如何让UIBarButtonItem打开一个新的视图控制器？

Question

我想添加方法，当按下这个信息按钮时打开新的视图控制器。

UIBarButtonItem *infoItem = [[UIBarButtonItem alloc] 
          initWithTitle:@"Info" 
          style:UIBarButtonItemStyleBordered 
          target:nil 
          action:@selector(action)]; 

Answer 1

-(void)action { 
    MyViewController *myView = [[MyViewController alloc] initWithNibName:@"MyViewController" bundle:nil]; 
    [myView presentModalViewController:YES]; // present view modally 
    [self.navigationController pushViewController:myView animated:YES]; // add to navigation stack 
    [myView release]; 
}
