ios - get values from NSDictionary

Question

I have JSON on my server, which is parsed into iOS app to NSDictionary. NSDictionary looks like this:

(
        {
        text = Aaa;
        title = 1;
    },
        {
        text = Bbb;
        title = 2;
    }
)

My question is - how to get just text from first dimension, so it should be "Aaa". I've tried to use this:

[[[json allValues]objectAtIndex:0]objectAtIndex:0];

But it didn't work, it ends with error

Terminating app due to uncaught exception
'NSInvalidArgumentException', reason: '-[__NSCFArray allValues]:
unrecognized selector sent to instance 0x714a050'

So can you help me please, how to get just one value from specified index? Thanks!

Answer 1

That error message is simply telling you that NSDictionary (which is the first object of that array, along with the second) doesn't respond to objectAtIndex.

This will be a bit cody, but it explains it better:

NSArray *jsonArray = [json allValues];
NSDictionary *firstObjectDict = [jsonArray objectAtIndex:0];
NSString *myValue = [firstObjectDict valueForKey:@"text"];

Answer 2

Your JSON object is an array, containing two dictionaries. That's how to get the values:

NSDictionary* dict1= json[0];
NSString* text= dict1[@"text"];
NSString* title= dict1[@"title"];
