VENExperimentsManager

Build Status

VENExperimentsManager enables easy definition, management and control of experiments within an iOS app including the following:

  • Define experiments and ‘experiment flag’ code
  • Allow users to turn experiments on and off
  • Force turn-on or off experiments
  • Make experiments user-editable or fixed
  • Let users know whether experiments are ‘stable’ or ‘unstable’

VENExperimentsManager

Usage

[VENExperimentsManager startExperimentsManagerWithPlistName:@"testExperiments"];

Then you can access experiments as follows..

VENExperiment *experiment = [VENExperimentsManager experimentWithIdentifier:VEN_EXPERIMENT_SOME_EXPERIMENT];

// Or if you just want to know if it's enabled
[VENExperimentsManager experimentIsEnabled:VEN_EXPERIMENT_SOME_EXPERIMENT];

Multi-option experiments (new in v0.2.0) can be used as follows..

NSString *selectedOptionForExperiment = [VENExperimentsManager selectedOptionForExperiment:VEN_EXPERIMENT_SOME_EXPERIMENT];

// Or you can get the experiment and inspect it..
VENExperiment *experiment = [VENExperimentsManager experimentWithIdentifier:VEN_EXPERIMENT_SOME_EXPERIMENT];

// Determine if the experiment has options
BOOL hasOptions = [experiment supportsOptions];

// Get the selected option
NSString *selectedOption = [experiment selectedOption];

// Get the readable description of the selected option
[experiment selectedOptionDescription];

The plist file defining experiments is a dictionary of experiment-identifier : experiment-definition dictionaries. It can be easily configured in XCode.

VENExperimentsManager

A sample experiments.plist file can be found in the Sample Application.

Key descriptions

VEN_EXPERIMENT_NAME : String – The name of the experiment as it will appear in the Settings view

VEN_EXPERIMENT_STABLE : Boolean – Whether the experiment is stable or not (grouped in Settings view)

VEN_EXPERIMENT_ENABLED : Boolean – The default enabled state for the experiment

VEN_EXPERIMENT_USER_EDITABLE : Boolean – Whether the user can change the state of the experiment

VEN_EXPERIMENT_FORCE_UPDATE : Boolean – If this is YES, the experiment will be force-moved to it’s default state every open.

VEN_EXPERIMENT_OPTIONS : Dictionary – Key-Value pairs of KEY : Readable description for options for this experiment.

VEN_EXPERIMENT_DEFAULT_OPTION: String – The key of the default option in the dictionary of options

Experiment Settings View Controller

The library also contains a basic Experiment Settings View Controller which you can present to allow users to enable and disable experiments.

#import "VENExperimentsSettingsTVC.h"

...

VENExperimentsSettingsTVC *settingsTVC = [[VENExperimentsSettingsTVC alloc] init];
[self.navigationController pushViewController:settingsTVC animated:YES];

This will give an Experiment Settings screen that looks like this…
