Hide backgrounding in iOS

	While analyzing the source code, look for the fields or screens where sensitive data is involved. Identify if the application sanitize the screen before being backgrounded by using UIImageView.

	Possible remediation method that will set a default screenshot:

	@property (UIImageView *)backgroundImage;

	- (void)applicationDidEnterBackground:(UIApplication *)application {
	UIImageView *myBanner = [[UIImageView alloc] initWithImage:@"overlayImage.png"];
	self.backgroundImage = myBanner;
	[self.window addSubview:myBanner];
