Track which versions of your iOS or Mac OS X app a user has previously installed.
Call this on each app launch inside application:didFinishLaunching:withOptions: (iOS), or -applicationDidFinishLaunching: (OS X)
[GBVersionTracking track];Then call these whenever you want (in these examples the user has launched a bunch of previous versions, and this is the first time he's launched the new version which is version 3.0):
[GBVersionTracking isFirstLaunchEver]; //Returns: NO
[GBVersionTracking isFirstLaunchForVersion]; //Returns: YES
[GBVersionTracking isFirstLaunchForBuild]; //Returns: YES
[GBVersionTracking currentVersion]; //Returns: @"3.0"
[GBVersionTracking previousVersion]; //Returns: @"2.1"
[GBVersionTracking firstInstalledVersion]; //Returns: @"1.0"
[GBVersionTracking versionHistory]; //Returns: [@"1.0", @"2.0", @"2.1", @"3.0"]
[GBVersionTracking currentBuild]; //Returns: @"3004"
[GBVersionTracking previousBuild]; //Returns: @"2107"
[GBVersionTracking firstInstalledBuild]; //Returns: @"1000"
[GBVersionTracking buildHistory]; //Returns: [@"1000", @"2043", @"2107", @"3004"]N.B.: The build and version numbers are whatever you define in your app's Info.plist
Don't forget to import header:
#import <GBVersionTracking/GBVersionTracking.h>Use CocoaPods, add this to your project's Podfile and run pod install:
pod 'GBVersionTracking'
