Answer 1

这是 NSMutableDictionary。您可以搜索示例代码。 例如:Create dict

NSMutableDictionary *dictionary = [NSMutableDictionary dictionary];
[dictionary setObject:@"object1" forKey:@"key1"];

打印字典的所有键和值:

for (NSString* key in [dictionary allKeys]) {
   NSLog(@"key: %@, value: %@", key, [dictionary objectForKey:key]);
}
