问题 I am wondering if there is a way to add an additional UITabBarItem to my exisiting UITabBarController . It doesn't need to be in runtime.

问题 I have a Tab Bar Controller with four navigation controllers added to it. The navigation controllers appear as Tab Bar Items in the Tab Bar Controller. Now I want to add a fifth button to the tab bar, that does not open another view, but triggers some custom code.

How can I do that? 回答1: I can suggest to add dummy UIViewController to the last index and handle

问题 I currently have 8 UITabBar items, all of which are editable in the More view. My question is, what is the absolute maximum number of tab bar items allowed? I understand 5 is the most that can be visible at one time; I'm looking for the most you can have period. 回答1: I don't think there is a hard limit, as long as you don't run out of memory. I've used more than 20 in the past without any problems (although having many controllers means you should be really careful when managing memory, i.e.

How to change the color of unselected tab bar items in iOS 7?

由 本秂侑毒 提交于 2019-12-06 07:54:35
Im trying to change the color of the unselected images in the tab bar, by default they are changed to gray, even if the image is another color.
