释放我的对象后，为什么我仍然得到retainCount = 1

Question

为什么在释放我的物品后我仍然得到retainCount = 1。

这是我的代码。任何人都可以帮我解决这个问题：

    newsDetail *newsdetails = [[newsDetail alloc] initWithNibName:@"newsDetail" bundle:nil];
    [newsdetails insertSomeData];

    NSLog(@"Object Count in memmory = %d",[newsdetails retainCount]);

    [self.view addSubview:newsdetails.view];
    NSLog(@"Object Count in memmory = %d",[newsdetails retainCount]);

    [newsdetails release];
    NSLog(@"Object Count in memmory = %d",[newsdetails retainCount]);

........

2011-09-20 10:26:10.212 memmory[1977:207] Object Count in memmory = 1
2011-09-20 10:26:10.213 memmory[1977:207] Object Count in memmory = 1

Answer 1

保留分配的对象，因此retain = 1; addSubview将retain count增加1，在release release中将retain减少1。

Answer 2

当您在某处将视图添加为子视图时，将保留此视图。
