Answer 1

NSMutableArray *testArray=[[NSMutableArray alloc] initWithObjects:@"A",@"B",@"C", nil];
[testArray removeObjectsInRange:NSMakeRange(1, testArray.count-1)];

But please make sure array count is greater than 1.

Try this one and put your range to remove your object.

[array removeObjectsInRange:NSMakeRange(1, array.count-1)];

Keep a reference to your a object (MyObject temp = [array objectAtIndex:0]), do removeAllObjects, then insertObject:a
