在navigationBar中间的按钮 [英] Button in the middle of navigationBar

问题描述

我想创建一个自定义导航栏。

I want to create acustom navigation bar.

我知道我们可以在导航栏中间使用UIButton而不是标题，但是我们可以制作一些看起来像这张照片？

I know that we can use UIButton in the middle instead of title in the navigation bar, but can we make something that look like this picture?

如你所见，我们在这个导航栏的中间有三个不同的按钮。您能否与我分享您的想法我们如何在iPhone中实现这样的事情？

As you see we have three different buttons in the middle of this navigation bar. Can you share your idea with me how we can implement such a thing in iPhone?

推荐答案

假设您使用的是导航控制器可以将navigationBar的titleView属性设置为UIView容器，该容器包含中间的三个按钮（以及两组三个点）。代码看起来像这样：

Assuming you are using a Navigation Controller you can set your navigationBar's titleView property to a UIView container that holds the three buttons in the middle (and the two sets of three dots). The code would look like something like this:

    UIView *buttonContainer = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 200, 44)];
    buttonContainer.backgroundColor = [UIColor clearColor];
    UIButton *button0 = [UIButton buttonWithType:UIButtonTypeCustom];
    [button0 setFrame:CGRectMake(0, 0, 44, 44)];
    [button0 setBackgroundImage:[UIImage imageNamed:@"button0.png"] forState:UIControlStateNormal];
    [button0 addTarget:self action:@selector(button0Action:) forControlEvents:UIControlEventTouchUpInside];
    [button0 setShowsTouchWhenHighlighted:YES];
    [buttonContainer addSubview:button0];

    //add your spacer images and button1 and button2...

    self.navigationItem.titleView = buttonContainer;  

或者你当然可以在IB中完成这一切。

Or you could do this all in IB of course.
