XCODE 6 (6A313) Compile Error using Outlets

问题:

I am using Xcode 6(6A313) to develop an example app (use objective-c), follow the book IOS Programming 4 edition Big Nerd Ranch that is made to work with Xcode 5 however this basic app that has only 2 labels an 2 bottoms get a compile error "ViewController.xib: error: Illegal Configuration: Launch screens may not have connections." when i connect the outlet property with the view controls using Interface Builder.

Anyone has idea whats wrong?

Thank's in advanced

The ability to use a nib or storyboard instead of a launch image is new in Xcode 6, but the view in your launch storyboard can't have outlets.

It seems that you have outlets in the file that is being used for your launch screen. Xcode 6 template projects will now create two files - main.storyboard and LaunchScreen.xib.

Either remove the outlets from LaunchScreen.xib or go to your target and remove the value from the "Launch Screen File" field -
