Second UITabBar - ios

Question

I already looking since a hour for a solution of my problem.
A picture can tell more then thousand words:
I have two TabBars in my ViewController. The first one I created with the storyboard, and it works. Now I would like to have the second one to select the type of connection. Because every connection type has some own things to fill. I just drag and drop a new UITabTab into my ViewController, added a third TabBar item but I don't know what is next. How to handle the second TabBar. What methods do I need? How to catch touches on this items, so I can change a view?

Answer 1

You're using a UITabBarViewController or a UIViewController? I suspect the first is the case and you don't know how to hook up two of the same to one ViewController. What you need to do is to take apart the delegate methods for the UITabBar so you can do it twice in the same controller.
You should do the following:
Use a regular UIViewController
Drag two UITabBars onto the View
Connect them to your ViewController
Create two implementations of the UITabBarDelegate for each UITabBar in separate classes
At viewDidLoad or a similar event create instances of those classes and set the "delegate" of each UITabBar to that instance
Some example code
First create a new class for the bar on top. It only needs to do one thing:
#import "LVDTopTabDelegate.h"
#implementation LVDTopTabDelegate
// This is the only required part of the delegate
- (void)tabBar:(UITabBar *)tabBar didSelectItem:(UITabBarItem *)item;
{
// Handle what you wanted to do
}
#end
The second one is more or less the same
#import "LVDBottomTabDelegate.h"
#implementation LVDBottomTabDelegate
- (void)tabBar:(UITabBar *)tabBar didSelectItem:(UITabBarItem *)item;
{
// Handle what you wanted to do
}
#end
You viewDidLoad should look approximately like this:
#implementation LVDViewController
- (void)viewDidLoad;
{
LVDTopTabDelegate *topTabDelegate = [[LVDTopTabDelegate alloc] init];
self.topTabBar.delegate = topTabDelegate; // self.topTabBar is an IBOutlet for your tab bar
LVDBottomTabDelegate *topTabDelegate = [[LVDBottomTabDelegate alloc] init];
self.bottomTabBar.delegate = bottomTabDelegate;
}
#end
