ios-Nav右上角按钮

右上角的设置按钮

1 //******************  右上角保存按钮  ******************
2         UIButton *rightBtn = [UIButton buttonWithType:UIButtonTypeCustom];
3         [rightBtn setBackgroundImage:[UIImage imageNamed:@"xiesixin.png"] forState:UIControlStateNormal];
4         [rightBtn setFrame:CGRectMake(0, 0, 50, 30)];
5         [rightBtn setTitle:@"保存" forState:UIControlStateNormal];
6         [rightBtn addTarget:self action:@selector(rightBtnClick) forControlEvents:UIControlEventTouchUpInside ];
7         UIBarButtonItem *searchButton = [[UIBarButtonItem alloc]initWithCustomView:rightBtn];
8         self.navigationItem.rightBarButtonItem = searchButton;
9         self.tabBarController.hidesBottomBarWhenPushed = YES;

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