从其他NSMutableDictionary保存和检索NSMutableDictionary

Question

我有一个NNDictionary，我想将它存储在另一个NSMutableDictionary。我做了这种方式：

NSDictionary* dictionary = (NSDictionary*) [NSKeyedUnarchiver unarchiveObjectWithData:context]; 
    [myDictionarySTORE setObject:dictionary forKey:[NSString stringWithFormat:@"%d", r]]; 

要提取它，然后我做的：

NSDictionary* dic = [myDictionarySTORE objectForKey:[NSString stringWithFormat:@"%ld", (long)btn.tag]]; 
NSString *Name = [dic objectForKey:@"fileName"]; 
NSString *Type = [dic objectForKey:@"fileType"]; 
NSData *File = [dic objectForKey:@"FileData"]; 

凡btn.tag在这种情况下，为r。关键是相同的，但它似乎并没有工作...

Answer 1

NSDictionary * dic = [NSDictionary dictionaryWithDictionary：[NDString stringWithFormat：@“％ld”，（（long）btn.tag] ]];

或者

的NSDictionary * DIC = [[NSDictionary中的alloc] initWithDictionary：[myDictionarySTORE objectForKey：[的NSString stringWithFormat：@ “％LD”，（长）btn.tag]]];
