ios-Nav右上角按钮

右上角的设置按钮

 //******************  右上角保存按钮  ******************
         UIButton *rightBtn = [UIButton buttonWithType:UIButtonTypeCustom];
         [rightBtn setBackgroundImage:[UIImage imageNamed:@"xiesixin.png"] forState:UIControlStateNormal];
         [rightBtn setFrame:CGRectMake(, , , )];
         [rightBtn setTitle:@"保存" forState:UIControlStateNormal];
         [rightBtn addTarget:self action:@selector(rightBtnClick) forControlEvents:UIControlEventTouchUpInside ];
         UIBarButtonItem *searchButton = [[UIBarButtonItem alloc]initWithCustomView:rightBtn];
         self.navigationItem.rightBarButtonItem = searchButton;
         self.tabBarController.hidesBottomBarWhenPushed = YES;

ms用的不是自定义NavgationController，所以需要使用到 UIBarButtonItem 来设置。
