cs193p – Project #4 Assignment #4 Task #3

Please note, this blog entry is from a previous course. You might want to check out the current one.

Each section in the mentions table view should have an appropriate header.

We store already the title in our data structure, now just use it:

    override func tableView(tableView: UITableView, titleForHeaderInSection section: Int) -> String? {
        return mentions[section].title
    }

The complete code for task #3 is available on GitHub.

cs193p – Project #4 Assignment #4 Task #2

Please note, this blog entry is from a previous course. You might want to check out the current one.

When a user clicks on a Tweet, segue to a new UITableViewController which has four sections showing the “mentions” in the Tweet: Images, URLs, Hashtags and Users. The first section displays (one per row) any images attached to the Tweet (found in the media variable in the Tweet class). The last three show the items described in Required Task 1 (again, one per row).

Add a new table view controller to story board and a new table-view-controller class which you link to the new controller. Add a segue from the tweet cell too the new controller (don’t forget to add a segue identifier).

cs193p – Project #4 Assignment #4 Task #1

Please note, this blog entry is from a previous course. You might want to check out the current one.

Enhance Smashtag from lecture to highlight (in a different color for each) hashtags, urls and user screen names mentioned in the text of a Tweet (these are known as “mentions”). Note that mentions are already located for you in each Tweet by Twitter and show up as [IndexedKeyword]s in the Tweet class in the supplied Twitter code.

The tweet class provides nearly everything needed – arrays of indexed keywords. What’s left is to choose a color for the keyword type – as public properties of the cell view:

    var hashtagColor = UIColor.blueColor()
    var urlColor = UIColor.redColor()
    var userMentionsColor = UIColor.greenColor()

cs193p – Lecture #12 Dynamic Animation

Please note, this blog entry is from a previous course. You might want to check out the current one.

The twelfth lecture addresses a different approach to animation, creating sets of behaviors defining how items should interact with each other and the environment.

First we create an animator inside a reference view:

var animator = UIDynamicAnimator(referenceView: UIView)

cs193p – Lecture #11 Unwind Segues, Alerts, Timers, View Animation

Please note, this blog entry is from a previous course. You might want to check out the current one.

The eleventh lecture is theory only, starting with detailed discussion about the final project (which might only be interesting for Stanford students).

Unwind Segue

Unwind Segues provide a way to segue back to MVCs which directly or indirectly presented the current segue.

cs193p – Lecture #10 Table View

Please note, this blog entry is from a previous course. You might want to check out the current one.

Though the lecture is called table view it starts with a “bonus topic”:

UITextField

The keyboard appears when a text field becomes first responder (becomeFirstResponder) and desperadoes when it resigns to be first responder (resignFirstResponder). To know when the return key has been pressed (functextFieldShouldReturn) or when editing has ended (textFieldDidEndEditing) is controlled via delegates or target/action notifications.

cs193p – Project #3 Assignment #3 Extra Task #6

Please note, this blog entry is from a previous course. You might want to check out the current one.

Have your Calculator react to size class changes by laying out the user-interface differently in different size class environments (i.e. buttons in a different grid layout or even add more operations in one arrangement or the other). Doing this must not break anything else!

Most likely for the first step it is best to remove all constraints. Add some new buttons (I added a tangens operation, the euler constant and two blank buttons). Arrange them into an additional column. Have fun adding back the constraints (which does not really differ from the previous assignments …)
