问题 Imagine that we have multiview apllication which is controlled by Navigation Controller. We go from the first view to second by using pushViewController method and that's not a problem but then we need to move to the third view. And the third one is a view which looks like a TabBar. How do we do that? The third view is supposed to be controlled by TabBarController, isn't it? So how to pass the control? I declared an outlet UITabBarController * tbc and connected it to TabBarController in xib

问题 How can I update the badgeValue of a TabBarItem when I do not exactly know the index of it? It might be in the "More" tab or on the main Tabbar depending on what the user sets.. Also if the tabbaritem is inside "More" I can only add a badgeValue to the More item right? How can I add the badge on the item itself in the tableview which is created automatically by the SDK? 回答1: Yes you can, and you don't have to know index: @implementation SomeController ... -(void)increaseBadgeValue{ NSString

问题 I've spent a while looking for a solution to this but haven't found one. I'd like to create a Tab Bar Controller with a navigation bar which is present in all child views. From what i gather, the hierarchy does not allow this, as a tab bar is (equal?) or higher in the hierarchy than a Navigation Controller, and therefor the only simple implementation is to embed each child view of the Tab Bar Controller in a Navigation Controller, like this: I was wondering if there is any technical reason

问题 I've been trying to find the solution to this for the last week, and I have had no luck after trying every possible solution I could find or think of. Every solution I found and have attempted has not worked. I have 4 UITabBarItem's in a UITabBar placed within UITabBarController. I want to put individual background color (OR image) of the UITabBarItem. Screen shot is attached I am using Swift, and iOS SDK 9.3 in Xcode 8.0. If you can only answer in Objective-C that is fine too, any answer

问题 The user logs in and lands on viewNumOne, they fill out their name and address and get to see viewNumTwo and viewNumThree. They now logout. When they log back in I want them to go straight to viewColorBlue (this is where I am having the problem). (Login Screen) View Controller with login fields. Once logged in they go to the rootVC which is a TabBar and they land on the first tab which is viewNumOne (this works fine) (Root) TabBar: (First Tab - tabBar[0]) viewNumNavController > viewNumOne

问题 I have an app that starts with a basic view controller at the root of my navigation controller - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { self.navController.viewControllers = [NSArray arrayWithObject:[self getHomeViewController]]; [[self getWindow] addSubview:self.navController.view]; [[self getWindow] makeKeyAndVisible]; return YES; } Once a navigation item is selected I push a tab bar controller w/ a few view controllers. -

问题 I'm facing this issue when I'm calling AdMob ad with [rootController.view addSubview:adMobAd]; //setup the ad Upon returning from the ad being clicked the AdMob frame moves down 20 pixels. However it seems that this is not a AdMob issue, but a issue that is also discussed here: https://discussions.apple.com/thread/2288486 However I couldn't get it to work, any ideas? 回答1: 20 pixels is the height of the status bar. If the app will don't use the status bar make sure all the XIB files you are
