2 - 8 Zebra Scanner SDK for iOS Developer Guide

Chapter 3 SAMPLE SOURCE CODE

Introduction

This chapter provides detailed examples that demonstrate how to develop iOS applications using the Zebra Scanner Software Development Kit (SDK).

3 - 2 Zebra Scanner SDK for iOS Developer Guide

Accessing the SDK

Create an instance of the Zebra Scanner SDK for iOS API inside of a class that conforms to the ISbtSdkApiDelegate. All available API functions are defined by the ISbtSdkApi Objective-C protocol. A single shared instance of an API object that implements the ISbtSdkApi can be obtained via createSbtSdkApiInstance method of the SbtSdkFactory class.

Code Snippet - Obtain Instance of API

// ....

@import "SbtSdkFactory.h"

// ....

// Get instance to the Zebra Scanner SDK API id <ISbtSdkApi> apiInstance = [SbtSdkFactory createSbtSdkApiInstance];

// Get the SDK version string NSString *version = [apiInstance sbtGetVersion];

NSLog(@"Zebra SDK version: %@\n", version);

Event Handling

The SDK supports a set of asynchronous notifications to inform the application about scanner related events. This includes connectivity related events (i.e., appearance of a scanner), and scanner action events (i.e., received bar code data). All supported callbacks are defined by the ISbtSdkApiDelegate Objective-C protocol.

In order to receive asynchronous notifications from the SDK, the application performs the following steps:

1. Create an object that implements the ISbtSdkApiDelegate.

Code Snippet - Create A Class That Implements Isbtsdkapidelegate

// Definition of a class that implements the ISbtSdkApiDelegate protocol @interface EventReceiver : NSObject <ISbtSdkApiDelegate> {

// TODO: variables

}

// TODO: methods definition

2. Register the created object as notification receiver via the sbtSetDelegate function.

Code Snippet - Set Delegate Of API Instance To Object That Implements ISbtSdkApiDelegate

// Registration of the callback interface with SDK EventReceiver *eventListener = [[EventReceiver alloc] init];

[apiInstance sbtSetDelegate:eventListener];

SAMPLE SOURCE CODE 3 - 3

3. Subscribe for specific asynchronous events using the sbtSubscribeForEvents method to specify

which events should be reported by the SDK.

Valid notification/event mask values include:

• SBT_EVENT_BARCODE

• SBT_EVENT_IMAGE

• SBT_EVENT_VIDEO

• SBT_EVENT_SCANNER_APPEARANCE

• SBT_EVENT_SCANNER_DISAPPEARANCE

• SBT_EVENT_SESSION_ESTABLISHMENT

• SBT_EVENT_SESSION_TERMINATION

• SBT_EVENT_RAW_DATA.

Code Snippet - Subscribe To Scanner Events

// Subscribe to scanner appearance/disappearance, session establishment/termination, // barcode, and image & video event notifications. [apiInstance sbtSubsribeForEvents:SBT_EVENT_SCANNER_APPEARANCE | SBT_EVENT_SCANNER_DISAPPEARANCE | SBT_EVENT_SESSION_ESTABLISHMENT | SBT_EVENT_SESSION_TERMINATION | SBT_EVENT_BARCODE | SBT_EVENT_IMAGE | SBT_EVENT_VIDEO];

Events

If an object is registered as a notification receiver, the SDK calls the corresponding method of the registered object when a particular event occurs and the application is subscribed for events of this type.

Scanner Appeared Event

This event occurs when the presence of a scanner appears.

Code Snippet - Scanner Appeared Event

- (void)sbtEventScannerAppeared:(SbtScannerInfo*)availableScanner { // TODO: Handle event

}

Scanner Disappeared Event

This event occurs when a scanner is no longer present.

Code Snippet - Scanner Disappeared Event

- (void) sbtEventScannerDisappeared:(int)scannerID { // TODO: Handle event

}

3 - 4 Zebra Scanner SDK for iOS Developer Guide

Communication Session Established Event

This event occurs when communication is established with a scanner.

Code Snippet - Scanner Session Established Event

- (void)

sbtEventCommunicationSessionEstablished:(SbtScannerInfo*)activeScanner

{ // TODO: Handle event

}

Communication Session Terminated Event

This event occurs when communication with a scanner is terminated.

Code Snippet - Scanner Session Terminated Event

- (void) sbtEventCommunicationSessionTerminated:(int)scannerID { // TODO: Handle event

}

Bar Code Information Received Event

This event occurs when bar code data is read and received.

Code Snippet - Bar Code Data Received Event

- (void) sbtEventBarcodeData:(NSData *)barcodeData

barcodeType:(int)barcodeType fromScanner:(int)scannerID

{ // TODO: Handle event

}

Image Data Received Event

This event occurs when image data is received.

Code Snippet - Image Data Received Event

- (void) sbtEventImage:(NSData*)imageData fromScanner:(int)scannerID { // TODO: Handle event

}

Video Data Received Event

This event occurs when video data is received.

Code Snippet - Video Data Received Event

- (void) sbtEventVideo:(NSData*)videoFrame fromScanner:(int)scannerID { // TODO: Handle event

}
