This library allows you to instrument your code with operational and behavioral metrics/analytics in your iOS application.

Import the library:

Objective-C:

Add the header in your AppDelegate class

#import "AppAnalyticsHubiOS.h"

Swift

Add this header to the Bridging header

#import <AppAnalyticsHubiOS/AppAnalyticsHubiOS.h>

AppAnalyticsHub is a singleton class which you can access as AppAnalyticsHub.shared.

Objective-C

AppAnalyticsHub * appAnalyticsHub = AppAnalyticsHub.shared;

Swift

let appAnalyticsHub = AppAnalyticsHub.shared

In App Analytics Hub, to record your events in different Analytic systems you would have to register different implementations of AnalyticsCollector to a specific AppAnalyticsHubEventType in AppAnalyticsHub. The AnalyticsCollector implementations will be responsible for understanding the App Analytics Hub Event and create the respective Analytics system events. For example, if you want all your user engagement events be registered in AWS Pinpoint you would register the AWSPinpointAnalyticsCollector to the engagement event type and whenever an event with type user engagement is record in AppAnalyticsHub the AWSPinpointAnalyticsCollector would be triggered to record the event in AWSPinpoint.

Set a default metrics collector(optional):

Objective-C

[appAnalyticsHub setDefaultCollector:defaultCollector]

Swift

appAnalyticsHub.defaultCollector = DefaultCollector()

Register a collector:

Objective-C

[appAnalyticsHub registerCollector: testCollector];

Swift

appAnalyticsHub.register(testCollector)

Add a collector to an EventType:

Objective-C

[appAnalyticsHub addCollector:metricsCollector toEventType:AppAnalyticsHubEventTypeEngagement]

Swift

appAnalyticsHub.add(testCollector, toEventType: EventType.engagement)

Remove a collector from an EventType:

Objective-C

[appAnalyticsHub removeCollector:metricsCollector fromEventType:AppAnalyticsHubEventTypeEngagement]

Swift

appAnalyticsHub.remove(testCollector, toEventType: EventType.engagement)

Create a custom collector (if required):

Objective-C

@implementation TestCollector: NSObject, MetricsCollector {
	var name: String = "test collector";
}
- (void)record:(Event) event {
	NSStirng * logString = [NSString stringWithFormat:@"Event Name = %@,  Event Source = %@", event.name, event.source];
	print(@"%@", logString);
}
@end

Swift

class TestCollector: NSObject, MetricsCollector {
	var name: String = "test collector"
	
	func record(_ event: Event) {
		print("Event Name = ", event.name, "Event Source = ", event.source)
	}
}

Creation of event:

Objective-C

AppAnalyticsHubEvent * event = [[AppAnalyticsHubEvent alloc]initWithName:@"AuthSuccess"
                                                                  source:@"Authentication" //source is optional
                                                                    type:AppAnalyticsHubEventTypeOperational
                                                                 priority:AppAnalyticsHubEventPriorityHigh // priority is optional, default to Normal
                                                                    ];

Swift

let event = Event(name: "AuthSuccess",
                source: "Authentication", //source is optional
                  type: EventType.operational,
              priority: EventPriority.high) // priority is optional, default to Normal

An Event should consists of name and an event type.

An Event-type can be a string or an EventType enum. The default event-types provided by App Analytics hub are:

• ENGAGEMENT : All the user engagement event can be linked with ENGAGEMENT event-type.
• OPERATIONAL : All the events related to your operational metrics can be linked with OPERATIONAL event-type.

Events can consists of multiple counter, timers, metrics and data.

Data associated to an event is stored as a map of string to string key value pairs and recording data can be done by simply calling the addData method of an event.

Objective-C

[event addData:@"value" forKey:@"dataKey"];
[event addData:@"value1" forKey:@"dataKey1"];

Swift

event.addData("value", forKey: "dataKey")
event.addData("value1", forKey: "dataKey1")

Counters associated to an event are stored as a map of string to number key value pairs. Counter can be added, incremented and also removed from an event.

Objective-C

// adding a counter
[event addCounterForKey:@"counter"]; // the default value of 1 is used if the value is not provided.
or
[event addCounterForKey:@"counter" initialCount:@2];
            
// incrementing a counter
[event incrementCounterForKey:@"counter"]
or 
[event incrementCounterForKey:@"counter" by:@3];
        
// removing 
[event removeCounterForKey:@"counter"];

Swift

// adding a counter
event.addCounter(forKey: "counter") // the default value of 1 is used if the value is not provided.
or
event.addCounter(forKey: "counter", initialCount: 2)
        
// incrementing a counter
event.incrementCounter(forKey: "counter")
or 
event.incrementCounter(forKey: "counter", by: 3)
        
// removing 
event.removeCounter(forKey: "counter")

Metrics associated to an event are stored as a map of string to string or boolean key value pairs. Metrics can be added and removed for any type of value but can only be incremented if the value is a number.

Objective-C

// adding a metric
[event addMetric:@"value" forKey: @"string metric"];
[event addMetric:@true forKey: @"boolean metric"];
        
// removing a counter
[event removeMetricForKey: @"string metric"];

Swift

// adding a metric
event.addMetric("value", forKey: "string metric")
event.addMetric(true, forKey: "boolean metric")
        
// removing a counter
event.removeMetric(forKey: "string metric")

Timers associated to an event are stored as a map of string to number key value pairs. Timers can be added, incremented and also removed from an event.

Objective c

// adding a timer
[event addTimerForKey: @"timer" timeElapsed: @100.0];
    
// incrementing a timer. Timers don"t have a default value.
[event incrementTimerForKey: @"timer" by: @200.0];
    
// removing a timer
[event removeTimerForKey: @"timer"];

Swift

// adding a timer
event.addTimer(forKey: "timer", timeElapsed: 100.0)
    
// incrementing a timer. Timers don"t have a default value.
event.incrementTimer(forKey: "timer", by: 200.0)
    
// removing a timer
event.removeTimer(forKey: "timer")

TimersMetric are objects that you can use to conveniently measure duration in your application. Like a stop watch, they support two operations: start and stop. Once you have measured a duration in your application using a TimerMetric object, you can use the recordTimer and recordTimerInEvents operations to record it to one or many events, depending on your use-case.

Objective c

AnalyticsHubTimerMetric * timerMetric = [[AnalyticsHubTimerMetric alloc]initWithName:@"timermetric" parent:event]; // providing a parent event is optional but is advised.
// start your timer
[timerMetric start];
    
// stop your timer
[timerMetric stop];
    
// the above methods can be called multiple times and the everytime you stop a timer, time is aggregated to total time.
    
// record the timer to the parentEvent
[timerMetric record];
    
// record the timer to other events
//pass in all the events you want this timer to get recorded.
[timerMetric recordInEvents:event1, event2, event3];

Swift

let timer = TimerMetric(name: "timermetric", parent: event) // providing a parent event is optional but is advised.
// start your timer
timer.start()
// stop your timer
timer.stop()
    
// the above methods can be called multiple times and the everytime you stop a timer, time is aggregated to total time.
    
// record the timer to the parentEvent
timer.record()
    
// record the timer to other events
//pass in all the events you want this timer to get recorded.
timer.record(in: [event1,event2,event3])

Record an event:

Objective-C

[appAnalyticsHub recordEvent:event]

Swift

appAnalyticsHub.record(event)
