    Is it the space between imgData and .date ?

    Study the source and documentation for ImageData and ImagePicker in order to debug this. Questions that you might want to ask include:

    • Are you sure that the crash is at the assignment of date?
    • Is the block parameter "date" initialized? And if not, why not?
    • What data-type is the ImageData date property?

    Good luck :)

    It might also be helpful to put a breakpoint inside the handler and step through it. This should tell you which line is causing the EXC_BAD_ACCESS.

    Sending a message to a released object is the most common cause of EXC_BAD_ACCESS. I suspect the problem is with either arrayForObjects or imagesTable.

    Setting a property incorrectly or passing an invalid parameter is more likely to thrown an exception.
