Problem with BOOL and NSUserDefaults

[letmusicring]

I am trying to get my app to determine, upon launch, if the timer was running when the app quit (or went inactive). Here is my code:

View.m (defaults is [NSUserDefaults standardUserDefaults] and timerIsRunning is declared as "bool timerIsRunning" in the .h)

- (IBAction)clockIn:(id)sender {
	if (timerIsRunning == NO) {
        mainInt = [defaults floatForKey:@"wageIsPause"];
        randomMain = [NSTimer scheduledTimerWithTimeInterval:(0.1/1.0) target:self selector:@selector(randomMainVoid) userInfo:nil repeats:YES];
        timerIsRunning = YES;
        [defaults setBool:timerIsRunning forKey:@"timerRun"];
        [defaults synchronize];

In my delegate.m file

- (void)applicationDidBecomeActive:(UIApplication *)application {
NSUserDefaults *defaultsOpen = [NSUserDefaults standardUserDefaults];
    [defaultsOpen synchronize];
    bool timerIsRunning = [defaultsOpen boolForKey:@"timerRun"];
    
    if (timerIsRunning == NO) {
        NSLog(@"Timer is not running.");
    }
    else {
        NSLog(@"Timer is running.");
    }
}

The problem is that when I open my app and the timer is running, it logs "Timer is not running." It also logs "Timer is not running." when the timer isn't running (which was to be expected.) I am getting no errors or warnings.

What am I missing here?

1. I don't see 'defaults' declared in 'clockIn:' method
2. What's the point of this calculation: 0.1/1.0 ?
3. You don't need to synchronize defaults before reading.
4. When you open the app, it will not log wether the timer is actually running or not but what is stored in user defaults. You need to restart the timer yourself.

1. defaults is declared in view.h as [NSUserDefaults standardUserDefaults];
2. it's makes the timer run 10x as needed by the app.
3. Good to know, thanks.
4. The bool is set to YES in the 'clockIn:' method and saved to user defaults. Therefore, shouldn't the delegate be able to read the bool from user defaults and tell me whether it is set to YES or NO? It says NO even after it was set to YES.

You mean you made it as a macro in the header file? If it's not properly set then that's why nothing is being recorded if 'defaults' is nil. Try putting this in your IBAction and check the output

NSLog(@"defaults = %@", defaults);

That was my problem, got it working. Thanks!
