是否可以在一個鍵下設置一個NSMutableDictionary鍵？

Question

我設置value與key像這樣：

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

這工作，但現在我想補充一個value"Key one"下，像這樣：

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

這甚至可能嗎？所有的幫助表示讚賞

Answer 1

聽起來像你想你的字典裏一本字典，dawg

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

然後你就可以訪問該嵌套的字典是這樣的：

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

Answer 2

您可以使用此多個詞典。

//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"]; 

//如何獲得keyone/detailsonkey回？，這樣你可以把它找回來

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