So you want to swap contents of both arrays? Or just send all of arrayone's contents to arraytwo, and release arrayone? Sorry, I'm just a little confused about your intentions.avizzini– avizzini2011-05-19 14:02:42 +00:00Commented May 19, 2011 at 14:02

4Use the removeAllObjects: method on arrayone, then [arrayone addObjectsFromArray:arraytwo].avizzini– avizzini2011-05-19 14:08:10 +00:00Commented May 19, 2011 at 14:08

Lets say you have:
NSMutableArray *arrayOne = [[NSMutableArray alloc]initWithObjects:@"A", @"B",nil ];
NSMutableArray *arrayTwo = [[NSMutableArray alloc]initWithObjects:@"C", @"D",nil ];
Now you can remove all objects and insert the new objects like this:
[arrayOne removeAllObjects];
[arrayOne addObjectsFromArray:arrayTwo];
Or release the array and initialize a new one like this:
[arrayOne release];
arrayOne = [[NSMutableArray alloc] initWithArray:arrayTwo];
In both cases NSLog(@"%@",arrayOne); shows:
(
C,
D
)
Comments
arrayOne = [[NSMutableArray alloc] initWithArray:arrayTwo copyitems:YES];
