Create an Array of Strings of a sheet column stored at Parse.com

Question

This supposed to be a simple thing to do, but i`m having a hard time to find this answer.

X-Code / Objective-C:

I have an sheet stored at Parse.com, and I simply want to make a array with one of its columns. For example, I have a spread sheet called Places and I want to build an Array of the column Address of these places, but instead I`m getting an Array of objects. Look!

PFQuery *query = [PFQuery queryWithClassName:@"Locais"];
[query selectKeys:@[@"local"]];
[query findObjectsInBackgroundWithBlock:^(NSArray *objects, NSError *error) {


    self.colorArray = [NSArray arrayWithObject:objects];


    NSLog(@"%@", objects);


}];

The log:

"<Locais:fEQq2qB8dJ:(null)> {\n    local = \"Giga CCM/CCS\";\n}",
"<Locais:z3gHNJ7CPw:(null)> {\n    local = \"Giga Santander\";\n}",
"<Locais:rNEJUHPXtl:(null)> {\n    local = \"Sean Plott\";\n}"

How I want to get the log:

"Giga ccm/css" "Giga santander" "Sean Plott"

Answer 1

You can get the array of strings in a single step using Key-Value Coding (KVC),

self.colorArray = [objects valueForKeyPath:@"local"];

You should have a look on Key-Value Coding Programming Guide

Answer 2

You can extract the data from the array like this :

PFObject *localis = objects[1];
NSString *string = [localis objectForKey:@"local"];

This is how you can get the data out of it.
