Question

I have a NSTimeInterval and I have a JSON value 1257808000000.

I do this:

 NSTimeInterval *myTimestamp = [myJSON objectForKey:@"thetimestamp"];

But I get this warning:

Incompatible pointer types initializing 'NSTimeInterval *' (aka 'double *') 
with an expression of type 'id'

How can I solve this problem?

Best Regards.

NSTimeInterval is actually a double value. It’s not an object.

NSTimeInterval myTimestamp = [[myJSON objectForKey:@"thetimestamp"] doubleValue];
