将NSDictionary复制到NSArray

Question

我有一个变量声明为NSDictionary.如何将其复制到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NSArray包含所有键的内容.allValues返回NSArray包含所有值的内容.

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