ApptimizeVariable

@interface ApptimizeVariable : NSObject

This interface is used to create and retrieve dynamic variables for both experiments and Feature Variables.

The factory methods are used to create and register dynamic variables with the SDK. As they need to be declared prior to setting up an experiment, they should be called as early as possible during app execution, such as in didFinishLaunchingWithOptions.

All the factory methods return a reference to the created dynamic variable.

As dynamic variables are expected to be declared ahead of time during app startup, getters are provided to retrieve those dynamic variables at time of use.

Factory methods

  • Create a string dynamic variable with a specified name and default value.

    See

    +[ApptimizeVariable getStringForName:]

    Declaration

    Objective-C

    + (ApptimizeVariableString *_Nullable)stringWithName:(NSString *_Nonnull)name
                                    andDefaultString:
