Question

我想将带有图像的条形按钮项目更改为另一个条形按钮，其中包含不同的图像并执行不同的功能。有什么帮助吗？

Answer 1

在代码块中使用这样的内容：

UIImage *buttonImage = [UIImage imageNamed:@"customImage.png"];// set your image Name 
        UIButton *btn = [UIButton buttonWithType:UIButtonTypeCustom];
        [btn setImage:buttonImage forState:UIControlStateNormal];
        btn.frame = CGRectMake(0, 0, bImage.size.width, bImage.size.height);
        UIBarButtonItem *barButton = [[UIBarButtonItem alloc] initWithCustomView:btn];

        self.navigationItem.barButtonItem = barButton;

Answer 2

尝试此代码，它是导航栏中图像栏按钮的自定义视图

UIImage* image3 = [UIImage imageNamed:@"mail-48_24.png"];
    CGRect frameimg = CGRectMake(0, 0, image3.size.width, image3.size.height);
    UIButton *someButton = [[UIButton alloc] initWithFrame:frameimg];
    [someButton setBackgroundImage:image3 forState:UIControlStateNormal];
    [someButton addTarget:self action:@selector(sendmail)
         forControlEvents:UIControlEventTouchUpInside];
    [someButton setShowsTouchWhenHighlighted:YES];

    UIBarButtonItem *mailbutton =[[UIBarButtonItem alloc] initWithCustomView:someButton];
    self.navigationItem.rightBarButtonItem=mailbutton;
    [someButton release];
