问题描述
我正在尝试从嵌套的JSON响应下面获取一些键和值.下面我已经提到了我的JSON响应结构，我需要从下面的响应中获取所有keys(Red, Green)和键values(Color and ID)，并将其加载到Array中以获取tableview单元格值.
I am trying to get some keys and values from below nested JSON response. Below I have mentioned my JSON response structure, I need to get the all keys(Red, Green) and key values(Color and ID) from the below response and load into the Array for tableview cell value.
仅供参考::我尝试使用NSDictionary进行操作，但是我一直都在获取无序值.我还需要获取有序值.请帮帮我！
FYI: I have tried by using NSDictionary but I am getting all the time unordered values. I need to get ordered values also. Please help me!
{
response: {
RED: {
Color: "red",
color_id: "01",
},
GREEN: {
Color: "green",
color_id: "02",
}
},
Colorcode: { },
totalcolor: "122"
}
我的代码:
NSError *error;
NSDictionary *jsonDictionary = [NSJSONSerialization JSONObjectWithData:data options:kNilOptions error:&error];
NSArray *responsData = [jsonDictionary objectForKey:@"response"];
NSLog("%@",[responsData objectAtIndex:0]); // here I am getting bad exception
NSDictionary *d1 = responsData.firstObject;
NSEnumerator *enum1 = d1.keyEnumerator;
NSArray *firstObject = [enum1 allObjects];
推荐答案
我已经通过编码创建了JSON数据，所以不要认为只是检查以下答案
I have create JSON data through coding so don't consider it just check the following answer
/// Create dictionary from following code
/// it just for input as like your code
NSMutableDictionary * dict = [[NSMutableDictionary alloc] init];
NSMutableDictionary * innr = [[NSMutableDictionary alloc] init];
[innr setObject:@"red" forKey:@"Color"];
[innr setObject:@"01" forKey:@"color_id"];
NSMutableDictionary * outer = [[NSMutableDictionary alloc] init];
[outer setObject:innr forKey:@"RED"];
innr = [[NSMutableDictionary alloc] init];
[innr setObject:@"green" forKey:@"Color"];
[innr setObject:@"02" forKey:@"color_id"];
[outer setObject:innr forKey:@"GREEN"];
[dict setObject:outer forKey:@"response"];
// ANS ------ as follow
// get keys from response dictionary
NSMutableArray * key = [[NSMutableArray alloc] initWithArray:[dict[@"response"] allKeys]];
// sort as asending order
NSSortDescriptor* sortOrder = [NSSortDescriptor sortDescriptorWithKey: @"self" ascending: YES];
key = (NSMutableArray *)[key sortedArrayUsingDescriptors: [NSArray arrayWithObject: sortOrder]];
// access inner data from dictonary
for (NSString * obj in key) {
NSLog(@"%@",dict[@"response"][obj][@"Color"]);
NSLog(@"%@",dict[@"response"][obj][@"color_id"]);
}
