ios - App crashes when InApp mail command gets called

Question

When I cll the Message Compose sheet via a UIActionSheet button I get the following error. Sorry these don't mean much to me yet - still learning:-)

Could anyone help please?

These are the sources of problems that come up.

This is in the log:

2012-06-16 19:10:43.437 Multi Web[2665:4013] XPCProxy received bad message: target did not supply method signature for bodyFinishedDrawing 2012-06-16 19:10:43.489 Multi Web[2665:907] _serviceViewControllerReady:error: Error Domain=XPCObjectsErrorDomain Code=3 "The operation couldn’t be completed.

Some code will be helpful for us. – Juniejunieta

Hi, I added the whole method, I hope its helpfull – Plastid

// Remove the mail view [self dismissModalViewControllerAnimated:YES]; Remove this line and try againbecause mail view is still not loaded so which modal view you are dismissing – Polynuclear

@Polynuclear Thanks that did the trick:-) Funny leaving that line worked in another project - The only difference is that I am calling it through an actionSheet this time. Strange:-) – Plastid

Answer 1

The correct answer is to remove the

[self dismissModalViewControllerAnimated:YES] 

just after the presentModalViewController method.

You are crashing because, you dismiss the modal view controller soon after it is presented and try to dismiss it again (which is deallocated already) in the callback delegate.
