  • 0

I have an already running iphone app with target OS 3.1. I am trying to transform it into a universal app.
I am not going to change the model, only the xib.
So I wrote the ipad xib in IB, then I went to info.plist and add MainIpad Nib for ipad pointing to a proper MainIpad.xib.
I also set Target Device Family in project info to ipad/iphone.

That seems to be not enough, whenever I run ipad simulator, I always get the MainIpad.xib view resized as iphone, actually it’s just showing an iphone inside an ipad. I also tried to set the CGRect manually to the ipad size. The result is a bigger view still clipped into an iphone.

Can you point out what I am doing wrong and suggest the proper way to convert in universal app ?

thanks

    Can you point out what I am doing
    wrong and suggest the proper way to
    convert in universal app ?

    The proper way? That’s easy. From page 20 of the iPad Programming Guide:

    Important: You should always use the
    Upgrade Current Target for iPad
    command to migrate existing projects.
    Do not try to migrate files manually.

    By your problem description, it looks like you tried to migrate the files manually.

    My advice to you is: start over using a copy of your project before you started the migration. (You did save a copy of the project before you started the conversion, like a good programmer should do, right?)
