我是Xcode和Objective-C的新手，我为这个noob问题道歉，但我需要帮助。我正在使用故事板，并有第二个视图控制器用于设置和游戏屏幕。这似乎在IOS 8及更高版本中正常工作，但在执行此代码时，应用程序仅在IOS 7.1.2中关闭。
// This View Controller will provide a means of checking Game Center standings/ achievements
- (IBAction)settingsVC:(id)sender {
IOSSettingsViewController *vc = [self.storyboard instantiateViewControllerWithIdentifier:@"IOSSettingsViewController"];
vc.alphaFromVC1 = [NSNumber numberWithFloat:0.0];
[self presentViewController:vc animated:YES completion:nil];
// RESET the START BUTTON
[self.startButton setEnabled:YES];
return;
}
应用程序关闭而不启动第二个（设置）视图控制器。任何人都可以提出什么问题？它再次在IOS 8中运行良好。非常感谢你指引我朝着正确的方向前进。
以下是我的一位测试人员的崩溃日志。
