Question

我需要某种帮助来解释如何使用 NSDirectory，我不知道是否可以从 class "A" 中插入 NSString 或 NSDictionary 的数据class B

中的 NSDictionary

Class一个

String
NSString *TwitterToken = accessTokenTwt;
NSString *twitterSecretToken = accessTokenSecret;

NSDictionary take the tokenExpires or another

- (NSMutableDictionary *)tokenAsDictionary
{
NSMutableDictionary *tokenDictionary = [[NSMutableDictionary alloc] init];

tokenDictionary[@"key"] = self.key;
tokenDictionary[@"secret"] = self.secret;
tokenDictionary[@"tokenExpires"] = @(self.tokenExpires);
tokenDictionary[@"requestAuthUrl"] = self.requestAuthUrl;
if (self.verifier) {
    tokenDictionary[@"verifier"] = self.verifier;
}

return tokenDictionary;
}

Class乙

NSMutableDictionary *args = [[NSMutableDictionary alloc] init];

    [args setObject: [Insert here data from class A] forKey:@"access_token"];
    [args setObject: @"1" forKey:@"expires"];

一个NSMutableDictionary（或NSDictionary）可以有任何对象作为值：字符串、字典、数组等。不管是什么类型，你检索它都是一样的。如果您在其中存储字典，则只需再钻一个级别即可查看该字典的数据（不过您必须将其转换为字典）。

随后的伪代码...

Dictionary a = ...;
a[@"keyA"] = "hi A";
Dictionary b = ...;
b[@"keyB"] = a;

// You now have the dictionary "a" stored inside dictionary "b" with a key of "keyB".

Dictionary c = b[@"keyB"];

// Dictionary c is now, essentially, Dictionary a

// c[@"keyA"] will return to you "hi A"
