目标C语言 复制NSDictionary到NSArray

Question

我有一个变量声明为NSDictionary。我怎么把它复制到extern const NSArray变量?例如:

NSMutableDictionary *selectedItem = [self.dataArray objectAtIndex:indexPath.row];
[selectedItem setObject:[NSNumber numberWithBool:targetCustomCell.checked]     
                 forKey:@"checked"];

Answer 1

allKeys返回包含所有键的NSArray。allValues返回包含所有值的NSArray。

NSArray *keys = [myDict allKeys];
NSArray *values = [myDict allValues];
