Ios NSD字典格式

谁能帮我创建以下结构的NSDictionary格式：

{
key1 = "value1";
    key2 = "value2";
    key3 =     [
                {
            key01 = "value01";
            key02 = "value02";
        },
                {
            key01 = "value01";
            key02 = "value02";
        },
                {
            key01 = "value01";
            key02 = "value02";
        }
    ];
}

试试这段代码，它可能会对你有所帮助

NSDictionary *dicationary = @{
                                  @"key1":@"value1",
                                  @"key2":@"value2",
                                  @"key3":@[@{@"key01":@"value01",@"key02":@"value02"},
                                            @{@"key01":@"value01",@"key02":@"value02"},
                                            @{@"key01":@"value01",@"key02":@"value02"}]
                                  };

以下内容适用于您：

NSString *jsonString = @"{\"ID\":{\"Content\":268,\"type\":\"text\"}}";
NSData *data = [jsonString dataUsingEncoding:NSUTF8StringEncoding];
NSDictionary *jsonDict = [NSJSONSerialization JSONObjectWithData:data options:0 error:nil];

NSLog(@"%@", jsonDict[@"ID"][@"Content"]);

将返回给您：

268

obj-c中有API可以将Json转换为nsdictionary。我想您应该试试：

首先将json转换为nsdata（假设上面的json是字符串格式）

2.然后使用API将其转换为NSDictionary：

NSDictionary *dictionary = [NSJSONSerialization JSONObjectWithData:data options:kNilOptions error:&error];

为了回答您关于将JSON数据转换为NSDictionary的问题，这里是：

（假设您已经获得JSON数据）

这是NSDictionary格式，您想问什么？如何编写此json结构？您想将其转换为NSDictionary吗？格式很重要，它使此代码易于理解。

// add the first 2 VALUES with it's KEYS
NSMutableDictionary *mainDict = [NSMutableDictionary dictionary];
[mainDict setValue:VALUE1 forKey:KEY1];
[mainDict setValue:VALUE2 forKey:KEY2];

// then for the last KEY, create a mutable array where you will store your sub dictionaries
NSMutableArray *ma = [NSMutableArray array];
NSMutableDictionary *subDict = [NSMutableDictionary dictionary];
[subDict setValue:SUB_VALUE1 forKey:SUB_KEY1];
[subDict setValue:SUB_VALUE1 forKey:SUB_KEY2];
[ma addObject:subDict];

// then add that array to your main dictionary
[mainDict setValue:ma forKey:KEY3];

// check the output
NSLog(@"mainDict : %@", mainDict);

// SAMPLE DATA - Test this if this is what you want
NSMutableDictionary *mainDict = [NSMutableDictionary dictionary];
[mainDict setValue:@"value1" forKey:@"key1"];
[mainDict setValue:@"value2" forKey:@"key2"];

NSMutableArray *ma = [NSMutableArray array];
NSMutableDictionary *subDict = [NSMutableDictionary dictionary];
[subDict setValue:@"subValue1" forKey:@"subKey1"];
[subDict setValue:@"subValue2" forKey:@"subKey2"];
[ma addObject:subDict];

[mainDict setValue:ma forKey:@"key3"];

NSLog(@"mainDict : %@", mainDict);
