How to handle events of multiple segmented control in a single view - iphone

Question

I have 2 segmented controls in my viewcontroller view. How can I handle the tap events of both of the segmented controllers?

Answer 1

There are two ways to do so.
Add different actions for every segment control
Add same actions for every segment control & check which control is tapped using 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 2

Apple docs says:
http://developer.apple.com/library/IOs/#documentation/UIKit/Reference/UISegmentedControl_Class/Reference/UISegmentedControl.html
You register the target-action methods for a segmented control using the UIControlEventValueChanged constant as shown below.
[segmentedControl addTarget:self
action:#selector(action:)
forControlEvents:UIControlEventValueChanged];
So, you just have to register action for every segmented control.

Answer 3

Set the tag property on each segmented control to a different integer. Then in your method you set as the action for when the value changes, check which integer the tag property is set to using [sender tag].

Answer 4

You can use selected mode of segment:
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

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