objective-c - 如何向 UIBarButtonItem 添加图像？

Question

我创建了一个自定义按钮并将其应用于 UIbarbuttonitem。没有错误，但导航栏上没有显示任何内容:(这是我的代码-

    //create a custom button
    UIImage *image = [UIImage imageNamed:@"TESTButton.png"];
    UIButton *myCustomButton = [UIButton buttonWithType:UIButtonTypeCustom];
    myCustomButton.bounds = CGRectMake( 0, 0, image.size.width, image.size.height );    
    [myCustomButton setImage:image forState:UIControlStateNormal];
    [myCustomButton addTarget:nil action:@selector(goBack:) forControlEvents:UIControlEventTouchUpInside];


    UIBarButtonItem *button = [[UIBarButtonItem alloc] initWithCustomView:myCustomButton];
    self.navigationItem.leftBarButtonItem = button;
    self.navigationController.navigationBar.barStyle = UIBarStyleDefault;

    [button release];
    [myCustomButton release];
    [image release];
    [navID release];

谁能修复我的代码？ :)

来自 the docs:

initWithImage:style:target:action:

试试吧。
