Set the Segment control unselected
Either:
[mySegmentControl setSelectedSegmentIndex:-1];or:
[mySegmentControl setSelectedSegmentIndex:UISegmentedControlNoSegment];It's all in the apple docs too.Ref: http://developer.apple.com/library/ios/#documentation/uikit/reference/UISegmentedControl_Class/Reference/UISegmentedControl.html
At the start after initializing your segmentedcontrol you can use
yourSegmentControl.selectedSegmentIndex=-1;it will erase any selected index.
I hope it helps
