DeveloperUG 2013: Developing for iOS - When to do what and how

In this session we will look at the tools, framework and languages available to build applications for the iOS. The session will explore various development approaches for creating iOS apps including native, hybrid and web. Tools that we be covered include Xcode (ObjC), MonoTouch (C#) and other web-based and hybrid frameworks.

This session will also discuss development strategies to apply when targeting many devices.

  6. Literals NSNumber *number;! ! number = [NSNumber numberWithChar:'X'];! number =

    [NSNumber numberWithInt:12345];! number = [NSNumber numberWithUnsignedLong:12345ul];! number = [NSNumber numberWithLongLong:12345ll];! number = [NSNumber numberWithFloat:123.45f];! number = [NSNumber numberWithDouble:123.45];! number = [NSNumber numberWithBool:YES];! number = @'X’;! number = @12345;! number = @12345ul;! number = @12345ll;! number = @123.45f;! number = @123.45;! number = @YES;!
  7. Literals dict = [NSDictionary dictionaryWithObjects:@[o1, o2, o3]! forKeys:@[k1, k2, k3]];!

    ! dict = @{ k1 : o1, k2 : o2, k3 : o3 };! ! ! ! ! array = [NSArray arrayWithObjects:a, b, c, nil];! ! array = @[ a, b, c ];! !

  14. Frank Feature: General (Main)! Scenario: My details! ! Given I

    logged in with "my-user-1" ! And I wait for "Logging in…" to go away! When I touch the "My Details" table cell! Then I wait to see a navigation bar titled "My Details"! And I should see a table containing the following:! | Column 1 |! | Username | ! | Email |! | First Name |! ...! When I type "Martin" into the Username text field! And I ...!
  15. Frank Then /^I wait to see a navigation bar titled

    "([^\"]*)"$/ do |expected_mark|! quote = get_selector_quote(expected_mark)! message = "waited to see a navigation bar titled #{quote}#{expected_mark}#{quote}"! wait_until( :timeout => 30, :message => message) {! element_exists( "navigationItemView marked:#{quote}#{expected_mark}#{quote}" )! }! end! !

  16. Frank Then /^I should see a table containing the following:$/

    do |table|! ! table.rows.each do |row|! selector = String.new! ! row.each do |cell|! if selector.empty?! selector = "tableView view marked:'#{cell}'"! else! selector << " parent tableViewCell view marked:'#{cell}'"! end! end! check_element_exists( selector )! end! end!
