在导航栏上使用Bar Button项目

Question

如何在导航栏上实现Bar Button项目，使用我想要导航到另一个页面的Bar Button项目，因为我是iphone开发的新手，请寻求您的帮助。 提前致谢

Answer 1

UIBarButtonItem *rightBarButton = [[UIBarButtonItem alloc] initWithTitle:@"title" style:UIBarButtonItemStylePlain target:self action:@selector(btnAction)];
    [self.navigationItem setRightBarButtonItem:rightBarButton];
    [rightBarButton release];

Answer 2

试试这个：

UIButton *btnPrev =[[UIButton alloc] init];
    [btnPrev setBackgroundImage:[UIImage imageNamed:@"btnPrevious.png"] forState:UIControlStateNormal];
    btnPrev.frame = CGRectMake(100, 100, 50, 30);
    [btnPrev addTarget:self action:@selector(backButtonClicked) forControlEvents:UIControlEventTouchUpInside];


    UIBarButtonItem *btnBack =[[UIBarButtonItem alloc] initWithCustomView:btnPrev];
    self.navigationItem.leftBarButtonItem = btnBack;
