【问题描述】：

"[
  
    \"TheatreName\": \"FunCinemas\",
    \"TheatreId\": 1,
    \"City\": \"Chandigarh\"
  ,
  
    \"TheatreName\": \"PVRElanteMall\",
    \"TheatreId\": 2,
    \"City\": \"Chandigarh\"
  ,
  
    \"TheatreName\": \"PiccadilySquare\",
    \"TheatreId\": 3,
    \"City\": \"Chandigarh\"
  
]"

我想解析这些数据，即分离所有对象 Theatrename, id, city

【参考方案1】：

我尝试使用您的 JSON 值创建一个演示场景

代码如下：

- (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];
