iPhone - 从 UIWindow 启动 UIImagePickerController

Question

如何从 - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions 的主 UIWindow （未定义视图）启动 UIImagePickerController主窗口没有内置导航控制器进入 IB 的项目（并且无需向 IB 添加导航控制器）？

Answer 1

如果您不需要 UINavigationController，那么只需将常规 UIViewController 作为主窗口的根视图即可。并从中呈现 UIImagePickerController 。

例子：

- (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];

这应该可以实现你想要的。
