Several UIAlertViews for a delegate

由 别来无恙 提交于 2019-11-27 10:45:10
问题 Currently I've got a class popping up UIAlertView s here and there. Currently, the same class is the delegate for these (it's very logical that it would be). Unfortunately, these UIAlertView s will call the same delegate methods of the class. Now, the question is - how do you know from which alert view a delegate method is invoked? I was thinking of just checking the title of the alert view, but that isn't so elegant. What's the most elegant way to handle several UIAlertView s? 回答1: Tag the

Dismissing UIAlertViews when entering background state

由 倾然丶 夕夏残阳落幕 提交于 2019-11-27 10:30:24
Apple recommends dismissing any UIAlertViews/UIActionSheets when entering background state in iOS 4. This is to avoid any confusion on the user's part when he relaunches the application later. I wonder how I could elegantly dismiss all UIAlertViews at once, without retaining a reference to it everytime I set one up... Any idea ? Guillaume I was intrigued by Dad's answer (funny username :), and curious why it was down-voted. So I tried it. Here is the .m part of a subclass of UIAlertView. Edit: (Cédric) I have added a way to catch calls to delegate methods and remove the observer then to avoid

How to add an action to a UIAlertView button using Swift iOS

由 谁说我不能喝 提交于 2019-11-27 10:19:23
问题 I want to add another button other than the "OK" button which should just dismiss the alert.

由 无人久伴 提交于 2019-11-27 10:18:00

iOS - Push notification alert is not shown when the app is running

由 荒凉一梦 提交于 2019-11-27 09:26:07
问题 I've integrated push notifications in my app. Users will receive push notification to join a group. When the user clicks Join , I've to handle something in the code. And so I'm implementing: - (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo This is working fine when the app is not running. When the app is running, I don't see any UIAlertView . How can make my app show the push notification alert so that user can still decide whether to join

Get the top ViewController in iOS Swift

由 99封情书 提交于 2019-11-27 09:18:29
I want to implement a separate ErrorHandler class, which displays error messages on certain events. The behavior of this class should be called from different other classes. When an error occurs, it will have an UIAlertView as output. The display of this AlertView should ALWAYS be on top. So no matter from where the Error gets thrown, the topmost viewController should display the AlertMessage (e.g. when an asynchronous background process fails, I want an error message, no matter what View is displayed in the foreground). I have found several gists which seem to solve my problem (see the code

wait_fences: failed to receive reply: 10004003 error - UIAlert WITHOUT UITextField present

由 风格不统一 提交于 2019-11-27 08:45:41
I am working on an app where a UIAlert pops up the first time the user begins using it to ask if they want to use their current location. This happens within the main controller. However, I get the following error when using the UIAlert: wait_fences: failed to receive reply: 10004003 I debugged it, and googled around. I am not using a textarea or keyboard input, so I don't have to resign a first responder. However, I still cannot figure out why I would be getting this error. It only appears when I add the UIAlert. MainController.m - (void)viewDidLoad { UIAlertView *mainAlert = [[UIAlertView
