How to link with framework without arm64 support i

问题:

After upgraded a project on Xcode 5.1, Product > Build gives the following warning and error:

ld: warning: ignoring file Dropbox/Dropbox.framework/Dropbox, missing required architecture arm64 in file Dropbox.framework/Dropbox (3 slices)

Undefined symbols for architecture arm64: "_OBJC_CLASS_$_DBPath", referenced from: objc-class-ref in DropboxViewController.o

It seems like the Dropbox.framework does not support arm64 yet.

What are the Xcode settings to remove arm64 support from the project to have a clean build?

回答1:

Change:

• Architectures: Standard
• Valid Architectures: arm64 armv7 armv7s

To:

• Architectures: armv7 armv7s
• Valid Architectures: armv7 armv7s

回答2:

Remove armv64 in

Project > Build Settings > Architectures> Valid Architectures

( i.e. leave only armv7 and armv7s )

Also, set Build Active Architectures Only to NO.
