Answer 1

Ich habe versucht, eine Demo-Szenario mit Ihrem JSON Wert zu schaffen

Hier

ist der Code:

- (void)viewDidLoad { 
    [super viewDidLoad]; 

    NSString *str = @"[{\"TheatreName\": \"FunCinemas\",\"TheatreId\": 1,\"City\":\"Chandigarh\"},{\"TheatreName\":\"PVRElanteMall\",\"TheatreId\": 2,\"City\": \"Chandigarh\"},{\"TheatreName\": \"PiccadilySquare\",\"TheatreId\": 3,\"City\": \"Chandigarh\"}]"; 
    NSData *data = [str dataUsingEncoding:NSUTF8StringEncoding]; 

    NSError *err = nil; 
    NSArray *jsonData = [NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingAllowFragments error:&err]; 

    NSMutableArray *arrResult = [NSMutableArray array]; 

    for (NSDictionary *dict in jsonData) { 

     NSLog(@"TheatreName %@", dict[@"TheatreName"]); 
     NSLog(@"TheatreId %@", dict[@"TheatreId"]); 
     NSLog(@"City %@", dict[@"City"]); 

     [arrResult addObject:dict]; 
    } 

}
