Showing Uilabel's Text

UILabel don't show all text

Just follow the code below.

// Swift
textLabel.lineBreakMode = .ByWordWrapping // or NSLineBreakMode.ByWordWrapping
textLabel.numberOfLines = 0 

// For Swift >= 3
textLabel.lineBreakMode = .byWordWrapping // notice the 'b' instead of 'B'
textLabel.numberOfLines = 0

// Objective-C
textLabel.lineBreakMode = NSLineBreakByWordWrapping;
textLabel.numberOfLines = 0;

// C# (Xamarin.iOS)
textLabel.LineBreakMode = UILineBreakMode.WordWrap;
textLabel.Lines = 0;  

Can not show my text in UILabel

This is a thread issue. URLSession is is asynchronous, so you have to update the UI in the completionHandler.

let task = URLSession.shared.dataTask(with: url as URL, completionHandler: { (data, response, error) -> Void in
    //print(data)

    if let pocetDatabaze = NSString(data: data!, encoding: String.Encoding.ascii.rawValue) {

        self.pocetDatabaze2 = Int(pocetDatabaze as String)!
        self.pocetDatabaze3 = String(pocetDatabaze2 as Int)
        DispatchQueue.main.async {
            self.aktualniPocet.text = pocetDatabaze3
        }
    }

})

You need a call to DispatchQueue.main because you should update the UI in the main thread. Then you can comment out the other two calls.

Swift: UILabel how to show all text

you can do this by setting numberOfLines to 0

Example

 myLabel.text = "whatever"
 myLabel.numberOfLines = 0
 myLabel.lineBreakMode = NSLineBreakMode.ByWordWrapping

And you have so set frame according to it

Custom UILabel is not displaying text

To debug, I created a new single view app and added MyLabel.h and MyLabel.m files to project.

I Used Xcode 8 and iPhone 5S simulator.

But the result were same no text was being displayed by MyLabel.

Frustrated me, removed all the code from MyLabel.h and MyLabel.m except properties in MyLabel.h, overall class looked like below:

Header File:

#import <UIKit/UIKit.h>

IB_DESIGNABLE

@interface MyLabel : UILabel

@property (nonatomic) IBInspectable CGFloat letterSpacing;
@property (nonatomic) IBInspectable CGFloat lineSpacing;

@end

Implementation File:

#import "MyLabel.h"

@implementation MyLabel

@end

Even with above code, no text was displayed by MyLabel.

Now I decided to rename the properties like below:

@property (nonatomic) IBInspectable CGFloat ltrSpacing;
@property (nonatomic) IBInspectable CGFloat lnSpacing;

Surprisingly MyLabel started displaying the text, weird.

Then I re-introduced my logic and everything is working fine.

I think the property names I chose were conflicting with some of UILabel's private properties but I am not sure about the exact reason.

A bit difficult to know for certain, because you didn't provide a complete working example, but this may fix your issue.

UILabel custom Text

You can use NSTextAttachment for that behaviour. I modify this for position of attachment.

All code :

  @IBOutlet weak var lbl: UILabel!

override func viewDidLoad() {
    super.viewDidLoad()
   
    let string = "Urban points users average montly saving is "

    
    let normalNameString = NSMutableAttributedString.init(string: string)

    let attachment = NSTextAttachment()
    attachment.image = imageHelper.pgImage(textValue: "QAR 115 ", lbl: lbl)
    
    attachment.bounds = CGRect(x: 0, y: (lbl.font.capHeight - attachment.image!.size.height).rounded() / 2, width: attachment.image!.size.width, height: attachment.image!.size.height)

    
    normalNameString.append(NSAttributedString(attachment: attachment))
    normalNameString.append(NSAttributedString(string: "You have saved "))
    
    let attachment2 = NSTextAttachment()
    attachment2.image = imageHelper.pgImage(textValue: "QAR 29",textColor: UIColor.yellow,backgroundColor: UIColor.black , lbl: lbl)
    attachment2.bounds = CGRect(x: 0, y: (lbl.font.capHeight - attachment2.image!.size.height).rounded() / 2, width: attachment2.image!.size.width, height: attachment2.image!.size.height)
   
    normalNameString.append(NSAttributedString(attachment: attachment2))
    normalNameString.append(NSAttributedString(string: " this month"))

    lbl.attributedText = normalNameString
}

}

class imageHelper{
static func pgImage(textValue:String,textColor : UIColor = UIColor.white , backgroundColor : UIColor = UIColor.red,lbl : UILabel) ->UIImage{
    let label = UILabel(frame: CGRect(x: 0, y: 0, width: (textValue as NSString).size(withAttributes: [NSAttributedString.Key.font : lbl.font!]).width, height: lbl.frame.size.height))
    label.font = lbl.font
    label.textAlignment = .center
    label.textColor = textColor
    label.backgroundColor = backgroundColor
    label.layer.borderColor = UIColor.darkGray.cgColor
    label.layer.borderWidth = 1
    label.layer.cornerRadius = label.frame.size.height/2
    label.layer.masksToBounds = true
    label.text = textValue
    label.numberOfLines = 1

    UIGraphicsBeginImageContextWithOptions(label.bounds.size, false,UIScreen.main.scale)
    label.layer.render(in: UIGraphicsGetCurrentContext()!)

    let image = UIGraphicsGetImageFromCurrentImageContext()
    UIGraphicsEndImageContext()
    return image!
}
}

And the result is :
