iphone - 访问模态视图 Controller 父级

Question

我正在以模态方式呈现一个 ViewController。如何访问父 View Controller ？

我的架构是TabBarController=>VC1=>VC2=>VC3=>MVC1，我想从MVC1到达VC3。

在 VC3 中，我有这样的代码:

- (void) editAd{
    AskPasswordViewController *modalViewController = [[AskPasswordViewController alloc] initWithNibName:@"AskPasswordView" bundle:nil];

    NSLog(@"modalparent class=%@", [[modalViewController parentViewController] class]);

    [self presentModalViewController:modalViewController animated:YES];
    [modalViewController release];
}

我在 MVC1 中试过这个:

- (void) sendRequest {
    NSLog(@"classe : %@",[[self parentViewController] class] );
}

但它返回我的 TabBarViewController...

Answer 1

您可以通过调用访问父级:

self.presentingViewController

根据苹果文档:

The view controller that presented this view controller (or its farthest ancestor.)
