注意事项：1、模拟器和真机运行过后才可以看到下图所示的路径：
2、lipo -create "真机版本路径" "模拟器版本路径" -output "合并后的文件路径"
// 模拟器路径
/Users/a1/Library/Developer/Xcode/DerivedData/IJKMediaPlayer-fnmqgmrwrolbtxdhrghdebgtuibm/Build/Products/Release-iphonesimulator/IJKMediaFramework.framework/IJKMediaFramework
//真机路径
/Users/a1/Library/Developer/Xcode/DerivedData/IJKMediaPlayer-fnmqgmrwrolbtxdhrghdebgtuibm/Build/Products/Release-iphoneos/IJKMediaFramework.framework/IJKMediaFramework
// 合成路径 需要在Products后添加/IJKMediaFramework
/Users/a1/Library/Developer/Xcode/DerivedData/IJKMediaPlayer-fnmqgmrwrolbtxdhrghdebgtuibm/Build/Products/IJKMediaFramework
