How do I increment a NSNumber?
Update: FYI, I personally like BoltClock's and DarkDusts's one-line answers better. They're more concise, and don't require additional variables.
In order to increment an
NSNumber, you're going to have to get its value, increment that, and store it in a new
For instance, for an
NSNumber holding an integer:
NSNumber *number = [NSNumber numberWithInt:...]; int value = [number intValue]; number = [NSNumber numberWithInt:value + 1];
Or for an
NSNumber holding a floating-point number:
NSNumber *number = [NSNumber numberWithDouble:...]; double value = [number doubleValue]; number = [NSNumber numberWithDouble:value + 1.0];
