Features

• Supports AutoLayout and has intrinsic size. Optionally set a height to make the boxes taller or a width to add more inner spacing between boxes.

CocoaPods is a dependency manager for Cocoa projects.

CocoaPods 0.36 adds supports for Swift and embedded frameworks. You can install it with the following command:

$ gem install cocoapods

To integrate PinEntryView into your Xcode project using CocoaPods, specify it in your Podfile:

pod 'PinEntryView'

Then, run the following command:

$ pod install

In case Xcode complains ("Cannot load underlying module for PinEntryView") go to Product and choose Clean (or simply press ⇧⌘K).

If you prefer not to use CocoaPods, you can integrate PinEntryView into your project manually.

• Supported build target - iOS 8.0+ (Xcode 8.3.2+)

PinEntryView is state based. To configure the view, simply update the state value with whatever values you'd like, and re-set the state:

1. First you should set up the PinEntryView and provide an initial state:

var pinEntryView = PinEntryView()
pinEntryView.state = PinEntryView.State(pin: "ACCEPT",
                                        allowsBackspace: true,
                                        showsPlaceholder: true,
                                        placeholderTextColor: .lightGray,
                                        allowsAllCharacters: false,
                                        focusBorderColor: .black,
                                        inactiveBorderColor: .lightGray,
                                        completedBorderColor: .green,
                                        errorBorderColor: .red,
                                        returnKeyType: .done)

2. Once set, you can optionally adjust individual parameters in the state:

Reassigning one var can be done in line:

pinEntryView.state?.returnKeyType = .next

or

Group up reassigning multiple vars that way only one update (PinEntryView.update()) cycle is made:

var state = pinEntryView.state
state?.completedBorderColor = .clear
state?.showsPlaceholder = false
pinEntryView.state = state
