auto-lock iphone/ipad programmatically

问题

Is there a way to 'force' the user to have auto-lock (and maybe passcode lock) on while the application is running (for security reasons mainly)? If we can't set them programmatically, can we at least check to see if they are set?

Thanks, Mihai

回答1:

if ([UIApplication sharedApplication].idleTimerDisabled == YES) {
    UIAlertView *alert = [[UIAlertView alloc]initWithTitle:@"Please enable auto-lock"...];
    [alert show];
    [alert release];
} else {
    /* some code */
}

The above snippet will check to see if the idle timer is disabled. If it is, it will tell the user to enable it via a UIAlertView.

YOu can use a Session handler class which inherits from UIApplication and fix a timer.. Thats very easy and fully customizable.
