Write content of NSURL to an array - ios

Question

I have a program that retrieves data from a link and i write it out to the Log like this.
NSURL *getURL=[NSURL URLWithString:#"link.php"];
NSError *error=nil;
NSString *str=[NSString stringWithContentsofURL:getURL encoding:NSUTF8StringEncoding error:&error];
NSLog(#"%",str);
This prints to the log the three values from my php as expected.
However I am having a little difficulty saving this in an array which then displays it those values in a UISplitviewController (the leftcontroller side).
which is written like this
showArray=[[NSMutableArray alloc]initWithContentofURL:getURL];
then in cellForRowAtIndexPath: method is
cell.textLabel.text=[showArray object atIndex:indexPath.row];
A second thing i have tried is write myURL to an array and tried to initlize showArray with ContentsofArray like this
NSArray *retults=[NSArray arraywithContentsOFURL:getURL];
showArray=[[NSArray alloc]initWithArray:retults];
but THAT dont work
BUT if i say
showArray=[[NSMutableArray alloc]initWithObjects:#"One",#"Two",nil];
One and two shows in my leftview controller....
Would love is someone could help me with this...Thank you

Answer 1

Are you trying to add the contents of the URL or the URL itself ?
If you are trying to just add the URL, then use :
showArray = [#[getURL] mutableCopy];
However, if you are trying to add the contents of the URL, then the doc clearly states that the URL must represent a string representation of an array.
Furthermore :
Returns nil if the location can’t be opened or if the contents of the location can’t be parsed into an array.
EDIT :
I saw your comment on your post and your data looks like JSON data.
You should take a look at the NSJSONSerialisation class which is pretty straightforward to use (you'll find lots of example here on SO).

Answer 2

U have done web services perfectly, now wat u have to do is parse it to an array
First download the SBJSON files in this link
https://github.com/stig/json-framework/
Then, copy them to your workspace.
Then, in the viewController add this
#import "SBJson.h"
Your JSON data contains values in the form of dictionary
SO, to parse them
SBJsonParser * parser=[SBJsonParser new];
NSDictionary * jsonData=(NSDictionary *)[parser objectWithString:outputData];
NSArray * arr=(NSArray *)[NSDictionary objectForKey:#"animal"];
I think this will help
