Creating a Swift Playground in XCode and adding it to a Git Repo on BitBucket

clockworkcode

In a previous post Creating a Swift Project in Xcode 6 and adding it to a git repo on BitBucket, I created a sample OXS command line project. I now want to create a collection of sample playgrounds to test out all of the language features of swift. Setting this up is essentially following the same set of steps but instead of section “Create a sample swift project (OSX command line tool)” do this instead:

Create a playground

  • Open XCode
  • File > New > File…
  • Choose template iOS > Source > Playground
  • Click Next
  • Save As: Sample.playground
  • Choose a suitable location e.g. ~/dev/repos/swift/samples
  • Click Create
  • A playground file will now open
  • Close the playground and follow the next section

Create a Git repo for the playground folder

Open a terminal window at e.g. ~/dev/repos/swift/samples

Now follow the instructions in the previous post from section “Create a Git Repo on BitBucket”

Using UIPageControl as a container UIViewController

My Memory

Setting up the interface

Setting up the PageViewController class

The PageViewController will contain 2 subview a UIScrollView and a UIPageControl. The UIScrollView will contain the views while the UIPageControl will navigate and control which part of the UIScrollView is visible.
You’ll also need some mechanism for calling addChildViewController: on the view controller, I’m my example I did this by sub-classing PagerViewController, but you could also do this before the view controller is push into view.

So, the public interface should look like this:

@interface PagerViewController : UIViewController 
 
@property (nonatomic, strong) IBOutlet UIScrollView *scrollView;
@property (nonatomic, strong) IBOutlet UIPageControl *pageControl;
 
- (IBAction)changePage:(id)sender;
 
@end

On to the implementation file. First of all, I want to handle all the view appearence at…

Some times we need to display picklist in Vf page which is of type picklist in Sobject. Acutally we are not displaying the picklist values but then picklist record values which may have redundency…lets take an example .

Controller

Out put: Here it is displaying the totla number of picklist values present in the records but not the picklist values present in it.

 one
To Resolve this we Use Map , By Using Map We can get all unique values in the map and we can store in list to display finally.
and the for this is

one
