I think you have a fundamental misunderstanding of how actions and targets work. You can't check on the selectedSegmentIndex at the time of creation. It will always be 0. You have to add the target exactly once and inside the responder method, check the selectedSegmentIndex and act from there:
[segmentedControl addTarget:self action:#selector(segmentAction:) forControlEvent:UIControlEventTouchUpInside];
//...
- (void) segmentAction:(UISegmentedControl *)source {
switch (source.selectedSegmentIndex) {
case 0:
[self segmentAction0:source];
break;
case 1:
[self segmentAction1:source];
break;
case 2:
[self segmentAction2:source];
break;
}
}
