I'm using this to get the auto suggestion from Youtube.
["Tire",[["tired",0],["tired lyrics",0],["tired alan walker remix",0],["tired remix",0],["tired alan walker cover",0],["tired of being sorry enrique iglesias",0],["tire",0],["tired cover",0],["tiren mati kemaren full movie",0],["tired of talking",0]],{"k":1,"q":"raN20uYZUrouYBB7VsB396HlA88"}]
As you can see from above to extract the information from above, I am using this code to extract the information such as tired, tired lyrics, tired alan walker from the JSON array.
NSString *json = nil;
NSScanner *scanner = [NSScanner scannerWithString:str];
[scanner scanUpToString:@"[[" intoString:NULL]; // Scan to where the JSON begins
[scanner scanUpToString:@"]]" intoString:&json];
NSLog(@"json before = %@", json);
//The idea is to identify where the "real" JSON begins and ends.
json = [NSString stringWithFormat:@"%@%@", json, @"]]"];
but sometimes the JSON array might be this format as shown below.
["Like",[["likey",0,[131]],["likey twice lyrics",0,[3]],["likey dance",0,[3]],["likey dance practice",0,[3]],["likey live",0,[3]],["like i\u0027m gonna lose you",0],["like ooh ahh",0],["like a boss",0],["like a g6",0],["like a stone",0]],{"k":1,"q":"9DuLDtNkAUfZ2X9AVZN90t0Zxlw"}]
How can i extract the information above example like likey, likey twice lyrics ?
NSScanner isn't the best API for turning raw JSON into useful data.
You would be best served by using the native JSON API NSJSONSerialization
id json = [NSJSONSerialization JSONObjectWithData:data options:0 error:nil];
The json object can be cast into NSArray in your case here.
where the data is the raw data from the response.
