###我写了下面的代码
- (int)my_test:(int)sender {
NSMutableDictionary *dic1 = [NSMutableDictionary new];
NSMutableDictionary *dic2 = [NSMutableDictionary new];
[dic2 setObject:@"wode" forKey:@"name"];
[dic1 setObject:@"test" forKey:@"value"];
int temp = 2;
[dic1 setObject:@(temp+sender) forKey:@"value1"];
return 2;
}

###这里我有几个不解的
- 1.000000010000f000 这内存地址的代码他是怎么解析的为什么他写的根本不对啊虽然我项目里有这些类但是这个方法根本没有使用是不是我设置的不对
- 2.如何知道name这个key是设置给第一个生成的NSMutableDictionary对象还是第二个
- 3.如果确定value1这个key的值因为这之中有新声明了个变量而且加上原有变量的
- 4.变量声明之后不是会给他一个内存空间吗 这怎么确定的 我怎么知道对象在哪里
- 5.在执行一个方法之后如果有返回值他存储在哪里
