Pull a specific key from an array objective c

Question

in PHP when using an array you can use myArray['firstElement'] to pull that specific key and its associated values from the array. How do I do this similar type of thing in objective c?

When you say 'array', do you mean a primitive array like int[], an ordered collection like NSArray, or an associative collection like NSDictionary? — aroth

an NSArray but I solved my problem. By using [myArray objectForKey:@"firstElement"]; it returns that specific segment. thanks — Mike Silvis

If you're new to Obj-C, please read the guide The Objective-C Programming Language. — jtbandes

If you want to deal with key-value pairs, you would use an NSDictionary.

Although it is surprising to note that arrays in PHP are an ordered map.

To access the key use [dict valueForKey:@"key"]

You want to use NSDictionary instead of NSArray. NSDictionary is an associative array.
