How to handle events with multiple control segments in one view

Question

There are two segmental controls in my viewcontroller. How can I handle the tap events of both segmented controllers?

Answer 1

Set the tag property for each segmental control for another integer. Then, in your method, which you set as an action, when the value changes, check the integer value of the tag property using [sender tag] .

Answer 2

There are two ways to do this.

• Add different actions for each segment management

• Add the same actions for each segment control and check which control is used with its tag.

   [yourSegmentedControl addTarget:self action:@selector(segmentSwitch:) forControlEvents:UIControlEventValueChanged]; 

  
  

   - (IBAction)segmentSwitch:(id)sender { UISegmentedControl *segmentedControl = (UISegmentedControl *) sender; if(segmentedControl.tag == someTag) { if(segmentedControl.selectedSegmentIndex == 1) { // your code } else if(segmentedControl.selectedSegmentIndex == 2) { // your code } } else if(segmentedControl.tag == someTag) { if(segmentedControl.selectedSegmentIndex == 1) { // your code } else if(segmentedControl.selectedSegmentIndex == 2) { // your code } } } 

Answer 3

Apple docs says:

http://developer.apple.com/library/IOs/#documentation/UIKit/Reference/UISegmentedControl_Class/Reference/UISegmentedControl.html

You register target action methods for the segmented control using the UIControlEventValueChanged constant, as shown below.

 [segmentedControl addTarget:self action:@selector(action:) forControlEvents:UIControlEventValueChanged]; 

So, you just need to register an action for each segmented control.

Answer 4

You can use the selected segment mode:

 UISegmentedControl *tempSegment = sender; if ([tempSegment selectedSegmentIndex] == 0){ //first Action } else if ([tempSegment selectedSegmentIndex] == 1){ //second Action } 

Answer 5

Assign two different actions to these segmented controls:

 [segmentedControl addTarget:self action:@selector(action:) forControlEvents:UIControlEventValueChanged]; 

Answer 6

Quick version:

  @IBAction func yourFunctionName(sender: UISegmentedControl) { if (sender.selectedSegmentIndex == 0){//choice 1 }else{//choice 2 } }
