PushViewController 和发布
我正在尝试这样做，带有注释的行效果很好，没有，当我从“推送”视图回来时，我的应用程序崩溃了......我应该什么时候[发布]？或者，更好的是，我这样做是正确的吗？
if (indexPath.row == 1) {
Credits *cr = [[Credits alloc] initWithNibName:@"Credits" bundle:nil];
[self.navigationController pushViewController:cr animated:YES];
//[cr release];
}else{
Search *sr = [[Search alloc] initWithNibName:@"Search" bundle:nil];
[self.navigationController pushViewController:sr animated:YES];
//[sr release];
}
I am trying to do like this, with the commented lines it works good, without, when I came back from the "pushed" view my App just crashes... when should I [release]? Or, better, I am doing this correctly?
if (indexPath.row == 1) {
Credits *cr = [[Credits alloc] initWithNibName:@"Credits" bundle:nil];
[self.navigationController pushViewController:cr animated:YES];
//[cr release];
}else{
Search *sr = [[Search alloc] initWithNibName:@"Search" bundle:nil];
[self.navigationController pushViewController:sr animated:YES];
//[sr release];
}

您应该在将控制器推入导航视图控制器的控制器堆栈后释放控制器。我的猜测是，您的
Search和Credits对象的 dealloc 中发生了其他事情，您在那里过度释放了一个对象。You should release your controller after pushing it onto the navigation view controller's stack of controllers. My guess is that something else is going on in the dealloc of your
SearchandCreditsobjects, that you are overreleasing an object there.
