Update: As of iOS 9 SDK, UIActionSheet is deprecated, so do not expect a fix regarding this issue. It is best to start using UIAlertController when possible. The problem seems to come from Apple’s switch to using UIAlertController internally to implement the functionality of alert views and action sheets. The issue is seen mostly on … Read more
You have to step some views deeper: let subview = actionController.view.subviews.first! as UIView let alertContentView = subview.subviews.first! as UIView alertContentView.backgroundColor = UIColor.blackColor() And maybe you want to keep original corner radius: alertContentView.layer.cornerRadius = 5; Sorry for the “Swifting” but i’m not familiar with Objective-C. I hope that’s similar. Of course it’s also important to change … Read more
EDIT: Updated for Swift 5 EDIT: Updated to include @skywalker’s feedback So I actually got this to work. In short, it involves adding a long-press gesture recognizer to the UIAlertController that triggers before the dismissal occurs. First, create lazily loaded computed variables in your view controller for your UIAlertController and the UIAlertAction you want to … Read more
try this Objective-C UIWindow* topWindow = [[UIWindow alloc] initWithFrame:[UIScreen mainScreen].bounds]; topWindow.rootViewController = [UIViewController new]; topWindow.windowLevel = UIWindowLevelAlert + 1; UIAlertController* alert = [UIAlertController alertControllerWithTitle:@”APNS” message:@”received Notification” preferredStyle:UIAlertControllerStyleAlert]; [alert addAction:[UIAlertAction actionWithTitle:NSLocalizedString(@”OK”,@”confirm”) style:UIAlertActionStyleCancel handler:^(UIAlertAction * _Nonnull action) { // continue your work // important to hide the window after work completed. // this also keeps a reference … Read more
The detection pattern is identical to the Objective-C style. You need to detect whether the current active runtime has the ability to instantiate this class if objc_getClass(“UIAlertController”) != nil { println(“UIAlertController can be instantiated”) //make and use a UIAlertController } else { println(“UIAlertController can NOT be instantiated”) //make and use a UIAlertView } Don’t try … Read more
Instead of self in your handler, put (alert: UIAlertAction!). This should make your code look like this alert.addAction(UIAlertAction(title: “Okay”, style: UIAlertActionStyle.Default, handler: {(alert: UIAlertAction!) in println(“Foo”)})) this is the proper way to define handlers in Swift. As Brian pointed out below, there are also easier ways to define these handlers. Using his methods is discussed … Read more
From iOS8 Apple provide new UIAlertController class which you can use instead of UIAlertView which is now deprecated, it is also stated in deprecation message: UIAlertView is deprecated. Use UIAlertController with a preferredStyle of UIAlertControllerStyleAlert instead So you should use something like this UIAlertController * alert = [UIAlertController alertControllerWithTitle:@”Title” message:@”Message” preferredStyle:UIAlertControllerStyleAlert]; UIAlertAction* yesButton = [UIAlertAction … Read more
You’re correct: if the user can tap a button in your alert, the alert will be dismissed. So you want to prevent the user from tapping the button! It’s all just a matter of disabling your UIAlertAction buttons. If an alert action is disabled, the user can’t tap it to dismiss. To combine this with … Read more
You can present a UIAlertController from a popover by using UIPopoverPresentationController. In Obj-C: UIViewController *self; // code assumes you’re in a view controller UIButton *button; // the button you want to show the popup sheet from UIAlertController *alertController; UIAlertAction *destroyAction; UIAlertAction *otherAction; alertController = [UIAlertController alertControllerWithTitle:nil message:nil preferredStyle:UIAlertControllerStyleActionSheet]; destroyAction = [UIAlertAction actionWithTitle:@”Remove All Data” style:UIAlertActionStyleDestructive … Read more
UIAlertController extends UIViewController, which has a view property. You can add subviews to that view to your heart’s desire. The only trouble is sizing the alert controller properly. You could do something like this, but this could easily break the next time Apple adjusts the design of UIAlertController. Swift 3 let alertController = UIAlertController(title: “\n\n\n\n\n\n”, … Read more
