Connecting with the Enterprise

Not everyone plays games; fewer games really take off. But we all use email, we all have systems that we login to just for work. These Enterprise systems are part of a large and ever-growing category of spending for IT Managers. But Enterprise systems ... stink. RubyMotion developers are in a unique position to integrate with these Enterprise Software systems while providing beautiful, functional and elegant interfaces. Join in as we learn why we should be writing Enterprise connected apps, and walk through an example of connecting to Salesforce using their iOS SDK.

1. Connecting with the Enterprise The how and why of Enterprise integrations with RubyMotion
2. 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
3. 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
4. Why Enterprise Software? Flappy birds versus Email. This is an interactive bit.
5. Why Enterprise Software? so chart. much up and to the right. wow.
6. Why Enterprise Software? Enterprise Software Stinks. Design is not simply art, it is the elegance of function. -- F. Porsche
7. Challenges Lies, 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
8. Tools Time for the how 1. Cocoapods — ZKsForce 2. Gems — AFMotion 3. Rakefile!
9. An example with Enterprise CRM Software vendor Salesforce. Resetting passwords like a Boss. Talk is cheap, Show me the Code. — Linus Torvald
10. 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
11. 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 dylibs app.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"
12. Enter the Rakefile: Vendor'd Projects # RestKit app.vendor_project "vendor/RestKit", :static, :headers_dir => "RestKit" # Salesforce Common Utils app.vendor_project "vendor/SalesforceCommonUtils", :static, :headers_dir => "Headers/SalesforceCommonUtils"
13. Enter the RakeFile: When good vendors go bad # Salesforce Native SDK app.vendor_project "vendor/SalesforceNativeSDK", :static, :headers_dir => "include/SalesforceNativeSDK" Warning, a wall of boring, soulless, corporate code is coming.
14. 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 RemoteAccessConsumerKey() # Specify your connected app's consumer key here "3MVG9A2kN3Bn17hsUZHiKXv6UUn36wtG7rPTlcsyH8K4jIUB2O2CU4dHNILQ_6lD_l9uDom7TjTSNEfRUE6PU" end def OAuthRedirectURI() # This must match the redirect url specified in your # connected app settings. This is a fake url scheme # but for a mobile app, so long as it matches you're good. "testsfdc:///mobilesdk/detect/oauth/done" end def dealloc() NSNotificationCenter.defaultCenter.removeObserver(self, name:"kSFUserLogoutNotification", object:SFAuthenticationManager.sharedManager) NSNotificationCenter.defaultCenter.removeObserver(self, name:"kSFLoginHostChangedNotification", object:SFAuthenticationManager.sharedManager) 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
15. 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
16. 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
17. 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" } end end
18. 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
19. Q & A Where we A some Q's Comments? Snide Remarks?
20. Thank You! Everything should be as simple as possible, but no simpler. -- A. Einstein Ps: Investigative reporters have discovered that RM 3.5, will include a third new Ruby Compiler -- for Windows and Windows Phone 8.1, this will, of course, be the only redeeming feature of Windows*.
