uitabbarcontroller

问题 When launching a UITabBarViewController from code in a storyboard the first view displays the navigation controller too high in the status area. Tapping the tabs corrects it, however the first view is incorrect. Do I need something else in the AppDelegate? Specific code solutions would be appreciated. Thanks - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { // Need something here??? return YES; } // initial UITabBarViewController in

问题 Basically I have a tab bar in view controller one. I am trying to detect if this tabaritem is touched inside view controller 2. What is the best method to perform such a task? I can post more specific code if you would like. view controller 1 TUHomeViewController *homeViewController = [[TUHomeViewController alloc] initWithNibName:nil bundle:nil]; UINavigationController *homeNavigationController = [[UINavigationController alloc] initWithRootViewController:homeViewController];

问题 I have set the title for all five of my tabs in my AppDelegate file. I would like to access that title in another view within my application. I have the code below to output to the log window the selected index of that selected tab but what I'd really like to get is the title for that tab. I did have a look through the UITabBarController Class Reference and I didn't see anything that would allow me to do this. What I am trying to avoid is some sort of switch or if...else statement where I

问题 I have posted a question here . In which one buddy replied and gave solution. Although the solution is working on few view controllers but on view its not working.

问题 I'm developing an iOS 5 app using Storyboard. I have UITabBarController which has 3 tabs. Every tab has its own UINavigationController . UINavigationController of first tab has one UITableViewController which segues to another UIViewController etc. UINavigationController of second tab has only one UIViewController . What I want to achieve is to navigate to UIViewController (second view in UINavigationController of first tab) when certain action happens in UIViewController of second tab. I've

问题 I've currently got a UITabBar with 5 screens calling UIViews. That part works fine but I want to put in a UINavigationController in a couple of them. I have found a few tutorials that work fine but all of them implement it in IB and I want to avoid that if possible. I'm lost as to where to implement the UINavigationController, should I do it in the App Delegate with the UITabBar and call the navigation controller from the UIView or should I create it in the UIView class? I've tried about 8

问题 I made a subclass of UITabBarController that adds a custom UIView on top of tabs to replace the default badging on a UITabBarItem. I add these custom badgeviews on viewDidLoad of my custom UITabBarController. [self.view addSubview:_tabBarItem1BadgeView]; The drawRect on my custom tabBarBadgeView looks like this: - (void)drawRect:(CGRect)rect{ CGContextRef ctx = UIGraphicsGetCurrentContext(); // Badge CGSize size = self.frame.size; CGSize badgeSize = [self sizeThatFits:size]; badgeSize.height

问题 ! am an objective c beginner.

I then tried to extend the first view with two more views: one master table view and one detail UIView. The first view is linked to the master table view through the button on the first view. I compiled to run the project, everything is smooth except the tabbar is not

问题 I have a Login project. The first view controller is NavController and I need to pass user data to tabBarController where I have 3 NavigationControllers.
