I use this code so that when I click on button 1, button 2 is hidden
#IBOutlet weak var button2: UIButton!
#IBOutlet weak var button1: UIButton!
#IBAction func button1(_ sender: Any) {
button2.isHidden = false
}
How can I make it so that when you press button 1 again, button 2 is displayed.
You can simply use this tricks:
#IBAction func button1(_ sender: UIButton) {
button2.isHidden = !button2.isHidden
}

I have 2 UISwitch and a Button, in viewDidLoad, I set the button to be hidden and disabled, I want only my button to be not hidden if those 2 switch is in ON state, otherwise, I want my button to hide again. is there any method from UI Switch delegate that can be used ? how do I do that in Swift ?
here is the code I use
import UIKit
class AskingAuthorizationVC: UIViewController {
#IBOutlet weak var locationSwitch: DesignableSwitch!
#IBOutlet weak var notificationSwitch: DesignableSwitch!
#IBOutlet weak var nextButton: DesignableButton!
override func viewDidLoad() {
super.viewDidLoad()
// initial state
nextButton.isHidden = true
nextButton.isEnabled = false
notificationSwitch.isOn = false
locationSwitch.isOn = false
}
#IBAction func signUpButtonDidPressed(_ sender: Any) {
performSegue(withIdentifier: "toAuthenticationVC", sender: nil)
}
}
Hook both of the UISwitch-s as IBActions & IBOutlets
#IBAction func oweSwitch(_ sender: UISwitch) {
self.mybutton.isHidden = !(switch1.isOn && switch2.isOn)
}
Right now i have a purple and red score. I would like to use the 1 and 2 buttons to add the score for the colors. I know how to do this by creating just a sets of buttons to the specific color but doing this again and again will create problems. So what I am trying to do is if purple is selected and if and only if 1 is pressed then the total score of purple will = 1. I guess what I am trying is perform a switch statement for the buttons.
Before purple/red button is pressed.
After purple/red button is pressed.
import UIKit
class ViewController: UIViewController {
var purpleScore = 0
var redScore = 0
#IBOutlet var plus1: UIButton!
#IBOutlet var plus2: UIButton!
#IBOutlet var addRed: UIButton!
#IBOutlet var addPurlple: UIButton!
#IBOutlet var totalScorePurple: UILabel!
#IBOutlet var totalScoreRed: UILabel!
override func viewDidLoad() {
super.viewDidLoad()
plus1.isHidden = true
plus2.isHidden = true
}
#IBAction func enteringRed(_ sender: Any) {
plus1.isHidden = false
plus2.isHidden = false
}
#IBAction func enteringPurple(_ sender: Any) {
plus1.isHidden = false
plus2.isHidden = false
}
#IBAction func plus1(_ sender: Any) {
}
#IBAction func plus2(_ sender: Any) {
}
}
If I understand correctly as the comment above, this should work
Create 2 Bool for red and purple to see weather they are checked or not, this is easiest way, else you can just check the redButton color got changed (if it does) or .selected = true
var redChecked = false
var purpleChecked = false
#IBAction func enteringRed(_ sender: Any) {
redChecked = !redChecked
//change color etc..
}
#IBAction func enteringPurple(_ sender: Any) {
purpleChecked = !purpleChecked
//change color etc..
}
#IBAction func plus1(_ sender: Any) {
if redChecked {
redScore+=1
}
if purpleChecked {
purpleScore+=1
}
}
#IBAction func plus2(_ sender: Any) {
if redChecked {
redScore+=2
}
if purpleChecked {
purpleScore+=2
}
}
For the radioButtons I have used Class in the button and for the indicator to buttons i have used the labels.
These are My TextView
#IBOutlet weak var TextViewEveryNewMessage: UILabel!
#IBOutlet weak var TextViewWeekly: UILabel!
#IBOutlet weak var TextViewDaily: UILabel!
#IBOutlet weak var TextViewMonthly: UILabel!
These are my Radio Buttons
#IBOutlet weak var RadioBtnMonthly: SSRadioButton!
#IBOutlet weak var RadioBtnWeekly: SSRadioButton!
#IBOutlet weak var RadioBtnDefaultChecked: SSRadioButton!
#IBOutlet weak var RadioBtnDaily: SSRadioButton!
As soon as i press the ok button i need to save the checkedRadio Button text somewhere and i have done it like this.
#IBAction func OkButton(sender: UIButton) {
SwiftSpinner.show(kLoadingText)
if RadioBtnDefaultChecked.selected{
preferencesConditions.notificationFrequency = self.TextViewEveryNewMessage.text
}else if RadioBtnDaily.selected{
preferencesConditions.notificationFrequency = self.TextViewDaily.text
}else if RadioBtnWeekly.selected{
preferencesConditions.notificationFrequency =
self.TextViewWeekly.text
}else{
preferencesConditions.notificationFrequency = self.TextViewMonthly.text
}
Is this correct way i am doing.Or there are any other approach. Please suggest me.
Instead of assigning a value for preferencesConditions.notificationFrequency in OkButton(sender: UIButton), you should do it in each of the SSRadioButton buttons and that's by calling SSRadioButtonControllerDelegate - didSelectButton:
func didSelectButton(aButton: UIButton?) {
print(aButton)
if aButton === RadioBtnDefaultChecked {
preferencesConditions.notificationFrequency = self.TextViewEveryNewMessage.text
}else if aButton === RadioBtnDaily {
preferencesConditions.notificationFrequency = self.TextViewDaily.text
}else if aButton === RadioBtnWeekly {
preferencesConditions.notificationFrequency =
self.TextViewWeekly.text
}else{
preferencesConditions.notificationFrequency = self.TextViewMonthly.text
}
}
Don't forget to conform the delegate to the viewController:
var radioButtonController: SSRadioButtonsController?
override func viewDidLoad() {
radioButtonController = SSRadioButtonsController(buttons: RadioBtnDefaultChecked, RadioBtnDaily, RadioBtnWeekly)
radioButtonController!.delegate = self
radioButtonController!.shouldLetDeSelect = true
}
The IBAction should be like:
#IBAction func OkButton(sender: UIButton) {
SwiftSpinner.show(kLoadingText)
}
For more information, check SSRadioButtonsController.
Hope this helped.
So I'm pretty new but I'm trying to reference a button from another. I disable the first button when I press it, but I want to enable it when I press the other button. Check this out. It doesn't like my second sender reference.
#IBAction func IBbtnUpdateTap(sender: UIButton){
sender.enabled = false
}
#IBAction func addSpinsButton() {
sender.enabled = true
}
Any ideas from you coding wizards?
The problem is that the context of your function addSpinsButton as no sender variable. You must add a reference to your button in the class.
You can do this with something like:
#IBOutlet weak var myButton: UIButton!
Link the button in interface builder (same way you have done with your function, but for the outlet)
Then your addSpinsButton will become:
#IBAction func addSpinsButton() {
myButton.enabled = true
}
what you need is something like this:
class ViewController: UIViewController {
#IBOutlet weak var button1: UIButton!
#IBOutlet weak var button2: UIButton!
#IBAction func button1Tapped(sender: UIButton) {
sender.enabled = false
}
#IBAction func button2Tapped(sender: UIButton) {
button1.enabled = true
}
}
