关于如何使用NSMutableDictionary
并使其成为另一个我无法理解的NSMutableDictionary
的孩子,必定会有一些缺失的关键元素。我已经尝试了所有的东西,我开始认为跳下桥可能会解决问题。
电流:
DICT:1 root
|_main dict
DICT:2 root
|_dict [A]
|
sub dict...
所需:
DICT:1 root
|_main dict
|_dict [A]
|
sub dict....
任何时候我尝试将“DICT:2”添加到“DICT:1”时它会覆盖主要词典。离开我:
DICT:1 root
|_dict [A]
|
sub dict...
我尝试了很多东西,包括:
NSMutableDictionary *myDict = [[NSMutableDictionary alloc] init];
[myDict setObject:@"mainDict" forKey:@"mainDict"];
[myDict setObject:@"dictA" forKey:@"mainDict"];
也尝试过:
NSMutableDictionary *myDict = [[NSMutableDictionary alloc] init];
[myDict addEntriesFromDictionary:dictA];
NSMutableDictionary *moarDict = [myDict objectForKey:@"mainDict"];
[moarDict addEntriesFromDictionary:dictA];
和:
moarDict = [dictA mutableCopy];
啊! NSMutableDictionary
必须恨我,因为毫无疑问我讨厌它。
答案 0 :(得分:1)
试试这个:
NSMutableDictionary *myDict = [[NSMutableDictionary alloc] init];
NSMutableDictionary *mainDict = [[NSMutableDictionary alloc] init];
[myDict setObject:mainDict forKey:@"mainDict"];
[myDict[@"mainDict"] setObject:dictA" forKey:@"dictA"];
这导致
myDict
| mainDict
| dictA
| sub dict
