How to embed small icon in UILabel

Question

You can do this with iOS 7's text attachments, which are part of TextKit. Some sample code:

NSTextAttachment *attachment = [[NSTextAttachment alloc] init];
attachment.image = [UIImage imageNamed:@"MyIcon.png"];

NSAttributedString *attachmentString = [NSAttributedString attributedStringWithAttachment:attachment];

NSMutableAttributedString *myString= [[NSMutableAttributedString alloc] initWithString:@"My label text"];
[myString appendAttributedString:attachmentString];

myLabel.attributedText = myString;

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 4.2:

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
    }
}

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

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];
