Swift 3 - Uibutton Adding Settitle from Plist and Database

Swift 3 - UIButton adding setTitle from plist and database

What you need to do is first create an array with all your target letters (shuffled and added random letters) and then run over that array to update the button titles.

Start by filling a 14 value array with random letters:

var presentedLetters : [String] = [String]()
var availableLetters : [String] = pathDict?.object(forKey: "Letters") as! [String]

var availableLetterIndexes : [Int] = Array(0..<availableLetters.count)

for letterAt in 0 ..< 14
{
    let randomIndex : Int = Int(arc4random_uniform(UInt32(availableLetterIndexes.count)))
    var charIndex : Int = availableLetterIndexes[randomIndex]

    presentedLetters.append(availableLetters[charIndex])

    availableLetterIndexes.remove(at: randomIndex)
}

Generate available positions for the answer string:

var availableIndexes : [Int] = Array(0..<presentedLetters.count)

Then go over your letters from the db and add them in random places inside the target array (while remembering added indexes to prevent overriding letters):

var addedAnswerIndexes : [Int] = [Int]()

let answerString = data.ans // ans is a row in the SQLite database 
let answerCharacters = answerString.characters.map{String($0)}

for answerCharAt in answerCharacters
{
    let randomIndex : Int = Int(arc4random_uniform(UInt32(availableIndexes.count)))
    var charIndex : Int = availableIndexes[randomIndex]

    presentedLetters[charIndex] = answerCharAt

    availableIndexes.remove(at: randomIndex)
}

And then presentedLetters will have an array of all relevant values.

EDIT:

To add the titles to the buttons, just go over presentedLetters array:

        for i in 1...14 {

            let tileButton = UIButton(type: .roundedRect)
            tileButton.setTitle(presentedLetters[i-1], for: .normal)

            ......

        }
    }

Good luck!

Swift 3 - CGAffineTransform does not work

In the function, instead of using sender.transform, use btnButton.transform, this is caused because you are out of scope, and sender might be dismissed, which causes the animation to dismiss.

Another option is to strongly hold the object:

let tappedButton : UIButton = sender

and then use tappedButton

EDIT

I mean something like this:

func moveButton(sender: UIButton) {

    if ((sender.tag == 1) && (sender == self.btnButton)) {

        if self.btnButton.transform == CGAffineTransform.identity {

            UIView.animate(withDuration: 0.5, animations: 
                self.btnButton.transform = CGAffineTransform(translationX: 50, y: 100)

            })
        }                
    }
}

EDIT - 2

According to your code there are 2 problems:

1. All 14 buttons are stacked 1 on top of the other, meaning button 14 will be the topmost button instead of button 1.

2. You are not setting the tag, and then it fails in your check in moveButton:

   func createButtonPuzzle(id: Int) {

    for i in 1...14 {
   
           let btnButton = UIButton(type: .roundedRect)
           btnButton.frame = CGRect(x: self.view.frame.size.width / 2, y: self.view.frame.size.height / 2, width: 100, height: 100)
           btnButton.backgroundColor = .blue
           btnButton.setTitle("iButton", for: .normal)
           btnButton.addTarget(self, action: #selector(moveButton(sender:)), for: .touchUpInside)
   
           **btnButton.tag = i // This is missing **
   
           view.addSubview(btnButton)   
    }
   

   }

And then this fails:
if sender.tag == 1 {

So to test it and see it working, first you need to either go from 14 to 1 and just from 1..<2 or reposition the buttons in different positions so that it will actually work.

Then the tags will be set and when button with tag 1 will be tapped it will work

Swift 3 - Expression was too complex to be solved in reasonable time; consider breaking up the expression into distinct sub-expressions

Expression was too complex to be solved in reasonable time; consider
breaking up the expression into distinct sub-expressions

So as said, break it:

let preAxis1: GCFloat = (width / 2) - (totalWidth / 2) 
let preAxis2: GCFloat = (tar * targetWidth) + (tar * 5) + 20
let xAxis : CGFloat = preAxis1 + preAxis2

Now, that reveals another (the real one) issue, and what you are doing doesn't make sense:

Binary operator '*' cannot be applied to operands of type 'Character'
and 'CGFloat'

So tar is a Character, not a "numeral".
There is no sense about using it in the calculation of xAxis. What you want in fact is the index of it.

Instead of for tar in data.ans.characters {, you can do it like that:

for (indexTar, tar) in data.ans.characters.enumerated() {

You are iterating all the characters in data.ans and indexTar is the current index and tar the Character.
So by replacing tar with indexTar in the previous calculation of xAxis it makes more sense and should work.

Title and subtitle with different fontsize for UIButton

Try this

UIButton *btn = [UIButton buttonWithType:UIButtonTypeRoundedRect];
[btn setFrame:CGRectMake(20 , 13, 200, 85)];
UILabel *title = [[UILabel alloc]initWithFrame:CGRectMake(8, 8, 185, 30)];
[title setBackgroundColor:[UIColor clearColor]];
[title setFont:[UIFont fontWithName:@"Chalkboard" size:14]];
[title setFont:[UIFont boldSystemFontOfSize:18]];
title.text=@"This is the title";
[title setTextColor:[UIColor blackColor]];
[btn    addSubview:title];

UILabel *subtitle = [[UILabel alloc]initWithFrame:CGRectMake(8, 20, 185, 30)];
[subtitle setBackgroundColor:[UIColor clearColor]];
[subtitle setFont:[UIFont fontWithName:@"Helvetica" size:14]];
subtitle.text=@"This is the sub";
[subtitle setTextColor:[UIColor blackColor]];
[btn    addSubview:subtitle];

[title  release];
[subtitle release];

[self.view addSubview:btn];

Can't change custom UIFont size on the UIButton

Interestingly enough, it turned out to be my Mac. When I gave my friend to install them, he had no issues.
My Mac is on the old side, so maybe this was the reason. Here are the specs:

**Mac:** MacBook Pro 15" (Late 2008)
**Processor:**  2.4 GHz Intel Core 2 Duo
**Memory:** 4 GB 1067 MHz DDR3
**Graphics:** NVIDIA GeForce 9600M GT 256 MB

constant ... inferred to have type '()?', which may be unexpected

Your developerButton is the result of the text assignment text = "developer", which returns Void (nothing, ()). The assignment is conditional and that's why you are getting Void? (or ()?).

Split your two assignments correctly.

let developerButton = UIButton(type: .system)
developerButton.titleLabel?.text = "developer"

Also note that you should use setTitle instead of setting title text directly:

let developerButton = UIButton(type: .system)
developerButton.setTitle("developer", for: .normal)
