When I run my application with the following code it only displays the first frame and doesn't loop through the other images.
class ViewController: UIViewController, UITextFieldDelegate {
var signUpMode = true
var activityIndicator = UIActivityIndicatorView()
#IBOutlet weak var emailText: UITextField!
#IBOutlet weak var passwordText: UITextField!
#IBOutlet weak var signIn: UIImageView!
//Animated sign in
var counter = 0
var animationStart = false
var timer = Timer()
func animateSignIn() {
signIn.image = UIImage(named: "frame_\(counter)_delay-0.04s.gif")
counter += 1
if counter == 128 {
counter = 0
}
}
func animation (){
if animationStart == true {
timer = Timer.scheduledTimer(timeInterval: 0.04, target: self, selector: #selector(ViewController.animateSignIn), userInfo: nil, repeats: true)
}
}
Then I set animationStart to true:
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
//remove root view controller navigation bar
self.navigationController?.navigationBar.isHidden = true
animationStart = true
}
Where did you call the function animation()?
I think viewDidLoad should look like this
override func viewDidLoad() {
super.viewDidLoad()
//remove root view controller navigation bar
self.navigationController?.navigationBar.isHidden = true
animationStart = true
animation() //call animation
}

I just Make timer that can use in life. just like image that I push in here, if I go back to main ViewController then I wanna the number that I input in set view controller are tossed to viewController so when I go back to main ViewController and press restart then that number gonna be in text of CountTimeLabel.. but I really don't know how to toss data that I input in another view controller to root viewController... pleas help me.. if I write code like ViewController().variableName = 30 in setViewController, that dose not make things well..(I already know about prepare function but that is not what I am finding..because this is happen when I go back to ViewController(RootViewController)) I will put my code in below..
is it possible to toss data to another view controller from other view controller?

If you're a hobbyist programmer and you just want to "get it done", simply use a static.
Let's say Bottom: UIViewController is the "main", root, view controller at the absolute "base" of your app. no matter what happens "Bottom" is always there.
Say Timer: UIViewController is (any) other view controller you put on top for some reason.
In Bottom, do this
class Bottom: UIViewController, etc ... {
static weak var current: Bottom? = nil
override func viewDidLoad() {
super.viewDidLoad()
Bottom.current = self
}
func testing() {
print("it works, WTH")
}
Note that in ViewDidLoad, you simply set it.
Next, say you are in Timer, try this:
class Timer: UIViewController, etc ... {
func someFunction() {
Bottom.current.testing() // it's that easy
}
It's that easy.
Note there is a huge amount of confusion about using statics, singletons, and similar approaches in iPhone programming.
(Just for example, many engineers will say "avoid singletons!" This is remarkably confused because in iOS engineering, almost everything is a singleton (notably the app itself (!!!!!), the screen, the GPS, etc etc.)
In any event, as a beginner hobbyist, learn how to use statics (it's simple .. Bottom.current. ... as above), and eventually you can learn about the pros and cons of such things.
I am new to learning swift and my jitterclick style game will not reset after it is complete. Despite already setting the isTimerRunning to false, nothing i have done seems to work. The game is supposed to begin when you press start, start a count down timer from 10, count your number of clicks, and give you a click per second score at the end. This is my first app without a tutorial and appreciate all the help i can get. Thanks
import UIKit
var score = 0
var timer = Timer()
var cps = score / 10
var time = 10.00
var isTimerRunning = false
var isGameComplete = true
var realTime = 0.0
class ViewController: UIViewController {
#IBOutlet weak var resetButton: UIButton!
#IBOutlet weak var clickingButton: UIButton!
#IBOutlet weak var CPSLabelTxt: UILabel!
#IBOutlet weak var timerLabel: UILabel!
#IBOutlet weak var startButton: UIButton!
#IBOutlet weak var scoreLabelTxt: UILabel!
override func viewDidLoad() {
super.viewDidLoad()
resetButton.isHidden = true
resetButton.isEnabled = false
CPSLabelTxt.isHidden = true
scoreLabelTxt.isHidden = false
scoreLabelTxt.text = "Press Start to begin"
}
#IBAction func resetButtonDidTap(_ sender: Any){
resetButton.isEnabled = false
startButton.isEnabled = true
time = 10.0
timerLabel.text = "10.00"
isTimerRunning = false
}
#IBAction func clickingButtonDidTap(_ sender: Any) {
if !isGameComplete {
score += 1
scoreLabelTxt.text = "\(score)"
}
}
//Start button is pressed
#IBAction func startButtonDidTap(_ sender: Any) {
isGameComplete = false
startButton.isEnabled = false
//Count down timer begins
if !isTimerRunning{
timer = Timer.scheduledTimer(timeInterval: 0.01, target: self, selector: #selector(runTimer), userInfo: nil, repeats: true)
isTimerRunning = true
}
}
//logic for timer
#objc func runTimer(){
time -= 0.01
realTime = round(100 * time) / 100
timerLabel.text = "\(realTime)"
if time < 0.0 {
isTimerRunning = false
timerLabel.text = "0.00"
isGameComplete = true
resetButton.isHidden = false
CPSLabelTxt.isHidden = false
scoreLabelTxt.isHidden = false
scoreLabelTxt.text = "\(score)"
CPSLabelTxt.text = "\(cps)"
time = -2
}
}
}
Put timer.invalidate() in your resetButtonDidTap(_ sender: Any) function. This stops the timer from running.
I got an issue.
I want to set a timer that could disable the 6 large buttons of my ViewController2.
For example : Until the timer reach 100, it's not possible to click on the buttons Clue1Button,Clue2Button,Clue3Button,Clue4Button,Clue5Button,Clue6Button
Until the timer reach 200, it's not possible to click on the buttons 2,3,4,5,6 ...
How should I do it ? I tried several times, but I failed each time. Thanks for your help

Try to make my button disable/enable
What you may want to do is:
//Add variable that will count how many times Timer was repeated.
var timerCount = 0
//Create timer
Timer.scheduledTimer(withTimeInterval: 100, repeats: true) { t in
//After first 100 sec passed, timer will get triggered and enable the buttons you want.
button1.isEnabled = true
button2.isEnabled = true
//After another 100 passed, timer will enable other buttons
if timerCount == 1 {
button3.isEnabled = true
button4.isEnabled = true
t.invalidate()
}
//Adds 1 to timer count
timerCount += 1
}
I am trying to add the UIPagecontrol using NSTimer for images sliding.
but not able to get it.
I have tried something which is given below.
import UIKit
class ViewController: UIViewController {
#IBOutlet weak var pagecontrol: UIPageControl!
#IBOutlet weak var imgview: UIImageView!
var tTime: Timer!
var index = 0
var items = ["1.png","11.png","111.png","1111.png"]
override func viewDidLoad() {
super.viewDidLoad()
configurePageControl()
let timer = Timer.scheduledTimer(timeInterval: 0.4, target: self, selector: #selector(self.update), userInfo: nil, repeats: true)
// Do any additional setup after loading the view, typically from a nib.
}
func configurePageControl() {
self.pagecontrol.numberOfPages = items.count
self.pagecontrol.currentPage = 0
self.pagecontrol.tintColor = UIColor.red
self.pagecontrol.pageIndicatorTintColor = UIColor.black
self.pagecontrol.currentPageIndicatorTintColor = UIColor.green
}
#objc func update() {
index = index + 1
}
}
If anyone helps,Would be great.Thank in advance.
Change your
#objc func update() {
index = index + 1
}
function to
#objc func update() {
index = index + 1
if index >= items.count {
index = 0
}
imgview.image = UIImage(named: items[index])
pagecontrol.currentPage = index
}
And it should work.
I'm making an app and using NSTimer to make the timer in my app.But I need the NSTimer to run when the scene start.I have two scene in my app a homescreen and the app it's self here is my code viewcontroller.swift (The second scene the first scene in empty) And btw it's my 3 day using swift and i'm in middle school ;).

Swift 2.x :
func DisplayTimer() {
Timer = NSTimer.scheduledTimerWithTimeInterval(1.0, target:self, selector: #selector(updateTimer), userInfo: nil, repeats: true)
}
func updateTimer() {
if Counter != 0 { TimerLabel.text = "\(Counter -= 1)"

}
}

DisplayTimer()
TimerLabel.text = "\(Counter)"
...
}
If you want to start your timer when the scene loads call DisplayTimer() under
override func viewDidLoad() when the view is loaded
Also if you want to update your label every second, the selector in your NSTimer is calling updateCounter not updateTimer
