title: iphone / ipad - Compile three20 under xcode 4?
body: <p>anyone successfully compiled three20 under XCode 4?</p>
  
  <p>I tried, and changed all Base SDK to latest 4.2, but there is alway a error:</p>
  
  <p>error: There is no SDK with the name or path '..../three20/src/Three20Core/iphoneos4.0'</p>
  
  <p>in Three20UICommon and its Unit tests.</p>
  
  <p>Anyone has a clue about this?</p>
  
  <p>Also, in Xcode 3, I know I can let all UnitTests not to be compiled by deselecting the bulleye for UnitTests. How can I do it in XCode 4?</p>
  
  <p>thanks</p>
