我很难找出pushViewController是否保留了控制器,目前我有以下代码(有效)...

ColorController *colorController = [[ColorController alloc] initWithNibName:nibColor bundle:nil];
[[self navigationController] pushViewController:colorController animated:YES];
[colorController release];

但我正在考虑删除发布并添加自动释放...

ColorController *colorController = [[[ColorController alloc] initWithNibName:nibColor bundle:nil] autorelease];
[[self navigationController] pushViewController:colorController animated:YES];

非常感激
