问题 There are 2 viewControllers in a navigationController: navigationController->root->A In viewController A, if a user make some settings and press the left bar button item(Back), I want the root view to renew its layout(some views' size will be changed).

问题 It's odd, I know, but even if you stated hidesBackButton to YES for the UINavigationItem associated with your view, you will be able to go back just touching the area that was meant to be a back button. Sharing my solution... (more to come) 回答1: First I thought it was a simulator bug and uploaded to the device. But when I reproduced the same behavior there as well I started to think how to get rid of such behavior (since it was essential for me). Came up to such a solution: [self

问题 Hi I have a navigationController that starts with a view controller in which in viewDidLoad has: self.navigationController.navigationBarHidden = YES; I click a button on that page and it transitions to a second view controller in which I put: self.navigationController.navigationBarHidden = NO; This works fine until I click the Back button in the navigation bar. How do I keep the navigation bar permanently off the start page but not the transitioned one? 回答1: Add self.navigationController

问题 I'm trying to use the pushViewController: animated: with a UIViewController. I have it housed in a UINavigationController with initWithRoot and it still doesn't work. Here is my code? Am I doing something wrong?

问题 I have a game with two rootViewControllers - one for the Menu and the other for the Game itself. When the user switches between the Game and the Menu, I want to switch the rootViewController. Ultimately my questions is, what is the best way to do this? Or is there another approach for switching stacks that makes more sense than having 2 rootViewControllers? As it stands, I have an instance of a navigationController in my appDelegate. When I want to switch rootViewController, I initialise a

问题 I have SendingController which push to nav stack SendingDeatilsController (which one has a TableView). User should should pick in TableView one row (it checked by Checkmark) and I would like to pass the value of this row (let it will NSString object) to the SendingController. How can I realize this behaviour in my application? And is SendingController parent for SendingDetailController (attribute parentController of SDC refers to SC) ?? 回答1: If you want to implement this behaviour, pass the

问题 I'm overwriting UINavigationController to replace the default navigationBar property with an instance of my own subclass of UINavigationBar . So I tried something like _navigationBar = [[SBNavigationBar alloc] init]; in my -initWithRootViewController: . But that didn't work out as I expected it. There's still the default navigationBar being displayed. So what's the best point to overwrite the navigationBar ? Thanks in advance –f 回答1: If you check the documentation http://developer.apple.com
