We have a project that runs fine on OS4 but we’re having problems getting it to run on iPad 3.2.

Base SDK is 4.0 and Deployment target is 3.2.

The code crashes on the iPad simulator (and device) before it has even started, with the error

“Data Formatters temporarily
unavailable”

It seems to run okay if I take 2 lines out…

AVURLAsset* asset = [AVURLAsset URLAssetWithURL:assetURL options:options];

and

export = [[AVAssetExportSession alloc] initWithAsset:asset presetName:AVAssetExportPresetPassthrough];

I branch according to what OS is present so that these lines never get reached when on a 3.2 device (I know they are OS4), but just them being there at all makes the thing crash out before it even begins.

Any ideas?
Cheers

    If those lines are never reached on the iPad, you may be encountering a problem due to not weak-linking the AVFoundation framework (and potentially others). Because AVURLAsset and AVAssetExportSession don’t exist as symbols in 3.2, your application may be crashing on startup on that older OS.

    I describe how to weak-link a framework in response to a similar problem in this answer.
