I have a NSMutableArray called putNumberUsed. It contains the following objects @"blah1,@"blah2",@"blah3",@"blah4". I want to shuffle these objects randomly so for example if I chose:
[putNumberUsed objectAtIndex:0]
it would give me anything but "blah1". How would I go about doing this? The following is the code I used thus far:
NSMutableArray *putNumbersUsed = [[NSMutableArray alloc] arrayWithObjects:@"blah1",@"blah2",@"blah3",@"blah4",nil];
I think, You can write a loop for that. Please check the following code,
for (int i = 0; i < putNumberUsed.count; i++) {
int randomInt1 = arc4random() % [putNumberUsed count];
int randomInt2 = arc4random() % [putNumberUsed count];
[putNumberUsed exchangeObjectAtIndex:randomInt1 withObjectAtIndex:randomInt2];
}
I this this may be useful to you.
