Add an array value to another array

Question

How can I add an array value to another array?

I get the array using:

NSMutableArray *pointsArray = [[result componentsSeparatedByCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet]] retain];

I want to add the first and the last value of pointsArray to another array.

do you want to append values in existent array?

[array addObject:[pointsArray objectAtIndex:0]]; //First Object
[array addObject:[pointsArray lastObject]]; //Last Object

But this array should be an NSMutableArray.

as follows

NSUInteger totObjects = [pointsArray count];
[yourOtherArray addObject:[pointsArray objectAtIndex:0]]; //First Object
[yourOtherArray addObject:[pointsArray objectAtIndex:totObjects-1]]; //Last Object

@Shima you mean to say yourOtherArray already has few objects in that ? and you want to get first and last value of that also ?

pointsArray = [[result componentsSeparatedByCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet]] retain]; NSInteger totobjects = [pointsArray count]; [annArray addObject:[pointsArray objectAtIndex:0]]; [annArray addObject:[pointsArray lastObject]]; NSLog(@"This fro thr %@",[annArray objectAtIndex:0]);

Its simple just add like this

NSArray *otherArray = [[NSArray alloc] initWithObjects: [pointsArray objectAtIndex:0], [pointsArray objectAtIndex:[pointsArray count]-1],nil];

This can be achieved by using this:

NSMutableArray *recentPhotos = [[NSMutableArray alloc] init];

//add one object to the array
[recentPhotos addObject: selectPhotos];
