如果有人遇到这篇文章：

Here's how to do it in code if anyone comes across this post:

UIBarButtonItem *leftButton = [[[UIBarButtonItem alloc] initWithTitle:@"Item" style:UIBarButtonItemStyleBordered target:self action:@selector(btnItem1Pressed:)] autorelease];

UIBarButtonItem *flex = [[[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:self action:nil] autorelease];

UIBarButtonItem *rightButton = [[[UIBarButtonItem alloc] initWithTitle:@"Item" style:UIBarButtonItemStyleBordered target:self action:@selector(btnItem2Pressed:)] autorelease];


self.toolbarItems = [NSArray arrayWithObjects: leftButton, flex, rightButton, nil];
