Auto increment build number by run script. (Xcode)

Posted on

1. to add key in your Project-info.plist
CFBuildNumber, CFBuildDate
2. add scripts to your run script (in Xcode)
CFBuildNumber=$(/usr/libexec/PlistBuddy -c “Print CFBuildNumber" $myPlist)
CFBuildNumber=$(($CFBuildNumber + 1))
/usr/libexec/PlistBuddy -c “Set :CFBuildNumber $CFBuildNumber" $myPlist
/usr/libexec/PlistBuddy -c “Set :CFBuildDate $CFBuildDate" $myPlist
echo “build number: " $CFBuildNumber

3. get info from Project-info.plist and show on somewhere.
NSString * version = [[[NSBundle mainBundle] infoDictionary] objectForKey:@"CFBundleVersion"];
NSString * buildNo = [[[NSBundle mainBundle] infoDictionary] objectForKey:@"CFBuildNumber"];
NSString * buildDate = [[[NSBundle mainBundle] infoDictionary] objectForKey:@"CFBuildDate"];
