Called by the devil

Wednesday, November 5th, 2008

OMG! Take a look who just called me!!! Unfortunately I was already in a call with the number “0″ here in Germany, as you can see. I feel really important now :)

I have honestly no idea what was going on there. I guess either the caller with “+49 0″ was somehow scrambling the caller-id or the callerd-id display of T-Mobile was fucked at the moment. It was a call from a german TV station, btw. :)

How to have your iPhone Application removed from Apple’s AppStore

Friday, August 29th, 2008

Apple offers a semi-automated way to publish your iPhone applications to the AppStore. But the frontend only offers the possibility to add new or update applications. What if you want to pull your applications from the AppStore? Probably an old application doesn’t meet your own quality standards any more or you want to prevent elgal issues. While Apple is known to have removed several applications from the store (remember the 1000$ app? :) ), it’s not obvious to developers how to remove your own app.

Log in to your account at http://itunesconnect.apple.com

  1. Select “Manage Your Apps”
  2. Select the desired application
  3. Select “Edit Information”
  4. Select the “Pricing” tab
  5. Uncheck all territory clearance
  6. Save your changes

This is actually the way suggested by Apple’s helpdesk! Looks good enough for me.

Getting “symbol(s) not found” when building your iPhone application

Saturday, August 16th, 2008

I just wasted like 30 minutes having a major WTF-experience. I was getting “symbol(s) not found” errors when compiling my iPhone application for calls to CoreGraphics objects. What you have to do is add the CoreGraphics.framework to your application. Easy, hu? Not so easy! There are two different CoreGraphics.frameworks and adding the one which is used for the real world iPhone wont compile (or rather link, as linking is where the error occurs) for the iPhone simulator! So make sure you have added the right framework. For the real iPhone it should be located at
/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS2.0.sdk/System/Library/Frameworks/CoreGraphics.framework

Happy compiling!

Disable the iPhone auto screen-lock by API

Thursday, August 14th, 2008

If you are developing iPhone applications you might run into a situation where your application is “closed” by the iPhone’s automatic screen lock, which kicks in after a few minutes, according to the settings by the user. This of course happens when you have no interaction like tapping the screen from the user.
To disable the automatic screen lock you have to add the following line of code to the applicationDidFinishLaunching method of your app delegate.

application.idleTimerDisabled = TRUE;

iPhone 3G Keyboard Lag

Tuesday, July 15th, 2008

The keyboard input of my iPhone 3G is really slow at the moment. Check the video to see what I mean. The keyboard seems to have a lag and only types like 1 character every 1/2 second. This only concerns mail, writing SMS works just fine. Think I got to reboot the frigging thing once again…

Update Installing the 2.0.1 Update from Apple for the iPhone should fix this error!

iPhone 3G Akku besser als sein Ruf

Tuesday, July 15th, 2008

Die amerikanische Zeitschrift  PC WORLD hat jetzt die oft kritisierte Batterielaufzeit des iPhone 3G getestet und mit den wichtigsten Telefonen des Wettbewerbs verglichen. Dabei ist erstaunlich, dass das iPhone nicht nur eine längere Laufzeit als alle Mitbewerber hatte, sondern selbst die von Apple versprochene Sprechzeit von 5 Stunden um 38 Minunten übertrifft.

Batterielaufzeit des iPhone 3G verbessern
Aufgrund des höheren Strombedarfs des UMTS Netzes liegt die Batterielaufzeit natürlich unter der des klassischen iPhones. Mit einem Trick lässt sich allerdings die Laufzeit des iPhone 3G weiter erhöhen. Dazu muss man einfach die 3G Funktion abschalten. Man verliert dabei zwar den hohen Datenduchsatz des UMTS Netzes bei der Datenübertragung aber dafür hält die Batterie des iPhone 3G länger.

Dazu kann man unter Einstellungen -> Allgemein -> Netzwerk den Schalter “3G aktivieren” abschalten. Danach sollte sich die Batterielaufzeit ein wenig verlängern.

Bluetooth iPhone 3G im BMW Z4

Friday, July 11th, 2008

Zumindest die kleineren T-Punkte in München Pasing und Laim waren seeeeeeehr dünn mit Geräten bestückt. Zum Glücl hat Laim erst eine halbe Stunde später geöffnet, denn in Pasing gab es nur für die ersten 3 Leute eins. Ich war dann der erste in der Reihe und hab eins der beiden freien Geräte in Laim bekommen. 16GB in Schwarz, genauso wie ich es wollte. Es kamen bestimmt noch 5 Leute in den Laden, die ganz locker ein iPhone 3G verlangt haben und dann unverrichteter Dinge wieder abziehen mussten.

Das beste ist: Sogar die Bluetooth Kopplung im BMW funktioniert.

Ideal ist die Befestigung des iPhone in einer Autohalterung.
