Messed Up Icons With iPhone OS 3.0 Beta 5

With the latest release of iPhone OS 3.0 seed 5, the icons of the applications are being messed up. This mostly occurs when we install updates to the applications from App store. Few applications will not have any icons altogether, few apps have icons of their neighbouring apps like shown in the figure. iPhone OS 3.0 beta 5 is lot more buggier than beta 4 or beta 3. Also I have observed beta 5 drains the battery very fast. My iPhone lost more than half of its power over night even without performing any tasks while lying idle. Seems Apple has purposefully made beta 5 buggy so that users are forced to move to the final version expected in the WWDC.

On the screenshot we can observe that, PingPongLite application doesnt have icon at all and NewsPro and Bloomberg have same icons.

However on a positive note, if we restart the iPhone, all icons are restored to their original application icons.

Update:

The messed up icons issue has been fixed with the latest iPhone OS 3.0 GM build. Also with the GM build my iPhone runs relatively for a longer duration on a full battery charge than what I used to get with beta 5. (But still I feel 3.0 is consuming too much of battery than 2.2.1)

iPhone OS Active SDK Targets Missing

The iPhone SDK 3.0 is great in offering tons of new features to developers to play with. It irresistable not to install it n use it. But we should be ready to make few sacrifices in using it. Firstly as the release notes says, iPhone OS 3.0 beta installed on iPhone can’t be revereted back to a earlier version of OS. While this was a big issue for people who skipped reading the release notes n were excited to install iPhone OS 3.0 Seed 1. However the later versions of iPhone OS 3.0 Seed 3 and 4 seem to be pretty stable and near production quality expect for few problems like low battery backup. The other major issue I am facing with iPhone SDK 3.0 is not being able to set the Active Target to a earlier version of iPhone OS other than 3.0. XCode silently removes all the other available options from the ‘Active SDK’ list and gives only iPhone OS 3.0. This can be annoying, but we cant blame Apple for this as they have warned this in their release notes. The image on the left shows the behaviour I am talking about.

Remove User Specific Files From XCode Project File

But as the saying ‘Where there is a will, there is way’, we can overcome this by following these steps:-

1. Clean All Targets
2. Close the project
3. Right click on your XCode project file and select ‘Show Package Contents’
4. You will be presented with usually 3 files with two of the files carrying the system user name as shown in the figure. Delete those two files. (Don’t worry, Its safe to remove them.) And open your project again and you should be able to see the old SDK options back in your ‘Active SDK’ list

Active SDK Regained

For now I am setting GDATA_SKIP_LOG_XMLFORMAT = 1 for my project to compile without any error.
