Swift: How to execute an action when UITabBarItem is pressed

You should use UITabBarDelegate with method didSelectItem. Use it as any standard delegate:

class yourclass: UIViewController, UITabBarDelegate {    func tabBar(tabBar: UITabBar, didSelectItem item: UITabBarItem) {        //This method will be called when user changes tab.    }}

And do not forget to set your tab bar delegate to self in view controller.

Here is an answer to this question

Basically you do this:

• Make sure your view controller is subscribed to the UITabBarDelegate
• Set tags in IB for each tab bar item

• Implement the didSelectItem method, something like this:

  -(void)tabBar:(UITabBar *)tabBar didSelectItem:(UITabBarItem *)item {    if(item.tag == 1) {       // Code for item 1    }    else if(item.tag == 2) {       // Code for item 2    }}

This will give you access to each tab item tapped event. Hope it helps!

In Swift:

func tabBar(_ tabBar: UITabBar, didSelect item: UITabBarItem) {    if(item.tag == 1) {        // Code for item 1    } else if(item.tag == 2) {        // Code for item 2    }}

SWIFT 3

class yourclass: UIViewController, UITabBarDelegate {    func tabBar(_ tabBar: UITabBar, didSelect item: UITabBarItem) {        print("Test")    }}

And do not forget to set your tabBar delegate to self in viewDidLoad

override func viewDidLoad(){    super.viewDidLoad()    <YOUR TAB BAR NAME>.delegate = self }
