Question

Hi I’m new with the Objective-C and i try to do some try.
I have an NSArray called “values”. It is an array of array. It seems like :

[“0” = > “aString”,6872,5523,0091]

[“1” = > “anotherString”,4422,1234,0091]

[“2” = > “aString”,6812,2143,0314] …

How do I sort the “values” array than the first integer value?
I should use the NSPredicate ?
please help me with some example.
thanks

Something like that with block (assuming that your integer value are NSNumber or some class that can be compared):

NSArray *sortArray = [yourArray sortedArrayUsingComparator: ^(id elt1, id elt2) {
    return [[elt1 objectAtIndex:1] compare:[elt2 objectAtIndex:1]];
    } ];
