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

iOS TabBar Image assignment

问题 If it is possible, how would you go about setting a custom image to each state (selected/not selected) of tab bar items.
