嗨,提前感谢。
我有一个我编写的应用程序,它使用 3D 触摸在主屏幕上使用新的 UIApplicationShortcut。一旦应用程序成为应用程序,快捷方式就可以使用,但如果应用程序关闭,则快捷方式在主屏幕上不起作用。
当应用程序关闭时,快捷方式会启动应用程序,但快捷方式不起作用,只会启动应用程序。
这是我用于快捷方式的两种方法。
- (void)setupViewControllers {
// setup the navigation stack
CGSize iOSDeviceScreenSize = [[UIScreen mainScreen] bounds].size;
if (iOSDeviceScreenSize.height == 480)
{
_navigationController = (UINavigationController *)self.window.rootViewController;
// iPhone 5 and iPod Touch 5th generation: 4 inch screen
// Instantiate a new storyboard object using the storyboard file named Storyboard_iPhone4
UIStoryboard *iPhone4Storyboard = [UIStoryboard storyboardWithName:@"Main4s" bundle:nil];
UIViewController *initialViewController = [iPhone4Storyboard instantiateInitialViewController];
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
self.window.rootViewController = initialViewController;
self.myViewController = (ViewController *)_navigationController.topViewController;
self.myViewController.managedObjectContext = self.managedObjectContext;
[self.window makeKeyAndVisible];
}
