macOS NSDictionary and NSUserNotification Question

DavidBlack said:

Hi, guys I am almost done building this app I am making but I have this problem, I looked online on how to get a random keys and values from a NSDictionary it works fine also I have NSUserNotification to get the values from the NSDictionary and give the user a text/quotation. Here is my code:

Code:

-(void)friendshipTimer:(NSTimer *)friendshipTimer {
    NSLog(@"NSUserNotificationCenter fired");
  
    // refer to this for more help :http://www.renssies.nl/2012/02/mountain-lion-the-new-notifications-center/
    NSBundle* bundle = [NSBundle mainBundle];
    NSString* plistPath = [bundle pathForResource:@"friendshipKeys" ofType:@"plist"];
    NSDictionary* plisttext = [NSDictionary dictionaryWithContentsOfFile:plistPath];
    //Now to generate and display random sentences, you would need to keep a track of all the keys:
    
    NSArray* keys = [plisttext allValues];
    //Then select a random key using the index:
    
    int randomIndex = arc4random() % (keys.count);
    NSString* key = [keys objectAtIndex:randomIndex];
    
    //Initalize new notification
    NSUserNotification *notification = [[NSUserNotification alloc] init];
    //Set the title of the notification
    [notification setTitle:@"My Title"];
    //Set the text of the notification
    [notification setInformativeText:[NSString stringWithFormat:@"%@",key]];
    //Set the sound, this can be either nil for no sound, NSUserNotificationDefaultSoundName for the default sound (tri-tone) and a string of a .caf file that is in the bundle (filname and extension)
    [notification setSoundName:NSUserNotificationDefaultSoundName];
    
    //Get the default notification center
    NSUserNotificationCenter *center = [NSUserNotificationCenter defaultUserNotificationCenter];
    //Scheldule our NSUserNotification
    [center scheduleNotification:notification];



}

But when the notification comes up more that one text/quotation comes up at the same time and overlap each other. Can anyone help?

Code:

            NSDate *d = [NSDate dateWithTimeIntervalSinceNow:myInt2];
            timerFriendTimer = [[NSTimer alloc] initWithFireDate: d
                                                  interval: myInt2
                                                    target: self
                                                  selector:@selector (friendshipTimer:)
                                                userInfo:nil repeats:YES];

It's a timer in

Code:

- (void)userdefaultsKey1or2Changed:(NSString *)keyPath ofObject:(id)target change:(NSDictionary *)change userInfo:(id)userInfo {}

It just detects changes in the NSUserDefaults

My myInt2 is an NSInteger. I am just taking the value of the textbox and getting it's integerValue example if I place the number on in the text box. And then multiply it by 60 convert it to minutes.

myInt2 = [stringTextBoxTabSuccess integerValue] * 60;

I also have a NSLog to know that is the value just to make sure.

Code:

    NSLog(@"string value is %ld",(long)myInt2);

NSTimeInterval
Used to specify a time interval, in seconds.

typedef double NSTimeInterval;
Discussion
NSTimeInterval is always specified in seconds; it yields sub-millisecond precision over a range of 10,000 years.

myInt2 = [stringTextBoxTabSuccess integerValue] * 3600;

repeats:YES

            timerFriendTimer = [[NSTimer alloc] initWithFireDate: d
                                                  interval: myInt2
                                                    target: self
                                                  selector:@selector (friendshipTimer:)
                                                userInfo:nil repeats:[B][COLOR="Red"]NO[/COLOR][/B]];

He's using NSUserNotificationCenter, a separate and very different class from NSNotificationCenter that was introduced in Mountain Lion.
