[ios] How to embed small icon in UILabel

I need to embed small icons ( sort of custom bullets ) to my UILabel in iOS7. How can I do this in interface designer? Or at least in code?

In Android there are leftDrawable and rightDrawable for labels, but how it is done in iOS? Sample in android :

This question is related to ios objective-c cocoa-touch ios7 textkit

The answer is


In Swift 5, By using UILabel extensions to embed icon in leading as well as trailing side of the text as follows:-

extension UILabel {
    
    func addTrailing(image: UIImage, text:String) {
        let attachment = NSTextAttachment()
        attachment.image = image

        let attachmentString = NSAttributedString(attachment: attachment)
        let string = NSMutableAttributedString(string: text, attributes: [:])

        string.append(attachmentString)
        self.attributedText = string
    }
    
    func addLeading(image: UIImage, text:String) {
        let attachment = NSTextAttachment()
        attachment.image = image

        let attachmentString = NSAttributedString(attachment: attachment)
        let mutableAttributedString = NSMutableAttributedString()
        mutableAttributedString.append(attachmentString)
        
        let string = NSMutableAttributedString(string: text, attributes: [:])
        mutableAttributedString.append(string)
        self.attributedText = mutableAttributedString
    }
}

To use above mentioned code in your desired label as:-

Image in right of text then:-

statusLabel.addTrailing(image: UIImage(named: "rightTick") ?? UIImage(), text: " Verified ")

Image in left of text then:-

statusLabel.addLeading(image: UIImage(named: "rightTick") ?? UIImage(), text: " Verified ")

Output:-

In Swift 2.0,

My solution to the problem is a combination of a couple of answers on this question. The problem I faced in @Phil's answer was that I couldn't change the position of the icon, and it always appeared in right the corner. And the one answer from @anatoliy_v, I couldn't resize the icon size I want to append to the string.

To make it work for me, I first did a pod 'SMIconLabel' and then created this function:

func drawTextWithIcon(labelName: SMIconLabel, imageName: String, labelText: String!,  width: Int, height: Int) {

        let newSize = CGSize(width: width, height: height)
        let image = UIImage(named: imageName)
        UIGraphicsBeginImageContextWithOptions(newSize, false, 0.0)
        image?.drawInRect(CGRectMake(0, 0, newSize.width, newSize.height))
        let imageResized = UIGraphicsGetImageFromCurrentImageContext()
        UIGraphicsEndImageContext()

        labelName.text = " \(labelText)"
        labelName.icon = imageResized
        labelName.iconPosition = .Left
    }

This solution will not only help you place the image but will also allow you to make necessary changes to the icon size and other attributes.

Thank You.


 func atributedLabel(str: String, img: UIImage)->NSMutableAttributedString
{   let iconsSize = CGRect(x: 0, y: -2, width: 16, height: 16)
    let attributedString = NSMutableAttributedString()
    let attachment = NSTextAttachment()
    attachment.image = img
    attachment.bounds = iconsSize
    attributedString.append(NSAttributedString(attachment: attachment))
    attributedString.append(NSAttributedString(string: str))

    return attributedString
} 

You can use this function to add images or small icons to the label


Swift 4.2:

let attachment = NSTextAttachment()        
attachment.image = UIImage(named: "yourIcon.png")
let attachmentString = NSAttributedString(attachment: attachment)
let myString = NSMutableAttributedString(string: price)
myString.append(attachmentString)
label.attributedText = myString

Swift 3 version

let attachment = NSTextAttachment()
attachment.image = UIImage(named: "plus")
attachment.bounds = CGRect(x: 0, y: 0, width: 10, height: 10)
let attachmentStr = NSAttributedString(attachment: attachment)
let myString = NSMutableAttributedString(string: "")
myString.append(attachmentStr)
let myString1 = NSMutableAttributedString(string: "My label text")
myString.append(myString1)
lbl.attributedText = myString

UILabel Extension

extension UILabel {

    func set(text:String, leftIcon: UIImage? = nil, rightIcon: UIImage? = nil) {

        let leftAttachment = NSTextAttachment()
        leftAttachment.image = leftIcon
        leftAttachment.bounds = CGRect(x: 0, y: -2.5, width: 20, height: 20)
        if let leftIcon = leftIcon {
            leftAttachment.bounds = CGRect(x: 0, y: -2.5, width: leftIcon.size.width, height: leftIcon.size.height)
        }
        let leftAttachmentStr = NSAttributedString(attachment: leftAttachment)

        let myString = NSMutableAttributedString(string: "")

        let rightAttachment = NSTextAttachment()
        rightAttachment.image = rightIcon
        rightAttachment.bounds = CGRect(x: 0, y: -5, width: 20, height: 20)
        let rightAttachmentStr = NSAttributedString(attachment: rightAttachment)


        if semanticContentAttribute == .forceRightToLeft {
            if rightIcon != nil {
                myString.append(rightAttachmentStr)
                myString.append(NSAttributedString(string: " "))
            }
            myString.append(NSAttributedString(string: text))
            if leftIcon != nil {
                myString.append(NSAttributedString(string: " "))
                myString.append(leftAttachmentStr)
            }
        } else {
            if leftIcon != nil {
                myString.append(leftAttachmentStr)
                myString.append(NSAttributedString(string: " "))
            }
            myString.append(NSAttributedString(string: text))
            if rightIcon != nil {
                myString.append(NSAttributedString(string: " "))
                myString.append(rightAttachmentStr)
            }
        }
        attributedText = myString
    }
}

try this way...

  self.lbl.text=@"Drawble Left";
    UIImageView *img=[[UIImageView alloc]initWithFrame:CGRectMake(0, 0, 20, 20)];
    img.image=[UIImage imageNamed:@"Star.png"];
    [self.lbl addSubview:img];

you have to make a custom object where you used a UIView and inside you put a UIImageView and a UILabel


Swift 2.0 version:

//Get image and set it's size
let image = UIImage(named: "imageNameWithHeart")
let newSize = CGSize(width: 10, height: 10)

//Resize image
UIGraphicsBeginImageContextWithOptions(newSize, false, 0.0)
image?.drawInRect(CGRectMake(0, 0, newSize.width, newSize.height))
let imageResized = UIGraphicsGetImageFromCurrentImageContext()
UIGraphicsEndImageContext()

//Create attachment text with image
var attachment = NSTextAttachment()
attachment.image = imageResized
var attachmentString = NSAttributedString(attachment: attachment)
var myString = NSMutableAttributedString(string: "I love swift ")
myString.appendAttributedString(attachmentString)
myLabel.attributedText = myString

Swift 5 Easy Way Just CopyPaste and change what you want

let fullString = NSMutableAttributedString(string:"To start messaging contacts who have Talklo, tap ")

 // create our NSTextAttachment
let image1Attachment = NSTextAttachment() 
image1Attachment.image = UIImage(named: "chatEmoji")
image1Attachment.bounds = CGRect(x: 0, y: -8, width: 25, height: 25)

// wrap the attachment in its own attributed string so we can append it
let image1String = NSAttributedString(attachment: image1Attachment)

 // add the NSTextAttachment wrapper to our full string, then add some more text.

 fullString.append(image1String)
 fullString.append(NSAttributedString(string:" at the right bottom of your screen"))

 // draw the result in a label
 self.lblsearching.attributedText = fullString

Your reference image looks like a button. Try (can also be done in Interface Builder):

enter image description here

UIButton* button = [UIButton buttonWithType:UIButtonTypeCustom];
[button setFrame:CGRectMake(50, 50, 100, 44)];
[button setImage:[UIImage imageNamed:@"img"] forState:UIControlStateNormal];
[button setImageEdgeInsets:UIEdgeInsetsMake(0, -30, 0, 0)];
[button setTitle:@"Abc" forState:UIControlStateNormal];
[button setTitleColor:[UIColor blackColor] forState:UIControlStateNormal];
[button setBackgroundColor:[UIColor yellowColor]];
[view addSubview:button];

You could use a UITextField with the leftView property and then set the enabled property to NO

Or use a UIButton and setImage:forControlState


Here is the way to embed icon in UILabel.

Also to Align the Icon use attachment.bounds


Swift 5.1

// Create Attachment
let imageAttachment = NSTextAttachment()
imageAttachment.image = UIImage(named:"iPhoneIcon")
// Set bound to reposition
let imageOffsetY: CGFloat = -5.0
imageAttachment.bounds = CGRect(x: 0, y: imageOffsetY, width: imageAttachment.image!.size.width, height: imageAttachment.image!.size.height)
// Create string with attachment
let attachmentString = NSAttributedString(attachment: imageAttachment)
// Initialize mutable string
let completeText = NSMutableAttributedString(string: "")
// Add image to mutable string
completeText.append(attachmentString)
// Add your text to mutable string
let textAfterIcon = NSAttributedString(string: "Using attachment.bounds!")
completeText.append(textAfterIcon)
self.mobileLabel.textAlignment = .center
self.mobileLabel.attributedText = completeText

Objective-C Version

NSTextAttachment *imageAttachment = [[NSTextAttachment alloc] init];
imageAttachment.image = [UIImage imageNamed:@"iPhoneIcon"];
CGFloat imageOffsetY = -5.0;
imageAttachment.bounds = CGRectMake(0, imageOffsetY, imageAttachment.image.size.width, imageAttachment.image.size.height);
NSAttributedString *attachmentString = [NSAttributedString attributedStringWithAttachment:imageAttachment];
NSMutableAttributedString *completeText = [[NSMutableAttributedString alloc] initWithString:@""];
[completeText appendAttributedString:attachmentString];
NSAttributedString *textAfterIcon = [[NSAttributedString alloc] initWithString:@"Using attachment.bounds!"];
[completeText appendAttributedString:textAfterIcon];
self.mobileLabel.textAlignment = NSTextAlignmentRight;
self.mobileLabel.attributedText = completeText;

Swift 4 UIlabel Extension to add Image to Label with reference to above answers

extension UILabel {
  func set(image: UIImage, with text: String) {
    let attachment = NSTextAttachment()
    attachment.image = image
    attachment.bounds = CGRect(x: 0, y: 0, width: 10, height: 10)
    let attachmentStr = NSAttributedString(attachment: attachment)

    let mutableAttributedString = NSMutableAttributedString()
    mutableAttributedString.append(attachmentStr)

    let textString = NSAttributedString(string: text, attributes: [.font: self.font])
    mutableAttributedString.append(textString)

    self.attributedText = mutableAttributedString
  }
}

Swift 3 UILabel extention

Tip: If you need some space between the image and the text just use a space or two before the labelText.

extension UILabel {
    func addIconToLabel(imageName: String, labelText: String, bounds_x: Double, bounds_y: Double, boundsWidth: Double, boundsHeight: Double) {
        let attachment = NSTextAttachment()
        attachment.image = UIImage(named: imageName)
        attachment.bounds = CGRect(x: bounds_x, y: bounds_y, width: boundsWidth, height: boundsHeight)
        let attachmentStr = NSAttributedString(attachment: attachment)
        let string = NSMutableAttributedString(string: "")
        string.append(attachmentStr)
        let string2 = NSMutableAttributedString(string: labelText)
        string.append(string2)
        self.attributedText = string
    }
}

Try dragging a UIView onto the screen in IB. From there you can drag a UIImageView and UILabel into the view you just created. Set the image of the UIImageView in the properties inspector as the custom bullet image (which you will have to add to your project by dragging it into the navigation pane) and you can write some text in the label.


I've made an implementation of this feature in swift here: https://github.com/anatoliyv/SMIconLabel

Code is as simple as it's possible:

var labelLeft = SMIconLabel(frame: CGRectMake(10, 10, view.frame.size.width - 20, 20))
labelLeft.text = "Icon on the left, text on the left"

// Here is the magic
labelLeft.icon = UIImage(named: "Bell") // Set icon image
labelLeft.iconPadding = 5               // Set padding between icon and label
labelLeft.numberOfLines = 0             // Required
labelLeft.iconPosition = SMIconLabelPosition.Left // Icon position
view.addSubview(labelLeft)

Here is how it looks:

SMIconLabel image
