchController alloc]initWithSearchResultsController:resultsController];
        _controllerSearch.searchResultsUpdater = self;

        // optional: set the search controller delegate
        _controllerSearch.delegate = self;

    }
    return _controllerSearch;
}

尝试这个：

- (void)dismissLazyPDFViewController:(LazyPDFViewController *)viewController
{
    // dismiss the modal view controller
    [[viewController presentingViewController] dismissViewControllerAnimated:YES completion:nil];

}

你的代码： [[[self presentingViewController] presentingViewController] dismissViewControllerAnimated:YES completion:nil]; 太过分了。
