FLUtilities

Usage

To run the example project, clone the repo, and run pod install from the Example directory first.

FLUtilities usage is based for dates, device specifications and model name, device token string, strings, UIAlertController, UIColor, UIView and a lot more.

Let's take example of Dates:

func add(months: Int) -> Date {
	var dateComponents = DateComponents()
	dateComponents.month = months
	let newDate = calendar.date(byAdding: dateComponents, to: self)
	return newDate ?? self
}

The above example is used to add to a month(s) to a given month.

func dayOfWeekFull() -> String? {
	let dateFormatter = DateFormatter()
	dateFormatter.dateFormat = "EEEE"
	return dateFormatter.string(from: self).capitalized
}

This method is to be used in case of getting a full name of a specific day, capitalized.

Just like that, you can use other methods to fetch number of months or days from a specific date, add or subtract to a day and month string, short or full.

Another example to be used for class name:

class func className() -> String {
	let className = (NSStringFromClass(self) as String).components(separatedBy: ".").last! as String
	return className
}

This method is used to convert an NSObject class name to string form.

Just like that, for strings:

public extension String {

	func capitalizingFirstLetter() -> String {
		let first = String(self.prefix(1)).capitalized
		let other = String(self.dropFirst())
		return first + other
	}
	
	mutating func capitalizeFirstLetter() {
		self = self.capitalizingFirstLetter()
	}
	
}

The above string based extension is used to capitalize first letter of any string, if used like below:

var name: String? = "nickelfox"
print(name.capitalizingFirstLetter())

Let's try working with UIAlertControllers:

	
class func showActionSheet(title: String?, message: String?, actionInterfaceList: [ActionInterface], handler: @escaping AlertHandler) {
	self.showAlertController(
		title: title,
		message: message,
		preferredStyle: .actionSheet,
		actionInterfaceList: actionInterfaceList,
		handler: handler
	)
}
	
class func showAlertController(title: String?, message: String?, preferredStyle: UIAlertController.Style, actionInterfaceList: [ActionInterface], handler: @escaping AlertHandler) {
	let alertController = UIAlertController.alertController(
		title: title,
		message: message,
		preferredStyle: preferredStyle,
		actionInterfaceList: actionInterfaceList,
		handler: handler
	)
	if let topController = UIApplication.topController {
		topController.present(alertController, animated: true, completion: { () -> Void in
		})
	}
}

UIAlertController.showAlertForMessage("Alert For Message Created Successfully")

UIAlertController.showActionSheet(title: "Title",
                                          message: "Title", actionInterfaceList: [interface1,
                                                                             interface2,
                                                                              interface3]) { }

The extension is used to show different types of alerts or action sheet like shared above.

An extension for colors is also present. Below is one example for it's usage :

var color = UIColor(red: <#T##CGFloat#>, green: <#T##CGFloat#>, blue: <#T##CGFloat#>, alpha: <#T##CGFloat#>)

After providing the respective float values for above arguments, the desired result will be obtained.

Now comes the usage of view, tableView, scrollView, collectionView, tableView and collectionView cell, images, etc.

To set tableView's or collectionView's backgroundView color:

self.tableView.backgroundViewColor = .clear

self.collectionView.backgroundViewColor = .clear

This piece of code sets tableView's and collectionView's background view color to clear.

A view's rounded corners can be achieved by:

self.view.roundedCorner(radius: 4)

You can also provide a string nibName to a UIView that returns a UINib, by:

self.view.nib(nibName: "ParentViewController")

If you check the example, you can also see helper methods to apply shadow or glow to a respective UIView. Also, an extension for UIImage to draw an image, fetch image with alpha or to get a tinted image with a color is also present. You can use it like mentioned below:

self.backgroundImage.imageWithAlpha(alpha: 0.5)

self.backgroundImage.imageTintedWithColor(color: .green)
