Play local notification default sound when displaying UIAlertView?



I'm writing a reminders app for iPhone that displays reminders using local notifications.





If a reminder goes off while the application is running, the local notification isn't displayed. Instead, the didReceiveLocalNotification method is called in my app delegate, and I mimic the local notification dialog by displaying a UIAlertView with the reminder text.





When local notifications are displayed outside of the app, the device vibrates and the sound specified by UILocalNotificationDefaultSoundName is played. Again, I'd like to mimic this in the app when displaying the UIAlertView .





I can vibrate the device by calling AudioServicesPlaySystemSound(kSystemSoundID_Vibrate) , but I can't figure out how to play the local notification default sound. There's no equivalent SystemSoundID constant, and I'm not sure what the path would be.





tl;dr I'd like to play the local notification default sound when displaying a UIAlertView. Any ideas?

  1. Good question. Ideally, there would be a way of selecting a system sound using AudioServices. However, the following statement from Apple's "System Sound Services Reference" suggests otherwise:


    In Mac OS X, when a user has
    configured System Preferences to flash
    the screen for alerts, or if sound
    cannot be rendered, calling this
    function will result in the screen
    flashing. In Mac OS X, pass the
    constant
    kSystemSoundID_UserPreferredAlert to
    play the alert sound selected by the
    user in System Preferences. In iOS
    there is no preferred user alert
    sound.


    Since it seems like the SDK has little to offer, you might wish to mimick the system sounds by using your own wav file. There is a nice library at the following link, perhaps it will have the sound you're looking for: http://sites.google.com/site/iphonesounds/iPhoneOriginalSystemSounds_WAV.zip

    Good luck!

div not scrolling properly with slimScroll plugin

I am using the slimScroll plugin for jQuery by Piotr Rochala Which is a great plugin for nice scrollbars on most browsers but I am stuck because I am using it for a chat box and whenever the user appends new text to the boxit does scroll using the .scrollTop() method however the plugin's scrollbar doesnt scroll with it and when the user wants to look though the chat history it will start scrolling from near the top. I have made a quick demo of my situation http://jsfiddle.net/DY9CT/2/ Does anyone know how to solve this problem?

Why does this javascript based printing cause Safari to refresh the page?

The page I am working on has a javascript function executed to print parts of the page. For some reason, printing in Safari, causes the window to somehow update. I say somehow, because it does not really refresh as in reload the page, but rather it starts the "rendering" of the page from start, i.e. scroll to top, flash animations start from 0, and so forth. The effect is reproduced by this fiddle: http://jsfiddle.net/fYmnB/ Clicking the print button and finishing or cancelling a print in Safari causes the screen to "go white" for a sec, which in my real website manifests itself as something "like" a reload. While running print button with, let's say, Firefox, just opens and closes the print dialogue without affecting the fiddle page in any way. Is there something with my way of calling the browsers print method that causes this, or how can it be explained - and preferably, avoided? P.S.: On my real site the same occurs with Chrome. In the ex
