monotouch iphone以编程方式进入手机主屏幕

Question

I searched a lot and didn't find how to programmatically bring application to background so phone's home screen is shown. I don't want to terminate app, but just to programmatically make press on HOME button. Is there any way to do it?

Answer 1

Unfortunately, there is no background mode in iOS where the app can still run things while out of focus. Apple has designed the system to "pause" the application so state is preserved, but be careful the app can be terminated at any time.

Answer 2

No, unfortunately not. There is no public API that allows you to send a user back to the homescreen.

As shown in these questions:

• iPhone - Sending the app to the background
• Send App to Background process
• Sending Application to background on iphone
• Programmatically sending an iOS app to background

Brad Larson provides a detailed explanation to the answer of this question:

• Suspend the application

Answer 3

You can do this by calling a private API but beware as said above Apple does not allow this on AppStore apps.

var x = UIApplication.SharedApplication;
x.PerformSelector (sel: new MonoTouch.ObjCRuntime.Selector ("suspend"), obj: x, delay: 5);
