UILoader

Make it easier to track the loading status of your objects.

v0.7.0

Usage

Transform this:

class LameViewController: UIViewController
{
    @IBOutlet weak var activityIndicatorView: UIActivityIndicatorView?

    private var isPerformingVeryLongBackgroundTask = false
    func performVeryLongBackgroundTask() {
        self.isPerformingVeryLongBackgroundTask = true
        self.activityIndicatorView?.startAnimating()
        doStuff { [weak self] _ in
            if self?.isPerformingOtherVeryLongBackgroundTask == false {
                self?.activityIndicatorView?.stopAnimating()
            }
            self?.isPerformingVeryLongBackgroundTask = false
        }
    }

    private var isPerformingOtherVeryLongBackgroundTask = false
    func performOtherVeryLongBackgroundTask() {
        self.isPerformingOtherVeryLongBackgroundTask = true
        self.activityIndicatorView?.startAnimating()
        doOtherStuff { [weak self] _ in
            if self?.isPerformingVeryLongBackgroundTask == false {
                self?.activityIndicatorView?.stopAnimating()
            }
            self?.isPerformingOtherVeryLongBackgroundTask = false
        }
    }
}

Into this:

class CoolViewController: UIViewController, UILoader
{
    func didChangeLoadingStatus(_ loading: Bool) {
        if loading {
            //if you have a `UIActivityIndicatorView`, it will automatically start animating
            //disable buttons
            //do all sorts of stuff to your UI while you're loading things
        } else {
            //stop loading!
            //get on with your life
        }
    }

    //optional
    @IBOutlet weak var activityIndicatorView: UIActivityIndicatorView?

    func performVeryLongBackgroundTask() {
        self.isLoading = true
        doStuff { [weak self] _ in
            self?.isLoading = false
        }
    }

    func performOtherVeryLongBackgroundTask() {
        self.isLoading = true
        doOtherStuff { [weak self] _ in
            self?.isLoading = false
        }
    }
}

Requirements

iOS 9.0+ Swift 3.2

Installation

Cocoapods

Because of this, I've dropped support for Cocoapods on this repo. I cannot have production code rely on a dependency manager that breaks this badly.

Git Submodules

Why submodules, you ask?

Following this thread and other similar to it, and given that Cocoapods only works with Swift by adding the use_frameworks! directive, there's a strong case for not bloating the app up with too many frameworks. Although git submodules are a bit trickier to work with, the burden of adding dependencies should weigh on the developer, not on the user. 😉

To install Backgroundable using git submodules:

cd toYourProjectsFolder
git submodule add -b submodule --name UILoader https://github.com/BellAppLab/UILoader.git

Swift 2 support

git submodule add -b swift2 --name UILoader https://github.com/BellAppLab/UILoader.git

Then, navigate to the new Backgroundable folder and drag the Source folder into your Xcode project.
