I have working iOS application
In order to support iOS8
, I am replacing UIAlertView/UIActionSheet with
UIAlertController
.
Problem :
For display UIAlertController I need presentViewController
method of UIViewController class.
But UIAlertView is display from classes which are inherited
from
UIView or NSObject
,
I can not get [self presentViewController...]
method for obvious reason.
My Work :
I tried getting rootViewController form current window and display UIAlertController.
[[[UIApplication sharedApplication] keyWindow].rootViewController presentViewController ...]
but have some rotation problems like if my current view controller do not have rotation support it will rotate if UIAlertController is open.
Question :
Did any one faced same problem and have safe solution ?
if yes please provide me some example or give some guide
I solved an essentially similar problem today. Like Jageen, I ran into a situation where I wanted to present a UIAlertController but from a non-UIViewController class. In my case, I wanted an alert to pop up when the failure block of a HTTP request is run.
This is what I used and unlike our friend here, it worked quite perfectly for me.
UIApplication.sharedApplication().keyWindow?.rootViewController?.presentViewController(errorAlert, animated: true, completion: nil)
