Hello, the problem has been resolved, this is my xib file is loaded into the manual add file, this time, there is no record of the project record file, there will be problems on the real machine, I would xib file and the corresponding class file is deleted By adding the new wizard files, xml code xib files to copy to replace it, no problem. This seems to be the reason xcode itself, but how to change the project record documents had not been thoroughly studied, to be studied, first thanked, points gave you.
