iOS: Objectifying MKCoordinateSpan to put in an array

Question

Im trying to find a direct way to put MKCoordinateSpan into an array without breaking it down to lat and long and store it in an NSArray. Not sure if there is such way.

MKCoordinateSpan span = MKCoordinateSpanMake(1.0, 1.0);
NSData *data = [NSData dataWithBytes:&span length:sizeof(span)];

MKCoordinateSpan back;
[data getBytes:&back length:sizeof(back)];

NSLog(@"%f",back.latitudeDelta);

pretty much the same approach as below I guess? +1 for the effort :) – Byte Jul 24 '12 at 17:03

Try this:

MKCoordinateSpan currentSpan;
currentSpan = ...; // Set the span to somethinf
NSValue *spanVal = [NSValue valueWithBytes:&currentSpan objCType:@encode(MKCoordinateSpan)];
...
MKCoordinateSpan currentSpanBack;
[spanVal getValue:&currentSpanBack];

I never tried this myself, but I've seen examples that suggest that it might work. – Sergey Kalinichenko Jul 24 '12 at 14:43
