如何使用Objective-C在工具栏中显示图像

Question

我有一个工具栏,下面是代码; 我想添加一个显示"Tools"的图像,名为"toolsIcon.png".

以下是我的代码:

    //BottomBar 

    UIToolbar *toolbar = [[UIToolbar alloc] init];
    toolbar.frame = CGRectMake(0, self.view.frame.size.height - 44,    self.view.frame.size.width, 44);
    [self.view addSubview:toolbar];
    [toolbar release];

    //TOOLBAR ITEMS
    //button 1
    UIBarButtonItem *tools = [[UIBarButtonItem alloc]   initWithTitle:@"Tools" style:UIBarButtonItemStyleBordered target:self    action:@selector(createToolView)];
    [tools setTag:0];



    //add the buttons to the toolbar
    NSArray *buttons = [NSArray arrayWithObjects: tools,nil];
    [toolbar setItems: buttons animated:YES];
    //memory management for buttons - don't waste!
    [tools release];

您可以使用图像创建UIBarButtonItem并添加它

UIBarButtonItem* item = [[UIBarButtonItem alloc] initWithImage: yourImage style: UIBarButtonItemStyleBordered target: nil action: nil];
