釋放對象后，為什么我仍然保持retainCount = 1

Question

釋放對象后，為什么我仍然保持retainCount = 1 。

這是我的代碼。 誰能幫我解決這個問題：

    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 10:26:10.208 memmory[1977:207] Object Count in memmory = 1
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

分配的對象被保留，因此retain = 1; addSubview將保留計數增加1，在發布調用中將保留減少1。

Answer 2

當您在某處將視圖添加為子視圖時，將保留該視圖。
