在UIButton上左对齐图像和中心文本

时间：2012-06-08 19:20:35

标签： ios uiimage uibutton

我见过有关正确对齐的帖子，但我无法让左对齐工作。我希望按钮占据屏幕的宽度，左边的图像和中间的标题/文字。

这不起作用（至少可靠）：

    button.titleLabel.textAlignment = UITextAlignmentCenter;
    [button setImageEdgeInsets:UIEdgeInsetsMake(0, -60.0, 0, 0)];
    button.frame = CGRectMake((self.view.frame.size.width - w ) / 2, self.view.frame.size.height - 140.0,  self.view.frame.size.width - 10.0, 40.0);

此解决方案适用于Swift 3并尊重原始内容和图像边缘插入，同时保持标题标签始终位于可用空间的中心，这样可以更轻松地调整边距。

它会覆盖@IBDesignable class LeftAlignedIconButton: UIButton { override func titleRect(forContentRect contentRect: CGRect) -> CGRect { let titleRect = super.titleRect(forContentRect: contentRect) let imageSize = currentImage?.size ?? .zero let availableWidth = contentRect.width - imageEdgeInsets.right - imageSize.width - titleRect.width return titleRect.offsetBy(dx: round(availableWidth / 2), dy: 0) } } 方法并返回正确的框架：

layoutSubviews

以下内容：

会导致：

弃用之前的回答

这适用于大多数情况，但有些布局会导致@IBDesignable class LeftAlignedIconButton: UIButton { override func layoutSubviews() { super.layoutSubviews() contentHorizontalAlignment = .left let availableSpace = UIEdgeInsetsInsetRect(bounds, contentEdgeInsets) let availableWidth = availableSpace.width - imageEdgeInsets.right - (imageView?.frame.width ?? 0) - (titleLabel?.frame.width ?? 0) titleEdgeInsets = UIEdgeInsets(top: 0, left: availableWidth / 2, bottom: 0, right: 0) } } 以无限循环递归调用自身，因此谨慎使用。

@IBDesignable
class RightAlignedIconButton: UIButton {
    override func layoutSubviews() {
        super.layoutSubviews()
        semanticContentAttribute = .forceRightToLeft
        contentHorizontalAlignment = .right
        let availableSpace = UIEdgeInsetsInsetRect(bounds, contentEdgeInsets)
        let availableWidth = availableSpace.width - imageEdgeInsets.left - (imageView?.frame.width ?? 0) - (titleLabel?.frame.width ?? 0)
        titleEdgeInsets = UIEdgeInsets(top: 0, left: 0, bottom: 0, right: availableWidth / 2)
    }
}

此代码会执行相同操作，但将图标与右边缘对齐：

semanticContentAttribute

enter image description here

正确的分配版本使用$a = array(''); $a = array_values($a); print_r($a); ，因此需要iOS 9 +。

在我的最后，我使用UIEdgeInsetsMake做了这个，计算左角到达中心。我不确定是否有什么东西可以使文本在中心对齐，但这对我有用。确保通过计算宽度将左角设置到所需位置。例如UIEdgeInsetsMake(0.0f, 42.0f, 0.0f, 0.0f) 

UIButton *scanBarCodeButton = [UIButton buttonWithType:UIButtonTypeRoundedRect];
scanBarCodeButton.frame = CGRectMake(center, 10.0f, fieldWidth, 40.0f);
[scanBarCodeButton setImage:[UIImage imageNamed:@"BarCodeIcon.png"] forState:UIControlStateNormal];
[scanBarCodeButton setTitle:@"Scan the Barcode" forState:UIControlStateNormal];
scanBarCodeButton.titleEdgeInsets = UIEdgeInsetsMake(0.0f, 42.0f, 0.0f, 0.0f);
[scanBarCodeButton setContentHorizontalAlignment:UIControlContentHorizontalAlignmentLeft];
[scanBarCodeButton addTarget:self action:@selector(scanBarCode:) forControlEvents:UIControlEventTouchUpInside];
[self.view addSubview:scanBarCodeButton];

输出看起来像，

centered text with image http://i43.tinypic.com/33mbxxi.png

在 Swift ：

var scanBarCodeButton: UIButton = UIButton(type: .roundedRect)
scanBarCodeButton.frame = CGRectMake(center, 10.0, fieldWidth, 40.0)
scanBarCodeButton.setImage(UIImage(named: "BarCodeIcon.png"), for: UIControlStateNormal)
scanBarCodeButton.setTitle("Scan the Barcode", for: UIControlStateNormal)
scanBarCodeButton.titleEdgeInsets = UIEdgeInsetsMake(0.0, 42.0, 0.0, 0.0)
scanBarCodeButton.contentHorizontalAlignment = .left
scanBarCodeButton.addTarget(self, action: "scanBarCode:", for: UIControlEventTouchUpInside)
self.view.addSubview(scanBarCodeButton)

对于Swift 4.0，这是一个有效的扩展 - 

extension UIButton {
    func leftImage(image: UIImage, renderMode: UIImageRenderingMode) {
        self.setImage(image.withRenderingMode(renderMode), for: .normal)
        self.imageEdgeInsets = UIEdgeInsets(top: 0, left: 0, bottom: 0, right: image.size.width / 2)
        self.contentHorizontalAlignment = .left
        self.imageView?.contentMode = .scaleAspectFit
    }

    func rightImage(image: UIImage, renderMode: UIImageRenderingMode){
        self.setImage(image.withRenderingMode(renderMode), for: .normal)
        self.imageEdgeInsets = UIEdgeInsets(top: 0, left:image.size.width / 2, bottom: 0, right: 0)
        self.contentHorizontalAlignment = .right
        self.imageView?.contentMode = .scaleAspectFit
    }
}

用法：

myButton.rightImage(image: UIImage(named: "image_name")!, renderMode: .alwaysOriginal)
myButton.leftImage(image: UIImage(named: "image_name")!, renderMode: .alwaysOriginal)

renderMode可以是.alwaysTemplate或.alwaysOriginal。此外，myButton应为custom类型UIButton。

这个扩展程序的leftImage和rightImage也可以UIButton UIBarButtonItem用于UINavigationBar（注意：从iOS 11开始，导航栏如下autolayout所以你需要为UIBarButtonItem添加宽度/高度约束。要在导航栏上使用，请确保遵循Apple推荐的@ 2x和@ 3x图像尺寸（即50x50,75x75），并在iPhone 6,7,8,6s，7s，8s，Plus版本和iPhone上具有更好的可访问性x UIBarButton的宽度和高度可以是高度 - 25和宽度 - 55（或者您的应用需要的任何数字，这些数字是一些基本数字，适用于大多数情况）。

更新：在Swift 4.2中，UIImageRenderingMode已重命名为UIImage.RenderingMode 

extension UIButton {
    func leftImage(image: UIImage, renderMode: UIImage.RenderingMode) {
        self.setImage(image.withRenderingMode(renderMode), for: .normal)
        self.imageEdgeInsets = UIEdgeInsets(top: 0, left: 0, bottom: 0, right: image.size.width / 2)
        self.contentHorizontalAlignment = .left
        self.imageView?.contentMode = .scaleAspectFit
    }

    func rightImage(image: UIImage, renderMode: UIImage.RenderingMode){
        self.setImage(image.withRenderingMode(renderMode), for: .normal)
        self.imageEdgeInsets = UIEdgeInsets(top: 0, left:image.size.width / 2, bottom: 0, right: 0)
        self.contentHorizontalAlignment = .right
        self.imageView?.contentMode = .scaleAspectFit
    }
}

创建按钮并将文本对齐方式设置为居中，然后添加：

UIImage *image = [UIImage imageNamed:@"..."];
CGSize imageSize = image.size;
CGFloat offsetY = floor((self.layer.bounds.size.height - imageSize.height) / 2.0);

CALayer *imageLayer = [CALayer layer];
imageLayer.contents = (__bridge id) image.CGImage;
imageLayer.contentsGravity = kCAGravityBottom;
imageLayer.contentsScale = [UIScreen mainScreen].scale;
imageLayer.frame = CGRectMake(offsetY, offsetY, imageSize.width, imageSize.height);
[self.layer addSublayer:imageLayer];

正如我所想，对于任何文本而言，良好的解决方案必须是有用的，没有用于插入的硬编码值（它是关于toytoy提供的解决方案）。我使用类似的代码：

NSString *sometitle = @"blabla button title";
NSString *someimage = @"blablaimage";
UIImage *image = [[UIImage imageNamed:someimage];
int buttonWidth = A;
int buttonHeight = B;
int imageWidth =image.size.width;
int imageHeight = image.size.height;
int titleWidth = buttonWidth - imageWidth;

// create button and set image and title
buttonView = [[UIButton alloc] initWithFrame:CGRectMake(0, 0, buttonWidth, buttonHeight)];
[buttonView setImage:image forState:UIControlStateNormal];
[buttonView setTitle:sometitle forState:UIControlStateNormal];

// make button all content to be left aligned
[buttonView setContentHorizontalAlignment:UIControlContentHorizontalAlignmentLeft];

// set title font 
[buttonView.titleLabel setFont:[UIFont fontWithName:@"HelveticaNeue" size:14]];

// calculate font text width with selected font
CGSize stringBoundingBox = [number sizeWithFont:[buttonView.titleLabel font]];

// make title inset with some value from left 
// it place the title right on the center of space for the title
int titleLeft = (titleWidth - stringBoundingBox.width) / 2;
[buttonView setTitleEdgeInsets:UIEdgeInsetsMake(0, titleLeft, 0, 0)];

在使用stringBoundingBox init的字符串之后，我还添加了一些这样的字符串：

if (stringBoundingBox.width > titleWidth)
{
    [_backgroundView.titleLabel setFont:[UIFont fontWithName:@"HelveticaNeue" size:13]];
    stringBoundingBox = [number sizeWithFont:[_backgroundView.titleLabel font]];
}
if (stringBoundingBox.width > titleWidth)
{
    [_backgroundView.titleLabel setFont:[UIFont fontWithName:@"HelveticaNeue" size:12]];
    stringBoundingBox = [number sizeWithFont:[_backgroundView.titleLabel font]];
}

它允许我通过选择一些较小的字体来设置比可用空间更长的标题。我这样做是因为另一种方式：

[buttonView.titleLabel setAdjustsFontSizeToFitWidth:YES];

工作效果不是很好，看起来它的字体大小一步缩小了3-4个点，所以有些不那么长的线条变得太小了。

此代码允许我们将按钮标题空间中的任何文本正好放在中心。

        let margin = 30 - image.size.width / 2
        let titleRect = titleRectForContentRect(bounds)
        let titleOffset = (bounds.width - titleRect.width - image.size.width - margin) / 2


        contentHorizontalAlignment = UIControlContentHorizontalAlignment.Left
            imageEdgeInsets = UIEdgeInsetsMake(0, margin, 0, 0)
            titleEdgeInsets = UIEdgeInsetsMake(0, (bounds.width - titleRect.width -  image.size.width - margin) / 2, 0, 0)

        guard let imageViewWidth = self.imageView?.frame.width else{return}
        guard let titleLabelWidth = self.titleLabel?.intrinsicContentSize.width else{return}
        self.contentHorizontalAlignment = .left
        let imageLeft = imagePadding - imageViewWidth / 2
        let titleLeft = (bounds.width - titleLabelWidth) / 2 - imageViewWidth
        imageEdgeInsets = UIEdgeInsets(top: 0.0, left: imageLeft, bottom: 0.0, right: 0.0)

我的 SWIFT 5.2 解决方案。

您必须继承UIButton类。无需像其他答案中那样更改内容的水平对齐方式，只需将其保持在“中心”（.center）即可。标题将自动居中，而imageRect（）的覆盖将解决图像问题。

您要做的第一件事是在故事板的“身份检查器”部分中将CustomButton类分配给您的按钮。 然后，您可以在“属性检查器”部分将“ alignImageToLeft”切换为“开”或“关”（默认为“关”）。

class CustomButton : UIButton {

    @IBInspectable var alignImageToLeft : Bool = false

    override func imageRect(forContentRect contentRect: CGRect) -> CGRect {
        if(alignImageToLeft){
            let imageRect = super.imageRect(forContentRect: contentRect)
            let offset = contentRect.minX - imageRect.minX
            return imageRect.offsetBy(dx: offset, dy: 0.0)
        }
        return super.imageRect(forContentRect: contentRect)
    }
}

我知道这个答案有点晚了。 但是对于想要使用UIImageView在具有居中文本的UIButton的左侧添加图像的人来说，我有一个非常简单的解决方案。全部以编程方式

class RandomVC: UIViewController{

    var imageDemo: UIImageView = {
    let img = UIImageView()
    img.translatesAutoresizingMaskIntoConstraints = false
    img.image = UIImage(named: "someImgFromAssets")
    return img
    }()

    lazy var someButton: UIButton = { //lazy var: so button can have access to self class
    let button = UIButton(type: .system)
    button.setTitle("This is your title", for: UIControlState.normal)
    button.translatesAutoresizingMaskIntoConstraints = false 
    button.setTitleColor(UIColor.white, for: UIControlState.normal)
    button.addTarget(self, action: #selector(handleButtonClick), for: .touchUpInside) //make sure you write function "handleButtonClick" inside your class
    button.titleLabel?.textAlignment = .center
    return button
    }()

    override func viewDidLoad() {
        super.viewDidLoad()
        view.addSubView(someButton)
        someButton.addSubview(imageDemo)
        imageDemo.centerYAnchor.constraint(equalTo: someButton.centerYAnchor).isActive = true
        imageDemo.leftAnchor.constraint(equalTo: someButton.leftAnchor, constant: 10).isActive = true
        imageDemo.heightAnchor.constraint(equalToConstant: 25).isActive = true
        imageDemo.widthAnchor.constraint(equalToConstant: 25).isActive = true
    }

我在swift中写了一个UIButton扩展 - 

extension UIButton {

func setLeftImage(imageName:String, padding:CGFloat) {
        //Set left image
        let image = UIImage(named: imageName)
        self.setImage(image, forState: .Normal)

        //Calculate and set image inset to keep it left aligned
        let imageWidth = image?.size.width
        let textWidth = self.titleLabel?.intrinsicContentSize().width
        let buttonWidth = CGRectGetWidth(self.bounds)

        let padding:CGFloat = 30.0
        let rightInset = buttonWidth - imageWidth!  - textWidth! - padding

        self.imageEdgeInsets = UIEdgeInsets(top: 0, left: 0, bottom: 0, right: rightInset)
    }
}

我会以我想要的任何方式设置我的按钮文本样式，保持中心对齐。 然后我会在我的按钮上调用这个方法，如 - 

myButton.setLeftImage("image_name", 30.0)

这会导致我的图像与左边框的某些填充对齐。

我已经尝试了几乎所有上述解决方案，并且没有一个像我预期的那样工作（我有两个按钮，每个按钮具有不同的tittle和不同的图像宽度）。所以我为UIButton编写了自己的扩展，它可以完美地运行不同的图像宽度以及不同的标题。 

extension UIButton {
    func moveImageLeftTextCenter(imagePadding: CGFloat = 30.0){
        guard let imageViewWidth = self.imageView?.frame.width else{return}
        guard let titleLabelWidth = self.titleLabel?.intrinsicContentSize.width else{return}
        self.contentHorizontalAlignment = .left
        imageEdgeInsets = UIEdgeInsets(top: 0.0, left: imagePadding - imageViewWidth / 2, bottom: 0.0, right: 0.0)
        titleEdgeInsets = UIEdgeInsets(top: 0.0, left: (bounds.width - titleLabelWidth) / 2 - imageViewWidth, bottom: 0.0, right: 0.0)

您可能会忘记UIEdgeInsets，而只是在UIButton子类中的layoutSubviews（）中覆盖框架。

要使titleLable居中，只需将super.bounds.midX和titleLabel.frame.midX之间的差异添加到titleLabel框架的水平偏移量

   override func layoutSubviews() {
       super.layoutSubviews()
       
       if let label = titleLabel {
           label.frame = label.frame.offsetBy(dx: super.bounds.midX - 
                label.frame.midX , dy: 0)
       }

       // Available space to the left of the titleLabel is simply:
       let leftAvailableWidth = label.frame.minX

       imageView?.frame = CGRect(x: 0, y: 0, width: <Some width smaller than leftAvailableWidth>, height: super.bound.height)

        self.titleLabel?.isHidden = true

        imageV.frame = CGRect(x: 0, y: 0, width: 40, height: self.bounds.height)
        imageV.contentMode = .scaleAspectFit

        titleV.frame = CGRect(x: 40, y: 0, width: self.bounds.width - 40, height: self.bounds.height)
        titleV.font = self.titleLabel?.font
        titleV.textAlignment = .center

        self.addSubview(imageV)
        self.addSubview(titleV)

        imageV.image = self.imageView?.image; titleV.text = self.titleLabel?.text

        imageV.translatesAutoresizingMaskIntoConstraints = false
        imageV.topAnchor.constraint(equalTo: self.topAnchor, constant: 0).isActive = true
        imageV.bottomAnchor.constraint(equalTo: self.bottomAnchor, constant: 0).isActive = true
        imageV.leadingAnchor.constraint(equalTo: self.leadingAnchor, constant: 0).isActive = true
        imageV.trailingAnchor.constraint(equalTo: titleV.leadingAnchor, constant: 0).isActive = true
        imageV.widthAnchor.constraint(equalToConstant: 40).isActive = true

        titleV.translatesAutoresizingMaskIntoConstraints = false
        titleV.topAnchor.constraint(equalTo: self.topAnchor).isActive = true
        titleV.bottomAnchor.constraint(equalTo: self.bottomAnchor).isActive = true
        titleV.trailingAnchor.constraint(equalTo: self.trailingAnchor, constant: 0).isActive = true
    }
}

然后您可以像这样设置图像和文本。

button.imageV.image = myImage
button.titleV.text = myText
