I have a UITabViewController inside a UINavigationController. As you can see on the image bellow the tab icons are set to system default "favorite" and "download" icons and they show properly when where looking in the storyboard.
One of the tabs has a collection view and the other has a web view with a status bar.
The problem is that when I deploy the app (to the simulator or a real device), the first time it opens the tab bar icon from the tab which is unselected doesn't show.
After i close and reopen the app the icon shows fine. The same thing happens if I select the tab.
How can I make the image appear correctly the first open after installation? What am I doing wrong?
I'm using Xcode 6 with iOS 8.2
Thank you
This is due to the selected image of the particular Tab bar item of the view controller just delete that selected image and give them programatically then connect the segue of the tab bar controller to relationship segue then it will work. And then you are supposed to use Tab bar --> Navigation controller --> view controller

So, I am still in a learning phase of iOS programming using Swift and got stuck in one issue.
I have a Tab bar controller with options in the tab bar at the bottom.
In one of the tab pages, I have table cells, on click of each, I move the user to a WebView (Embedded in a UIViewController).
On the webView I have placed a back button, which is linked to the main Tab Bar Controller through a segue.
I am able to come back to tab bar controller successfully, but after coming back the tab bar at the bottom does not show.
Also, how can I remove the "
I have attached the main.storyboard screenshot for reference.Main Storyboard flow
I got it working by using the Segue type as "Show Detail" instead of just "Show".
This is my tab bar when ever I launch my simulator.
But, when ever I click the other tab bar items, the other icons changes as shown below:
I want my tab bar icons to look like the first picture even if I click other tab bar items. Need help!
(I am new to IOS)
For custom tab bar images, you have to use a .pdf file with the dimensions of 25x25.
You can read more about this on Apple's Documentation.
I have installed my existing application in ios11 using xcode8 the navigation bar icons are displaying as expected when app is run using xcode9 the navigation bar icons are not showing but click actions are working fine. any icons in Navigation bar are missing while navigating from one controller to another controller.
If the navigation icons are not showing, but the interaction is still exists and works properly, it seems, that the problem is with image of the BarButtonItem. You can do next:
1) Try to set a system icon for BarButtonItem
2) Look at assets and fill all three resolutions (1, #2x, #3x)
3) Check the color of BarButtonItem
4) Check View Hierarchy
This issue happened to me and it was related to the ViewController segue properties. The segue kind was set to "Show Detail(e.g. Replace)" and changing it to Show(e.g. Push) did the trick. This is very weird because it used to work well on previous versions of Xcode but not on Xcode 9.3
Hope that helps!

I am developing basic navigation for my app, and am trying to implement a tab bar controller for the navigation.
I added a Tab Bar Controller and linked it to Navigation Controllers, but for some reason the items and icons don't show up. The Tab Bar works though, so when I run simulator I can switch between the views correctly, but it displays as completely blank.
What should I do to add the items and icons to it?
I have an application which has 5 tabs. I also have another view which you can access from tab3 via a selection of buttons. I will call it view 3b. View 3b populates with information based on which button the user selected in view 3. After the user puts in all the information required the app automatically takes them back to view 3. I want to add the tab bar to this view(3b) but I do not want it to have its own tab. I just want to use it so the user can navigate out of this view back to the rest of the app if they want to exit the screen early. Does anyone know how I can attach the tab bar to this screen without having a tab added for this screen. I am using Xcode 4.6.2 and am using storyboards to set up my app.
Any help would be appreciated. I've done a bit of searching but everything I find just explains how to use tabs.
Any help would be appreciated. Thanks.
It sounds like you need to use a UINavigationController.
When you set up your UITabBarController, instead of linking the third tab directly to your 3rd view controller, connect it to a UINavigationController, and then set the root view of that UINavigationController as the UIViewController you want as your third tab.
From there, you can set up your buttons to perform a push segue to your second view controller (view 3b from your question). If you do this, not only will you keep the tab bar on view 3b, but a back button will automatically be placed in the top left of the page so the user can simply go back to view 3. If you don't want the navigation bar that appears to be there, you can instead uncheck the "shows navigation bar" checkbox in the UINavigationController's attributes inspector.
I hope this helps!
