NSArray with values

Question

How can I create an NSArray with values populated?

That is to say:

NSArray *name=[NSArray alloc];
// insert these values: raju, biju.ramu

Solution 1

Use the NSArray initWithObjects method, remembering to put nil in as the last value:

NSArray *names = [[NSArray alloc] initWithObjects:@"raju", @"biju", @"ramu", nil];

Solution 2

If you need to modify an existing array, You must use NSMutableArray

NSMutableArray *name=[[NSMutableArray alloc]init]; 
[name addObject: @"raju"];
[name addObject: @"biju"];

Solution 3

NSMutableArray *name=[[NSMutableArray alloc]init];
for(int i=0;i<=10;i++)
{

    NSString *nm=[NSString stringWithFormat:@"Raju %d",i];
    [name addObject:nm];

}

If he indeed wants to modify an existing array, you should use this as declaration; NSArray *name_array = [[NSArray alloc] init]; // array stuff NSMutableArray *names = [[NSMutableArray alloc] initWithArray:name_array]; [names addObject: @"raju"]; [names addObject: @"biju"];

Alternatively, you can just use [array mutableCopy] instead of the alloc+initWithArray approach.

You forgot to -init your name array and you’re trying to mutate a non-mutable type. -addObject: is an NSMutableArray method.
