How to Show Hint View In Swift

Hello guys, Today we learn about How to Show Hint View In Swift.

Sometimes, we need to add a hint view for user preference where the user can get the exact meaning of your point. for example, if I am using a text field like password and I want to give any instruction regarding the password field for the user then I can use hint view. The hint view is like a pop-up view.

Getting Started:-

Step1:- Firstly, Create an XCode project.

File–> New–> Project–> iOS–> Next And add your project name then create.

Step 2:- Secondly, Create a UI design for the view in the stoaryboard.

Step 4:- For hint view, we need to install cocoa pods into our project

pod "AMPopTip"

1	pod "AMPopTip"

How to install the pod file-

open terminal
write pod init
Then open profile
add pod “pod “AMPopTip”
And, run the pod install command
open .xcworkspace project

Step 5:- To call the pop-Tip function we will create a class and add the code

import UIKit
import AMPopTip
struct popupInfoMessageView{
    static  let popTipView = PopTip()
    static func show(sender:UIButton,message:String,view:UIView){
        popTip.shouldDismissOnTap = true
        popTip.shouldDismissOnTapOutside = true
        popTip.shouldDismissOnSwipeOutside = true
        popTip.bubbleColor = .black
        popTip.show(text: message, direction: .down, maxWidth: SCREEN_WIDTH-16, in: view, from: sender.frame)
    }
}

import UIKit

import AMPopTip

struct popupInfoMessageView{

static let popTipView = PopTip()

static func show(sender:UIButton,message:String,view:UIView){

popTip.shouldDismissOnTap = true

popTip.shouldDismissOnTapOutside = true

popTip.shouldDismissOnSwipeOutside = true

popTip.bubbleColor = .black

popTip.show(text: message, direction: .down, maxWidth: SCREEN_WIDTH-16, in: view, from: sender.frame)

}

Step 6:- Lastly, Add the code in your view controller class and run the project.

import UIKit
import AMPopTip
let SCREEN_WIDTH = ((UIApplication.shared.statusBarOrientation == .portrait) || (UIApplication.shared.statusBarOrientation == .portraitUpsideDown) ? UIScreen.main.bounds.size.width : UIScreen.main.bounds.size.height)
class ViewController: UIViewController {

    @IBOutlet weak var passwordHint: UIButton!
    @IBOutlet weak var nameHint: UIButton!
    @IBOutlet weak var passwordLabel: UITextField!
    @IBOutlet weak var nameLabel: UITextField!
    
    var isNameHint:Bool = false
    var isPasswordHint:Bool = false
    
    
    override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view.
    }

    @IBAction func nameHintClick(_ sender: UIButton) {
      
        isNameHint = !isNameHint
        if isNameHint{
        popupInfoMessageView.popTipView.removeFromSuperview()
        popupInfoMessageView.show(sender:sender,message:"Enter your FirstName and LastName",view:view)
        }else{
            popupInfoMessageView.popTipView.hide()
        }
    }
    @IBAction func passwordHintClick(_ sender: UIButton) {
   
        isPasswordHint = !isPasswordHint
        if isPasswordHint{
        popupInfoMessageView.popTipView.removeFromSuperview()
        popupInfoMessageView.show(sender:sender,message:"Enter your Password, it should be contain capital and small letter and number's ",view:view)
        }else{
            popupInfoMessageView.popTipView.hide()
        }

    }
    
}

import UIKit

import AMPopTip

let SCREEN_WIDTH = ((UIApplication.shared.statusBarOrientation == .portrait) || (UIApplication.shared.statusBarOrientation == .portraitUpsideDown) ? UIScreen.main.bounds.size.width : UIScreen.main.bounds.size.height)

class ViewController: UIViewController {

@IBOutlet weak var passwordHint: UIButton!

@IBOutlet weak var nameHint: UIButton!

@IBOutlet weak var passwordLabel: UITextField!

@IBOutlet weak var nameLabel: UITextField!

var isNameHint:Bool = false

var isPasswordHint:Bool = false

override func viewDidLoad() {

super.viewDidLoad()

// Do any additional setup after loading the view.

}

@IBAction func nameHintClick(_ sender: UIButton) {

isNameHint = !isNameHint

if isNameHint{

popupInfoMessageView.popTipView.removeFromSuperview()

popupInfoMessageView.show(sender:sender,message:"Enter your FirstName and LastName",view:view)

}else{

popupInfoMessageView.popTipView.hide()

}

@IBAction func passwordHintClick(_ sender: UIButton) {

isPasswordHint = !isPasswordHint

if isPasswordHint{

popupInfoMessageView.popTipView.removeFromSuperview()

popupInfoMessageView.show(sender:sender,message:"Enter your Password, it should be contain capital and small letter and number's ",view:view)

}else{

popupInfoMessageView.popTipView.hide()

}

And the output is-
