class ViewController: UITableViewController {
#IBOutlet weak var Name: UITextField!
#IBOutlet weak var nameLabel: UILabel!
#IBOutlet weak var Phonenumb: UITextField!
#IBOutlet weak var phoneLabel: UILabel!
#IBOutlet weak var Phone: NSLayoutConstraint!
#IBOutlet weak var Date: UITextField!
#IBOutlet weak var dateLabel: UILabel!
#IBOutlet weak var County: UITextField!
#IBOutlet weak var killCountLabel: UILabel!
#IBOutlet weak var killDate: UITextField!
#IBOutlet weak var killDateLabel: UILabel!

#IBOutlet weak var addressLabel: UILabel!
#IBOutlet weak var page2Button: UIButton!
#IBAction func saveTextToVar(sender: UIButton) {
var nameText: Name.text // problem is here (Error: Use of undeclared type 'Name')
}
My app is a simple form app that will send me people's forms when they fill them out. What I would like it to do is when I push the button (page2Button) is for it to send me to the second tableViewController and save all of my textFields to a variable then send them to my Firebase. (I have not installed Firebase yet).
My question is why is there an undeclared type Error when I already have a var named Name? And how do I fix it?

Is it possible to make a label as a variable? I have multiple labels:
#IBOutlet weak var FL1at0: UIButton!
#IBOutlet weak var FL1at3: UIButton!
#IBOutlet weak var FL1at6: UIButton!
#IBOutlet weak var FL1at9: UIButton!
#IBOutlet weak var FL1at12: UIButton!
#IBOutlet weak var FL1at15: UIButton!
#IBOutlet weak var FL1at18: UIButton!
#IBOutlet weak var FL1at21: UIButton!
Sample Function:
else
{
UserDefaults.standard.set(true, forKey: "RedFl1")
self.FL1at0.setTitleColor(UIColor.red, for: .normal); self.ProgressUpdate()
}
Is there a way to set the table in a way to work like this:
self.FL1at"\(TimeStamp)".setTitleColor(UIColor.red, for: .normal)//TimeStamp comes from function
Try this:
let dict: Dictionary<String, UIButton> = ["FL1at0": FL1at0, "FL1at3": FL1at3, ...]
let x = "FL1at\(TimeStamp)"
if let y = dict[x] as? UIButton {
y.setTitleColor(UIColor.red, for: .normal)
}
You can't.
But you can save buttons in a dictionary:
var dic: [String: UIButton] = ["FL1at0": FL1at0]
then you can use name to access it like:
dic["FL1at\(TimeStamp)"]?.setTitleColorxxxx..
I am creating an animation sequence where when one button is pressed one object fades out. When the same button is pressed again another object fades out. This keeps happening until 8 objects are faded out. I have tried and played around with code and so far have got the code to fade out one object, and two or more at a time, but have not successfully been able to do it as described above. This is my code so far:
import UIKit
class DrinkWaterViewController: UIViewController {
#IBOutlet weak var glassOne: UIImageView!
#IBOutlet weak var glassTwo: UIImageView!
#IBOutlet weak var glassThree: UIImageView!
#IBOutlet weak var glassFour: UIImageView!
#IBOutlet weak var glassFive: UIImageView!
#IBOutlet weak var glassSix: UIImageView!
#IBOutlet weak var glassSeven: UIImageView!
#IBOutlet weak var glassEight: UIImageView!
override func viewDidLoad() {
super.viewDidLoad()
self.glassOne.alpha = 1.0
self.glassTwo.alpha = 1.0
}
#IBAction func drunkOne(_ sender: Any){
if self.glassOne.alpha == 1.0{
UIView.animate(withDuration: 1.5, delay: 0.2, animations:
{self.glassOne.alpha = CGFloat(0.1)}
)
}
}
Put your glasses into an array glasses and add a property to keep track of nextToFade. Then just fade the glasses[nextToFade] and increment nextToFade by 1:
class DrinkWaterViewController: UIViewController {
#IBOutlet weak var glassOne: UIImageView!
#IBOutlet weak var glassTwo: UIImageView!
#IBOutlet weak var glassThree: UIImageView!
#IBOutlet weak var glassFour: UIImageView!
#IBOutlet weak var glassFive: UIImageView!
#IBOutlet weak var glassSix: UIImageView!
#IBOutlet weak var glassSeven: UIImageView!
#IBOutlet weak var glassEight: UIImageView!
// array to hold the glasses so that they can be indexed
var glasses = [UIImageView]()
// index of next glass to fade
var nextToFade = 0
override func viewDidLoad() {
super.viewDidLoad()
// put the glasses into the array
glasses = [glassOne, glassTwo, glassThree, glassFour,
glassFive, glassSix, glassSeven, glassEight]
// make sure they're all visible
glasses.forEach { $0.alpha = 1.0 }
}
#IBAction func drunkOne(_ sender: Any) {
// make sure not to index beyond the end of the array
guard nextToFade < glasses.count else { return }
let glass = glasses[nextToFade]
nextToFade += 1
UIView.animate(withDuration: 1.5, delay: 0.2, animations:
{ glass.alpha = 0.1 }
)
}
}

Swift put multiple IBOutlets in an Array

I've started learning Swift and started off with some simple Games. But every time (depending on the Game) my Code would look like this:
#IBOutlet weak var B1: UIButton!
#IBOutlet weak var B2: UIButton!
#IBOutlet weak var B3: UIButton!
#IBOutlet weak var B4: UIButton!
#IBOutlet weak var B5: UIButton!
#IBOutlet weak var B6: UIButton!
#IBOutlet weak var B7: UIButton!
#IBOutlet weak var B8: UIButton!

#IBOutlet weak var C5: UIButton!
#IBOutlet weak var C6: UIButton!

#IBOutlet weak var C8: UIButton!
#IBOutlet weak var randomPin1: UIButton!
#IBOutlet weak var randomPin2: UIButton!
#IBOutlet weak var randomPin3: UIButton!
#IBOutlet weak var randomPin4: UIButton!
I am pretty unhappy with this, is there a way to use those Buttons (or whatever type it is) without creating an '#IBOutlet weak var name: Type!'? Like with an identifier and then using the identifier to access a Button? Or is that just the normal way to do this? Thanks in Advance!
You should use IB Outlet Collections and store these instance in arrays:

How to loop through view outlets in a UIViewController with Swift?
(2 answers)
Closed 6 years ago.
I have these outlets...
#IBOutlet weak var pill1: UIImageView!
#IBOutlet weak var pill2: UIImageView!
#IBOutlet weak var pill3: UIImageView!
#IBOutlet weak var pill4: UIImageView!
#IBOutlet weak var pill5: UIImageView!
#IBOutlet weak var pill6: UIImageView!
#IBOutlet weak var pill7: UIImageView!
#IBOutlet weak var pill8: UIImageView!
#IBOutlet weak var pill9: UIImageView!
#IBOutlet weak var pill10: UIImageView!
I need to hide all of them in the 'viewDidLoad' function. For example...
self.pill1.isHidden = true
self.pill2.isHidden = true
self.pill3.isHidden = true
etc...
etc....all the way to...
self.pill10.isHidden = true
But instead of writing repetitive lines 10s of times that are very similar, how do I use a 'for loop', or whatever is needed, to make it more cleaner.
For example,
for index in 1...10 {
pill(insert index here somehow).isHidden = true
}
I tried a few different ways, but I was getting errors with string types etc. I am new to this all. Any help appreciated. thank you
You can put the views into an array like this:
for pill in [pill1, pill2, pill3, pill4, pill5, pill6, pill7, pill8, pill9, pill10] {
pill.isHidden = true
}
You could consider using an #IBOutlet collection. In that case, all of your outlets would be wired to the same collection (array) variable:
#IBOutlet var pills: [UIImageView]!
for pill in pills {
pill.isHidden = true
}
I have code like
#IBOutlet weak var emailField: UITextField!
#IBOutlet weak var countryField: UITextField!
#IBOutlet weak var cityField: UITextField!
How can i put all this items to array so i can access each of them in a loop?
#IBOutlet weak var emailField: UITextField!
#IBOutlet weak var countryField: UITextField!
#IBOutlet weak var cityField: UITextField!
...
let array = [emailField, countryField, cityField]
Have a look at the documentation on collection types
edit: you can split the declaration/init of that array
// outside any method
var array = [UITextField]?
// in viewDidLoad
self.array = [emailField, countryField, cityField]
