UIToolbar精确尺寸

发布于 2024-12-20 15:23:00 字数 336 浏览 1 评论 0原文

我正在尝试借助工具栏自定义我的导航栏。我以编程方式实现了它，如下所示：

UIToolbar* tools = [[UIToolbar alloc] initWithFrame: CGRectMake(0, 0, 100, 44.01)];

然后将其添加到我的导航栏中。问题是我在边框上有这种丑陋的效果：

navigationbar + Toolbar

我尝试更改 y 和高度值，没有结果。您有什么想法可以避免这种情况吗？

预先感谢，亚萨

I'm trying to customize my NavigationBar with the help of a toolbar.
I've implemented it programmatically as follows:

UIToolbar* tools = [[UIToolbar alloc] initWithFrame: CGRectMake(0, 0, 100, 44.01)];

and then I added it to my NavigationBar. The problem is that I have this ugly effect on the borders:

navigationbar + toolbar

I've tried to change the y and the height values, with no results.
Do you have any ideas to avoid this?

Thanks in advance, yassa

我不会这样做。
您可以通过向 navigationItem.rightBarButtonItem 添加带有 2 个按钮的视图来实现相同的效果。这很简单：

// view that will hold the buttons
UIView* container = [[UIView alloc] init];

// create 1 button and add it to the container
UIButton* button = [[UIButton alloc] init........];
[container addSubview:button];


//create 2 button and add it to the container
button = [[UIButton alloc] init.........];
[container addSubview:button];


// now create a Bar button item
UIBarButtonItem* barButtonItem = [[UIBarButtonItem alloc] initWithCustomView:container];

// set the nav bar's right button item
self.navigationItem.rightBarButtonItem = barButtonItem;

I wouldn't do it this way.
You can achieve the same effect by adding a view with 2 buttons to the navigationItem.rightBarButtonItem. it is very simple:

// view that will hold the buttons
UIView* container = [[UIView alloc] init];

// create 1 button and add it to the container
UIButton* button = [[UIButton alloc] init........];
[container addSubview:button];


//create 2 button and add it to the container
button = [[UIButton alloc] init.........];
[container addSubview:button];


// now create a Bar button item
UIBarButtonItem* barButtonItem = [[UIBarButtonItem alloc] initWithCustomView:container];

// set the nav bar's right button item
self.navigationItem.rightBarButtonItem = barButtonItem;

我部分同意之前的回答和评论。
您建议的解决方案适用于自定义按钮。但是如果我想实现标准的编辑按钮怎么办？
对标准按钮/图标的访问是通过 UIBarButtonItem 类，而不是 UIButton。并且您无法将 UIBarButtonItem 对象添加到 UIView。

经过在网上进行大量研究后，我找到了完全满足我的要求的解决方案。工具栏必须按以下方式创建：

UIToolbar *tools = [[UIToolbar alloc] initWithFrame:CGRectMake(0.0f, 0.0f, 95.0f, 44.01f)];
tools.tintColor = self.navigationController.navigationBar.tintColor;
tools.barStyle = -1;

这就是结果：

my工具栏

希望它有所帮助！

I partially agree with previous answers and comments.
The solution you suggested works fine for custom buttons. But what if I want to implement standard Edit button?
Access to the standard buttons/icons is through the UIBarButtonItem class, not UIButton. And you can't add UIBarButtonItem objects to a UIView.

After many research on the web, I've found the solution that completely cover my requirement. The toolbar must be created in the following way:

UIToolbar *tools = [[UIToolbar alloc] initWithFrame:CGRectMake(0.0f, 0.0f, 95.0f, 44.01f)];
tools.tintColor = self.navigationController.navigationBar.tintColor;
tools.barStyle = -1;

And this is the result:

my toolbar

Hope it helps!

或者你也可以用这种方式来做。
只需像这样创建 UIToolbar 的新子类

   @interface MyToolbar : UIToolbar

    @end

    @implementation MyToolbar

    - (id)initWithFrame:(CGRect)frame {

        if ((self = [super initWithFrame:frame])) {

            self.opaque = NO;
            self.backgroundColor = [UIColor clearColor];
            self.clearsContextBeforeDrawing = YES;      
        }
        return self;
    }


    - (void)drawRect:(CGRect)rect {
        // do nothing
    }

    - (void)dealloc {
        [super dealloc];
    }

@end

并将其用作普通 UIToolbar 即可。我不知道为什么，但它确实有效。

Or you can do it in this way.
Just create new subclass of UIToolbar like this

   @interface MyToolbar : UIToolbar

    @end

    @implementation MyToolbar

    - (id)initWithFrame:(CGRect)frame {

        if ((self = [super initWithFrame:frame])) {

            self.opaque = NO;
            self.backgroundColor = [UIColor clearColor];
            self.clearsContextBeforeDrawing = YES;      
        }
        return self;
    }


    - (void)drawRect:(CGRect)rect {
        // do nothing
    }

    - (void)dealloc {
        [super dealloc];
    }

@end

And use it as normal UIToolbar. I don't know why but it just works.
