How do I set up NgKeyboardTracker without CocoaPods?

Manually add the files from the NgKeyboardTracker folder to your project and link the UIKit framework. Then, start tracking by calling [[NgKeyboardTracker sharedTracker] start] in your app delegate's didFinishLaunchingWithOptions method.

NgKeyboardTracker vs native iOS keyboard handling: which is easier?

NgKeyboardTracker simplifies keyboard tracking by centralizing properties and enabling advanced behaviors, while native handling requires manual notification management. For simple apps, native APIs might suffice, but NgKeyboardTracker reduces boilerplate for complex interactions.

Can I use NgKeyboardTracker in a Swift project?

Yes, but it requires Objective-C bridging headers, which can add setup overhead. This makes it less seamless compared to Swift-native keyboard libraries.

How to implement iMessage-style keyboard dismissal with NgKeyboardTracker?

Use NgPseudoInputAccessoryViewCoordinator by creating it in a custom view, setting the input accessory view, and configuring UIScrollView's keyboard dismiss mode to interactive. The demo app provides a full example for layout adjustments.

What keyboard animation properties does NgKeyboardTracker track?

It tracks animationDuration, animationCurve, and derived animationOptions, along with frames like beginFrame and endFrame, allowing synchronized UI updates during keyboard transitions.

Is NgKeyboardTracker still maintained for recent iOS versions?

The library targets iOS 7+ and may work with newer versions, but the README shows no recent updates, so compatibility with latest iOS APIs should be verified through testing.

What is NgKeyboardTracker?

NgKeyboardTracker is an Objective-C library for iOS that tracks the keyboard's frame, animation properties, and appearance state. It solves the problem of manually handling keyboard notifications and calculating keyboard frames, providing a centralized way to build interfaces that respond dynamically to keyboard changes.

Target Audience

iOS developers building apps that require responsive UI adjustments based on keyboard visibility, such as chat apps, forms, or any input-heavy interfaces.

Value Proposition

Developers choose NgKeyboardTracker because it encapsulates complex keyboard tracking logic into a simple, reusable library, supports advanced behaviors like iMessage-style interactive dismissal, and reduces the boilerplate code typically needed for keyboard handling.

Overview

Objective-C library for tracking keyboard in iOS apps.

Use Cases

Best For

Implementing chat interfaces with interactive keyboard dismissal
Building forms that adjust layout when the keyboard appears
Creating custom input accessory views that persist during keyboard interactions
Tracking keyboard animation properties for synchronized UI updates
Developing iOS 7+ apps that need precise keyboard frame information
Reducing boilerplate code for keyboard notification handling

Not Ideal For

Swift-only projects that prefer not to introduce Objective-C dependencies
Apps with simple form inputs that can rely on iOS's built-in UITextField adjustments
Teams needing extensive documentation and active community support for frequent updates

Pros & Cons

Pros

Centralized Keyboard Properties

Provides easy querying of keyboard frame, animation duration, and curve from anywhere in the app, as demonstrated in the usage section for properties like currentFrame and animationOptions.

Delegate-Based Real-Time Updates

Enables immediate UI adjustments by implementing NgKeyboardTrackerDelegate, allowing apps to respond dynamically to keyboard appearance and frame changes.

Advanced UI Behaviors

Facilitates iMessage-style interactive keyboard dismissal with persistent input accessory views using NgPseudoInputAccessoryViewCoordinator, as outlined in the demo for iOS 7+ apps.

Reduced Boilerplate Code

Encapsulates complex keyboard notification handling into a simple start/stop interface, eliminating manual setup for tracking keyboard events across the app.

Cons

Objective-C Dependency

As an Objective-C library, it requires bridging headers for Swift projects, adding integration complexity and potentially deterring modern iOS developers.

Sparse Documentation

The README lacks detailed API references and comprehensive examples, forcing reliance on the demo app for advanced implementations like NgPseudoInputAccessoryViewCoordinator.

iOS 7+ Focus Limitations

Advanced features like iMessage-style behavior are tailored for iOS 7, which may not fully utilize newer iOS APIs or be optimized for the latest iOS versions.
