uitabbar

问题 Just like the tabbar, I want to show badge on UISegmentedControl . As I cant see any predefined methods for UISegmentedControl just like available for UITabBar . I thought about adding the badge as an image just on top of it, but maybe there is some better way. 回答1: Here is a little third party library I've used to draw badges on various things. It's pretty nice. For example, changing the color of the badge to match my design was trivial. Once you bring this class into your project and

问题 I am trying to put a UITabBar on a Rootviewcontroller.xib to a Navigation based Application. I know that we used navigation based applicaitons for Tableviews and by default those .xib consists of a tableview. I tried to put a UITabBar in the bottom of rootview but it is not setting over there. I saw that if we used viewbased application or a window based application we can arrange both UITabBar and UITableView on the same view. What I want to know here is: 1) Can we place a UITabBar in

This doesn't seem settable in the .xib or programmatically. Will I have to subclass the UITabBar and roll my own? 回答1: Roll your own.

问题 Can anyone please tell me how to set the default tab when using storyboards in iOS. I can't seem to figure out how to accomplish this. Thank you 回答1: You can use one of these two methods: tabBar.items = tabBarItems; tabBar.selectedItem = [tabBarItems objectAtIndex:0]; or a direct method from the object [tabBar setSelectedItem:myUITabBarItem]; or you can combine them to do this: tabBar.items = tabBarItems; [tabBar setSelectedItem:[tabBarItems objectAtIndex:0]]; but i havent tested that method
