My understanding of how to define a view or view controller

1, view

View is an element of a full screen page.

"View controllers are a vital link between an app’s data and its visual appearance"

What view does is to reuse the same ui design and the same user interactions.

lin

<!--  http://www.html5rocks.com/en/tutorials/file/dndfiles/#toc-reading-files -->

<script>
  function handleFileSelect(evt) {
    var files = evt.target.files; // FileList object

    // Loop through the FileList and render image files as thumbnails.
    for (var i = 0, f; f = files[i]; i++) {

      // Only process image files.

1, git remote -v, check remote links

origin	https://github.com/rmajmudar/popinshop.git (fetch)
origin	https://github.com/rmajmudar/popinshop.git (push)

2, git remote rm origin, remove old remote links

3, git remote -v, check remote links, it should be empty now.

4, git remote add origin https://github.com/linyingkui/popinshop.git, add new remote links

Follow heroku tutorials:

1, new rails app

rails new albertly --database=postgresql

2, setup the database

lin

1, A layer is just a container for managing a bitmap image

2，The job of a view controller is to manage a view hierarchy

3, The viewWillLayoutSubviews method is also called after the view is resized and positioned by its parent. When a view's bounds change, the view adjusts the position of its subviews.

4, A view controller: resizes and lays out its views, adjusts the contents of the views, acts on behalf of the views when the user interacts with them

lin

1, read changes

git diff difference between current codes and HEAD codes

git diff HEAD the same as git diff

git diff HEAD^^ two commits before HEAD

git diff HEAD~5 five commits before HEAD

lin

// temp

func application(application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: NSData) {
    let mixpanel = Mixpanel.sharedInstance()
    if let user = LUVApi.sharedInstance().currentUser {
        mixpanel.identify(user.id)
        mixpanel.people.addPushDeviceToken(deviceToken)
    }
}
