Apptimize

@interface Apptimize : NSObject

The Apptimize interface is the main interaction point with the Apptimize SDK for developers.

Getting Started

Add your Apptimize App Key to your application’s Info.plist e.g.

 ApptimizeAppKey = "AaaaABbbbBCcccCDdddDEeeeEFfffF" // Type: String; Without quotes.

For more information on how to get started using the Apptimize Library see: http://apptimize.com/docs/getting-started-ios/step-1-installation-ios/

    When this method is called, one of the code block variants or the default code block will be run sychronously in accordance with the A/B test variant this user/device is enrolled in.

    Declaration

    Objective-C

    + (void)runTest:(NSString *)testName
        withBaseline:(void (^)(void))baselineBlock
          variations:(NSDictionary *)variations
          andOptions:(NSDictionary *)options;

    variations

    A dictionary containing code blocks keyed using strings. The string keys must match the name of the variant set in the Apptimize dashboard.

    options

    Nil or a dictionary containing ApptimizeUpdateMetadataTimeoutOption and a value in milliseconds.

  • Run a code block A/B test.

    This is the same as calling +[Apptimize runTest:withBaseline:variations:andOptions:] with nil for options.

    When this method is called, one of the code block variants or the default code block will be run sychronously in accordance with the A/B test variant this user/device is enrolled in.

    Declaration

  • Force a variant with a given ID to be enabled.

    Once forceVariant is called, Apptimize is placed in a special test mode where it will only enable variants that are forced by forceVariant. All other Feature Flags, A/B Experiments and Instant Updates will appear disabled/off unless a specific variant is forced for those projects. Call forceVariant for each of the variants you want to apply.

    See

    +[Apptimize clearAllForcedVariants] to return Apptimize to normal operation.

    All variants forced using this method will be treated as though they underwent experiment selection, and will be reflected on your results dashboard. Forced variants are persistent across application launches and will not be reset except by calls to +clearForcedVariant:variantID: or +clearAllForcedVariants:.

    Note: the Advanced Verify feature on the dashboard will not work when there are forced variant(s) on the paired device. This is because Advanced Verify works by sending an instant update to the paired device.

    Declaration

    Objective-C

    + (void)forceVariant:(NSInteger)variantID;

    Swift

    class func forceVariant(_ variantID: Int)

    Parameters

    variantID

    The numeric ID of the variant to forcibly enable.
