i have inserted in my app a Tab Bar controller through the storyboard.
Now i need to change images of tap when they are selected.
How can help me?
Go into the storyboard and select the view controller containing the tab you want to change (not the UITabBarController). In the inspector sidebar, you can choose the selected image and the default image. The images have to be 25x25 at 1x.

I am using a show segue from a Table View cell to a "Detail View" because I am using a navigation controller, the Detail View comes by default with a left bar button to take me back to Table View. Because it is done by default, I cannot figure out how to access it, to change its propertys. More specifically it's color. I am using Swift in the most current Xcode. How do you access the default navigation bar button when using a show segue?
If I drag a Tab View Controller to the storyboard of an OS X application, the tab view buttons seem to misbehave. Can you help me understand what's going on?
Here's an minimal example of a fresh project, where I simply replaced the default empty View Controller with a new Tab View Controller:
The highlighted Tab View is shown as No Shadow Tab View by default, which means that the Tab View's style is Tabless in the Attributes Inspector.
There are also two Tab View Items below the Tab View in the Scene's list.
If I build & run, the result looks like this:
The tab controls are visible, but the tab view has no bezel. It seems like the tab buttons that are displayed are actually the two extra Tab View Items, not the native buttons of the Tab View itself.
If I change the Tab View's style to Top Tabs instead of the default Tabless, I get a bezel, but duplicate tab buttons:
And if I change it to Tabless With Bezel, the bezel is below the tab buttons, instead of properly sitting midway under the buttons:
I can't figure this out. Why are there two sets of tab buttons to start with (with the "real" one hidden by default)? The two extra Tab View Items seem to be completely redundant, but they can't be deleted.
Is there a way to have a tab bar with a proper bezel when using Interface Builder and a Tab View Controller?
You need to set the style of the tabViewController to "Unspecified" and setup the included tabView.
Is it possible to use a label at a toolbar?
I would like to display a number in a label. It is easy in a view but now I want it to be displayed in the toolbar.
I can drag a label to the toolbar, no problem, but the content is not visible there, even if the name Label is visible in the IB.
More info: If I drag a label into toolbar on an single view it works perfectly to display any text or number in the label even in the toolbar.
But the problem I seem to have is it does not work at a toolbar if the view is a scrollview!!
Buttons, bar buttons, no problem, but just the label does not show up when I run the app.
Why are the toolbar items behaving differently if the view is a scrollview?
It is better not to use a label for a toolbar but a UIBarButtonItem. Then you select in IB plain style and you can display the text in title.
I am designing an app with storyboard with minimal coding. So, I am designing everything using views and buttons without the need for header files.
What is the easiest way to change the default blue title bar color to black with minimal coding?
Select the nav controller in the left scene selector.
And click on the "Style" drop down menu and select the one you want.
Select "Navigation Controller > Navigation Bar" in the storyboard and use the attributes inspector.
Add this to your Info.plist file
In xcode storyboard, I have created a Tab Bar Controller that goes to 4 different tabs. One of the tabs is the main menu that has the same links available at the Tab bar. When I use the tab bar to move to the tabs, I do have the tab bar visible. But when I use the main menu links it goes fine to the different views but I lose the tab bar. How can I go from view to other view without losing the tab bar.
I have no header files in my project everything is done through storyboard.
You have to create a class implementation file for the view that you are using as a menu, in it you need to create a function that is called when you press the buttons. In those functions, you should call the following:
// Change 0 to the tab index that you want to display.
[self.tabBarController setSelectedIndex:0];
or
// Change theAppropriateViewController to the view controller that you want to display.
[self.tabBarController setSelectedViewController:theAppropriateViewController];
