运行程序报错
ld: file not found: ~/Library/Developer/Xcode/DerivedData/xxx-fxhqtzymbwegttddoznsqpakmlvp/Build/Products/Debug-iphonesimulator/xxx.app/xxx
clang: error: linker command failed with exit code 1 (use -v to see invocation)
clean 项目后 删除DerivedData后 重启Xcode不起作用
2种解决办法
1）左击工程文件：
选择Edit Scheme
把红色圈住的去掉就ok了
2）Proj->BuildingSetting-搜应用名 ->Product Name更改为和 Executable file一致（proj->info->Executable file）
DerivedData/xxx-fxhqtzymbwegttddoznsqpakmlvp/Build/Products/Debug-iphonesimulator/xxx.app/xxx
