Question

我有一个NSDictionary和一个NSMutableArray而我想存储从NSDictionary许多对象到NSMutableArray从一个键，但我不知道它。

这是我的代码：

//NSArray * a = [[NSArray alloc]initWithObjects:@"1",@"2",@"3",@"4",@"7",@"9", nil]; 
//NSArray *b = [[NSArray alloc]initWithObjects:@"1",@"2",@"3",@"4",@"5",@"0", nil]; 
NSDictionary * dic = [NSDictionary dictionaryWithObjectsAndKeys:a,@"number1",b,@"number2", nil]; 

NSMutableArray *array = [NSMutableArray alloc].... ? 

我想从NSDictionary在NSMutableArray

Answer 1

NUMBER1密钥存储对象，因为它似乎您存储阵列作为NSDictionary元素，你可以这样做：

NSMutableArray *array = [[NSMutableArray alloc] initiWithArray:dic[@"number1"]]; 

或

NSMutableArray *array = [NSMutableArray arrayWithArray:dic[@"number1"]]; 

Answer 2

要添加对象插入NsDictionary阵列做：

NSMutableDictionary * datos = [array objectAtIndex:i]; 
[datos setObject:@"hola" objectForKey@"newKey"];
