如何在Objective-C中创建NSDictionary？

我想创建一个类似这样的NSDictionary:

"zones": 
{
    {
        "zoneId": "1",
        "locations": 
        {
            {
                "locId": "1",
                "locZoneId": "1",
                "locLatitude": "33.68506785633641",
                "locLongitude": "72.97488212585449"
            },
            {
                "locId": “2”,
                "locZoneId": "1",
                "locLatitude": "33.68506785633641",
                "locLongitude": "72.97488212585449"
            },
            {
                "locId": “3”,
                "locZoneId": "1",
                "locLatitude": "33.68506785633641",
                "locLongitude": "72.97488212585449"
            },
        }
    }
}

但我不知道如何创造.

您应该使用数组和字典的组合.

字典初始化如下:

NSDictionary *dict = @{ key : value, key2 : value2};

数组初始化如下:

NSArray *array = @[Object1, Object2]
