I just migrated to the new iPhone6 and recognized, that I’m not able to send out any emails from different apps like the Apple Mail app or within third party apps.
After reinstalling from iCloud-backup I go all my previously installed pop/smtp-mail accounts. When I opened Apple Mail the first time it prompted me for all the POP-passwords, to access the email-accounts. So far so good. I thought everything is ok and setup now.
But I encountered a bug, as I tried to send a picture with the Apple Picture App via email. It looked like I did successfully send out the picture. But it never arrived. So I tried to figure out the problem and a workaround. I found the bug, reported it to the Apple bug reporter but I wanted to share the easy workaround:
Just open the Apple Mail app and send one first test-email from every pop/smtp-account … then you’ll get prompted for the missing smpt-password. After entering the right password the test-emails will be send out. Even the stuck emails, which could not be delivered before, will now be sent out. Just check out the “Sent” box by selecting the email-Account in the account list of the Mail app. If the old mails are still here. you need to open and send them to get everything done.

Hope this helps :-)

iOS application icon naming conventions

A short reminder on how to name your iPhone / iPad app icons properly. Sure, you can always specify those names specificy in the application info.plist. But why not chose convention over configuration to make life easier ;-)

Icon.png (required)
# 57x57px ... standard iPhone icon
Icon@2x.png (required)
# 114x114px ... retina display iPhone icon
Icon-72.png (required)
# 72x72px ... standard iPad icon
Icon-Small.png (recommended)
# 29x29px ... standard iPhone Spotlight search icon
Icon-Small@2x.png (recommended)
# 58x58px ... retina display iPhone Spotlight search icon
Icon-Small-50.png (recommended)
# 50x50px ... standard iPad Spotlight search icon

Just drag the files into the “Supporting Files folder” within Xcode and allow Xcode to copy the files into the proper directory of your app.
If you also want to adhoc distribute your app – like, in beta testing – you should also include the following iTunesArtwork-file in your source. If you want it to render with the shiny Apple effects in iTunes you need to provide a JPEG file, if it should be rendered untouched just use a PNG. The iTunesArtwork file must not have a file extention:

iTunesArtwork
# 512x521px ... iTunes icon used with adhoc distributions

And don’t forget to exclude the file in your iTunes-Connect distributions to the AppStore. There you upload the PNG file separately within the upload process in iTunesConnect!

Hope this saves some time ;-)


Thank you for so much, Steve.

I was deeply moved by Your commencement speech in Stanford as I am when I watch it today …


Sure, it’s not Steve Jobs presenting on this special event … but I think the mixture of Tim Cook, Scott Forstall, Eddy Cue and Phil Schiller giving the presentation works out quite well. But see it for yourself by watching the official video-stream from Apple about the iOS 5, iCould, iPhone 4s, Siri & all the other details.

P.S. Hope Steve Jobs health recovers!


Here’s the Quicktime video stream of this years WWDC 2011 keynote about Mac OS X Lion, iOS 5 and iCloud … and how it all works together. So, tune in to see Steve Jobs, Phil Schiller and Scott Forstall presenting the newest software developments.
