Cannot get the Segmented control on the left side of a navigation bar

I am trying to add a UISegementedCo开发者_JAVA百科ntrol to the left side of a nav bar programmatically. I can get it to show in the middle by setting the control to the titleView as shown below. The following is the code that I have

NSArray *buttonNames = [NSArray arrayWithObjects:@"One", @"Two", nil];
UISegmentedControl* segmentedControl = [[UISegmentedControl alloc]
segmentedControl.segmentedControlStyle =  UISegmentedControlStyleBar;

// instead of the following I would like to move to left side of the nav bar
self.navigationItem.titleView = segmentedControl;

Any help is appreciated.

Have you tried

[[UIBarButtonItem alloc] initWithCustomView:...]

?

To be more precise, maybe something like

UIBarButtonItem* item = [[UIBarButtonItem alloc] initWithCustomView:segmentedControl];
self.navigationItem.leftBarButtonItem = item;
[item release];
