Can we lock the app while app goes to sleep mode in IPhone?

Question

I am working an app where lock option is included.My app starts with passcode screen.If I enter correct code then it navigates to next screen.If I dont use the app for long time

Answer 1

I have developed same type of apps, where I have implemented this things, For this I made a one Class like this

@interface CommonUIClass:NSObject

+(void)setCurrentViewController:(id)controller;

+(void)openPassWordProtectedScreen;

@end

And

@implementation CommonUIClass

static id currentViewControllerObj;

+(void)setCurrentViewController:(id)controller{ 

  currentViewControllerObj = controller;

}

+(void)openPassWordProtectedScreen{

PROTECTED_CONTROLLER *view = [[PROTECTED_CONTROLLER alloc]init];



if ([currentViewControllerObj respondsToSelector:@selector(presentModalViewController:animated:)]) {
        [currentViewControllerObj presentModalViewController:patternLock animated:NO];
}

}


@end

Just import this class to every ViewController And put this code to

-(void)viewWillApear{

[CommonUIClass setCurrentViewController:self];
[super viewWillApear];
}

And When Application Goes in Background

-(void)applicationWillResignActive:(UIApplication *)application{

[CommonUIClass openPassWordProtectedScreen];

}

Thanks..
