Xcode 常见问题记录

1: Multiple commands produce '/Users/shuxia/Library/Developer/Xcode/DerivedData/BaseProjectForApp-birqtphktluqlfbqehlcahzcmqza/Build/Products/Debug-iphoneos/BaseProjectForApp.app/Info.plist':

1) Target 'BaseProjectForApp' (project 'BaseProjectForApp') has copy command from '/Users/shuxia/私人代码/个人研究/BaseProjectForApp/BaseProjectForApp/Other/Info.plist' to '/Users/shuxia/Library/Developer/Xcode/DerivedData/BaseProjectForApp-birqtphktluqlfbqehlcahzcmqza/Build/Products/Debug-iphoneos/BaseProjectForApp.app/Info.plist'

2) Target 'BaseProjectForApp' (project 'BaseProjectForApp') has process command with output '/Users/shuxia/Library/Developer/Xcode/DerivedData/BaseProjectForApp-birqtphktluqlfbqehlcahzcmqza/Build/Products/Debug-iphoneos/BaseProjectForApp.app/Info.plist'

解决办法:找到对应文件(上面说的是Info.plist) 然后去到 buildPhase 里面的Copy bundle Resource  里面 删除掉 infoPlist文件

2. Build input file cannot find @"XXXXXX"

这种直接 去link  Library  里面 在引入一次就可以了
