xcode4.3及以上横空出世一个东东:UseAutolayout。
这个东东是在iOS6或者OSX 10.8上实现控件自动定位。是为了节省代码量的。好是好，只是现在写的东东都要兼容iOS5和10.7以下的系统。如果用了这东东，就没法在iOS6和10.8以下的系统上运行写的东东了。怎么取消这个东东呢？很简单，看图说话:
1.选中xib文件
2.在File Inspector那找到Use Auto Layout取消选中
然后就完事儿了
但是，怎么能完全禁用呢？
在下面两个路径下
/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/Library/Xcode/Templates/File Templates/User Interface/
/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/Library/Xcode/Templates/File Templates/Cocoa Touch
/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/Library/Xcode/Templates/File Templates/Cocoa Touch
这么弄一下:
grep UseAutolayout * -R
是不是发现一堆的xib文件里，有要找的东东:
Application.xctemplate/iPad/___FILEBASENAME___.xib: <bool key="IBDocument.UseAutolayout">NO</bool>
Application.xctemplate/iPhone/___FILEBASENAME___.xib: <bool key="IBDocument.UseAutolayout">NO</bool>
Empty.xctemplate/iPad/___FILEBASENAME___.xib: <bool key="IBDocument.UseAutolayout">NO</bool>
Empty.xctemplate/iPhone/___FILEBASENAME___.xib: <bool key="IBDocument.UseAutolayout">NO</bool>
View.xctemplate/iPad/___FILEBASENAME___.xib: <bool key="IBDocument.UseAutolayout">NO</bool>
View.xctemplate/iPhone/___FILEBASENAME___.xib: <bool key="IBDocument.UseAutolayout">NO</bool>
Window.xctemplate/iPad/___FILEBASENAME___.xib: <bool key="IBDocument.UseAutolayout">NO</bool>
Window.xctemplate/iPhone/___FILEBASENAME___.xib: <bool key="IBDocument.UseAutolayout">NO</bool>
Application.xctemplate/iPhone/___FILEBASENAME___.xib: <bool key="IBDocument.UseAutolayout">NO</bool>
Empty.xctemplate/iPad/___FILEBASENAME___.xib: <bool key="IBDocument.UseAutolayout">NO</bool>
Empty.xctemplate/iPhone/___FILEBASENAME___.xib: <bool key="IBDocument.UseAutolayout">NO</bool>
View.xctemplate/iPad/___FILEBASENAME___.xib: <bool key="IBDocument.UseAutolayout">NO</bool>
View.xctemplate/iPhone/___FILEBASENAME___.xib: <bool key="IBDocument.UseAutolayout">NO</bool>
Window.xctemplate/iPad/___FILEBASENAME___.xib: <bool key="IBDocument.UseAutolayout">NO</bool>
Window.xctemplate/iPhone/___FILEBASENAME___.xib: <bool key="IBDocument.UseAutolayout">NO</bool>
就是改这些文件喽。直接一句话搞定：
sudo find . -name *.xib -exec sed -i '' -e '/UseAutolayout/{s/YES/NO/;}' {} \;
ok，这下真的清净了。。
改回来的话，也简单，YES和NO交换一下位置就可以了
sudo find . -name *.xib -exec sed -i '' -e '/UseAutolayout/{s/NO/YES/;}' {} \;
不用怀疑，以上命令实时生效，可以去xcode看效果了。
