对于这个API，我得到以下回复“http://maps.google.com/maps/api/geocode/json?sensor=false&address=No.3C-137,2nd地板，第二主干道，KASTuri Nagar，NGEF布局东部，Bennigana Halli，班加罗尔，卡纳塔克邦560043”
他的地址“NGEF布局东部Kasturi Nagar第二大道2楼3C-137号，Bennigana Halli，班加罗尔，卡纳塔克邦560043”我想提取纬度和经度。那里有许多address_components。必须考虑哪个地址，必须考虑哪个纬度和经度，即东北，西南，地区。

答案 0 :(得分：0)
这是带有键location
location = {
lat = "13.0048165";
lng = "77.6600505";
};
提供数据是一个字典（带有键results）。来自results的派生值是一个包含API所有可能位置的数组。每个地方（数组索引处的对象）是具有键geometry的子词典的字典。在这本词典中，您有另一本字典，其中包含location字典lat和lng。
如果我没有错，那将会是这样的
NSDictionary *aPlace=[[dict objectForKey:@"results"] objectAtIndex:someIndex];
NSDictionary *geomatry=[aPlace objectForKey:@"geometry"];
NSDictionary *location=[geomatry objectForKey:@"location"];
float lat=[[location objectForKey:@"lat"] floatValue ];
float lng=[[location objectForKey:@"lng"] floatValue ];
