刚才去官网下载文档,发现一些新的已经用上新UI了,比如这个讲UIKit User Interface Catalog: https://developer.apple.com/library/ios/documentation/UserExperience/Conceptual/UIKitUICatalog/index.html#//apple_ref/doc/uid/TP40012857
还有一些还是原来的老UI,比如讲Simulator的: https://developer.apple.com/library/ios/documentation/IDEs/Conceptual/iOSSimulatorGuide/Introduction/Introduction.html#//apple_ref/doc/uid/TP40012848
如果都能用新的就好了,老的看着好别扭啊~
