obj-c中C ++的新增和删除命令 [英] New and delete command of c++ in obj-c

问题描述

我有一个对象的NSMutablearray.对象的数量由用户设置.在c ++中，我将使用for循环和'new'命令.类似这样:

I have an NSMutablearray of objects. the number of objects is set by user. in c++ I would use a for cycle and the 'new' command.something like this:

int fromuser, a;
for(a=0;a<fromuser;a++){
  array addobject:(new class obj) 
}

由于没有新内容，我需要在obj c中做什么?

what do I need to do in obj c since there is no new?

推荐答案

您将使用例如，类似以下的内容应该起作用:

For example, something like the following should work:

int fromuser, a;
NSMutableArray objectArray = [[NSMutableArray alloc] initWithCapacity:fromuser];
for (a = 0; a < fromuser; a++)
{
    MyObject *obj = [[MyObject alloc] init];
    [objectArray addObject:obj];
    [obj release]; //If not using ARC
}
