Presenting view controller memory leak

[reggian]

The Wootric SDK stores the presenting view controller in a strong static reference and never releases it.

Stored in show survey method:

WootricSDK-iOS/WootricSDK/WootricSDK/Wootric.m

Lines 292 to 313 in a6418c8

	+ (void)showSurveyInViewController:(UIViewController *)viewController {
	WTRSurvey *surveyClient = [WTRSurvey sharedInstance];
	if ([surveyClient checkConfiguration]) {
	[surveyClient survey:^(WTRSettings *settings){
	[WTRLogger log:@"presenting survey view"];
	_presentedViewController = viewController;
	_presentedSettings = settings;
	dispatch_async(dispatch_get_main_queue(), ^{
	[self performSelector:@selector(presentSurveyInViewController:)
	withObject:@[viewController, settings]
	afterDelay:settings.timeDelay];
	[[[WTRDefaultNotificationCenter alloc] initWithNotificationCenter:[NSNotificationCenter defaultCenter]] postNotificationName:[Wootric surveyWillAppearNotification] object:self];
	[[Wootric delegate] willPresentSurvey];
	});
	}];
	} else {
	[WTRLogger log:@"Configure SDK first"];
	}
	}

Static variables:

WootricSDK-iOS/WootricSDK/WootricSDK/Wootric.m

Lines 35 to 37 in a6418c8

	static id<WTRSurveyDelegate> _delegate = nil;
	static UIViewController *_presentedViewController;
	static WTRSettings *_presentedSettings;
