添加按钮到导航栏

Question

我想在导航栏中有2个右键。应用商店是否可行，是否合法？

Answer 1

是，可以是......

self.navigationItem.rightBarButtonItems = arrayOfBarButtonItems;

Answer 2

UIButton *backButton = [[UIButton alloc] initWithFrame: CGRectMake(5.0, 25.0, 60.0, 32.0)];
    [backButton setBackgroundImage:[UIImage imageNamed:@"back_btn.png"] forState:UIControlStateNormal];
    [backButton.titleLabel setFont:[UIFont fontWithName:@"Helvetica-Bold" size:14.0]];
    [backButton setTitle:@"back" forState:UIControlStateNormal];
    [backButton addTarget:self action:@selector(back:) forControlEvents:UIControlEventTouchUpInside];
    self.navigationItem.leftBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView:backButton];
