uitabbaritem

问题 My app is based on a tab bar architecture.

When my app launches, I can see the 4 tabs. But in fact only the first one loads its view controller. The others wait for user click to be loaded. Tabs title can be changed using [self setTitle:@"Mouhahaha"]; in viewDidLoad of loaded view controller. If I want to keep my

问题 This application I'm writing has a problem. I'm setting up the UITabBar in my application window and set the icons in the view files. But when i run the app, the first icons show up (because the view is loaded I guess) and the other icons do not show up until I click them. Do i need to implement self.tabBarItem in some other method not viewDidLoad ?

问题 My UITabBarController contains more than 16 view controllers. When I go in the "More" tab, I can see all the UITabBarItems . If I click the "Edit" button, I can see the 16 first icons, but there is not enough room to display more, so starting from the 17th item, the icons are only partially displayed.

问题 just found out something: If you have a Tabbar combined with a NavigationController (that has some views on it's stack) and you double click the TabBarItem, the view pops to the first ViewController, whether you like it or not.

If you really want to do it, you should implement the UITabBarController

问题 Can somebody tell me please how can I move title of UITabBarItem for example 2px to top? 回答1: Solution: UITabBarItem *item = [tabBar.items objectAtIndex:0]; item.titlePositionAdjustment = UIOffsetMake(0, -5.0); 回答2: Update for Swift 3 Put this code inside UITabBarController : UITabBarItem.appearance().titlePositionAdjustment = UIOffset(horizontal: 0, vertical: -5) Credit goes to Tim Brown 回答3: Swift 4 Like me, if you are creating tab bar controller inside some other controller just after
