Question

i have a problem in my app. in an tabbarcontroller i have a login view where i can enter a website. if the login data is correct the view switches to another view. works fine.

now my problem is, when i switch the tab and enter the login view tag again and try to login again, the view does not load.

Whats here the problem? should i dismissmodalviewcontroller when the view is unload or something else???

thanks for help,

EDIT1:
hi robin, in my login view is an button which calls a webview whit this code:

ShopWebViewController *shopWVC = [[ShopWebViewController alloc]     initWithNibName:@"ShopWebViewController" bundle:nil];
    shopWVC = [[ShopWebViewController alloc] initWithNibName:@"ShopWebViewController" bundle:nil];
shopWVC.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal;
[logView  presentModalViewController:shopWVC animated:YES];  

And now when i exit the tabbar item where this logview is and enter it again, then the first view appears and the login/presentmodalviewcontroller doesnt work again.
cause of this i think that i may have to dismissmodalviewcontroller but dont know if this is right or not.

When you hit the login button:

ShopWebViewController *shopWVC = [[ShopWebViewController alloc] initWithNibName:@"ShopWebViewController" bundle:nil];
shopWVC.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal;
[self presentModalViewController:shopWVC animated:YES];
[shopWVC release];

Then in your view controller that has just been presented modally, somewhere in your code (perhaps when login is successful?) you need to dismiss it with

[[self parentViewController] dismissModalViewControllerAnimated:YES];
