1.模拟器上运行正常，但是真机调试时报编译链接错误
：ld: '/Users/wangqipeng/Desktop/iOS支付宝官方文档/AlixPayDemo/libcrypto.a(bio_lib.o)' does not contain bitcode. You must rebuild it with bitcode enabled (Xcode setting ENABLE_BITCODE), obtain an updated library from the vendor, or disable bitcode for this target. for architecture armv7
clang: error: linker command failed with exit code 1 (use -v to see invocation)
解决方法：在Build Setting中查找bitcode，将Enable Bitcode改为NO就可以了
2.平时调试程序时，有时会报No matching provisioning profiles found 的警告，真机调试会报错
解决方法：修改Bundle Identifier ，给当前的bundle id随便添加几个字符就行，但是真机调试过之后要改为原来的Bundle id，否则不可以连续运行的
3.ld: file not found: /Users/wangqipeng/Library/Developer/Xcode/DerivedData/UITest-fwixyyhkflydsbeztbylckujcsyo/Build/Products/Debug-iphonesimulator/UITest.app/UITest clang: error: linker command failed with exit code 1 (use -v to see invocation)
将项目考到新电脑中出现错误
改Build Setting中改一下项目名字就好了
原因，项目名不同造成的
