错误ignoring file xxx missing required architecture x86_64 in file
解决方法：
1、在Project target里“Architectures”设置为：Standard （armv7,armv7s）或者 Standard (armv7,arm64)
2、设置”Build Active Architecture Only”为“NO”
3、在Project target里“Build Settings”的“Valid Architectures”添加“i386” ，去掉arm64,留下armv7,armv7s还有新添加的i386就可以了
