iPhone Simulator vs iPhone OS testing: file is not of required architecture

i'm working on an iphone app ( sdk 3.1.3 ) and I have added the corelocation and mapkit framework. I used the iphonesimulator package, but added them using 'relative to current sdk'. When I test my app in the iphone simulatore everything works. But when I switch to iphone device 3.1.3 i'm getting 2 warnings and 4 build 开发者_开发知识库errors:

warnings:

.../corelocation file is not of required architecture

.../mapkit file is not of required architecture

errors:

I right-clicked on the mapkit framework package, checked get info and the path is set as: System/Library/Frameworks/MapKit.framework

I have basic iphone dev knowledge, but i don't know what the problem is... Can anyone help me out?

I too have same problem, I've resolved it by adding CoreLocation.framework inside the Frameworks folder.

In that get info window, check the "full path" of the MapKit.framework package, then in a Terminal window use the "file" command to verify what architecture the library is. Should see something like:

file /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS3.1.2.sdk/System/Library/Frameworks/MapKit.framework/MapKit
/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS3.1.2.sdk/System/Library/Frameworks/MapKit.framework/MapKit: Mach-O universal binary with 2 architectures
/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS3.1.2.sdk/System/Library/Frameworks/MapKit.framework/MapKit (for architecture armv6): Mach-O dynamically linked shared library arm
/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS3.1.2.sdk/System/Library/Frameworks/MapKit.framework/MapKit (for architecture armv7): Mach-O dynamically linked shared library arm

Go to Targets -> Build Phases -> Add CoreLocation Framework.
