導航控制器上的內存管理

Question

我是iPhone SDK的新手，導航控制器上出現泄漏。 這裏是我的代碼：

- （空）SignupClicked：（ID）發送 {

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]; 
} 

}

我在這些線路上越來越泄漏：

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

請幫我... 謝謝...

將視圖控制器推到導航控制器上時，它將被保留。因此，您需要立即釋放它，否則您將會泄漏。

[obj_SignUpViewController release];
