disable UIAppearance-API happen on RemoteViewControllers

Question

So i am styling all my views using the apprearance api. F.e. i style my `UINavigationBar` using: ``` [[UINavigationBar appearance] setBackgroundImage:navigationBarBgImage forBarMetrics:UIBarMetricsDefault]; ``` i want to use the advantage of the appearance api of styling all my `UINavigationBar`s in one single place (because i have multiple of them), so i don't want to do some subclassing only because of styling reasons. i also popup some `MFMessageComposeViewController`s and a `SLComposeViewController` to post to imessage or facebook. my problem here is, if i try to select albums on facebook or select contacts on imessage modalview, this happens: see the recursive description of the imessage modal view: ``` $0 = 0x1f1f1320 > | > | |

Accepted Answer

Your best bet is really to subclass one thing or the other. Otherwise you'll be undoing styles everywhere. I'll do it in one of two ways:

One is to subclass `UINavigationController` and style the `UINavigationBar` contained by that class:

```
UINavigationBar *navigationBarProxy = [UINavigationBar appearanceWhenContainedIn:[MyNavigationController class], nil]; // 
[navigationBarProxy setBackgroundImage:navigationBarBackgroundImage forBarMetrics:UIBarMetricsDefault];
// and so on
```

Another method is to subclass `UINavigationBar` instead, set the appearance for that class, and instantiate your `UINavigationController` this way:

```
UINavigationController *navigationController = [[UINavigationController alloc] initWithNavigationBarClass:[MyNavigationBar class] toolbarClass:nil];
// navigationController now has a navigationBar of your preferred type
```
