iOS app中获取git信息

具体的Demo：https://github.com/y500/GetGitInfo

测试定位bug需要，在APP内部展示git的相关信息，具体思路就是通过script脚本获取到想到的信息然后存入info.plist中，然后需要的时候再从info.plist中取出。

1. 在xcode的build phase中加入script：

#最后一次提交的SHA

git_version=$(git log -1 --format="%h")

#当前的分支

git_branch=$(git symbolic-ref --short -q HEAD)

#最后一次提交的作者

git_last_commit_user=$(git log -1 --pretty=format:'%an')

#最后一次提交的时间

git_last_commit_date=$(git log -1 --format='%cd')

#编译时间build_time=$(date)

info_plist="${BUILT_PRODUCTS_DIR}/${EXECUTABLE_FOLDER_PATH}/Info.plist"

/usr/libexec/PlistBuddy -c "Set :'GitCommitSHA' '${git_version}'" "${info_plist}"

/usr/libexec/PlistBuddy -c "Set :'GitCommitBranch' '${git_branch}'" "${info_plist}"

/usr/libexec/PlistBuddy -c "Set :'GitCommitUser' '${git_last_commit_user}'" "${info_plist}"

/usr/libexec/PlistBuddy -c "Set :'GitCommitDate' '${git_last_commit_date}'" "${info_plist}"

/usr/libexec/PlistBuddy -c "Set :'BuildTime' '${build_time}'" "${info_plist}"

 2. 在info.plist中加入对象的键值对：

<key>GitCommitSHA</key>

<string></string>

<key>GitCommitBranch</key>

<string></string>

<key>GitCommitUser</key>

<string></string>

<key>GitCommitDate</key>

<string></string>

<key>BuildTime</key>

<string></string>

 3. 带代码获取并使用：

NSDictionary *infoDic = [[NSBundle mainBundle] infoDictionary];

_commitLabel.text = [NSString stringWithFormat:@"最后提交SHA：%@", [infoDic objectForKey:@"GitCommitSHA"]];

_branchLabel.text = [NSString stringWithFormat:@"当前所在分支：%@", [infoDic objectForKey:@"GitCommitBranch"]];

_authorLabel.text = [NSString stringWithFormat:@"最后提交用户：%@", [infoDic objectForKey:@"GitCommitUser"]];

_dateLabel.text = [NSString stringWithFormat:@"最后提交时间：%@", [infoDic objectForKey:@"GitCommitDate"]];

_buildTimeLabel.text = [NSString stringWithFormat:@"本次编译时间：%@", [infoDic objectForKey:@"BuildTime"]];

效果如下图
