The document "X.xib" could not be opened. Could not read archive. Please use a newer version of Xco

问题：

xib文件在Xcode 5建立，现在需要在Xcode 4.6打开运行。

报错：

The document "DetailTransactionPage.xib" could not be opened. Could not read archive.

Please use a newer version of Xcode. Consider changing the document's Development Target to preserve compatibility

解决：

用Xcode5打开项目，修该下Opens in的参数。

具体：

1，Right click on XXX.xib file and select "Show File Inspector."

2，Go to Interface Builder Document.

3，Change Development option with the version of Xcode you are using.

注意：

修改时Xcode也会提醒，如果改成支持4.6的，那么5.0的一些界面特征也会相应被修改。
