Several Methods for parsing iOS json: NSJSONSerialization, JSONKit, SBJson, TouchJson, and jsonkitsbjson

You can download related third-party class libraries from github.

1. NSJSONSerialization

The Code is as follows:

-(Void) viewDidLoad {[super viewDidLoad]; NSData * data1 = [NSData dataWithContentsOfFile: [[NSBundle mainBundle] pathForResource: @ "test" ofType: @ "json"]; // 1. NSLog (@ "% @", data1); _ autoreleasing NSError * err; NSDictionary * dic = [NSJSONSerialization JSONObjectWithData: data1 options: nsjsonreadingmutablaves error: & err]; NSLog (@ "% @", dic [@ "user"] [@ "location"]); NSLog (@ "% @", dic );}

2. JSONKit. This is the third-party class library to be imported.

 [super viewDidLoad];        NSString *path=[[NSBundle mainBundle]pathForResource:@"sina.json" ofType:nil];        NSData *data=[NSData dataWithContentsOfFile:path];            __autoreleasing NSError *err;        NSDictionary *dic=[data objectFromJSONDataWithParseOptions:JKParseOptionNone error:&err];        NSLog(@"%@",dic[@"user"][@"location"]);

 

3. SBJson also needs to import third-party class libraries

- (void)viewDidLoad {    [super viewDidLoad];    NSString *path=[[NSBundle mainBundle]pathForResource:@"sina.json" ofType:nil];    NSData *data=[NSData dataWithContentsOfFile:path];                SBJsonParser *jsonParser=[[SBJsonParser alloc]init];        NSMutableDictionary *dic=[jsonParser  objectWithData:data];    NSLog(@"%@",dic);    }

4. TouchJson third-party class library

- (void)viewDidLoad {    [super viewDidLoad];        NSString *path=[[NSBundle mainBundle]pathForResource:@"sina" ofType:@"json"];        NSData *data=[NSData dataWithContentsOfFile:path];     NSDictionary *dic=[[CJSONDeserializer deserializer] deserialize:data error:nil];        NSLog(@"%@",dic);    }
