所以我有一个Json字典数据,如下所示
{
merchant = {
StoreID = 113;
};
token = {
Application = Merchant;
DatabaseID = 113;
DeviceToken = 9e7737daf0cb1e0572db47f520797adefd0367f66d5d6056f889732dcdb88772;
ID = 84;
LoginToken = "00000000-0000-0000-0000-000000000000";
OS = iOS;
};
}
之前的数据仅作为"令牌"部分和我将使用以下代码获取数据:
[userdefaults setObject:[json objectForKey:@"LoginToken"] forKey:@"loginToken"];
但是,数据已被修改为两个包装器,我无法获取正确的数据。例如,我如何获得" storeID"来自新数据??

您是否已将json-string转换为NSDictionary?
NSString *storeID = [(NSDictionary *)[json objectForKey:@"merchant"] objectForKey:@"StoreID"];
如果不是,您需要先转换它:
NSString *json_string = @"{\"merchant\": {\"StoreID\":\"123\"} }";
NSError *error;
NSDictionary *JSON =
[NSJSONSerialization JSONObjectWithData: [json_string dataUsingEncoding:NSUTF8StringEncoding]
options: NSJSONReadingMutableContainers
error: &error];
NSString storeID = JSON[@"merchant"][@"StoreID"];
NSLog(@"storeID: %@", storeID);
// Log output: storeID: 123

我更喜欢[关键]表示法:
NSString *storeID = json[@"merchant"][@"StoreID"];
