ios - 解析两个 JSON 对象

Question

当我发送 API 时，我收到这样的 JSON 响应。

{"ABC":[{"ID1":"response","ID2":"response","ID3":"response","ID4":"response","ID5":"response"},{"ID1":"response","ID2":"response","ID3":"response","ID4":"response","ID5":"response"},{"ID1":"response","ID2":"response","ID3":"response","ID4":"response","ID5":"response"}],"status":"OK","count":3}

{"XYZ":[{"id1":"response"},{"id1":"response"},{"id1":"response"}],"status":"OK","count":3}

我在响应中得到了两个 JSON 对象。如何将此数据存储在 MutableArrays 中。

我的代码是...

//Getting data from server through JSON approach ...
self.urlSession = [NSURLSession sessionWithConfiguration:[NSURLSessionConfiguration defaultSessionConfiguration]];
self.urlReq= [NSMutableURLRequest requestWithURL:[NSURL URLWithString:[[NSString alloc] initWithFormat:@"http://MyApiName"]]];

self.dataTask = [self.urlSession dataTaskWithRequest:self.urlReq completionHandler:^(NSData * _Nullable data, NSURLResponse * _Nullable response, NSError * _Nullable error) {
        
        if (!(data == nil)) {
            
            self.loginDic = [NSJSONSerialization JSONObjectWithData:data options:0 error:nil];
            NSLog(@"data : %@", data);
            NSLog(@"Login Dic : %@", [self.loginDic objectForKey:@"ABC"]);

            if (!(self.loginDic == nil)) {
                
                self.integer = [[self.loginDic objectForKey:@"ABC"] count];
                
                if ([[self.loginDic objectForKey:@"status"] isEqualToString:@"OK"] && (!(self.integer == 0))) {
                    
                    self.ID1 = [[NSMutableArray alloc]init];
                    self.ID2 = [[NSMutableArray alloc]init];
                    self.ID3 = [[NSMutableArray alloc]init];
                    self.ID4 = [[NSMutableArray alloc]init];
                    self.ID5 = [[NSMutableArray alloc]init];
                    
                    for (int i=0; i<self.integer; i++) {
                            
                        [self.ID1 addObject:[[[self.loginDic objectForKey:@"ABC"] objectAtIndex:i] objectForKey:@"ID1"]];
                        [self.ID2 addObject:[[[self.loginDic objectForKey:@"ABC"] objectAtIndex:i] objectForKey:@"ID2"]];
                        [self.ID3 addObject:[[[self.loginDic objectForKey:@"ABC"] objectAtIndex:i] objectForKey:@"ID3"]];
                        [self.ID4 addObject:[[[self.loginDic objectForKey:@"ABC"] objectAtIndex:i] objectForKey:@"ID4"]];
                        [self.ID5 addObject:[[[self.loginDic objectForKey:@"ABC"] objectAtIndex:i] objectForKey:@"ID5"]];                                
                    }
                    
                    NSLog(@"%@", self.ID1);
                    NSLog(@"%@", self.ID2);
                    
                } else {
                    
                }
                
            } else {
            
            }
            
        } else {
            
        }
        
    }];
    
    [self.dataTask resume];

}

我正在获取数据，但我得到的是 loginDic = null。

在你得到 AB 之后，它的 Dictionary 数组

您可以轻松地使用此 valueForKeyPath，例如:

   NSArray * AB = @[@{
                      @"ID1":@"response",
                       @"ID2":@"response",
                      @"ID3":@"response",
                      @"ID4":@"response",
                      @"ID5":@"response",
                     },@{
                @"ID1":@"response",
                @"ID2":@"response",
                @"ID3":@"response",
                @"ID4":@"response",
                @"ID5":@"response"
                }];



    NSArray * ID1 = [AB valueForKeyPath:@"ID1"];
    NSArray * ID2 = [AB valueForKeyPath:@"ID2"];
