You can use the FoneMonkey API to create a script. Use the FoneMonkeyAPI static playCommands method to add commands to the current script.

/**
 Play the supplied array of FMCommandEvents.
 @return nil if all comamnds run successfully and an error or failure message otherwise.
 */
+ (NSString*) playCommands:(NSArray*)commands;

You can create an FMCommandEvent with following FMCommandEvent static method.

/**
 Create a new FMCommandEvent
*/
+ (FMCommandEvent*) command:(NSString*)cmd className:(NSString*)name monkeyID:(NSString*)id args:(NSArray*)array;

Example

- (void) testSomething {
    NSMutableArray* array = [NSMutableArray array];
    [array addObject:[FMCommandEvent command:@"Touch" className:@"UITabBarButton" monkeyID:@"GLPaint" args:nil]];
    NSString* lastResult = [FoneMonkeyAPI playCommands:array];
    STAssertNil(lastResult, lastResult);   
}
