是否可以在一个键下设置一个NSMutableDictionary键？

Question

我设置value与key像这样：

[mutableDict setObject:@"Object to set" forKey:@"KeyOne"]; 

这工作，但现在我想补充一个value"Key one"下，像这样：

[mutableDict setObject:@"Object a" forKey:@"KeyOne/detailsOnKey"]; 

这甚至可能吗？所有的帮助表示赞赏

Answer 1

听起来像你想你的字典里一本字典，dawg

mutableDict[@"KeyOne"] = @{@"detailsOnKey": @"Object"} 

然后你就可以访问该嵌套的字典是这样的：

mutableDict[@"KeyOne"][@"detailsOnKey"] 

Answer 2

您可以使用此多个词典。

//add a dictionary as the object for KeyOne 
[mutableDict setObject:[[NSMutableDictionary alloc] init] forKey:@"KeyOne"]; 

//add "Object a" under key one 
[(NSMutableDictionary *)[mutableDict objectForKey:@"KeyOne"] setObject:@"Object a" forKey:@"detailsOnKey"]; 

//如何获得keyone/detailsonkey回？，这样你可以把它找回来

id objectA = [(NSMutableDictionary *)[mutableDict objectForKey:@"KeyOne"] objectForKey:@"detailsOnKey"];
