UILabel에 작은 아이콘을 포함시키는 방법

UILabel에 작은 아이콘을 포함시키는 방법

UILabeliOS7에서 작은 아이콘 (맞춤형 글 머리 기호)을 포함시켜야합니다 . 인터페이스 디자이너에서 어떻게해야합니까? 아니면 적어도 코드에서?

안드로이드에있다 leftDrawable및 rightDrawable라벨 있지만 아이폰 OS에서 수행하는 방법? 안드로이드 샘플 :

---

TextKit의 일부인 iOS 7의 텍스트 첨부 파일 로이를 수행 할 수 있습니다 . 일부 샘플 코드 :

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;

UILabel에 아이콘을 포함시키는 방법은 다음과 같습니다.

또한 아이콘 을 정렬 하려면 attachment.bounds를 사용 하십시오.

스위프트 4.2

//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 = NSMutableAttributedString(string: "Using attachment.bounds!")
completeText.append(textAfterIcon)
self.mobileLabel.textAlignment = .center;
self.mobileLabel.attributedText = completeText;

오브젝티브 -C 버전

 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];
NSMutableAttributedString *textAfterIcon= [[NSMutableAttributedString alloc] initWithString:@"Using attachment.bounds!"];
[completeText appendAttributedString:textAfterIcon];
self.mobileLabel.textAlignment=NSTextAlignmentRight;
self.mobileLabel.attributedText=completeText;

스위프트 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

참조 이미지는 버튼처럼 보입니다. 시도하십시오 (인터페이스 빌더에서 수행 할 수도 있음).

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];

나는이 기능을 신속하게 구현했습니다 : 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:

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 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

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.

---

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

Or use a UIButton and setImage:forControlState

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.

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
    }
}

---

 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
