iPhone - 从 UIWindow 启动 UIImagePickerController

Question

请问有什么可以发动UIImagePickerController从主的UIWindow从（无视图中定义） - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions ，上一个项目，其主窗口没有内置导航控制器到 IB（而不必在 IB 中添加一个）？

Answer 1

If you don't need UINavigationController then just place regular UIViewController as a root view for main windows. And present UIImagePickerController from it.

Example:

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    self.window.rootViewController = [[[UIViewController alloc] init] autorelease];
    UIImagePickerController *imagePickerController = [[[UIImagePickerController alloc] init] autorelease];
    [self.window.rootViewController presentModalViewController:imagePickerController animated:YES];
    [self.window makeKeyAndVisible];
    return YES;
}

Answer 2

self.window = [[[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]] autorelease];    
[window addSubview:imagePickerController.view];

That should accomplish what you want.
