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

NSNotification

Notifications provide a way to react to asynchronous events. e.g.:

NSNotificationCenter.defaultCenter()

func addObserverForName(String, // name of the "radio station"
    object: AnyObject?, // broadcaster (or nil for "anyone")
    queue: NSOperationQueue?) // queue to execute the closure on 
    { (notification: NSNotification) -> Void in
        let info: [NSObject:AnyObject]? = notification.userInfo // notification-specific information
}

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.

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 – Lecture #9 Scroll View and Multithreading

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

The lecture starts with additional information on how to control the appearance of a view in different size classes and how to inspect constraints in various size classes.

Scroll Views

Adding sub views to a scroll view works similar like adding views to any other view. The only important difference is to define the content size of the scroll view:

scrollView.contentSize = CGSize(width: 3000, height: 2000)
logo.frame = CGRect(x: 2700, y: 50, width: 120, height: 180)
scrollView.addSubview(logo)
aerial.frame = CGRect(x: 150, y: 200, width: 2500, height: 1600)
scrollView.addSubview(aerial)
