Use an extension on String

Swift 3

extension String {
    func height(withConstrainedWidth width: CGFloat, font: UIFont) -> CGFloat {
        let constraintRect = CGSize(width: width, height: .greatestFiniteMagnitude)
        let boundingBox = self.boundingRect(with: constraintRect, options: .usesLineFragmentOrigin, attributes: [NSFontAttributeName: font], context: nil)

iAmrSalman

extension UIImage{
    convenience init(view: UIView) {

    UIGraphicsBeginImageContextWithOptions(view.bounds.size, view.isOpaque, 0.0)
    view.drawHierarchy(in: view.bounds, afterScreenUpdates: false)
    let image = UIGraphicsGetImageFromCurrentImageContext()
    UIGraphicsEndImageContext()
    self.init(cgImage: (image?.cgImage)!)

  }

Things can get quite messy when you have a complicated view hierarchy, like having multiple navigation controllers and/or tab view controllers.

This implementation puts it on the individual view controllers to set when they would like to lock orientations, instead of relying on the App Delegate to find them by iterating through subviews or relying on inheritance.

Swift 3

In AppDelegate:

/// set orientations you want to be allowed in this property by default

iAmrSalman

import UIKit

enum Theme: Int {
  
  case dark, light
  
  var dark: UIColor {
    switch self {
    case .dark:
      return UIColor().colorFromHexString("212121")

Here's how I got it working:

In AppDelegate.swift inside the didFinishLaunchingWithOptions function I put:

NotificationCenter.default.addObserver(self, selector: #selector(AppDelegate.rotated), name: NSNotification.Name.UIDeviceOrientationDidChange, object: nil)

and then inside the AppDelegate class I put the following function:

iAmrSalman

func setupCellSizing() {
  let layout: UICollectionViewFlowLayout = UICollectionViewFlowLayout()
  layout.sectionInset = UIEdgeInsets(top: 20, left: 0, bottom: 10, right: 0)
  layout.itemSize = CGSize(width: screenWidth/3, height: screenWidth/3)
  layout.minimumInteritemSpacing = 0
  layout.minimumLineSpacing = 0
  collectionView!.collectionViewLayout = layout
}
