BindKit
A simple to use two-way data binding framework for iOS. Only one API to learn.
Supports Objective-C, Swift 5, Xcode 10.2, iOS 8 and above.
Ships as a cocoapod or static library ready for you to link into your app (or you can include the source directly into your project). The static library is built as a 'fat' library and includes the following architectures: i386, x86_64, armv7s, armv7, arm64 and bitcode.
Looking for an older version?
Tagged version 1.0.0 supports Objective-C, Swift 3 and 4, Xcode 8, 9 and 10, iOS 8 and above.
Currently supported views
The following views are supported directly by BindKit:
View class | View properties |
---|---|
UIBarButtonItem | enabled |
UIButton | enabled, hidden |
UIDatePicker | date, enabled, hidden |
UIImageView | image, hidden |
UILabel | text, attributedText, hidden |
UIPageControl | currentPage, numberOfPages, enabled, hidden |
UISegmentedControl | selectedSegmentIndex, enabled, hidden |
UISlider | value, enabled, hidden |
UIStepper | value, enabled, hidden |
UISwitch | on, enabled, hidden |
UITextFieldText | text, attributedText, enabled, hidden |
UITextView | text, attributedText, editable, hidden |

Binding
Data binding is two-way - any changes to your models properties are automatically applied to your views properties and vice versa.
There is only one API to learn:
Objective-C
[model bindObjectSel: @selector(addressStr) toView: addressTextField viewKey: UITextFieldText];
Swift
model.bindObjectKey(#keyPath(model.addressStr), toView: addressTextField, viewKey: UITextFieldText)
Just a few simple rules
The following rules apply when using BindKit with Swift:
- Your model object must inherit from
NSObject
. - Your models properties that participate in binding need to be marked
@objc dynamic
.
See under the hood for implementation details.
Example
Swift
class LogonModel: NSObject {
@objc dynamic var username: String!
@objc dynamic var password: String!
@objc dynamic var logonEnabled: Boolean
override func boundPropertiesDidUpdate() {
logonEnabled = validate()
}
func validate() -> Boolean
guard username!.trimmingCharacters(in: CharacterSet.whitespaces).count > 0 else { return false }
guard password!.trimmingCharacters(in: CharacterSet.whitespaces).count > 0 else { return false }
return true
}
}
class LogonController: UITableViewController {
@IBOutlet weak var usernameTextField: UITextField!
@IBOutlet weak var passwordTextField: UITextField!
@IBOutlet weak var logonButton: UIButton!
var model = LogonModel()
override func viewDidLoad() {
model.bindKey(#keyPath(model.username), view: usernameTextField, viewKey: UITextFieldText)
model.bindKey(#keyPath(model.password), view: passwordTextField, viewKey: UITextFieldText)
model.bindKey(#keyPath(model.logonEnabled), view: logonButton, viewKey: UIButtonEnabled)
}
}
Adding BindKit to your app (Manual integration)
- Link
libBindKit.a
into your app - Configure
Header Search Paths
to allow Xcode to findBindKit.h
andBindKitVendor.h
- Add
-ObjC
and-all_load
toOther Linker Flags
Adding BindKit to your app (Cocoapods integration)
- If you have not already created a Podfile for your application, create one now:
pod init
- Add the following into your Podfile:
pod 'BindKit'
- Save the file and run:
pod install
Building
Whilst the libBindKit.a static library is prebuilt and included in the repository, if you need to rebuild then execute the following command:
./buildlibrary.sh
The resulting static library and header files will be placed into the release
directory.
The build script currently assumes Xcode 10.2/SDK12.2. If you are using a different Xcode build chain, tweak the IOSSDK_VER
variable in the build script as appropriate.
Under the hood
Model
Model properties that participate in binding are monitored for changes using Key-Value-Observing (KVO). For this reason model objects must inherit from NSObject
, and if using Swift, properties must be marked with @objc dynamic
.
View
Views that participate in binding are dynamically subclassed at runtime. There is one dynamic subclass implemented for each supported view. Depending on the view, different methods for monitoring changes are required: target-action, delegation or notifications.
View not supported? Submit a pull request with your changes to add the property or class, or use the Vendor API to add custom functionality in your own app.
