uialertcontroller

In previous versions of iOS I was able to call show on a UIAlertView in the App Delegate. More specifically, show was called in: func applicationDidBecomeActive(application: UIApplication) Since UIAlertView s disregarded the view hierarchy in most cases, this solution worked no matter where the user was in the app. With the introduction of UIAlertController this problem becomes a little trickier. UIAlertController is now a subclass of UIViewController and needs to be presented just like any other UIViewController. While presenting the UIAlertController from the keyWindow's rootViewController

I created a popup alert using alert controller and added two alert actions(ok and cancel) as below. UIAlertController * alert= [UIAlertController alertControllerWithTitle:@"Cycling" message:@"Please enter title and description" preferredStyle:UIAlertControllerStyleAlert]; UIAlertAction* ok = [UIAlertAction actionWithTitle:@"OK" style:UIAlertActionStyleDefault handler:^(UIAlertAction * action) { [alert dismissViewControllerAnimated:YES completion:nil]; }]; UIAlertAction* cancel = [UIAlertAction actionWithTitle:@"Cancel" style:UIAlertActionStyleDefault handler:^(UIAlertAction * action) { [alert

I want to conform to the UIAlertController used in iOS 8 since UIAlertView is now deprecated. Is there a way that I can use this without breaking support for iOS 7? Is there some kind of if condition I can do to check for iOS 8 otherwise do something else for iOS 7 support? Please see the answer of Erwan (below my answer) as I see it is the best. -- You can check the iOS version to use appropriate control like this: if (([[[UIDevice currentDevice] systemVersion] compare:@"8.0" options:NSNumericSearch] == NSOrderedAscending)) { // use UIAlertView } else { // use UIAlertController } I think a

Apple has deprecated the action sheet in iOS 8.3 how do you add an action sheet to my user interface? I realized Apple's documentation isn't very clear on how to create an action sheet with UIAlertController. So after a little playing around I just wanted to share my code, since I couldn't really find anything useful on Stack Exchange about this topic. I had the same problem in my iPhone app, with an UIActionSheet to ask the user if they wanted to take a photo, or pick an image from their gallery. Prior to iOS 9, the following code worked fine: UIActionSheet *actionSheet = [[UIActionSheet

I am using a UIAlertController to present a dialog with a UITextField and one UIAlertAction button labeled "Ok". How do I disable the button until a number of characters (say 5 characters) are input into the UITextField ? Add following property in your header file @property(nonatomic, strong)UIAlertAction *okAction; then copy the following code in your viewDidLoad method of your ViewController self.okAction = [UIAlertAction actionWithTitle:@"OK" style:UIAlertActionStyleDefault handler:nil]; self.okAction.enabled = NO; UIAlertController *controller = [UIAlertController alertControllerWithTitle

I created an UIAlertController let alertC = UIAlertController(title: "Title", message: "Message", preferredStyle: UIAlertControllerStyle.Alert) alertC.addTextFieldWithConfigurationHandler(addTextField) alertC.addAction(UIAlertAction(title: "Cancel", style: UIAlertActionStyle.Default, handler: nil)) alertC.addAction(UIAlertAction(title: "OK", style: UIAlertActionStyle.Default, handler: okButton)) presentViewController(alertC, animated: true, completion: nil) But after that I would like to change the UIAlertController height? How can I do this? Barrett I found you can add constraints before you

I'm trying to create uialertcontroller in Config.swift file as follow. static func showAlertMessage(titleStr:String, messageStr:String) -> Void { let window : UIWindow? let alert = UIAlertController(title: titleStr, message: messageStr, preferredStyle: UIAlertControllerStyle.Alert); self.window!.presentViewController(alert, animated: true, completion: nil) } problem is I've found problem in self.window!. Type 'Config' has no member 'window' Please let me know how to solve that issue. self.window would mean that there's a window object in this class, and it's not the case. You would need to use

I am using Xcode 6 to develop an iOS Application. When I used UIAlertController , it can be worked well on iPhone 6 simulator, but crashes on iPad simulator. My problem while clicking "share", then it could be crashed. How could I solve it? Here is my Code: override func tableView(tableView: UITableView, editActionsForRowAtIndexPath indexPath: NSIndexPath) -> [AnyObject] { var shareAction = UITableViewRowAction(style: UITableViewRowActionStyle.Default, title: "Share", handler: { (action:UITableViewRowAction!, indexPath:NSIndexPath!) -> Void in let shareMenu = UIAlertController(title: nil,
