2. Springest
is a
Website
where you can
find and
compare courses.

3. My
Springest
Track found
courses,
enrolments
finished courses

4. Discovery
automated
suggestions based
on e.g. your
search history
and LinkedIn
profile.

5. Why an iOS App?
More personalised feel
!
Once installed, you
carry it everywhere
!
Push notifications

6. My First
App
(Being A Web
Developer And
All..)

7. Location
Services
to select the
right localised
site for you.

8. AND even
persistent cookies,
LinkedIn
integration...

9. Big Apple
says no.

10. WebView?
REJECTED. Period.

11. Dammit.

13. // Password field
_passwordField = [[UITextField alloc] initWithFrame:
CGRectMake(72, 394, 180, 30)];
[_passwordField setBorderStyle:UITextBorderStyleRoundedRect];
_passwordField.placeholder = @"Password";
_passwordField.secureTextEntry = YES;
_passwordField.delegate = self;
[_passwordField setReturnKeyType:UIReturnKeyDone];
[_passwordField addTarget:self
action:@selector(textFieldFinished:)
forControlEvents:
UIControlEventEditingDidEndOnExit];
_passwordField.tag = kPasswordField;
[_scrollView addSubview:_passwordField];

14. RubyMotion
whoah, ruby?

15. def application(
didFinishLaunchingWithOptions: launch_options )
Ruby? rly?

16. - (BOOL)application:(UIApplication *)application
didFinishLaunchingWithOptions:(NSDictionary
*)launchOptions
!
def application( application,
didFinishLaunchingWithOptions: launch_options )
!
- (BOOL)application:(UIApplication *)application
!
def application( application )
Compare these..

17. !
def application( application,
didFinishLaunchingWithOptions: launch_options )
!
!
!
def application( application )
That defines the same method twice!

18. // Sign in button
_signInButton = [UIButton buttonWithType:UIButtonTypeRoundedRect];
_signInButton.frame = CGRectMake(73, 432, 178, 30);
[_signInButton setTitle:@"Sign in" forState:UIControlStateNormal];
[_scrollView addSubview:_signInButton];
!
# Sign in button
@sign_in_button = UIButton.buttonWithType UIButtonTypeRoundedRect
@sign_in_button.frame = CGRectMake(73, 432, 178, 30)
@sign_in_button.setTitle: "Sign in", forState: UIControlStateNormal
@scrollView.addSubview: @sign_in_button
!
Much difference?

22. ProMotion
more ruby love

24. class AppDelegate < PM::Delegate
!
def on_load(app, options)
open RootScreen.new(nav_bar: true)
end
!
end
Now we’re talking Ruby

25. # app/screens/root_screen.rb
!
class RootScreen < PM::Screen
title "Root Screen"
!
def on_load
set_nav_bar_button :right, title: "Help", action: :help
end
!
def help
open HelpScreen
end
end
PM::Screen

26. def on_load
set_attributes self.view, {
background_color: hex_color("DBDBDB")
}
add UILabel.new, {
text: "August",
text_color: hex_color("8F8F8D"),
background_color: UIColor.clearColor,
shadow_color: UIColor.blackColor,
text_alignment: UITextAlignmentCenter,
font: UIFont.systemFontOfSize(15.0),
resize: [ :left, :right, :bottom ],
frame: CGRectMake(10, 0, 300, 35)
}
end
PM::Styling

27. Thanks!
spread the ruby love
