Question

I m 在UINavigationController上添加了1架IDViewController,然后向UINavigationController提出UIPopoverController的电击。除我没有把航海排在人满前外,一切都发挥了巨大作用。我制造这样的一切:

QueryViewController *puvc = [[QueryViewController alloc] autorelease];
UINavigationController *nc = [[UINavigationController alloc] autorelease];
[nc pushViewController:puvc animated:YES];

self.popUp = [[[UIPopoverController alloc] initWithContentViewController:nc] autorelease];
[self.popUp presentPopoverFromBarButtonItem:[self.toolbarItems objectAtIndex:0] permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];
self.popUp.delegate = self;

我曾试图建立航海BarHidden = NO,但还没有显示。我认为,这部法典是我的克列斯·洛默勒:

self.contentSizeForViewInPopover = CGSizeMake(500.0, 500.0);
self.title = @"Queries";

是否有东西可以显示航海如何? 我已经参加了由我主屏幕组成的UINavigationController,这能否成为我的问题的一部分?

Answer 1

 QueryViewController *puvc = [[QueryViewController alloc] autorelease];
 UINavigationController *nc = [[UINavigationController alloc] autorelease];

或许你的法典是错误的。什么是<条码>?

页: 1 QueryViewController和NavigationController。第二种使用<代码>initWithRootViewController/code>。

QueryViewController *puvc = [[[QueryViewController alloc] init] autorelease];
UINavigationController *nc = [[[UINavigationController alloc]  initWithRootViewController:pucv] autorelease];
//[nc pushViewController:puvc animated:YES];

If you use initWithRootViewController it s not necessary to push puvc instance.

你们也可以尝试这样做(我要明确表达记忆,而不是使用自动释放)。

QueryViewController *puvc = [[QueryViewController alloc] init];
UINavigationController *nc = [[UINavigationController alloc]  initWithRootViewController:pucv];
//[nc pushViewController:puvc animated:YES];

然后,在您的法典结尾处,人们会记得已发布<代码>puvc和nc。

[puvc release];
[nc release];

P.S. Check the code because I ve written without XCode.
