iPhone - phone goes to sleep even if idleTimerDisabled is YES

Question

I am using this in my appdelegate\'s applicationDidFinishLaunching: method to make sure the iPhone doesn\'t go to sleep during the time the app is open

[appl         


        

Answer 1

I think the setIdleTimerDisabled doesn't exist in UIApplication class. Property searches not only set- method but also other similar named methods.

Use dot accessor is the best way to solve your problem.

Answer 2

i had the same problem. i need to make the screen dim, but when turn off the camera, the iphone goes to sleep.

- (void)viewWillAppear:(BOOL)animated {
    [super viewWillAppear:animated];
    [[UIApplication sharedApplication] setIdleTimerDisabled:YES];
}

- (void)viewWillDisappear:(BOOL)animated {
    [super viewWillDisappear:animated];
    [[UIApplication sharedApplication] setIdleTimerDisabled:NO];
}

Then i call it after turn on/off the camera, it works.

[[UIApplication sharedApplication] setIdleTimerDisabled:YES];

Answer 3

I set and un-set this property throughout my app using:

[UIApplication sharedApplication].idleTimerDisabled = YES;

Setting this where you're having trouble could fix it, though it might be a bit of a band-aid solution.
