问题 how can i close or minimize my app from code like when i push home button? 回答1: exit(0); will close your app. Its not recommended though. 回答2: You don't have to do anything, it'll be done by the framework 回答3: To minimize your app using an approved API, launch another app, for instance Safari, using a registered URL. 回答4: You can use exit(0) but your application will be rejected if you submit it to the App Store.

Is there something about that flipside/mainview template that makes it difficult or impossible to send data from Mainview to Flipside? 回答1: In the Utility Template, the MainViewController (the view controller for the front side) creates the
