Travis
  Hosted Continuous Integration service
  Configuration file in your project (.travis.yml)
  Define SDK, build env and output
  custom scripts
  Connected to Github
  Triggers in every push and pull request
  Available for many platforms

Travis Setup (.travis.yml)
  It’s not using the iPhone SDK
  code signing is needed
  Doesn’t differentiate between branches
  Doesn’t archive
  Doesn’t distribute
language: objective-c
xcode_project: MyNewProject.xcodeproj
xcode_scheme: MyNewProjectSharedScheme
iPhone SDK
custom build per branch
generate .ipa
distribute

Import keys (import-keys.sh)
# 1. Create keychain
security create-keychain -p travis ios-build.keychain
# 2. Make as default
security default-keychain -s ios-build.keychain
# 3. Unlock keychain
security unlock-keychain -p travis ios-build.keychain
# 4. Add certificates to keychain
security import ./ios-travis-ci/certificates/dist.cer -k ios-build.keychain -T /usr/bin/codesign
security import ./ios-travis-ci/certificates/dist.p12 -k ios-build.keychain -P $KEY_DIST_PASSWORD
-T /usr/bin/codesign
# 5. Copying provisioning profile to Travis
mkdir -p ~/Library/MobileDevice/Provisioning Profiles
cp ./ios-travis-ci/profiles/*.mobileprovision ~/Library/MobileDevice/Provisioning Profiles/

Security
  You can encrypt environment variables using
Travis command line tool on your terminal:
~ $ travis ecrypt ‘KEY_DIST_PASSWORD=abc123’ –add
  Passing the option “--add” will automatically add the secure
key to your .travis.yml
env:
global:
- secure: Pz3cxDffsdafasf34324fdsf232fdsfdsf3fdsf

  Use iPhone SDK ✅
  Doesn’t differentiate between branches
env:
global:
before_script:
- ./scripts/import-key.sh
script:
- xctool -workspace MyNewProject.xcworkspace -scheme MySharedScheme -sdk iphoneos -configuration Beta
iPhone SDK
generate .ipa

Building (build_app.sh)
# 1.
xctool -workspace ${APP_NAME}.xcworkspace
-scheme ${APP_NAME}
-sdk iphonesimulator test
…
# 2.
export RELEASE_SUFFIX=".release”
# Bundle Identifier:
# com.getyourguide.mobile.$(PRODUCT_NAME:rfc1034identifier)${BUNDLE_ID_SUFFIX}$
{RELEASE_SUFFIX}

  Differentiate between branches ✅
env:
global:
before_script:
script:
- ./scripts/build-app.sh
iPhone SDK
generate .ipa
distribute

# 1.
xcrun -sdk iphoneos PackageApplication
-v ”$BUILD_DIR/$APP_NAME.app"
-o ”$BUILD_DIR/$APP_NAME.ipa"
--sign "$DEVELOPER_NAME"
--embed ”$PROVISIONING_PROFILE"
…
# 2.
release_notes=`git log --since=1.week --pretty=format:"%an - %s"`
curl

-F notify="0"
-F release_type="2"
-F notes="$release_notes"
-F notes_type="0"
-F "ipa=@$outputdir/$APP_NAME.ipa"
-F "mobileprovision=@$provisioning_profile"
-H "X-HockeyAppToken: ${HOCKEY_APP_TOKEN}"
https://rink.hockeyapp.net/api/2/apps/upload # Uploading to HockeyApp
Archiving and uploading
(archive_and_upload.sh)
iPhone SDK
generate .ipa
distribute

  Differentiate between branches ✅
  Archive ✅
  Doesn’t distribute ✅
env:
global:
before_script:
script:
- ./scripts/build-app.sh
after_success:
- ./scripts/archive_and_upload.sh
iPhone SDK
generate .ipa
distribute

Move the scripts away from the app
repository (Optional)
  Maintenance 👍
  Reusable 👍
  Slower builds 👎
…
git:
submodules: false
before_install:
- git submodule init ios-travis-ci
- git submodule update --remote --merge ios-travis-ci

(Bonus) Overlaying Icons
  Add icon overlay script on the Build Phase of your target
IconOverlaying (by: Krzysztof Zabłocki)
…
before_install:
…
- brew install imagemagick && brew install ghostscript

Conclusion
  Automate tasks
  App is distributed
  No manual configuration
  Different actions between branches
  5 different apps to test concurrently
