如何从字典中获得价值

Question

everyone!

Please help me to get the total value from given dictionary

 {
    "@averageBaseRate" = "296.7";
    "@averageRate" = "296.7";
    "@commissionableUsdTotal" = "1186.8";
    "@currencyCode" = USD;
    "@maxNightlyRate" = "296.7";
    "@nightlyRateTotal" = "1186.8";
    "@total" = "1186.8";
    NightlyRatesPerRoom =     {
        "@size" = 1;
        NightlyRate =         {
....

How can I get the value from total key. Neither I can apply valueForKey nor I can apply objectForKey.

Any help is highly appreciated !

Answer 1

It looks strange that you have "@total" instead of "total" - looks like @ is a part of NSString. Probably you created a NSString @"@total" which sounds like a bug. You should be able to access it with:

[dict objectForKey:@"@total"];

Answer 2

您可以使用它。

float total = [[yourDict objectForKey:@"@total"] floatValue];

Answer 3

Hey Buddy always use like this ........

with this line you get all value of ABC Key In your Array

                 [array addObject:[dict objectForKey:@"ABC"]];

Answer 4

如今，您甚至可以使用yourDict[@"yourkey"]来获取为key存储的值。
