自定义导航栏按钮

自定义导航栏按钮

 

添加了UINavigationController后，可以在当前视图控制器修改下一页的返回按钮backBarButtonItem：

 

方法1.  用系统自带的返回按钮

UIBarButtonItem *leftBarButtonItem = [[UIBarButtonItem alloc]

                                          initWithTitle:@"返回"

                                          style:UIBarButtonSystemItemCancel

                                          target:self

                                          action:@selector(doClickBackAction:)];

    self.navigationItem.backBarButtonItem = leftBarButtonItem;

 

方法2. 自己定义返回按钮

UIImage* backImage = [UIImage imageNamed:@"btn_back.png"];

    CGRect backframe = CGRectMake(0,0,54,30);

    UIButton* backButton= [[UIButton alloc] initWithFrame:backframe];

    [backButton setBackgroundImage:backImage forState:UIControlStateNormal];

    [backButton setTitle:@"直播" forState:UIControlStateNormal];

    backButton.titleLabel.font=[UIFont systemFontOfSize:13];

    [backButton addTarget:self action:@selector(doClickBackAction:)forControlEvents:UIControlEventTouchUpInside];

    UIBarButtonItem* leftBarButtonItem = [[UIBarButtonItem alloc]initWithCustomView:backButton];

    UIBarButtonItem* leftBarButtonItem = [[UIBarButtonItem alloc] init];

    self.navigationItem.leftBarButtonItem = leftBarButtonItem;

    [leftBarButtonItem release];

    [backButton release];

其实导航栏中所有按钮都可以采用方法而进行自定义。
