UIAlertView/UIAlertController iOS 7 and iOS 8 compatibility

Question

I am using Swift to write an app and I need to show an alert. The app must be iOS 7 and iOS 8 compatible. Since UIAlertView has been replaced with UIAlert

Answer 1

Here is my drag and drop swift solution:

//Alerts change in iOS8, this method is to cover iOS7 devices
func CozAlert(title: String, message: String, action: String, sender: UIViewController){

    if respondsToSelector("UIAlertController"){
        var alert = UIAlertController(title: title, message: message, preferredStyle: UIAlertControllerStyle.Alert)
        alert.addAction(UIAlertAction(title: action, style: UIAlertActionStyle.Default, handler:nil))
        sender.presentViewController(alert, animated: true, completion: nil)
    }
    else {
        var alert = UIAlertView(title: title, message: message, delegate: sender, cancelButtonTitle:action)
        alert.show()
    }
}

Call like this:

CozAlert("reportTitle", message: "reportText", action: "reportButton", sender: self)

Beware this is only for the most basic alerts, you might need additional code for advanced stuff.

Answer 2

download alert class from this link and use it easily for ios 6 ,7 and 8

//Old code  
**UIAlertView** *alert=[[**UIAlertView** alloc]initWithTitle:@"FreeWare" message:@"Welcome to Common class" delegate:self cancelButtonTitle:@"Cancel" otherButtonTitles:@"Ok", nil];

//New code 

**MyAlertView** *alert=[[**MyAlertView** alloc]initWithTitle:@"FreeWare" message:@"Welcome to Common class" delegate:self cancelButtonTitle:@"Cancel" otherButtonTitles:@"Ok", nil];
