Is this expected?
NSMutableIndexSet *someIndexes = [NSMutableIndexSet indexSet];
[someIndexes addIndex:0];
[someIndexes addIndex:2];
[someIndexes shiftIndexesStartingAtIndex:2 by:-1];
BOOL result1 = [someIndexes containsIndex:0];
BOOL result2 = [someIndexes containsIndex:1];
BOOL result3 = [someIndexes containsIndexesInRange:NSMakeRange(0,2)];
Here is the error. You are asking if the index set contains (0,1,2),
But it only contains (0, 1) after the shift
Try using NSMakeRange (0,1) instead.
But NSMakeRange takes (index, length) not ( start index, end index )
so the original post seems correct.
