VLCKit编译脚本的防坑修改
前言：编译过VLC的朋友们可能都知道，整个流程编译下来，在没任何错误的情况下基本上需要3到4个小时，网速慢点的可能需要7-8个小时，如果中途出现错误，很可能需要重新来过，那么有什么方法可以防坑呢？
作者在尝试编译多次VLC之后总结和修改了编译脚本。
据我观察，编译VLC的时候，大部分时间都会消耗在buildMobileVLCKit.sh 文件中153行附近的
git clone git://git.videolan.org/vlc.git vlc这行代码上。
所以防坑的原则就是修改脚本只执行这一句代码，执行完毕之后将整个目录压缩成zip保存，然后以后编译的时候，出现错误就可以随时重来，方便快捷
1、怎么修改代码
VLCKit3.0.0-pre2的源代码是：

}
执行完脚本之后，我们实际上就操作了一个功能，就是
git clone git://git.videolan.org/vlc.git vlc
然后我们将整个目录打包
2、再次编译我们应该怎么用脚本？
buildMobileVLCKit.sh 已经被我们删的不可恢复了，我们使用原版的buildMobileVLCKit.sh继续修改153行附近的代码
原代码是：
info "Preparing build dirs"
mkdir -p MobileVLCKit/ImportedSources
spushd MobileVLCKit/ImportedSources
if [ "$NONETWORK" != "yes" ]; then
if ! [ -e vlc ]; then
git clone git://git.videolan.org/vlc.git vlc
info "Applying patches to vlc.git"
cd vlc
git checkout -B localBranch ${TESTEDHASH}
git branch --set-upstream-to=origin/master localBranch
git am ../../patches/*.patch
if [ $? -ne 0 ]; then
git am --abort
info "Applying the patches failed, aborting git-am"
exit 1
fi
cd ..
else
cd vlc
git pull --rebase
git reset --hard ${TESTEDHASH}
git am ../../patches/*.patch
cd ..
fi
fi
spopd
我们去掉
if ! [ -e vlc ]; then
中的感叹号
if [ -e vlc ]; then然后我们 注释掉
git clone git://git.videolan.org/vlc.git vlc
最后代码是
info "Preparing build dirs"
mkdir -p MobileVLCKit/ImportedSources
spushd MobileVLCKit/ImportedSources
if [ "$NONETWORK" != "yes" ]; then
if [ -e vlc ]; then

以后我们就用这个脚本执行我们的zip保存下来的代码，有问题随时可以重来
有了这个方法每次编译VLCKit的时候能省下两个小时时间
