Odd behavior from UITabBar where background color only shows for one tab

由 不羁的心 提交于 2020-03-26 21:53:12
问题 I am using Swift 3 and I researched various methods to set the backgroundColor color of a UITabBar . The most simple method was to change the property in the didFinishLaunchingWithOptions of the AppDelegate . When I tried to do this, the UITabBar launches with the standard color, which is not my intended result. However, when I go to the next tab, the UITabBar color gets changed to my intended color. Following this, I tried to subclass my UITabBarController and I tried to set the background

问题 I have 4 tabs in my APP for iPad . The problem is that sometimes the text is bigger than the button but i have more space to use. However, the UITabBarController doesn't use all the width for the tabBarItems . Is there an option to do it? 回答1: UITabBarController will automatically insert spaces in between. You could do two things Override UITabButton's sizeThatFits method to give it your own size Insert negative-width spaces in between For option 2, here's some sample code I used for toolbars

问题 I'm developing an iPhone app, where I have a UITabBarController that has a UINavigationController for each TabBarItem.

How to switch between UITabBarController programmatically

由 这一生的挚爱 提交于 2020-01-25 09:04:21
问题 I have an application with UITabBarController, where the first tab contains a ViewController of an HomePage. What I have to do, is to switch between the tabs (this is pretty simple: [[self tabBarController] setSelectedIndex:index]), AND to navigate through outlets of the selectedTab from the "HomePage". Just to explain myself: TabElement1--->TabElementX---->UISegmentedController:segmentY The problem is that the UISegmentedController is nil because it is not initialized yet (at least the first
