Second object of each pair must be non-nil

Question

Iam working on app and when i debug my code it is showing the following error.

-(IBAction)addSelected:(id)sender
{

    NSString* emptyStr = @\"\";

    NSDictio         


        

Answer 1

In my case i was doing this:

NSDate *today = [NSDate date];
    NSTimeInterval currentTime = [today timeIntervalSince1970];

    NSMutableDictionary *dictExpiryDate =
    [NSMutableDictionary dictionaryWithObjectsAndKeys:currentTime, KEY_4_VALUE_OF_EXPIRY_DATE, nil];

The problem here is currentTime, i replaced currentTime as followed:

[NSNumber numberWithDouble:currentTime]

This solved my issues.
