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.

Answer 1

Try this:

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