正确关闭新 ViewController 页面

Question

请帮助我结束 ViewController。 我用这个代码打开新的 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），当我使用此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") 打开像 .OverFullScreen，然后返回到我的 MainView？

Answer 1

试试这样关闭

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