iOSKickStart

A set of extended UIKit features to kickstart any iOS project.

Example Project

To run the example project, clone the repo, and run pod install from the Example directory first.

About

A beautiful project template to kick start any iOS project. The target is to avoid recoding for features like UIView rounded rect designables or a simple scrolling form. Please contribute to this project to fill up with a standard set of features frequently needed.

Features & Implementations

1. Localization

(a) Set Language

(1) Set and Switch application locale programmetically.

// Bundle.setLanguage(language: String!)
Bundle.setLanguage("bn")

(2) Get application locale programmetically.

// Bundle.getLanguage()
let currentLanguage = Bundle.getLanguage()

(3) Update current view with changed locale.

You will have to reload Main storyboard

or,
Reload current viewing ViewController

func forceReload() {
    let storyBoard : UIStoryboard = UIStoryboard(name: "Main", bundle:nil)
    let destVC = storyBoard.instantiateViewController(withIdentifier: <"ViewControllerIdentifier">) as! <ViewControllerClass>
    let navC = self.navigationController;
    navC?.popToRootViewController(animated: true)
    navC?.pushViewController(destVC, animated: true)
}

(b) Localization from storyboard

With Localizable.strings (Locale) key sting into interface builder.

(1) UILabel

.localizedTextKey = <localizableKey>

(2) UITextField

.localizedPlaceholderKey = <localizableKey>

(3) UIBUtton

.localizedTitleKey = <localizableKey>

(4) UITabBarItem

.localizedTitleKey = <localizableKey>

(5) UIViewController.title

.localizedTitleKey = <localizableKey>

2. User intput form (Scrollview)

(a) Label bounds.height to font ratio

fontToHeightRatio = <fractionLessThanZero>

(b) TextField left, right padding

textField.leftPadding = <paddingInPoints>
textField.rightPadding = <paddingInPoints>

(c) Keyboard configuration

Default keyboard config enum in interfacebuilder to choose easily and avoid keyboard config mistakes.

Configuration options

private enum TextFieldKeyboardConfig: String {
    case email
    case name
    case password
    case comment
}

To set keyboard configuration

keyboardConfig = <option>

(d) CodeInputTextField Code input

(1) Set length and code placeholder
codeLengthAndChar = <length,placeholder>

e.g: codeLengthAndChar = "6,●"

(2) Implement UITextFieldDelegate

// MARK: - UITextFieldDelegate

func textFieldDidBeginEditing(_ textField: UITextField) {
    if let textFld = (textField as? CodeInputTextField) {
        textFld.observeCodeInputDidBegin()
    }
}

func textField(_ textField: UITextField, shouldChangeCharactersIn range: NSRange, replacementString string: String) -> Bool {
    // Code ...

    if let textFld = (textField as? CodeInputTextField) {
        return textFld.observeCodeInput(shouldChangeCharactersIn: range, replacementString: string)
    }

    return true
}

This is how it looks

(e) Input form scrollview behavior

Step 01

To make scrollview to act as an input form
Set scrollview user defined runtime attributes

// User defined runtime attributes
actAsInputForm = true

To dismiss keyboard on tap
Set scrollview.view (view under scrollview on wich the form fields resided) user defined runtime attributes

// User defined runtime attributes
endEditingOnTap = true

Step 02

Send actions to scrollview

@IBOutlet weak var scrollView: ScrollView!

override func viewWillAppear(_ animated: Bool) {
    super.viewWillAppear(animated)

    scrollView.parentViewControllerWillAppear()
}

override func viewWillDisappear(_ animated: Bool) {
    super.viewWillDisappear(animated)

    scrollView.parentViewControllerWillDisappear()
}

// MARK: - UITextFieldDelegate

func textField(_ textField: UITextField, shouldChangeCharactersIn range: NSRange, replacementString string: String) -> Bool {
    scrollView.scrollControlRectToVisible(textField)

    return true
}

2. UINavigationController

UINavigationController+Extension

isNavBarHidden IBInspectable.

5. Define once use everywhere global constants.

1. Navigation: Cross dissolve and reverse push pop

2. UIColor init with hex value.

3. UIView corner-radius and colored-border IBInspectables.

UIView+Extension

bgColorKey cornerRadius applyStandardCornerRadius makeRoundedCorners borderWidth borderColor endEditingOnTap gradHexColors

11. UIBUtton+Extension

localizedTitleKey
keyNormalTxtColor
keyDisabledTxtColor
UIButton adoptive font size

fontToHeightRatio
numberOfLines
adjustFontSize // adjustsFontSizeToFitWidth

OR

button.fontToHeightRatio = 0.35
button.numberOfLines = 1
button.adjustFontSize = true

13. UILabel bounds.height to font size ratio

OR

label.fontToHeightRatio = 0.6

14. UIViewController titleImage IBInspectable

OR

viewController.titleImage = UIImage(named: "image_name")

Limitations

1. You have to extend or use sub classes declared here against Apple's base classes.

This is just a basic work. Please contribute, expand and Enjoy...
