Would there be any issue with creating an app that contains multiple Today
Widgets? I've actually done it, and it works on the simulator and on my phone.
But now with XC6, I can't build an archive so I am wondering if it is related
to the .IPA build problem, or Apple won't allow multiple widgets
We're having a hard time building an IPA file in XC6. From what I have read
online, it seems to be a bug. We can make a .pkg file or an XCarchive file from
our app. Any confirmation this really is a bug? Seems really unusual for such
an important feature. We have already tried to add the LSRequi
ng my item# together and
multiply n wouldn't give a real offset to a bit in a bitmap.
