button.onclick trigger twice on ios device

Forgive my poor english……
I have found a strange problem, as the title said up.
The problem happened when the "applicationWillResignActive" method was triggered in "onclick" callback, example:

Code (CSharp):

1.  
2. public void OnButtonClick()
3. {
4.     Debug.Log("Button Click!");
5. }
6.  

now it is fine, when i click the button, the log print once. then i changed it to

Code (CSharp):

1.  
2. public void OnButtonClick()
3. {
4.     Debug.Log("Button Click!");
5.     Application.OpenURL("[URL]http://www.google.com[/URL]");
6. }
7.  

the new code is just to let the system method "applicationWillResignActive" triggered. But now, the output log will print twice, looks like:


Button Click!
……(the stack info)
-> applicationWillResignActive()
ButtonClick!
……(the stack info)
-> applicationDidEnterBackground()


i have tried some different methods to trigger "applicationWillResignActive", and they also have the same problem.

Can someone please help me?
my unity version is 4.6.9f1.

 

I met it too. Can somebody help me?

 

hi povilas:
thanks for your reply. as your suggest, i have tried the same code on version 5.3.4p6, and the problem disappeared. so it may be a bug on 4.x.
