优点， 1 只有2个文件

　　　 2 使用简单 

 

　　//Then import JSONKit.h” in your .m files where ever you need to parse a JSON response
　　import "JSONKit.h"

　　//Whenever you have JSON data that you need to parse (more on how to get some later), you just use the objectFromData method like so

　　NSData* jsonData = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&err];

　　NSDictionary *resultsDictionary = [jsonData objectFromJSONData];
　　Alternatively, if you have your data in string form, you can use the following:

　　NSDictionary *resultsDictionary = [jsonString objectFromJsonString];

　　//Once you have your dictionary, you can inspect it using the objectForKey method to get objects out of it.


 

   　　//[self stringAnalyst:pageSource];

　　for http://maps.google.com/geo?

        NSDictionary *resultsDictionary = [pageSource objectFromJSONString];

               

        NSArray* addressArray1 = [resultsDictionary objectForKey:@"Placemark"];

        NSLog(@"test");

        for (int i = 0; i< addressArray1.count; i++) {

            NSDictionary* temp = [addressArray1 objectAtIndex:i];

            NSString* address = [temp objectForKey:@"address"];

            NSLog(@"%@", address);

        }
