Connecting with the Enterprise

The how and why of Enterprise integrations with RubyMotion

Who the heck is this guy?Kevin Poorman, Architect at West Monroe Partners

@codefriar -- Hey, I just met you, And this is crazy, But here's my twitter, So follow me, maybe!

Boring corporate bio here.-- West Monroe Partners.

#MyBabyDaughterTessa!, #Homebrew(beer), #Ruby, #AngularJS, #Iot, #Salesforce, #!Java, #!Eclipse, #FriendsDontLetFriendsUseEclipse #!boringCorporateness

Agenda

1. Why Enterprise software?

2. Challenges - We'll need a Young priest and an Old priest

3. Tools - We can do it!

4. A Salesforce Example

Why Enterprise Software?

Flappy birds versus Email.

This is an interactive bit.

Why Enterprise Software?so chart. much up and to the right. wow.

Why Enterprise Software?

Enterprise Software Stinks.

Design is not simply art, it is the elegance of function.-- F. Porsche

ChallengesLies, Damn Lies, and SDK's

1. Rest Apis Rest "ish" Apis, Soap Apis and SDKs

2. Authentication - Oauth or else

3. Data Integrity and Security

ToolsTime for the how

1. Cocoapods

— ZKsForce

2. Gems

— AFMotion

3. Rakefile!

An example with Enterprise CRM Software vendor Salesforce.

Resetting passwords like a Boss.

Talk is cheap, Show me the Code.

— Linus Torvald

Enter the Rakefile: Frameworks

### Application Frameworks# You can *add* to this as neccessary but this is the minimum required# for Salesforce iOS SDK Use.app.frameworks += %w(CFNetwork CoreData MobileCoreServices SystemConfiguration Security)app.frameworks += %w(MessageUI QuartzCore OpenGLES CoreGraphics sqlite3)

— How do you know which ones you need?

(lucky) ? Docs : Build Errors

Enter the Rakefile: Libraries

### Additional libraries needed for Salesforce iOS SDK# You can generally add just about any dylib or static .a lib this way# These are system dylibsapp.libs << "/usr/lib/libxml2.2.dylib"app.libs << "/usr/lib/libsqlite3.0.dylib"app.libs << "/usr/lib/libz.dylib"# These are provided by Salesforces' iOS SDK.app.libs << "vendor/openssl/libcrypto.a"app.libs << "vendor/openssl/libssl.a"# app.libs << "vendor/RestKit/libRestKit.a"# app.libs << "vendor/SalesforceCommonUtils/libSalesforceCommonUtils.a"# app.libs << "vendor/SalesforceNativeSDK/libSalesforceNativeSDK.a"# app.libs << "vendor/SalesforceOAuth/libSalesforceOAuth.a"app.libs << "vendor/sqlcipher/libsqlcipher.a"# app.libs << "vendor/SalesforceSDKCore/libSalesforceSDKCore.a"app.libs << "vendor/sqlcipher/libsqlcipher.a"

Enter the Rakefile: Vendor'd Projects

# RestKitapp.vendor_project "vendor/RestKit", :static, :headers_dir => "RestKit"

# Salesforce Common Utilsapp.vendor_project "vendor/SalesforceCommonUtils",:static,:headers_dir => "Headers/SalesforceCommonUtils"

Enter the RakeFile: When good vendors go bad

# Salesforce Native SDKapp.vendor_project "vendor/SalesforceNativeSDK",:static,:headers_dir => "include/SalesforceNativeSDK"

Warning, a wall of boring, soulless, corporate code is coming.

class AppDelegate

attr_accessor :window, :initialLoginSuccessBlock, :initialLoginFailureBlock

# def OAuthLoginDomain() # # You can manually override and force your app to use # # a sandbox by changing this to test.salesforce.com # "login.salesforce.com" # end

def application(application, didFinishLaunchingWithOptions:launchOptions) if self SFLogger.setLogLevel(SFLogLevelDebug) SFAccountManager.setClientId(RemoteAccessConsumerKey()) SFAccountManager.setRedirectUri(OAuthRedirectURI()) SFAccountManager.setScopes(NSSet.setWithObjects("api", nil)) NSNotificationCenter.defaultCenter.addObserver(self, selector: :logoutInitiated, name: "kSFUserLogoutNotification", object:SFAuthenticationManager.sharedManager) NSNotificationCenter.defaultCenter.addObserver(self, selector: :loginHostChanged, name: "kSFLoginHostChangedNotification", object:SFAuthenticationManager.sharedManager)

@weakSelf = WeakRef.new(self) self.initialLoginSuccessBlock = lambda { |info| @weakSelf.setupRootViewController }

self.initialLoginFailureBlock = lambda { |info,error| SFAuthenticationManager.sharedManager.logout }

end self.window = UIWindow.alloc.initWithFrame(UIScreen.mainScreen.bounds) self.initializeAppViewState SFAuthenticationManager.sharedManager.loginWithCompletion(self.initialLoginSuccessBlock, failure:self.initialLoginFailureBlock) true end

def initializeAppViewState() @window.rootViewController = InitialViewController.alloc.initWithNibName(nil, bundle:nil) @window.makeKeyAndVisible end

def setupRootViewController() navVC = UINavigationController.alloc.initWithRootViewController(HomeScreen.new) @window.rootViewController = navVC end

def logoutInitiated(notification) self.log.SFLogLevelDebug(msg:"Logout Notification Recieved. Resetting App") self.initializeAppViewState SFAuthenticationManager.sharedManager.loginWithCompletion(self.initialLoginSuccessBlock, failure:self.initialLoginFailureBlock) end

def loginHostChanged(notification) self.log.SFLogLevelDebug(msg:"Login Host Changed Notification Recieved. Resetting App") self.initializeAppViewState SFAuthenticationManager.sharedManager.loginWithCompletion(self.initialLoginSuccessBlock, failure:self.initialLoginFailureBlock) end

end

And now for the actually useful bit in all that

def setupRootViewController() # Yeah, if you could just replace the root view controller with a ProMotion # Screen, that'd be great. navVC = UINavigationController.alloc.initWithRootViewController(HomeScreen.new) @window.rootViewController = navVC end

Using the SDK Functions

def query_sf_for_users results = SFRestAPI.sharedInstance.performSOQLQuery( # Salesforce has a fun variant on Sql called # "SOQL" or Salesforce Object Query Language. # First Argument is the Query we want to run. "SELECT id, Name, LastName FROM user", failBlock: lambda {|e| ap e }, # Method is a fun Method that invokes the named # method as a lambda. completeBlock: method(:sort_results) ) end

Using the SDK functions

def reset_password args UIAlertView.alert("Reset Users Password?", buttons: ["Cancel", "OK"], message: "Salesforce will reset their password!") { |button| if button == "OK" results = SFRestAPI.sharedInstance.requestPasswordResetForUser( @id, # id of user to invoke password reset. failBlock: lambda {|e| ap e }, completeBlock: method(:password_reset_complete) ) end }end

def password_reset_complete response if(Twitter.accounts.size > 0) UIAlertView.alert("Password Reset!", buttons: ["OK", "Tweet"]) { |button| tweet if button == "Tweet" } endend

ObjC2RubyMotion

Turns this:

RootViewController *rootVC = [[RootViewController alloc] initWithNibName:nil bundle:nil]; UINavigationController *navVC = [[UINavigationController alloc] initWithRootViewController:rootVC]; self.window.rootViewController = navVC;

Into this:

rootVC = RootViewController.alloc.initWithNibName(nil, bundle:nil) navVC = UINavigationController.alloc.initWithRootViewController(rootVC) self.window.rootViewController = navVC
