IPhone JSON Array to Variables

Question

I have an array left over after parsing JSON that looks like ( -122.1407313, 37.7012704, 0 ) , How do I put them seperately into variables without an object or index to call? I tried:

NSArray *coordinates = [point objectForKey:@"coordinates"]; //holds the array above
NSString *lat = [coordinates objectAtIndex:0];
NSString *lon = [coordinates objectAtIndex:1];

What JSON parser are you using? If you got numbers in your JSON you might as well have NSNumber objects instead of NSStrings. What are the error messages? — Dennis Bliefernicht

Its SBJson, yeah, I should be using NSNumber, would this have an effect on it? No error messages. — savagenoob

I lied, its giving an uncaught exception: *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '*** -[NSDecimalNumber length]: unrecognized selector sent to instance 0x47eeb50' — savagenoob

You want something like:

NSNumber *lat = (NSNumber*)[coordinates objectAtIndex:0];
float latValue = [lat floatValue];
