Question

I’m trying to update an app that already have the Three20 library. Now i’m using xcode 4.5 and everytime i try to make an Archive i recive this error:

Three20/Three20.h file not found

At the beginning i wasn’t able to make any kind of build,but after the adding of $(BUILT_PRODUCTS_DIR)/../three20 and $(BUILT_PRODUCTS_DIR)/../../three20 in the Header Search Path of the build and the target settings i can make a Build in my Device. Anyway if i try to made an Archive to publish my app, the same errors returns. What i can do? I have already reinstall the last version of Three20…. I have to try this solution that i found on internet:

Go to Xcode4 Preferences (Cmd + ,) > Locations > Build Location > and select “Place build products in locations specified by targets”

In xcode 4.5 i can’t approach this solution…Maybe Build Location menù is changed, i can’t find the option “Place build products in locations specified by targets” …. Someone knows where i can found this setting?

At least there’s someone how have made successfully an Archive on Xcode4.5 and Three20?

Three20 has’t update in long time.And it has many bugs.set up this framework is very hard.

you can try nimbus.It come from three20.

Nimbus’ Background

Nimbus has been built with much inspiration from the Three20
framework. That being said, there are a number of fundamental problems
with Three20 that Nimbus works very hard to avoid. Among them:

Poor documentation. Spaghetti dependencies. Suffering from a “kitchen
sink” complex. A complex build structure. An enormous number of
difficult-to-solve bugs. Next-to-zero test coverage. For its
weaknesses, Three20 does provide a good deal of value through its
feature set. It is used in over 100 apps in the app store by companies
such as Facebook, LinkedIn, Posterous, Meetup, and SCVNGR.

Nimbus hopes to one day provide as much value as Three20 does on a
feature-by-feature comparison, but with the invaluable benefit of
sublime documentation and test coverage.
