iOS 添加导航栏两侧按钮

self.navigationItem.leftBarButtonItem = [[UIBarButtonItem alloc] initWithTitle:@"首页" style:UIBarButtonItemStyleBordered target:self action:@selector(popToRootView)] ;

    self.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc] initWithTitle:@"测试" style:UIBarButtonItemStyleBordered target:self action:@selector(test)] ;

//有时需要设置按钮大小才行

- (void)popToRootView{

    [self.navigationController popToRootViewControllerAnimated:YES];

}

- (void) test{

NSLog(@"test");

}
