cocoa pods报错The dependency `Reveal-iOS-SDK` is not used in any concrete target.

Podfile错误写法,会报错The dependency `Reveal-iOS-SDK` is not used in any concrete target.

platform:ios,'7.0'

pod 'Reveal-iOS-SDK', :configurations => ['Debug']

Podfile正确的写法：

platform:ios,'7.0'

target 'WeiYiTest' do
pod 'Reveal-iOS-SDK', :configurations => ['Debug']
end

修改Podfile之后，Pod install就没有问题了，Pod update也没问题。
