ios - 正确关闭新的 ViewController 页面

Question

请帮助我关闭 ViewController。我用这段代码打开新的 ViewController(“SettingsPage”):

settingClass = storyboard?.instantiateViewControllerWithIdentifier("SettingsPage") as! SettingsClass
settingClass.modalPresentationStyle = .OverFullScreen
settingClass.modalTransitionStyle = .CrossDissolve
self.presentViewController(settingClass, animated: true, completion: nil)

然后我需要返回(关闭 SettingsPage)，当我使用这个方法时我会得到双倍的 MainView

mainClass = storyboard?.instantiateViewControllerWithIdentifier("MainView") as! ViewController
mainClass.modalTransitionStyle = .CrossDissolve
self.presentViewController(mainClass, animated: true, completion: nil)

如何正确关闭新的 ViewController(“SettingsPage”)女巫像 .OverFullScreen 一样打开，然后返回到我的 MainView？

Answer 1

尝试像这样关闭它

mainClass.dismissViewControllerAnimated(true, completion: {});
