Any one Please help me out to solve this issue

Answer 1

I'm answering to consider that this is an Simple NSArray -

Your array is like this -

 NSArray *array = @[@[@"2013-06-15 02:00"], @[@"2013-06-16 02:00"], @[@"2013-06-18 02:00"], @[@"2013-06-19 02:00"], @[@"2013-06-19 02:00"]];
 NSLog(@"\n%@",array);

And then output of this array is:-

( ( "2013-06-15 02:00" ), ( "2013-06-16 02:00" ), ( "2013-06-18 02:00" ), ( "2013-06-19 02:00" ), ( "2013-06-19 02:00" ) )

Now lets filter this array -

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

for(int i=0; i<[array count]; i++)
{
    [newArray addObject:array[i][0]];
}

NSLog(@"\n%@", newArray);

Output is:- ( "2013-06-15 02:00", "2013-06-16 02:00", "2013-06-18 02:00", "2013-06-19 02:00", "2013-06-19 02:00" )

Answer 2

Use objectAtIndex as below:

[yourArray objectAtIndex:i]

where i represents index,if you want first string then use 0,second then 1,....etc.

Hope this might help you.

Since I'm in a canihazecode-mood:

NSArray *array = ...
NSMutableArray *cleanedArray = [NSMutableArray arrayWithCapacity:[array count]];
for (id object in array) {
    if ([object isKindOfClass:[NSArray class]]) {
        if ([object count]) {
            [cleanedArray addObject:object[0]];
        }
        else {
            // empty array
        }
    }
    else if ([object isKindOfClass:[NSString class]]) {
        NSRange openBracket = [object rangeOfString:@"("];
        NSString *temp = [object stringByReplacingCharactersInRange:openBracket withString:@""];
        NSRange closeBracket = [temp rangeOfString:@")" options:NSBackwardsSearch];
        temp = [temp stringByReplacingCharactersInRange:closeBracket withString:@""];
        [cleanedArray addObject:temp];
    }
    else {
        // unknown class
    }
}

you might want to figure out if your objects are strings or arrays, and remove the superfluous part.
