uitabbar

问题 I have been unable to google an acceptable solution to this that can be applied to my project. My app is a graphing tool that has three tabs; one for the graph itself and the other two are for browse/search functions for things that can be added to the graph. All tabs are navigation controllers. The tab for the graph itself, when in portrait mode, displays a small preview of the graph and lists details of each entity that is on the graph below, and displays the tab bar at the bottom. When the

问题 I have a table based app and would like to add a tab bar to the bottom to switch between this table and other views. What is the msot hassle free way to do this ? Can I just wire in a tab view controller underneath the table view? Thanks, Martin 回答1: You actually have to load your view controllers into a UITabBarController. So if you have a tableViewController, viewController1, and viewController 2, you want to add all those to the tabBarController. UITabBarController *tabBarController = [

问题 I have a custom action sheet viewController . Which is presented modally on the current top view controller. Like this: //MARK: Static Func static func initViewController() -> CustomActionSheetViewController { let customActionSheetViewController = CustomActionSheetViewController(nibName: "CustomActionSheetViewController", bundle: nil) return customActionSheetViewController } func presentViewController<T: UIViewController>(viewController: T) { DispatchQueue.main.async { if let

问题 I’ve created a StoryBoard project and added a UITabBar to my first view and a few UITabBar items on it. I’m using a UITabBar and not a UITabBarController because the UITabBar needs to be scrollable vertically so it is inside a UIScrollView . I want to connect the UITabBar items to different ViewControllers . How do I do that inside the Interface builder? With UITabBarController it’s just a Ctrl+drag like everything else in the IB, but for some reason the UITabBar acts differently. I’m aware

问题 I am trying to change images of my tabbar in a ViewController, but to display the new images, I must click on each tab bar item. for (CustomTabBarItem *myItem in self.tabBarController.tabBar.items){ myItem.enabled = YES; myItem.badgeValue = @"1"; UIImage *myImage = [[UIImage alloc] initWithContentsOfFile:[[DesignManager sharedManager] getPathOfFile:@"test.png"]]; *myItem.imageSelect= *myImage; // change images of each item. don't appear if I dont click on the item } Anyone know How can I can

问题 I know this is a very repeat topic, but I can't get it works. MainTab.h: #import <UIKit/UIKit.h> @interface MainTab : UITabBarController<UITabBarControllerDelegate, UITabBarDelegate> { IBOutlet UITabBarController *tabController; } @property (nonatomic,retain) IBOutlet UITabBarController *tabController; @end MainTab.m - (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil { self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil]; if (self) { // Custom

问题 TvOS 13. I have a UITabBarController with tabs. And can customize almost everything except this obvious thing: focused tab's background. It's always white. Guide tells Specify tints for selected and unselected items I tried: view.backgroundColor = .purple tabBar.tintColor = .yellow tabBar.barTintColor = .red tabBar.unselectedItemTintColor = .brown tabBar.backgroundColor = .green tabBar.backgroundImage = UIColor.blue.toImage() tabBar.shadowImage = UIColor.orange.toImage() tabBar

问题 My buttons seem stretched, especially in landscape orientation. I can't find a property to adjust either on the UITabBar, UITabBarViewController, or on the UITabBarItem's themselves. (Of course, one answer would be to get an iPad...but that doesn't solve the need for a phone.) For example, consider this simple Tab Bar Example - if I only could set the tab bar to auto-shrink as more buttons are added, or manually adjust the width to fit them all on the tab bar, I would be happy. 回答1: It is not
