Connecting methods to buttons and initializing

I think the issue was by ths following , this isn't the way you init the ABPeoplePickerNavigationController simply write :
code :
    func showAddressBook() {

    var addBook = ABPeoplePickerNavigationController()
    self.presentViewController(addBook, animated: true) { () -> Void in}
}

How to initialize all methods inside a namespace?namespaces javascript INITIALIZING ALL methods

it fixes the issue I've not tested this, but something like this should prove useful. Every function in JavaScript has a call() method for invoking it. Then:
code :

$(document).ready(function() {
  $.each(myNamespace, function(index, obj) {
    if (typeof(obj) == 'function')
    {
       obj.call(myNamespace);
    }
  });
});
Initializing With Instance Methods versus Class Methods

To fix this issue The convenience constructor (+ version) will return an autoreleased value. Under ARC, this autorelease may be optimized away if the result is immediately assigned to a strong reference (using the objc_autoreleaseReturnValue/objc_retainAutoreleasedValue optimization).
The only time you need to be careful is with tight loops where using the + version may lead to lots of autoreleased objects getting created. If profiling reveals this to be a problem, consider using alloc+init instead inside such loops.
Initializing and remembering radio buttons

With these it helps I have read a lot of posts here and elsewhere about remembering radio buttons. I have also read a lot of posts about initialising one radio button. What I have not read a lot of is combining the two. I am wanting to do it within the input statement if possible.
code :
<input type="radio" name="typ" value="exact" <?php echo ($_GET['typ'] =="exact")?"checked":'' ?>>Exact
<input type="radio" name="typ" value="exact" <?php echo ($_GET['typ'] =="starts")?"checked":'' ?>>Starts with
<input type="radio" name="typ" value="exact" <?php echo ($_GET['typ'] =="sounds")?"checked":'' ?>>Soundex

<input type="submit" value="Find" /></td></tr>
Swift 3 Initializing buttons

wish help you to fix your issue Where does one put button initialization code for controls. It won't work in ViewController.swift correct? because I need it to init immediately, not after a button is pressed. , 'buttonAdd' is a function, not a button.
try this code.
code :
    if let button = sender as? UIButton
    {
        button.backgroundColor = UIColor.cyan

        // button.backgroundColor = .clear
        button.layer.cornerRadius = 15
        button.layer.borderWidth = 1
        button.layer.borderColor = UIColor.black.cgColor
    }
    override func viewDidLoad()
    {
        super.viewDidLoad()

        let btn = UIButton(type: .custom)
        btn.frame = .init(x: 100, y: 100, width: 100, height: 30)
        btn.setTitle("Hello", for: .normal)
        btn.backgroundColor = UIColor.cyan
        btn.layer.cornerRadius = 15
        btn.layer.borderColor = UIColor.black.cgColor
        btn.layer.borderWidth = 1

        // you must call this for rounded corner
        btn.layer.masksToBounds = true
        self.view.addSubview(btn)
    }
@IBOutlet weak var btn: UIButton!
override func viewDidLoad()
{
    super.viewDidLoad()

    btn.layer.cornerRadius = 15
    btn.layer.borderColor = UIColor.black.cgColor
    btn.layer.borderWidth = 1

    // you must call this for rounded corner
    btn.layer.masksToBounds = true
}
Undefined 'err' in SQLX when initializing connecting to a database

Undefined 'err' in SQLX when initializing connecting to a database

This might help you This is very basic Go. You should do the tour. In particular have a look at https://tour.golang.org/basics/10. Not that in Go you have to watch for the subtle difference between = and :=.
But in brief you are using err before it is declared. You can either declare it first:
code :
  var err error
  db, err := sqlx.Connect("mysql", connection)
  userJson, err := json.Marshal(response)
  if err != nil {
    panic(err)
  }
  db, err = sqlx.Connect("mysql", connection)
  if err != nil {
    panic(err)
  }
