Question

I am trying to create a search box to go with my UITableView, I am currently loading a JSON request into NSDictionaries and then using that to populate my table (all working fine)

I am using a second array of data to perform the search on from the search ba, but find that I cannot copy my original array.

This is my code, and the debug output:

NSDictionary * root = [responseString JSONValue];
//NSLog(root);

sortedArryData = [root objectForKey:@"add"];
NSLog(@"%@",sortedArryData);

[arryData arrayByAddingObjectsFromArray:sortedArryData];
NSLog(@"New: ");
NSLog(@"%@",arryData);

Output:

2011-12-12 21:24:39.264 app[18766:11603] Run
2011-12-12 21:24:40.677 app[18766:11603] (
    {
    address = "15 Southampton Road";
},
    {
    address = "Meeting House Lane";
}
)
2011-12-12 21:24:40.709 app[18766:11603] New: 
2011-12-12 21:24:40.709 app[18766:11603] (null)

Is there something i’m missing? both arryData and sortedArryData as NSMutableArray

Thanks

Answer 1

You probably have not initialized arryData, right before adding to the array go ahead and initialize it like so:

arryData = [NSMutableArray array];
[arryData arrayByAddingObjectsFromArray:sortedArryData];

EDIT:

Try this instead:

arryData = [NSMutableArray array];
[arryData addObject:sortedArryData];
