How to store NSTimeInterval values into a NSMutableArray?

Solution
But everytime after the click of good button i am getting the Array count as only 1.
This is not surprising, considering that you are creating a brand-new `NSMutableArray` on the previous line.
To fix this, you need to make `NSMutableArray *arrayContainsGoodClicks` an instance variable (AKA ivar), initialize it to `[NSMutableArray array]` in your designated initializer, and then use
[arrayContainsGoodClicks addObject:goodTimeIntervals];
to add objects to the array.
If you are looking to use `NSMutableDictionary` instead, the strategy would be identical, except you would need to decide on an object that you would like to use as unique keys to your `NSDictionary`. Also remember that `NSMutableDictionary` is not ordered, so you might need to take care of sorting each time you display your dictionary items to users.
Problem
I have a requirement where i have a Video that is played using `MPMediaPlayerController`. Along with the video i have two buttons where i need to capture the current playback time when the button are clicked and store all the relevant clicks individually. I am able to get the current playback time of the video using "currentPlaybackTime" property which returns `NSTimeInterval`. But can someone help me in how to store all the `NSTimeInterval` values into an `NSMutableDictionary`. I have tried the following ways: ``` -(void)onClickOfGood { NSLog(@"The current playback time in good:%g",moviePlayerController.currentPlaybackTime); currentPlaybackTime = moviePlayerController.currentPlaybackTime; //NSArray *arrayContainsGoodClicks = [[NSArray alloc]initWithObjects:currentPlaybackTime, nil ]; NSNumber *goodTimeIntervals = [NSNumber numberWithDouble:currentPlaybackTime]; NSMutableArray *arrayContainsGoodClicks = [[NSMutableArray alloc]initWithObjects:goodTimeIntervals,nil ]; NSLog(@"The total count of Array is: %i",[arrayContainsGoodClicks count]);} ``` But everytime after the click of good button i am getting the Array count as only 1. Can someone please throw a light on where i am going wrong?
