How to fill this NSDictionary into a UITableView

[Wunk]

I'm parsing a piece of JSON into a NSDictionary, but I'm having some trouble sequencing this into an array of data which I can push into a UITableView

After parsing the JSON data I have this in a NSDictionary (this is the result from NSLog on the NSdictionary):

    1 =     {
        artist = "Bruno Mars";
        "artist_url" = "http://url.here/bruno-mars.htm";
        attributes =         {
            youtube = "http://www.youtube.com/v/7pNDpxkf3hk";
        };
        "lyric_url" = "http://url.here/just-the-way-you-are.htm";
        title = "Just the way you are";
    };
    2 =     {
        artist = "Duck sauce";
        "artist_url" = "http://url.here/duck-sauce.htm";
        attributes =         {
            youtube = "http://www.youtube.com/v/wWhtcU4-xAM";
        };
        "lyric_url" = "http://url.here/barbra-streisand.htm";
        title = "Barbra Streisand";
    };

etc.. until I have 40 results..

Basically what I want to do, is:

- Grab the results from 1 and stuff the variables into an array
- Parse the array (no issue here, once I have it actually IN there I can work with it no problem)
- Stick the results from 1 into the first indexPath.row entry of the UITableView (that'd be index 0)
- recycle the array, rince and repeat for entry 2 to 40

I could use some pointers for especially the first problem, specifically I need to grab JUST 1 entry from the NSDictionary and stuff it into an array..

You just need to iterate over the keys of the dictionary. However, dictionary keys are unordered so you need to make sure they're sorted in the order you expect. You can do something like:

NSArray *keys=[[dictionary allKeys] sortedArrayUsingSelector:@selector(compare:)];


for (NSNumber *key in keys) {
   NSDictionary *data=[dictionary objectForKey:key];
   //data should contain artist, artist_url, etc....
}

The above should work if your keys are NSNumbers (which it looks like from the json dump).

Doesn't seem to work, once I do (where self.jsonResult is the NSDictionary with data):

NSArray *keys=[self.jsonResult keysSortedByValueUsingSelector:@selector(compare:)];

It crashes with:

2010-12-01 18:21:45.661 MyApp[12481:207] -[__NSCFDictionary compare:]: unrecognized selector sent to instance 0x5d4a8c0


edit Actually never mind, either I misread or you changed something in the post, because once I altered it to NSArray *keys=[[self.jsonResult allKeys] sortedArrayUsingSelector:@selector(compare]; it worked

Thanks

Ya, I did edit my post. I mistakenly used keysSortedByValueUsingSelector which sorts by the value instead of the key.

Glad it worked.
