Boring corporate bio here.

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.

so chart. much up and to the right. wow.

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

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

Tools
Time 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 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"

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"

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.

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

# Specify your connected app's consumer key here

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.

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")
end
def loginHostChanged(notification)
self.log.SFLogLevelDebug(msg:"Login Host Changed Notification Recieved. Resetting App")
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"
}
end
end

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

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*.
