FormChangeable

Easy to move from UITextField/UITextView to next UITextField/UITextView written in Swift.

Description

Some ViewController have four forms(text field or text view) like nameTextField, emailTextField, passwordTextField and profileTextView.
When they enter their name in and press ‘Next’ on the keyboard, I want this to automatically move to the next Form.
So, I will implement like below:

class ViewController: UIViewController, UITextFieldDelegate {
    @IBOutlet private weak var nameTextField: UITextField!
    @IBOutlet private weak var mailTextField: UITextField!
    @IBOutlet private weak var passwordTextField: UITextField!
    @IBOutlet private weak var profileTextView: UITextView!

    func textFieldShouldReturn(textField: UITextField) -> Bool {
        textField.resignFirstResponder()
        if textField == nameTextField {
            mailTextField.becomeFirstResponder()
        } else if textField == mailTextField {
            passwordTextField.becomeFirstResponder()
        } else if textField == passwordTextField {
            profileTextView.becomeFirstResponder()
        } else {
            return true
        }
        return false
    }
}

or,

class ViewController: UIViewController, UITextFieldDelegate {
    @IBOutlet private weak var nameTextField: UITextField!
    @IBOutlet private weak var mailTextField: UITextField!
    @IBOutlet private weak var passwordTextField: UITextField!
    private var textfields = [UITextField]()

    override func viewDidLoad() {
        super.viewDidLoad()
        textfields += [nameTextField, mailTextField, passwordTextField]
    }

    func textFieldShouldReturn(textField: UITextField) -> Bool {
        textField.resignFirstResponder()
        let tag = textField.tag
        let nextIndex = tag + 1
        if nextIndex < textfields.count {
            textfields[nextIndex].becomeFirstResponder()
            return false
        }
        return true
    }
}

…It’s not very good.

Problems

Need to check forms. 😞
Use tag…😞

They are bother!!!

Solution

FormChangeable can resolve these problems.

Feature

Don’t have to check form anymore.
Don’t use tag.
No complex settings.
Can move both UITextFIeld and UITextView
Move to next/prev form if next/prev form exists.
If next/prev form don’t exists, only close keyboard in current form.

Usage

[1] setup next/prev form

import FormChangeable

class ViewController: UIViewController {
    @IBOutlet private weak var nameTextField: UITextField!
    @IBOutlet private weak var mailTextField: UITextField!
    @IBOutlet private weak var passwordTextField: UITextField!
    @IBOutlet private weak var profileTextView: UITextView!
    override func viewDidLoad() {
        super.viewDidLoad()
        nameTextField.nextForm = mailTextField
        mailTextField.nextForm = passwordTextField
        passwordTextField.nextForm = profileTextView
    }
}

or,

import FormChangeable

class ViewController: UIViewController {
    @IBOutlet private weak var nameTextField: UITextField!
    @IBOutlet private weak var mailTextField: UITextField!
    @IBOutlet private weak var passwordTextField: UITextField!
    @IBOutlet private weak var profileTextView: UITextView!
    override func viewDidLoad() {
        super.viewDidLoad()
        let forms: [FormChangeable] = [nameTextField, mailTextField, passwordTextField, profileTextView]
        forms.registerNextForm()
    }
}

[2] Implement UITextFieldDelegate’s func textFieldShouldReturn(textField:)
[3] Implement UITextViewDelegates func textView(textView:, shouldChangeTextInRange:, replacementText:)

class ViewController: UIViewController, UITextFieldDelegate {
    func textFieldShouldReturn(textField: UITextField) -> Bool {
        textField.changeToNextForm()
        return false
    }

    func textView(textView: UITextView, shouldChangeTextInRange range: NSRange, replacementText text: String) -> Bool {
        if text == "\n" {
            textView.changeToNextForm()
            return false
        }
        return true
    }
}
