  • Usage

Instantiate and set delegate and dataSource as you know,

self.pickerView = AKPickerView(frame: <#frame#>)
self.pickerView.delegate = self
self.pickerView.dataSource = self
then specify the number of items using AKPickerViewDataSource,

func numberOfItemsInPickerView(pickerView: AKPickerView) -> Int {}
and contents to be shown. You can use either texts or images:

func pickerView(pickerView: AKPickerView, titleForItem item: Int) -> NSString {}
// OR
func pickerView(pickerView: AKPickerView, imageForItem item: Int) -> UIImage {}
Using both texts and images are currently not supported. When you implement both, titleForItem will be called and the other won't.
You currently cannot specify image sizes; AKPickerView shows the original image in its original size. Resize your images in advance if you need.
You can change its appearance with properties below:

var font: UIFont
var highlightedFont: UIFont
var textColor: UIColor
var highlightedTextColor: UIColor
var interitemSpacing: CGFloat
var viewDepth: CGFloat
var pickerViewStyle: AKPickerViewStyle
All cells are laid out depending on the largest font, so large differnce between the sizes of font and highlightedFont is NOT recommended.
viewDepth property affects the perspective distortion. A value near the screen's height or width is recommended.
After all settings, never forget to reload your picker.

self.pickerView.reloadData()
Optional: You can use AKPickerViewDelegate methods to observe selection changes:

func pickerView(pickerView: AKPickerView, didSelectItem item: Int) {}

CocoaPods:

In your Podfile:
pod "AKPickerView-Swift"

And in your *.swift:
import AKPickerView_Swift

            self.indicatorView1.numberOfCircles      = 15
            self.indicatorView1.maxRadius            = 40
            self.indicatorView1.delegate = self
           // self.indicatorView1.backgroundColor = UIColor.lightGrayColor()
            self.indicatorView1.startAnimating()

  • JDFPeekaboo is a simple class that hides the navigation bar when you scroll down, and shows it again when you scroll back up. It can actually be any UIView that it hides, and it will also hide a view at the bottom of the screen as well, if you like.

It's very easy to use. Simply add a property for it:

@property (nonatomic, strong) JDFPeekabooCoordinator *scrollCoordinator;
Then, set it up (say, in -viewDidLoad):

self.scrollCoordinator = [[JDFPeekabooCoordinator alloc] init];
self.scrollCoordinator.scrollView = self.scrollView;
self.scrollCoordinator.topView = self.navigationController.navigationBar;
self.scrollCoordinator.bottomView = self.navigationController.toolbar;
Sometimes, you may want to temporarily disable JDFPeekaboo, for example when you push another view controller onto your navigation controller. Some convenience methods are provided for disabling JDFPeekaboo (and re-enabling it).

The simple code to get SwiftSpinner running in your own app.

In case you installed SwiftSpinner via CocoaPods you need to import it (add this somewhere at the top of your source code file):
    import SwiftSpinner
When you want to show an animated activity (eg. rings are randomly rotating around):
     SwiftSpinner.show("Connecting to satellite...")
If you want to show a static activity indicator (eg. a message with two complete rings around it)
    SwiftSpinner.show("Failed to connect, waiting...", animated: false)
When you want to hide the activity:
    SwiftSpinner.hide()
That's all. If you want to change the text of the current activity, just call show(...) again, this will animate the old text into the new text.
