This time I tried to make UILabel part of a bold text,  using func so that many other UILabels can be used.





import UIKit

class MentionHalfBoldViewController: UIViewController {
    @IBOutlet weak var labelBold: UILabel!
    
    override func viewDidLoad() {
        super.viewDidLoad()
        
        labelBold.attributedText = attributedTextWith(withString: String(format: "Name : %@", "Jonny"), boldString: "Name", font: labelBold.font)
    }
    
    func attributedTextWith(withString string: String, boldString: String, font: UIFont) -> NSAttributedString {
        let attributedString = NSMutableAttributedString(string: string,
                                                         attributes: [NSAttributedStringKey.font: font])
        let boldFontAttribute: [NSAttributedStringKey: Any] = [NSAttributedStringKey.font: UIFont.boldSystemFont(ofSize: font.pointSize)]
        let range = (string as NSString).range(of: boldString)
        attributedString.addAttributes(boldFontAttribute, range: range)
        return attributedString
    }
}

You can use Cocoapod or Carthage, for install cek link github Localize, this time I try localize use xib file. let's start.

1. Create new file ".xib" and ".swift" file
2. Intall library Localize
3.  In xib file use label and button,  in view you can give 4 label and 1 button like image below.



4.  Follow or copy this code. in full file

- LocalizeViewController.swift

import UIKit
import Localize

class MenuViewController: UIViewController {

    override func viewDidLoad() {
        super.viewDidLoad()

     
    }
    @IBAction func bAction(_ sender: Any) {
        let alert = UIAlertController(title: nil, message: nil, preferredStyle: .actionSheet)
        alert.addAction(UIAlertAction(title: "English", style: .default, handler: { _ in
            Localize.update(language: "en")
        }))
        alert.addAction(UIAlertAction(title: "Indonesia", style: .default, handler: { _ in
            Localize.update(language: "id")
        }))
        alert.addAction(UIAlertAction(title: "Cancel", style: .cancel, handler: nil))
        present(alert, animated: true, completion: nil)
    }
}


- AppDelegate.swift

import UIKit
import Localize

@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {

var window: UIWindow?


func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
// Override point for customization after application launch.

let localize = Localize.shared
// Set your localize provider.
localize.update(provider: .json)
// Set your file name
localize.update(fileName: "lang")
// Set your default languaje.
localize.update(defaultLanguage: "id")
// If you want change a user language, different to default in phone use thimethod.
localize.update(language: "en")
// If you want remove storaged languaje use
localize.resetLanguage()
// The used language
print(localize.currentLanguage)
// List of aviable languajes
print(localize.availableLanguages)

// Or you can use static methods for all
Localize.update(fileName: "lang")
Localize.update(defaultLanguage: "id")
Localize.update(language: "en-DE")
        
        window = UIWindow(frame: UIScreen.main.bounds)
        window?.makeKeyAndVisible()
        window?.rootViewController = UINavigationController(rootViewController: MenuViewController())

return true
}

func applicationWillResignActive(_ application: UIApplication) {}
func applicationDidEnterBackground(_ application: UIApplication) {}
func applicationWillEnterForeground(_ application: UIApplication) {}
func applicationDidBecomeActive(_ application: UIApplication) {}
func applicationWillTerminate(_ application: UIApplication) {}

I have problem "how to setting spotlight mac can't find all application in mac" that key word i search in google, in my mac can't find apps in spotlight search




First solution from apple follow this step

1. Choose Apple menu () > System Preferences, then click Spotlight.
2. Click the Privacy tab.
3. Drag the folder or disk that you want to index again to the list of locations that Spotlight is prevented from searching. Or click the Add (+) button and select the folder or disk to add.
   To add an item to the Privacy tab, you must have ownership permissions for that item. To learn about permissions, choose Help from the Finder menu bar, then search for “permissions.”
4. From the same list of locations, select the folder or disk that you just added. Then click the Remove (–) button to remove it from the list.
5. Quit System Preferences. Spotlight will reindex the contents of the folder or disk.

I have a problem if using UITabBarController, center button icon in hold touch an swipe icon make size small, If you have the same problem you can solve like this below



import UIKit

class TabbarViewController: UITabBarController {

    override func viewDidLoad() {
        super.viewDidLoad()
        self.tabBar.backgroundImage = UIImage()
        self.tabBar.backgroundColor = #colorLiteral(red: 1.0, green: 1.0, blue: 1.0, alpha: 1.0)
        self.view.backgroundColor = #colorLiteral(red: 1, green: 1, blue: 1, alpha: 1)
   
        let leftVC = UIViewController()
        let centerVC = ForTestPart5VC()
        let rightVC = UIViewController()
       
        leftVC.tabBarItem = UITabBarItem(title: "Left", image: UIImage(named: "e1.png"), tag: 0)
        centerVC.tabBarItem = UITabBarItem(title: "Center", image: UIImage(named: "e2.png"), tag: 1)
        rightVC.tabBarItem = UITabBarItem(title: "Right", image: UIImage(named: "e3.png"), tag: 2)
       
        centerVC.tabBarItem.imageInsets = UIEdgeInsetsMake(7, 0, -6, 0) // Error in here
        viewControllers = [leftVC, centerVC, rightVC]
    }

}

Solution: In UIEdgeInsetsMake top and bottom must be same number setting.

centerVC.tabBarItem.imageInsets = UIEdgeInsetsMake(7, 0, -7, 0) // fix
