An easy-to-use, drop-in replacement to the iOS 11 Haptic Feedback APIs, compatible with Objective-C and Swift Projects.
Always runs on the main thread, interoperable with Objective-C, and with automatic memory management for different types of feedback generators. Feedback generators are re-used if they are of the same type, as they are stored in HapticCache.
No need to manually manage different types of generators, simply instantiate the Haptic class, and use as shown below.
Drag and drop the PKHapticFeedback files into your project to get started. (FeedbackGenerating.swift, Haptic.swift, HapticCache.swift, HapticTuple.swift, and HapticType.swift)
Then import the framework as follows, for Objective-C Projects:
#import "PKHapticFeedback-Swift.h"
Or as follows for Swift projects:
import "PKHapticFeedback"
To get started, instantiate the Haptic class:
let haptic = Haptic()
Or,
Haptic *haptic = [[Haptic alloc] init];
The different types of haptic feedback are listed inside HapticType. A HapticTuple couples a type with its generator, and is used by Haptic to use the cached generators.
Example of generating feedback, in Swift:
self.haptic.generateFeedback(hapticType: HapticType.impact(.heavy))
self.haptic.generateFeedback(hapticType: HapticType.impact(.medium))
self.haptic.generateFeedback(hapticType: HapticType.impact(.light))
self.haptic.generateFeedback(hapticType: HapticType.notification(.warning))
self.haptic.generateFeedback(hapticType: HapticType.notification(.error))
self.haptic.generateFeedback(hapticType: HapticType.notification(.selection))
self.haptic.generateFeedback(hapticType: HapticType.selection)
In Objective-C:
[self.haptic generateFeedbackWithType:CompatibleHapticTypeHeavy];
[self.haptic generateFeedbackWithType:CompatibleHapticTypeMedium];
[self.haptic generateFeedbackWithType:CompatibleHapticTypeLight];
[self.haptic generateFeedbackWithType:CompatibleHapticTypeWarning];
[self.haptic generateFeedbackWithType:CompatibleHapticTypeError];
[self.haptic generateFeedbackWithType:CompatibleHapticTypeSuccess];
[self.haptic generateFeedbackWithType:CompatibleHapticTypeSelection];
Preparing the generator can reduce latency when triggering feedback. This is particularly important when trying to match feedback to sound or visual cues.
Example usage:
self.haptic.prepareFeedbackGenerator(forHapticType: HapticType.impact(.light))
In Objective-C:
[self.haptic prepareForFeedbackWithType:CompatibleHapticTypeSelection];
Unit tests have been included which make use of dependency injection, stubbing, and mocks. These testing functions test if feedback generation takes place the expected number of times in the case of multiple calls, whether the captured haptic type is correct, and also if preparation and generation of feedback occurs in the main thread.
You can use this freely in your projects as you wish but please email me at some point at pranavkasetti@gmail.com just so I can see how you have used it, thanks.
