我有一个使用故事板的项目。最初的 ViewController 是一个 UITabBarController,它承载了两个 ViewController,其中第一个是 UIImagePickerController。

我应该在哪里配置 UIImagePickerController(设置它的 sourceType 等)?

在应用程序委托中怎么样?

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    // Override point for customization after application launch.

    UITabBarController *tabBarController = (UITabBarController *)[self.window rootViewController];

    // Per OP, first view controller in the tab bar is the UIImagePickerController.
    UIImagePickerController *imagePicker = [tabBarController.viewControllers objectAtIndex:0];

    // Your configuration code here: 
    // imagePicker.sourceType = <your code here>

    return YES;
}
