language: objective-c

osx_image: xcode7.2

script: 
   xctool -project ProjectName.xcodeproj -scheme ProjectName build -sdk iphonesimulator

当Travis正在运行时,我遇到了这个错误：

$xctool -project ProjectName.xcodeproj -scheme ProjectName build -sdk iphonesimulator

ERROR: Cannot find schemes. Please consider creating shared schemes in Xcode.

TIP: This might happen if you’re relying on Xcode to autocreate your schemes
and your scheme files don’t yet exist. xctool,like xcodebuild,isn’t able to
automatically create schemes. We recommend disabling “Autocreate schemes”
in your workspace/project,making sure your existing schemes are marked as
“Shared”,and making sure they’re checked into source control.
