导航控制器上的内存管理

Question

我是iPhone SDK的新手，导航控制器上出现泄漏。 这里是我的代码：

- （空）SignupClicked：（ID）发送 {

if(appdelegate.isiPad){ 
    SignUpViewController *obj_SignUpViewController =[[SignUpViewController alloc] initWithNibName:@"SignUpViewControllerIpad" bundle:nil]; 
    [self.navigationController pushViewController:obj_SignUpViewController animated:YES]; 
    [obj_SignUpViewController release]; 
} 
else { 
    SignUpViewController *obj_SignUpViewController =[[SignUpViewController alloc] initWithNibName:@"SignUpViewController" bundle:nil]; 
    [self.navigationController pushViewController:obj_SignUpViewController animated:YES]; 
    [obj_SignUpViewController release]; 
} 

}

我在这些线路上越来越泄漏：

[self.navigationController pushViewController:obj_SignUpViewController animated:YES]; 
[self.navigationController pushViewController:obj_SignUpViewController animated:YES]; 

请帮我... 谢谢...

将视图控制器推到导航控制器上时，它将被保留。因此，您需要立即释放它，否则您将会泄漏。

[obj_SignUpViewController release];
