通話故事板的場景從應用委託

Question

我想打電話給一個故事板的場景從的appDelegate [storyboard ID : MyScene]，

我已經搜查，並試圖對堆棧溢出考慮到許多答案！但找不到工作解決方案。

一個我試過的代碼，

UIStoryboard *mainStoryboard = [UIStoryboard storyboardWithName:@"Main" bundle: nil]; 
UIViewController *sc= (UIViewController *)[mainStoryboard instantiateViewControllerWithIdentifier:@"MyScene"]; 

[self.window.rootViewController presentViewController:sc animated:YES completion:nil]; 

Answer 1

嘗試使用調用此代碼一些延遲。

dispatch_after(dispatch_time(DISPATCH_TIME_NOW, 1 * NSEC_PER_SEC), dispatch_get_main_queue(), ^{ 

// Your code for presenting 

UIStoryboard *mainStoryboard = [UIStoryboard storyboardWithName:@"Main" bundle: nil]; 
UIViewController *sc= (UIViewController *)[mainStoryboard instantiateViewControllerWithIdentifier:@"MyScene"]; 

[self.window.rootViewController presentViewController:sc animated:YES completion:nil]; 

});
