在 UIStoryboard 的 UITabBarController 中配置 UIImagePickerController

Question

我有一个使用故事板的项目。初始 ViewController 是一个 UITabBarController，它托管两个 ViewController，第一个是 UIImagePickerController。

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

Answer 1

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;
}
